Portable Rock Crusher
Technically, portable rock crusher(also called mobile rock crusher/portable stone crusher machine) is a set of flexible, easily-transferred and self-contained equipment combination of devices installed in stone crushing plant and sand making plant for material feeding, crushing and screening. Besides, this kind of mobile rock crushers are widely used in gold mining that's why sometimes they are also called gold mine portable rock crusher. It could be classified into two variations: semi-portable stone crusher (moving through mounted way) and tracked crusher, according to the way it moves down roads.

Portable rock crusher is designed to mainly crush coarse minerals like gold and copper ore, metals like steel and iron, glass, coal, asphalt, gravel, concrete to name but a few.
Do We Have to Drive a Pile for a Portable Rock Crusher?
Portable rock crusher is a kind of equipment which could move down roads over wheels or crawler to operation site for processing materials without a pile driven and prepared (Pile Driving is to sink piles into deep ground to offer an extremely stable foundation for the building above). A complete mobile crusher plant commonly consists of wheels/crawler, a fixed crusher, sometimes grinder or pulverizer, vibrating screen, movable crusher frame, which not only perfectly demonstrates a self-contained and agile structure, but also unveils the versatility of crushing and screening.
Flexibility highlights and separates portable rock crushers from the stationary. A portable rock crusher is available for various terrains and could be driven by both diesel fuel and electric generator, which implies that power supply won’t be such a challenge for the places where a mobile stone crusher machine is launched. (Analysis of investment on power supply will be elaborated on later)
Budget on a Portable Rock Crusher
How much will it take to invest a mobile rock crusher? Do you want to buy rock crusher? Different types of rock crushers have different yields. Hongxing Machinery portable rock crushers for sale provide different modes to meets customers needs. And different types have different price according to their yield. Besides, many other factors are influencing the prices of the portable rock crushers for sale.
-Manpower and freight cost
The workers and facilities assigned on pile driving could be cut down because there is no need to prepare one for a portable rock crusher. In addition, a portable rock crusher for sale usually comes with a PLC controlling system to offer a simple operation, and three men could get it under control at site—one takes charge of maintaining, one is the loader driver, and the last is in charge of real-time supervision, which explains why it’s said that a mobile rock crusher is a money saver in terms of manpower cost. As far as the freight cost goes, a lot of investment could also be saved. For a mobile rock crusher could be driven to operation site and gotten in production immediately, not to mention that it could deliver end products to where they are wanted to be.
According to research, it costs 70 RMB (11 dollar) to truck a ton of granite in China. That’s to say approximately 11000 dollar needs to be spent only in delivering 1000 tons of materials, let it alone adding the end products freight cost. While a portable rock crusher will spare users from such kind of worry, compared with a fixed crusher, as in what’s shown in the chart below.
|Portabel Rock Crusher||Fixed Crusher|
|Workers required at site||3||More than three|
|Feright cost of materials||None||11/t*1000t=11000 dollar|
|Summary||A large sum of freight cost could be saved through a portable rock crusher with great flexibility|
-Factors influencing the price of a portable rock crusher
Besides the quality of a crushing machine, the price is always concerning users most, when it comes to buying a mobile rock crusher. Then what’s the price of a portable rock crusher for sale?
Product Quality: it’s often said that price depends on quality, so is in the case of a portable rock crusher. The better the quality of a portable rock crusher is, the higher its price is, for it could bring users higher efficiency, greater return on investment, and more convenient maintenance. More importantly, only a manufacturer pulls more advanced technology and high-quality materials as well as more senior engineers on researching and designing such high-end product can an unrivalled mobile stone crusher come into being.
Supplier: there are agents and mobile stone crusher manufacturers who both supply portable rock crusher for sale in the domestic and foreign market. The agents usually refer to those people who buy products from manufacturers and sell them to end buyers to withdraw a sum of commission during the whole transaction, while the portable crusher manufacturers are those people who make products and directly sell them to end buyers. Obviously, portable rock crushers price of the former is much higher than from the latter, so figuring out which supplier is worthy of cooperating with for a long time before spending money on such a product is wise and necessary.
Market: with the booming development of construction, cement and chemistry industry, this kind of more flexible and mobile rock crusher is in greater and greater demand in the market, which has created a stage where some of manufacturers play a villain role in lifting the price of portable rock crusher to a new bar to squeeze as many profits as possible. Thus choosing a perfect timing to get mobile rock crushers with competitive price is also important and advisable.
-Investment on power supply of portable rock crusher
Lots of people might be wondering how a portable crusher for sale could be driven to move, is diesel fuel, generator, or both of them? The answer obviously turns out to be both of them.
Diesel engine: the engine which is usually affiliated with the equipment is started with diesel fuel consumption to generate power used for a portable rock crusher to move and crush. From Google, a database penetrating every walk of life, it is easy to learn that about 210 grams of diesel fuels has to be consumed for per kilowatt of electricity and 800 grams of them make a liter even. Then in China, each liter of diesel fuel is sold for 6RMB (1 dollar), a number almost coinciding with that in the international market.
Generator-driven pattern: in China, a 100kw generator could produce 1 kilowatt of electricity per hour, and 1 KWh industrial electricity needs to be paid approximately 1 RMB(0.6 Dollar) for, as well as a 100kw generator sold for 40,000-50,000RMB (5,953-7,400 Dollar). It’s clear to summarize that a pair of 100kw generator backups will cost users the least of 12,000 dollar. It should be noticed that if the generator-driven pattern is more suitable for an operation site, getting generator backups prepared ahead is definitely an awesome action.
|Extra Charge||None(a complete machine commonly has its own diesel engine )||40,000-50,000RMB required on a single generator of 100kw|
|Summary||Diesel Enginer is the best choice for short-term projects while generator is for long-term ones|
|PS: 'kwh' stands for 'kilowatt hour'; 1RMB=0.15 Dollar; 40,000-50,000RMB=6,000-7,500 Dollar|
From the diagram, it could be seen that the former pattern is more fitting for short-term projects, and the latter one is better used in long-term projects. Actually, each of power supply patterns has its own two sides. Generator-driven pattern proves how to be friendly to environment where human reply on and could help users skip some trivial procedures, but raises a higher standard on operating cost; while diesel engine turns out to be more economical, but inevitably causes air pollution to environment. So which kind of method to take is determined by the final requirements.
-Portable crusher price and rock crusher machine maintenance cost
As one of key parts of investing, the portable rock crusher machine maintenance cost mainly lies in turning the old and worn-off wearing parts into new ones. As a matter of fact, when it comes to maintaining some kind of crushing equipment, it’s all about changing the worn-off spare parts. The only difference is that each kind of machine gets its own wearing parts with different qualities and prices, which cause different prices of mobile crusher lines. For example, it does take more investment to maintain a portable cone crusher than a portable jaw crusher, because the cone crusher wearing parts comes with higher quality and longer service life than those of a jaw crusher. Thus mobile crusher price and maintenance cost are going to be taken depends on what kind of wearing part is in demand.
All in all, purchasing a portable rock crusher is just as important as choosing the right crusher manufacturer.
Where Does a Portable Rock Crusher Work Best?
Portable rock crusher is a combination of crushing machines like feeder, crushers, transportation and screening equipment, just like a complete production line. With large capacity stone feeding bin and stone screening equipment.
Besides making a good budget prior to buy a portable rock crusher, it is relatively important to figure out where the best part of it could be shown thoroughly.
Compared with the other ordinary crushing machines, a mobile crusher plant could not only show a good performance under the environment better for a stationary crusher, but also play an irreplaceable role in the short-term project that is operated in a complicated and terrible environment, or needs to be occasionally transferred from one location into another one for processing purpose. A portable rock crushering machine is a better choice for the people who are planning to make a higher bid, as currently advanced technology and premium materials have to be adopted to make it such a flexible rock crusher then inevitably lead to an increase in the price of it. What's more, there are many mobile crusher manufacturers who can draft the plans for you.
Portable rock crusher has excellent mobility and adaptability of the working site, and it does not need much pre-preparation before the installation of the portable rock crushing station. Except that, the mobile rock crusher also has many remarkable advantages, such as high crushing efficiency, strong bearing capacity, stable operation, convenient maintenance and so on.
China Hongxing is a professional crusher manufacturer. The crusher equipment includes cone crusher, jaw crusher, impact crusher equipment, etc. There are many cheap crusher machines for sale. You can have a look at the product center, such as crushing equipment, mobile crushing plant; construction waste disposal equipment; sand washing equipment; conveying screening equipment.
A portable rock crusher machine is more of a qualified helper for recycling construction waste and concrete in cities, especially for some small operation sites where construction waste piles up dispersedly, which could be explained through three easy-understanding reasons.
- A portable rock crusher could move flexibly with the help of wheels or movable frame;
- With a self-contained structure, a mobile crusher machine is capable of crushing and screening materials at the same time, which effectively simplifies the procedures of processing wastes and reduces operating cost;
- A portable rock crusher could directly march into operation site to turn construction waste into something valuable due to its great agility, which significantly avoids dust pollution during the course of waste delivery.
- A mobile rock crushering machine with screen greatly improves safety and efficiency.
Moreover, a portable rock crushering machine is able to effectively ease industrial sand shortage through offering abundant premium manufactured sand and has been playing a chief role in current infrastructure construction industry.
How to Make a Portable Rock Crusher Eco-friendly?
Environmental protection is the practice of protecting the natural environment by individuals, organizations and governments. Its objectives are to conserve natural resources and the existing natural environment and, where possible, to repair damage and reverse trends. --Wikipedia
It reveals that taking prompt actions to protect environment has been the mainstream. Then how to make a portable rock crusher eco-friendly?
With the increasing attention paid to environment protection, stricter and stricter requirements have been put on a variety of enterprises supplying mining machines. In order to keep down dust and noise level of a portable rock crusher in the middle of running, some methods could be implemented as below:
Dust-proof measures: an amount of dust mainly appears and flies around a portable rock crusher doing crushing. In order to avert such phenomenon causing severe air pollution to environment, a new cavity design offering great sealing performance, with addition of sprayer, has been adopted in making the advanced movable crusher to effectively prevent dust from snapping out and put restraints on dust rising separately during the whole processing, which successfully illustrates how eco-friendly a portable rock crusher could be.
Noise-proof methods: noise proofing for a portable rock crusher equipment is mainly reflected on turning down the noise source and adding noise-isolation cover. Take a portable impact crusher for example, it’s feasible for engineers to optimize manufacturing technique and adopt materials making lower noise when researching and developing the portable impact crusher to keep down the noise source through relieving machines’ vibration and friction. Besides, with the help of noise-isolation cover assembled on the impact rock crusher, noise could be significantly turned down when the machine is crushing and processing materials.
Apart from all of these ways to control dust and noise, a mobile rock crusher equipment also unveils good eco-friendly feature, which could be illustrated from two aspects: natural resources conservation and high efficiency. The former is attributed to its self-contained structure that takes less space to conserve land resource, and the latter is thanks to that it could move along routines to make it to the operation site where raw materials could gets crushed then. This could save adequate investment on transporting materials to the site for users and do little harm to environment, not to mention its convenient maintenance, powering saving and great return on investment.
How to Choose a Portable Rock Crusher in Terms of Capacity?
A portable rock crusher could be at its most effective condition when the capacity is arranged at 80-400t/h, for its space-limited frame for containing and supporting other equipment pulls certain standard on the fixed crusher used with it, which indicates that a fixed crusher is not fitting for the carrying frame if its biggest capacity is under 80t/h or above 400t/h. A small or mini fixed crusher cannot take too much more of vibration and friction, while a big one fails to fit in the frame of a portable rock crusher. Therefore, if some projects such as coal mining, gold mining are located in the terrible environment, a 80-400t/h portable rock crusher equipment will be the best choice because of its flexibility and great efficiency. Otherwise, a fixed crusher is the most suitable one because it offers lower operating cost.
What Kind of Material does a Portable Rock Crusher Serve Best?
As opposed to a fixed crusher, a portable rock crusher for sale is not perfect for processing a large number of materials in large size. Because it happens to team up with a stationary crushing equipment to work together, like portable jaw crusher and portable impact crusher, portable cone crusher(used in secondary crushing) and the feeding opening designed for material entry is supposed to coincide with the feeding size of the stationary crusher whose total weight and dimension need staying in accordance with the frame, otherwise, numerously oversize materials fed into the machine will result in severe clogging condition even unexpected downtime.
How about the Process and Installation of a Portable Rock Crusher?
Actually, the installation of a portable rock crusher primarily follows several simple steps: delivering the machine to site—installation—soft operating (without materials)—soft operating(with materials), and it could be literally put into operation if each of steps proves nothing abnormal. Sometimes, with the help of some manufacturers who is known for free one-stop service including product delivery, installation and personnel training and etc, it won’t take more than a week before getting a portable rock crusher into mass production. Just like a fixed crusher, a mobile rock crusher equipment should be maintained every 20 hours in order to guarantee its uptime.
- Delivering the machine to site
- Soft operating (without materials)
- Soft operating (with materials)
Recommendation of Portable Rock Crusher Types
Semi-portable crusher (also for semi-mobile crusher) consists of two main parts: moving parts and working parts. The moving part includes chassis, legs and oil tank, and the working part is fixed on the former part and contains a fixed crusher and power units such as electronic control system. Only with the help of a tractor can a semi-portable crusher move flexibly.
According to research, the biggest semi-mobile crusher with capacity of 300-400t/h could extend to 17-18m in length, while the smallest one with capacity of 50t/h can only do to 12-13m.

|End Product||With fine size and premium quality, it’s end products are easier to get recycled|
|Tire Configuration||Dualaxial, Triaxial|
Tracked Crusher is literally a kind of portable rock crusher or mobile stone crusher. With a tracked chassis, tacked crusher could move even make a turn flexibly under the remote control of PLC system touchpad. Like a semi-portable crusher, a tracked crusher could process 50-400tons of materials per hour as well.
Even though tracked crusher is not as good as a semi-portable crusher in terms of stability and efficiency, it could move freely without traction force and demonstrates greater mobility and agility than semi-portable stone crusher.
Secondly, tracked/portable stone crusher is more easily-transferred, because it takes advantage of crawler to move flexibly and only needs the least time and manpower to get delivered to operation site with the remote control of intelligent PLC system touchpad.
Lastly, the chassis of tracked crusher is designed in a fully rigid tracked structure looking like a ship and reveals the following characteristics: good rigidness, unrivaled flexibility and great acclimation for mountains and wetlands. All of these features enable a tracked crusher to climb mountain to reach operation site, which makes it more perfect for mountain stone mining and open coal processing.
Respective Features of Main Drive Modes of a Tracked Crusher
|Drive Mode||Power Source||Pros||Cons|
|Direct drive plus hydraulic drive||Diesel engine||Compact structure and high efficiency||It takes much more operating cost than power dive mode|
|Direct drive plus power drive||Diesel engine||Convenient maintenance||High operating cost|
|Full-hydraulic drive||Diesel engine||Simple layout and operation with low operating cost||Mainly works well for small tracked crushers due to relatively higher running speed|
|Power drive||Diesel engine drives hydraulic pump sets to drive motor to generate power for movement||Low operating cost and simple maintenance||Urban power supply is not widely available|
|Urban power supply is not widely available||Urban power supply or diesel fuel||Low operating cost: urban power supply could be adopted in big projects to reduce operating cost, while more flexible diesel engine is for small projects||Complicated structure causes high manufacturing cost and leads to difficult maintenance|
