The compound crusher machine(also called combination crusher) is a piece of important crushing equipment for fine crushing, which is also known as compound sand making machine.
Combination crusher is mostly used for secondary crushing of medium and low hardness materials with high work efficiency and high yield. HXJQ Machinery compound crushers for sale are combined with the advantages of both hammer crusher and impact rock crusher. This crusher machine is a kind of sleeveless and adjustable fine crushing equipment. In addition, the compound crushers have a wide range of applications, especially suitable for hard limestone, dolomite, granite, and basalt.
The crushing ratio of the composite crusher is large, and the maximum crushing ratio can be adjusted to the granularity of the discharge. The compound crusher machine will not be affected by the wear of the hammer and the lining. The elastic adjusting mechanism can be used to automatically discharge the unbreakable materials without causing damage to the equipment.

The compound crusher machine is mainly to crush the stone materials, which has a high degree of wear and pressure withstand. At the same time, long-time usage of compound crusher machine will inevitably be dusty, which will affect its normal operation. If the dust in the crusher machine is too much, it will be resulting in a shortened service life of the compound crusher machine. Therefore, it is necessary to inspect and maintain the crushing equipment on a regular basis. Here’s the combination crusher routine maintenance:
How to maintain the compound crusher machine
The first thing is a daily inspection. The daily inspection of the compound crusher machine is to check the work condition before and during the operation. Check the wear and tear of the parts, whether the bearing lubrication is good, whether the fasteners or bolts are loose, and whether the discharge size of the machine equipment is uniform. Check whether there is abnormal vibration inside the crushing machine and whether the temperature of the composite crusher is normal or not. It must be checked carefully and done well, otherwise, it will cause failure and affect normal work.
Lubrication work is also of great importance. Lubricating oil is used to reduce the friction and damage of the crushing equipment. This requires no impurities or other impurities in the lubricating oil. The bearing oil needs to be injected into the entire space solvent with a grease gun. Be sure to pay attention to the temperature of the lubricating oil during the operation in order to avoid excessive temperature and burn out parts.
Next, better dust removal effect. According to the service life of the filter material and the pulse valve, it is necessary to consider the dust of the ash. In order to improve the comprehensive dust removal effect of the compound crusher and the belt machine, when crushing dry materials, water is properly sprayed at the material inlet of the compound crusher machine(required to be carried out 10 to 20 minutes after the combination crusher being started).

The bag filter at the corner of the compound crusher machine and belt conveyor should be updated to LNGM64-4 and LNGM4-8 respectively. According to the characteristics of dust, water and oil repellent filter materials are used. The LNGM4-8 bag filter should be used in the open air, and its housing is insulated and waterproofed. Different types of dust collectors are configured according to different needs of customers.
Improve the process layout of the bag filter, arrange the dust collector of the compound crusher according to the direction of the belt conveyor. Convert the standard type ash bucket of the bag filter into a double ash bucket structure, thus canceling one screw conveyor, raising the bag filter, which is beneficial to the arrangement of the air inlet pipe. In addition, the air inlet box is arranged at the air inlet to make the dust of the composite crusher feed port directly enter the air inlet box of the dust collector, saving the elbow system resistance and improving dust collection efficiency.
Strengthen the management of dust removal device, regularly check the airtight cover, and find problems in a timely manner. Implement target management assessment on the dust emission of the post environment and bag filter, regularly conduct dust monitoring, use economic leverage to mobilize the work enthusiasm of the post personnel, improve the maintenance level of the dust removal equipment, and minimize dust pollution.
The structure characteristics of compound crusher machine
- Large crusher ratio. The maximum crushing ratio can be adjusted to the discharge particle size without being affected by the wear of the hammer and the liner.
- No sieve bar setting. It is not easy to block when crushing materials with high moisture content and large mud content.
- The elastic adjustment mechanism is adopted, and the unbreakable materials can be automatically discharged without causing damage to the equipment.
- The bearing is horizontally arranged and has a long service life, which can crush materials with high temperature (such as cement clinker)
- The structure of the rotor body of the machine is unique. When the material is being crushed, the rotor body is hardly worn.
- The rear cavity is provided with a screw or hydraulic opening mechanism, and the consumables can be easily replaced without using the main equipment.
Combination crusher machine working principle
The massive ore falls from the feeding hopper into the upper feeding tray in the upper crushing chamber, and the material is thrown toward the inner wall of the cylinder by the centrifugal force of the feeding tray, and collides with the counter-attack plate installed on the inner wall, and the materials collide with each other. After the material enters the conical rotor cavity, it falls spirally in the conical space. After punching and pressing, the existing cracked ore is further crushed.
Due to the inclination between the conical rotor and the lining plate, the smaller material is forced to migrate downward, and the classification and breaking are automatically realized from large to small. The material is struck by the hammer in the conical rotor cavity, and the high-speed running block material collides with the counter-attack plate again, and the material flow collides with each other to cause the material to be crushed, impacted, sheared and crushed, thereby improving the crushing efficiency.
There are many advantages of HXJQ compound crusher machine
The advantages of the compound crusher machine
- Simple and reasonable structure and low operating cost. Using the stone principle, smaller wearing.
- High crushing rate and energy-saving. With fine crushing and coarse grinding function, the compound crusher is suitable for crushing medium and hard materials.
- It is affected by the moisture content of the material and the moisture content can reach 8%. In addition, the impeller self-lining wear is small and easy to maintain.
- low noise, less pollution. The working noise is lower than 75 decibels (DB level), and the dust pollution is less; the product is cubic, the bulk density is large, and the iron pollution is extremely small.
- High production efficiency, large processing capacity. The compound crusher machine has the functions of fine crushing and coarse grinding, and it is more suitable for crushing hard materials.
- long life of wearing parts, low consumption. The wear cycle of the roll skin is long, and the wearing parts adopt the new high-strength wear-resistant materials in China, which can crush high-hardness materials, which can bring considerable economic benefits for customers.
Some matters need to be paid attention during operation
- If an emergency occurs during operation, it should be stopped to check. Before the faults removing, the combination crusher machine should not be started.
- When entering the internal inspection of the machine, must pull off the power switch and hang up the nameplate that someone is checking. Before the inspection, the materials in the upper part of the crusher machine should be cleaned to prevent it would be falling and hurt the people. After the test is completed, the upper cover must be covered and the bolts should be tightened.
- All safety devices must be complete and secure. When the contact signal and communication equipment fail, the compound crusher machine cannot be started.
