Hydraulic double roller crusher is a type of equipment used for crushing harder materials, including coal blocks. The double roller crusher controls the movement of the rolls through a hydraulic system, gripping the raw material between two counter-rotating rolls, and achieving the crushing of coal blocks through squeezing and shearing actions. The following is the general working process of the hydraulic double roller crusher when processing coal blocks:
Hydraulic roller crusher Feeding:
Coal blocks are conveyed to the feeding port of the double roller crusher, typically through a conveyor belt or other conveying systems.
Roller crusher Adjustment:
The hydraulic system is used to adjust the gap between the rolls, controlling the size and degree of crushing of coal blocks. By adjusting the position of the hydraulic cylinder, the distance between the rolls can be changed, thereby adjusting the compression and shearing effects on coal blocks.
Operation of Hydraulic System:
The hydraulic system controls the movement of the rolls by manipulating the hydraulic cylinder. This includes the rotation of the rolls, adjusting the gap, and maintaining the appropriate working pressure.
Squeezing and Shearing Actions:
The gap formed between the two counter-rotating rolls subjects the coal blocks to squeezing and shearing actions. These forces contribute to breaking the coal blocks into the desired particle size.
Discharging of roller crusher:
Crushed coal blocks are discharged through the outlet of the double-roll crusher and can be further processed or transported via a conveyor belt or other conveying systems.
Advantages include the ability to efficiently crush harder coal blocks, flexibility in adjusting the degree of crushing, and adaptability to larger coal chunks. However, operators should pay attention to maintenance and adjustments to ensure the safe and effective operation of the equipment.
The specific design and performance characteristics of double roller crushers may vary, so it is recommended to consult the equipment’s operation manual，and follow the guidance provided by the manufacturer when using hydraulic double-roll crushers to ensure proper operation and maintenance.
