PRC series coarse crusher

General

This equipment is mainli used for crushing of brittle materials with medium-hardness such as raw coal,lime stons in heat-engine plant,metallurgy,mining and chemical foelds,including also material crushing,medium crushing or fine crushing.

Working principle

The equipment is mainly consisted of motor,hydraulic coupling(coupling device),breaking machine,monitoring panel, hydraulic system and electric system.through hydraulic coupling,the motor triggers the crushing rotor to rotate at high speed.When the coal chunks goes into the breakingmachine, they are crushed under the impact of ring hammer rotating at high speed,meanwhile,the chunks are

also bounced against crushing board ang sieve board at high speed.in addtion,there are also impact and abrasion among the chunks,so the coal matenal is repeadly crushed.After crushing the material flows from top downwards under the shearing force and the compaction between the ring hammer, sieve board and crushing board.The crushing process is continuous to meet the required granularity and finally the material is discharged through the output. theimpurities such as iron and wood are divided by the ring hammer into impunty chamber,which shoud be cleaned on a regular basis.
