Working principle of gyratory crusher

gyratory crusher form a critical transition between the mine or quarry and the plant. Drilling and blasting produce material feed in a broad range of fragmentation, whether it is iron ore, copper ore, limestone or any other material. Most large operations depend on gyratory crushers to reduce the material to a manageable size suitable for the crushing or processing plant. As a key link in the process, these crushers must be chosen to meet capacity and performance requirements. Reliability and service support for years to come are equally important. And with a commercial life of several decades, the technology should also be suitable for future expansions, process changes or variations in feed material.

Gyratory crusher is composed of transmission, engine base, eccentric bushing, crushing cone, center frame body, beams, original dynamic part, oil cylinder, pulley , appliances and dry oil, thin oil lubrication system components etc..

gyratory crusher Working Principle:
The motor of gyratory crusher is forced by eccentric sleeve through belt pulley or coupling, driving shaft and the cone to oscillate and rotate around a certain axis, so as to make the crushing wall close to and far away from surface of the liner plate fixed on the adjusting sleeve. The ore is crushed by continuous impact, extrusion and flexural action in the crushing cavity.

gyratory crusher Application:
The crushing movement of gyratory crusher is ongoing continuously. So it working efficiency is higner than jaw crusher. Until the early 1970s, large gyratory crusher already can handle materials 5000 tons per hour, the biggest feeding diameter can be 2000 mm. Gyratory crusher is one of the main equipments for primary crushing ores or rocks on metallurgy, building material, chemical industry and hydropower etc. industrial sectors.
