Toothed roll crusher

　　Spike crusher is mountains and rivers in reference to foreign advanced mechanical equipment, combined with domestic production of the new high efficiency crushing equipment industry.This crusher is applicable to coal, metallurgy, mining, chemical industry, building materials industries such as more suitable for the large-scale coal mine and coal preparation plant raw coal (coal gangue) broken.Product's performance is very stable and efficient, has small volume, big crushing ratio (5-8), low noise, simple structure, convenient maintenance, the advantages of high productivity than now in China (2 PGC toothed roll crusher high productivity - 2 times), have been broken material granularity and the crushing rate low, easy maintenance, overload protection, safe and reliable, etc.With limited distance between the crusher motor and reducer type hydraulic coupler, prevent dynamic overload, sensors, overload protection, safe and reliable.Hydraulic roller spacing adjustment, tooth roller bearing lubrication.Tooth profile optimization design, shear selection and broken, high efficiency low, the grain of uniform.
