Structure
European coarse grinder consists mainly of frame, rotor, hammers and grizzly bars.
The frame includes upper part and lower part, which are welded by steel plates after
cutting, the remaining parts are bolted into one.
Working principle
The host drives the main shaft through the motor and V-belt driven spindle to rotate the rotor,
generating the centrifugal force, then driving all hammers stretch around. The bulks of material feed
into the crushing chamber, will be crushed by the hammers at a highspeed movement. The broken
material requested will be passed the grizzly bars at the lower part and discharged, the unbroken rest
will be left in the chamber to be crushed repeatedly by the hammers and iron plates until it can reach
the requested standard. To avoid clogging, the water content of the material to be crushed not more
than 5%.
Application
It is widely used in metallurgy, mining, chemical, cement, coal gangue, construction,
sand, ceramic, etc. It is mainly suitable for crushing various soft and hard ore whose
compression strength is not higher than 320Mpa.
