Jaw Granulator

Jaw Granulator

REW Jaw Granulators are heavy duty and have Grease lubrication system. These crusher are designed for long life service with minimum maintenance for hard, tough and abrasive material, including Ferro Alloys. The principal of crusher is on the basis of compression on rock against metal..

Jaw Granulator is usually used as Secondary crusher in quarry production lines, mineral ore crushing plants and powder making plants. It can be described as obbligato machine in mining, building construction, construction wastes crushing, Hydropower and Water Resource, railway and highway construction and some other industries.

Working Principle

The strip and strip pulley are driven by a motor, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the movable jaw runs down, then the materials are crushed into pieces. It will become bigger when the movable jaw runs up. The movable jaw board leaves the fixed jaw board under the action of pole and spring , then the end products come out from the crushing cavity.

Standard Features

The body of "REW" Granulators grease lubricant type Crusher is made from tested MS plates with welded construction duly reinforced.

The swinging lever (pitman) is fabricated out of MSplates with high tensile strngth and it is annealed by heat treatment process and then it is precision machined for smoth crushing stroke. the crankshaft is made of forged steel and fitted in heavy duty spherical double roller bearings, which ensures smoth operation. the two bearings are fitted on both sides of the crankshaft and two in swinging lever which are well sealed against possible etry of dust.

The crushing Jaw plates are made of high tensile Manganse Steel. One jaw plate is fixed and other jaw plate is fitted on swinging lever. the setting of jaw plate is carried out by simple adjustment with tie rod at the bottom of the swing jaw stock. the setting is altered and adjustment can be made without stopping the machine.

Heavy duty cast iron flywheels are fitted on both the ends of crank shaft. These flywheels are machined all aover, counter weight fitted and balanced to ensure steady crushing force.

The Granulators shall be complete with side plates, Toggle plates, Toggle bearings, Toggle block, Wage block and foundation bolts etc.


Granulators is widely used in various materials processing of mining & construction industries, such as it is suit for crushing granite, marble, basalt, limestone, quartz, cobble, iron ore, copper ore, and some other mineral & rocks.
