Smooth Double Roll Crusher

Toothed Double Roll Crusher

Toothed Double Roll Crushers are used for crushing of friable and brittle materials like Coal, Coke, Sinter (hot and cold), Clay, Earth, Slag, Chalk, Soft Limestone etc. Due to cutting action of the teeth, crushing of material takes place mostly due to shear and not by pressing. Therefore fines generation is bare minimum.

Description:

Crushing takes place due to two rolls running in to each other and crushing the material caught in the valley of the rolls. One roll is fixed, while other one is adjustable & spring mounted, permitting un-crushable material to pass through.

Crushing Rolls:

Toothed rings are mounted on the heavy fabricated hub and the rings are kept, in position by holding bolts. These rings are made of wear-resistant steel, like Manganese Steel, or any other hardened steel depending upon the application.

Drive:

Peripheral speed of rolls is kept between 3m-5m/sec and therefore up to 800 diameter roll crushers are driven, directly by V-belts. However, roll crushers above 800 mm diameter are provided with gear box/geared motor to keep the peripheral speed between specified limits of 3 m/ sec to 5 m/sec.

Housing:

Housing is divided in 3 parts and is made of welded construction :

• Heavy Duty Chassis with Legs.
• Yoke for Mounting floating / adjustable roll.
• Upper housing to keep the toothed roll crusher enclosed.

Gap Adjustment:

Gap Adjustment system is such, that during operation, gap can be adjusted along with the spring force. There are two spindles located one inside the other in such a way, that inner spindle tightens or losens the springs, while outer one changes the position of the roll.
