Double Roll Teethed Roll Crusher

30/03/2018  The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll

Double-toothed Roller Crushers for difficult Materials

11/03/2014  The processing system of the double-toothed roller crusher makes it possible to crush any type of raw material from hard (limestone and rock) to soft (clay, soil and mud) or even elastic-like wood or rubber tyres. The rotation speed, especially if compared to traditional crushers, is very low; so low, in fact, that tip speed is under 3 m/s.

MBE

The anticipated maximum feed size determines the roll diameter. The size of the desired product can be fixed by the adjustable gap width between tip and bottom of tooth. The throughput rate is a function of roll width, gap width and peripheral speed. Both swings systems are carried in the base frame. The crusher rolls are hollow cylinders with ...

DOUBLE ROLL CRUSHER (SMOOTH ROLL,

The double roll type of crusher pinches the aggregate only once. To avoid excessive wear upon the roll tyres, it is important that the pinch should be immediate, positive and without slippage. Consequently, larger feed sizes should be avoided, and the ratio of reduction should be kept within the 3 to 1 limit. Any attempt to exceed the permissible ratio of reduction c causes slippage which ...

What is a roll crusher? – Mineral processing equipment

The feeding rate should be proportional to the rotating speed of rolls, as blocks should be feed to the crusher at the tangential speed rate of rolls. For smooth types, the roll diameter D should more 22 times than the feeding largest particle d to get a reduction ratio 1/2 or 1/3 (D>22d), or more 26 times to get 1/4 reduction ratio (D>26d). Types of roll crushers. There are two types of roll ...
