Application :
Toothed Double Roll Crushers are used as primary as well as secondary crushing of the 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, permising of uncrushable 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 1 4% Mn Steel, K.M.D. or any other hardened Steel depending upon the application.
Drive through V belts or through Gear Box/Geared Motor.

• No foundation is required thereby saving no costs.
• After crushing is over the plant can be kept back in a shed, thereby eliminating the need for extra security personnel at the site.
• For people whose working site changes very frequently this mobile crusher is the right choice. more...
Smooth Double Roll Crushers are normally used as Secondary & Tertiary Crushers where narrow spectrum of grain analysis is desired, i.e. with given setting say "S" Most of the product gains lay near to "S". Reduction Ratio less than 1:4 and rolls can be set to 0.5 to 0.8 mm. Feed size, setting & roll diam are to be so selected that the material gets nipped.
In order to get the best results, material should be fed centrally into the valley formed by rolls, uniformly, continuously throughout the width of rolls, at a velocity very near to surface velocity of rolls. One roll is fixed and other roll is floating spring loaded or hydraulically loaded to kick-back in the case of overload or uncrushable coming into crushing zone and same roll can be moved closer or away to get the desired gap. See gap setting arrangement. Rolls are made of Mn (14%) steel or K.M.D. Steel.
We also manufacture Four roll crusher on request.
We have designed rotopactors to handle large quantity material and selectively reduce their particles into desired sizes. This process in executed very quickly and efficiently. The finished products obtained from this process are technically & comfortably acceptable to any authority, which include NHAI, MOST or DAM Construction. The entire process is based on the principal of Impact Crushing with stone to metal breaking at high speed. The material reduction capacity of our rotopactors shown in the table may vary with speed, weight per cu. & mtr & size of desired products. This above shown capacity is based on bulk density of material i.e. 1600 kg/cu mtr.
Roll crushers are used for minimizing “fines” generation and/or to handle wet, sticky materials that could not be easily done with the traditional primary crushers. more...
