Double Roll Crushers can be used for primary and secondary crushing. Each roll assembly comprises of renewable and reversible toothed segments, bolted and keyed to a robust hexagonal hub with the nuts inside the hub. Locking nuts are securely located in fabricated pockets in the drum. This enables removal and replacement of segments from the outside using only one tool. The feed material should enter the centre of the gap between the two rolls and spread across the full roll width for maximum efficiency and this ensures a uniform product size distribution.
In order to improve the quality of the brick and tile products, clay after double double roller crusher, the number of required size greater than 3 mm should not exceed 10%.To achieve this effect, can take the following measures:
1. Control the moisture content of sludge.The moisture content of sludge is unfavorable and exorbitant, generally should be controlled under 15%, or form a mud pie, impact crushing efficiency and crushing effect.
2. The rational selection of model and control double-roll crusher feed diameter. In general, double roller crusher roller diameter, should not be less than the broken clay particle size 9 times, before being 9 or higher r D, good crushing effect can be attained.
3. When it is necessary to adopt double roller system process, namely two double roll crusher separately of coarse and fine crushing and fully guarantee the quality of crushing.
4. Concave keep proper roll gap.Two roller clearance should be kept between 3 ~ 5 mm, clearance is too large, shall promptly repair or replace, or impact crushing effect.
5. The feeding uniformly. Suddenly not overcharge, sludge is best can fall on the whole roll width, in order to reduce uneven wear of the rolls.
