Roll crushers are simple in design and construction long lasting economical and versatile Roll crushing surfaces operate at a fixed distance apart as opposed to the continually changing distances in a jaw or cone crusher Product size is much more consistent
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.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit The ratio of reduction through a primary crusher can be up to about 8 1 Feed ROM up to m Product 300mm for transport to 200mm for SAG mill Feed
The LMRC100 Roll Crusher is typically used in laboratory or pilot plants after primary reduction of the infeed material Roll crushers operate with a minimum of dust generation and produce a material with a tight size envelope containing a minimum of fines.
MANUAL CRUSHER SELECTION 1 Determine the maximum feed size 2 The minimum feed size to the crusher must always be less than 25mm 1 in either open or closed circuit 3 Determine the total tonnage throughput of the crusher a Open Circuit Refer to capacity tables on previous pages detailing maximum and minimum recommended tonnages.

Calculate the theoretical capacity in terms of tons/hr The density of particles 2330 kg/m 3 and also calculate the maximum feed size Answer TC = tons/hr Feed size = m 23 What would be the diameter of the set of rolls in a roll crusher to take a feed of size equivalent to 3
Maximum feed size varies with each model but is generally limited to around 600–900mm The output gradation of the primary HSI crusher is generally coarser than the primary breaker due to the lack of expansion above the rotor which also affects the capacity.
Capacity TPH the above specification is an estimated performance of crusher The data in the table is for the performance of the crusher feed with the dry material with a specific gravity of 1600kg/m3 in an opened circuit operation also assumed the feed material s maximum size is under crusher s maximum feed size and does not contains finer material less than CSS.
