4 ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing Roll crushers have a theoretical MAXIMUM reduction ratio of 4 1 If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch
The McLanahan Triple Roll Crusher is composed of two basic elements— In this single unit coal and other variable materials can be reduced in a single pass to sizes as small as 1/2" Special rolls can be provided for finer crushing This crusher produces a more uniform product with a minimum alloy iron or steel toothed rolls
： A discrete element method DEM model of the crushing process of a toothed double roll crusher TDRC is established using the bonded particle model DEM results and experimental data are compared quantitatively and a relatively good agreement is

Magaldi Single Roll Crusher features a toothed roll assembly which crushes the incoming feed material against anvil plates When the material enters through the inlet chute the teeth of the rotating cam shear and split the chunks against the anvil plates The crushed material is cleared and dropped down through the crusher outlet chute into
In coarse comminution double roll crushers DRC are used for the size reduction of blasted materials and in secondary comminution In the primary crushing stage DRC with toothed rolls are of particular importance In contrast to smooth rolls these offer improved nip conditions so that larger particles can be nipped and crushed
The ERC roll crusher series comprises four units ranging from the ERC 18 14 entry model to the top end ERC 25 34 model with throughputs ranging between 600 and 10 000 tonnes/h The first ERC for commercial operation the ERC 25 25 capable of generating an output of 8 000 tonnes/h has already been sold and was shown at the bauma trade
3 When the gasket number decreases the gap between the two rolls become small and the discharging granularity will get small Package and Delivery The roll crusher should be processed to be rustproof and moisture proof before delivery The small parts are packed into wooden crates; the big parts are wrapped by plastic sheeting Company Overview
