Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.
The EDGE RS1500 roll sizer has been designed for the secondary and tertiary crushing of medium-hard, sticky and soft materials such as coal, lignite, clay, limestone and other bituminous and sub-bituminous materials. Boasting an impressive list of design features that includes a highly efficient hydraulic drive system, easy selective piece ...

The π, κ, ω-breakage process model is modified for breakage in a smooth double roll crusher. In previous papers, Austin (1971) modeled breakage in roll crushers and experimentally verified the models. Rogers (1983) extended the model for two component feed. The objective of the present paper is to find out a generalized selection …
Design and production of an indigenous roll crusher from locally available materials for low hardness rocks was carried out in this work. The throughput capacity of the machine was 1.43tonnes/hour. The theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%.

A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8.
Crushers may be divided into three general classes, with respect to the manner in which they do their work: Pressure Crushers: This category embraces the several types of gyratory crushers and jaw crushers, as well as the double crushing rolls, with either smooth or corrugated shells. Impact Crushers: This division is represented …
