4. * 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 is 1/2 inch.

The Steele Smooth Roll Crusher plays a key role in bulk raw material preparation, processing clays, coal fines, coke breeze and gypsum waste. Twin rollers reduce pebbles and plastic lumps to form thin, flat discs, strips or sheets of material …
A smooth Roll crusher consists of two heavy metal rolls of the same diameter placed side by side each other in the horizontal position. The rolls are rotated towards each other at the speed. One of the shafts moves in fixed bearings …
Working Principle of Crushers. On left is a showing of the "standard gyratory with straight concaves" is a section through any vertical, radial plane in the crushing chamber of one of the intermediate sizes of the crusher. In order to understand the crushing action in such a chamber it is helpful to consider the process as though each step took place in an orderly, and …
The crushing rolls are driven individually and direct-ly by means of electro-motors or with coupling and gears, counterrotating via V-belts. The material is fed into the machine by means of conveyors while it is spread over the whole width of the roll. The roll diameter grants an optimum angle of entry. The
This chapter deals with the designs and operation of different types of roll crushers. Two main types are indicated. The first type where the rolls are rotated in opposite direction …
The roll crusher is mainly composed of fixed roller, movable roller, machine frame, shield, protecting guard. The machine is driven by the V-belt of the motor, which makes the two …
The unique crushing mechanism of tooth roll crushers results in less fines and a more uniform product size distribution. Easy to install and integrate: Tooth roll crushers are easy to install and integrate into existing material reduction systems. They can be mounted on a stationary or mobile frame, and can be integrated with conveyors, screens ...
McLanahan offers belt-driven Roll Crushers in four designs: Single Roll, Double Roll, Triple Roll and Quad Roll Crushers, which provide a substantial return on investment by operating at low cost and maximizing yield by generating …
The crushing body is formed by a rotating roll and an adjustable and spring-mounted crushing plate located on the oppo- site side. The distance between the base of the crushing plate and the tips of the roll crushers teeth forms the adjustable gap width, which can be varied depending on the required final grain size.

smaller sizes. Depending upon the feed and product particle size, the crushing operation can be classified as follows: 1. Primary crushing: The feed material is usually the run of mine. 2. Intermediate crushing or secondary crushing: The feed material is usually product of a jaw crusher. 3. Fine crushing or coarse grinding:
With Roll Crushers, of the material flow is processed between the roll bodies or roll and crushing plate. The space created between the width of the rolls and the distance from roll-to-roll or roll-to-crushing plate must be calculated using the following variables: Roll diameter Roll width Roll speed Gap setting Bulk density

The ore is fed from the upper part and the crushing is carried out in the gap formed between the two rolls. Since the use of multi-metal mine smooth roll face, so crushing effect mainly by crushing, grinding and some incidental effect (in the case of the tooth surface by chop main effect). The broken material is discharged by gravity.
