Roll Crusher - Mineral Processing & Metallurgy

These machines resemble in general form the roll crushers we have described, but they are of course much lighter, and their mechanical details are correspondingly simplified. Instead of the knob-like teeth used on the stone-breaking rolls, these coal crushers are usually fitted with spike-shaped teeth, and the action has more of a tearing nature rather than the heavy slugging and sledging.

Roll Crushers | McLanahan

Roll Crushers are one of the most widely used crushers in the mining industry and have numerous advantages, such as high capacity, low headroom, low horsepower, the ability to handle wet, sticky feeds and the generation of minimum fines while producing a cubical product.

Double Roll Crushers | McLanahan

Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale and wet, sticky feeds.

Roll Crusher - an overview | ScienceDirect Topics

Roll crusher operation is fairly straightforward: the standard spring rolls consist of two horizontal cylinders that revolve toward each other (Figure 6.14(a)). The gap (closest distance between the rolls) is determined by shims which cause the spring-loaded roll to be held back from the fixed roll.

Design, Fabrication and Testing of a Double Roll Crusher

2.1 Roll Crusher Geometry It is necessary to estimate the maximum size of the mineral particles that can be fed into the machine for a known roll diameter, roll length and roll gap. It is convenient to assume that the particle is spherical and the roll surfaces are smooth when calculating for the maximum size of the particle feed.

Lancaster Products - Roll Crusher for Glass Manufacturing

Lancaster Products Roll Crushers are designed for long life with a minimum of maintenance. These crushers reduce – in a single pass- material previously requiring primary and secondary crushing. The crushing rolls turn toward each other, confining all crushing to the area where the teeth mesh.

Crusher - Wikipedia

This mechanical pressure is achieved by the two jaws of the crusher of which one is fixed while the other reciprocates. A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker .
