I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged. Both of these statements are true, but the degree to which the product is

Gyratory Crusher an overview ScienceDirect Topics. Gyratory crushers are principally used in surface-crushing plants. The gyratory crusher (Figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve.
Gyratory crushers can accept 8–10% moisture in operation, but the fine content should be preferably less than 10%. The crushing action in gyratory crushers is regarded as rings or ‘helics’ (spirals) of feed down through the crusher of which a single section may be regarded as similar to the jaw crusher. Therefore, computations leading to
The residence time of material in the crushing cavity of a conical/gyratory crusher is controlled by providing the crusher with a flow restricting arrangement at the lower end of the crushing surfaces. The flow restricting arrangement includes a frustum, ledges or ring of outwardly directed fingers provided at the lower end of the mantle, which fingers are interspaced with inwardly directed
Due to their design, cone and gyratory crushers are limited with regard to the feed size and the achievable reduction ratios. On mobile plants, cone crushers are used predominantly in the secondary and tertiary crushing stage.
Diagram of a gyratory crusher [image: 135-5-16)] Gyratory Crushing Action. Designs of the breaking faces vary with manufacturer. As a result, the product size distribution varies. When the feed drops into the crusher, the mantle squeezes the rock against the concave surface.
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.
