Gyratory Crusher an overview ScienceDirect Topics

A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening. Hammer crushers are used either as a one-step primary crusher or as a secondary crusher for products from a primary

Gyratory Crushers Mineral Processing & Metallurgy

The action of the gyratory crusher, Therefore it is practicable to use close-grained cast iron, and special high-test mixtures of cast iron, for these parts, if the machine is intended for crushing soft or medium materials. When very hard and tough materials are to be crushed, the machine is usually strengthened by substituting cast steel in one or more of its parts. Wearing parts in the

2. GYRATORY CRUSHERS

The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine, and its product normally requires additional crushing before produc- ing the final product. The gyratory crusher is a pressure crushing device as is the jaw crusher. The crushing action itself is

Gyratory and Cone Crusher ScienceDirect

01/01/2016· 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 performance of gyratory crushers may be

Optimization of primary gyratory crushing at Highland

The research was aimed at understanding gyratory crusher liner wear in the overall context of the crushing process. Wear measurements were taken for in-service crushers during the research period using a novel laser profile measurement device. Data from the wear measurements was correlated with crusher production information such as current draw and throughput. This work resulted in enhanced

Tips for maintaining efficiency in crushing circuits Quarry

03/01/2019· Cone and gyratory crushers. Cone crushers and gyratory crushers are also compression-type machines that crush material between moving and stationary pieces of steel. The setting between the two pieces of steel controls the output. Though the chamber is round in shape, the moving piece of steel is not meant to rotate. Instead a wedge is driven around to create compression
