Gyratory Crusher

Gyratory crusher is a large-scale crushing machine used for primary crushing of various hard ores or rocks, the feed material will be compressed, broken and bended through gyrating movement of breaking head within the chamber. The top of main shaft (assembled with breaking head) is supported within the bushing which is installed in the middle of spider arm; the bottom of the main shaft is mounted in the eccentric hole of bushing. The breaking head gives a gyrating movement around axis line of the machine while bushing rotating, and feed material can be crushed continuously, therefore it is more efficient than jaw crusher.

Features and Benefits of Gyratory Crusher:

Due to high reduction ratio, a smaller product size is produced. This puts less pressure on conveyor belt transfer points, which in turn leads to less materials handlings costs, less down-time and less maintenance costs.

Special liner & crushing chamber configuration produces more valuable cubically shaped, lumpy product and less fines.

Special design means crushers do not have to be choke-fed, simplifying plant design & eliminating the need for intermediate stockpile.

The use of spherical bearings instead of a bush arrangement, eliminates point loading in this area – longer bearing life, lower downtime, lower maintenance.

The spherical bearing results in more eccentric movement higher up in the crushing chamber, resulting in the effective nipping and crushing of very large feed sizes.

The spherical bearing allows for smaller gap settings at the discharge, leading to high set under & smaller product sizes.

Heavy duty gyratory design is ideal for crushing hard and abrasive material like iron ore.

Technical Data of Gyratory Crusher:

Note: The above capacities are based on an assumed feed where 100% ofthe feed passes 80% of the feed opening. 80% of the feed passes 60%of the feed topsize, and 50% of the feed passes a sieve size that is 10%of the topsize. The capacities are for feed materials with a bulk densityof 1.6 metric tons per cubic meter (100 pounds per cubic foot).All capacities are calculated at a maximum throw for each respective machine. All capacities are relative to individual application. Materialcharacteristics, feed size, distribution, work index, percent moisture,and feed method are factors when considering total crusher capacity.
