Crusher an overview ScienceDirect Topics

Mechanical Crushing and Grinding. Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Crushers. Crushers are widely used as a primary stage to produce the particulate product finer than about 50–100 mm in size. They are classified as jaw, gyratory and cone crushers based on compression, cutter mill based on shear and hammer Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.Developments in iron ore comminution and classification

THE EFFECT OF LINER WEAR ON GYRATORY

The bonded particle model approach for rock breakage modelling was further developed with real rock particle shapes based on 3D scanned rock particles in a study where the liner wear on a primaryIn this paper, based on the coarse broken iron ores in the rotary crusher, the ore particle model was established by using DEM software. The dynamic characteristics of the model were simulated by combining with the three-dimensional cone crusher model in order to study the influence of relevant parameters on the performance of the crusher. 5.1.Chamber Optimization for Comprehensive Improvement of Cone Crusher

Gyratory and Cone Crusher ScienceDirect

A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer’s data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.d. It is required to feed the ore with a uniform particle size, otherwise the crusher is easy to be blocked, and the miner must be set before crushing. e. It is suitable for crushing massive ore, and sometimes the discharge particle size is too large for strip or flake ore.
