Gyratory Crusher Components . Gyratory crushers were invented by Charles Brown in 1877 and further developed by Gates in 1881 (they were commonly referred to as a 'Gate's crushers' in the early years). A primary crusher is designed to receive run-on …
Selection of the crusher required a great deal of design regarding to the mine planning. Selection of suitable primary crusher from all of available primary crushers is a multi-criterion decision making (MCDM) problem. The present work explores the use of technique for order performance by similarity to ideal solution (TOPSIS) with fuzzy set theory to select best …
In the aggregate industry, primary crushers are used to break down larger rocks and stones into smaller particles, while secondary crushers are used to further refine these particles into the desired size and shape for …
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: …
The content provides comprehensive information about various types of mining crushers, their components, workings, advantages, and applications.
A jaw crusher usually wears more manganese steel per crushed tonne than a gyratory crusher. Feeding fines into the crusher may increase peak stress loads because of packing ? ie material being compacted as far as it compacts. This is enhanced by moisture, which again is highest in the fines and quite common in underground mines.
When choosing the best crusher for your primary, you first have to consider the application details. Desired product size, capacity, HGI, percentage of rock, and hardness of the rock in the feed are some of the factors that dictate the selection of primary crushing equipment.. Since many of the available types of crushers cross over application lines, other …

How you select the best primary crusher from all of the available primary crushers is required a great deal of design based on the mining plan and operation input. Usually, capacity, feed size, product size, rock compressive strength, abrasion index and mobility of crusher are considering as criteria, and in practice usage, gyratory, double toggle jaw …
In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle ...
Primary crushing is the first stage of material reduction and can sometimes be the only stage needed to generate the desired product for a job.
