be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-
Jaw Crushers MJ 90, MJ 110 and MJ 130 Technical Specification Jaw Crushers reduce large size rocks or ore by placing the rock into compression. This mechanical pressure is achieved by the two jaws of the crusher of which one is fixed while the other reciprocates. There are also primary and secondary types of jaw crushers.

The recycled aggregate was produced from natural aggregate concrete which were designed for M] 5 grade, moulded in 15 cms standard moulds, cured for 28 days under water and crushed at the age of three months, using a laboratory jaw crusher. The opening of the jaw crusher was set at 20 mm to have maximum 20 mm size recycled aggregate.
in gyratory crushers and to line the faces of jaw crushers but not to line rod mills or ballmills. More flow-resistant materials, namely, hardenable steels or cast irons, are used to line rod mills and ballmills. For over 50 years, alloyed white cast irons have been recognized …
One of the most important parameters is the angle between the two jaws, which is referred to as the nip angle. The nip angle is the angle at which the material, that passes through the crusher inlet to be crushed between the jaws can be gripped by the jaws without slipping. This angle depends on the size, hardness and frangibility of the material.

Table 4 shows the results of the experiment was carried out for all nine runs with each permutations of pH and copper ion concentration levels. For each test a 10% pulp was made using 100 g of coal and after adjusting the pH, the pulp was conditioned for 10 min.The require amount of copper ion was then added to the pulp and further conditioned for another 10 min.
This long term degradation in performance during the lifetime of the liners for flat angled crushers is well known and described e.g. for a 7-crusher by Andersen and Napier-Munn [11] and for a base supported crusher with 900 mm head diameter by Bearman and Briggs [14]. An example can be seen in Figure 7 in Paper E.
Blake type jaw crusher, primary crushers in the mineral industry; attains maximum amplitude at the bottom of the crushing jaws as the swinging jaw is hinged at the top of the frame.
