Types of Rock Crusher for Mining Use

[Jim Wu]

Mining crusher is also called rock crusher for mining use, which refers to the crushing machine whose discharging granularity is more than 3 mm account for more than 50% in total discharge capacity in layout. Crushing work includes rough crushing, middle crushing as well as fine crushing according to the size of the feeding and granularity. The sandstone equipments that the commonly utilized are jaw crusher, strike crusher, compound crusher, vertical crusher, spiral crusher, double roll crusher, etc.

Adjustable fine crusher mainly consists of rotating part, guard board part and tank. There are several hammer carriers which are cross and non-overlapping sequence on wheel core of the rotation part. Hammer head is fixed on the hammer carrier, and the width of hammer is larger than that of the hammer carrier and outline, and the wheel core is welded as a whole body by a number of contours, fixed on the spindle. Both ends of spindle are supported on the rack by hydraulic bearing. Guard groups divide into several pieces to fix on the tank, protecting the body from the wear and tear, and forming counterattack crushing cavity of different forms. The latest adjustable fine crusher equipped with hydraulic equipment can carry put maintenance work in a very convenient way for the interior fuselage to save a lot of time cost for the users.

Jaw crusher is the equipment of the first choice for primary crushing. It has characteristics of large crushing speed, accordant product granularity, brief structure, reliable running, simple keep, low operation costs. Thus it is used in mining, building materials, smelting, railway, water conservancy, highway and chemical industry and other sectors.

Jaw crusher uses squeezing and bending effect and coarse crushing as well as intermediate crushing materials of all kinds of types. This kind of crusher is widely utilized in mining and china industries because of its simple composition, trustable operation and ability that is able to crush hard materials. Jaw crusher needs less investment and lower production cost than cone crusher. And as for hammer crusher, the antiwear feature of jaw crusher has longer service time, higher production efficiency and smaller investment.

Impact crusher, commonly known as sand maker, is the equipment has one class level all over the world, using of the famous "stone hit stone” crusher principle and technology of an American company together with the practical position in sand production of the world to R&D. And its performance has an important function that cannot be replaced by other ores fine crushing machines. It is the most efficient, realistic and stone crushing machine that can be trust.
