Crusher equipment as the main mining equipment, mainly for the different sizes of crushed stone, crusher equipment are jaw crusher, impact crusher, hammer crusher and cone crusher equipment. In order to meet the needs of breaking the high strength and high hardness micro carbon ferrochrome in metallurgy, mining, construction and other industrial sectors, CHAENG developed the multipurpose crushers.
Crusher is generally used to deal with larger pieces of material, and product size is coarse, usually greater than 8 mm. Its structural feature is that there is a certain gap between the broken pieces, and they do not touch each other. Crusher can be divided into coarse crusher, middle crusher and fine crusher.
The working principle is as follows:
According to the crushing methods and mechanical structure characteristics (action principle), they are divided into six kinds in general:
(1) Jaw crusher (tiger mouth). Its moving jaw plate periodically presses to fixed jaw plate to crush the ore sandwiched between them.
(2) Cone crusher. The ore block is between the two inner and outer cones, the outer cone is fixed, the inner cone is eccentrically swinging, and the ore block between them is crushed or broken.
(3) Roller crusher. The ore block is mainly subjected to continuous crushing in the slot between two opposite rotating round rollers. This kind of crusher also has grinding and stripping functions, and its toothed roll surface also has a splitting action.
(4) Impact crusher. The ore block is crushed by the impact of the rapidly rotating moving parts. This category can be divided into: hammer crusher; cage crusher; reaction crusher.
(5) Grinding mill. The ore is crushed by the impact and grinding functions of the grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder.
A. roller mill: grind material by rotating rollers.
B. Pan mill: use rotating disc with vertical or horizontal axis as a crushing part.
C. Centrifugal mill. Take use of centrifugal forces between high speed rotating parts and grinding medium to perform crushing action.
D. Vibrating mill. Take use of the high frequency vibration produced by rotating shafts, so that the grinding medium and materials strike against each other and crushing action is realized.
Various crushers have different specifications and different ranges of use. Jaw crusher or gyratory cone crusher is usually used for coarse crushing; standard cone crusher for medium crushing; and short head cone crusher for fine crushing.
