Crushing equipment

Crushing equipment is the mechanical equipment used in the mineral crushing operations.

Broken homework often according to the size of the feeding and discharging granularity can be divided into coarse crushing, broken and finely. The equipment that the commonly used sand have jaw crusher, counterattack crusher, impact crusher, compound crusher, single-section hammer crusher, vertical crusher, gyratory crusher, cone crusher, roll crusher, double roll crusher, kandy crusher, a molding crusher etc.

According to the crushing method, the structure of the mechanical features of the action (principle) to differentiate, can be broadly divided into six types.

(1) the jaw crusher (tiger). Role is broken by periodic pressure to the moving jaw plate fixed jaw plate, will be caught in one of the crushed ore block.

(2) the cone crusher. Ore block between inside and outside two cone, cone fixed outside, inside the conical eccentric swinging, will be caught in the ore crushed, or broken.

(3) the roller crusher. Ore block in two opposite rotating round roll gap, mainly by continuous crushing effect, but also with grinding exfoliation, toothed roller surface and broken effect.

(4) the impact crusher. Ore block by rapid rotation of the moving parts of impact and was broke. Fall into this category and can be divided into: hammer crusher; Cage crusher; Counterattack crusher.

(5) grinding machine. Ore in rotating cylinder grinding medium (steel ball, steel rods, gravel or ore block) impact was crushing and grinding effect.

(6) other types of crushing grinding machine.

Mining machinery

Mining machinery is directly mining useful minerals and mining machinery and equipment used in the work, including: the exploitation of metal ore and non-metallic ore mining machinery; The exploitation of coal in coal mining machinery; Drilling for oil in oil drilling machinery. The first typhoon to move round piece of coal winning machine is designed by British engineers walker, about manufacturing success in 1868. In the 1880 s, in the United States, there are hundreds of Wells in steam power of impact drill drilling success, in 1907, and with rotary drilling rig drilling oil Wells and gas Wells, and since 1937, use it for open pit mine drilling.
