Mining operations are applied in a lot of professional mechanical equipment is roughly divided into mining equipment, processing equipment, and prospecting equipment. Mining machinery is directly used in mineral exploration and rich selected operations such as machinery, including mining and mineral processing machinery. Prospecting machinery working principle and structure and mining machinery is mostly the same or similar, generalized said is also a kind of mining machinery. Mine homework also used a lot of crane, conveyor, fan and drainage machinery.

Mining equipment

Tunneling machine/steak bottles machine/belt conveyor/reprint machine, crusher, etc of coal shearer drum shearer, plough, bending scraper conveyor, since moving type hydraulic support, the bridge stage loader and the telescopic belt conveyor/hydraulic support/scraper conveyor, etc

Including the exploitation of metal ore and non-metallic ore mining machinery; Drilling for oil in oil drilling machine drum shearer, plough, bending scraper conveyor, since the move type hydraulic support, bridge stage loader and the telescopic belt conveyor

Mineral processing equipment

According to the ore dressing process can be divided into broken machinery (cone crusher, jaw crusher, box type crusher, counterattack crusher, etc.), grinding machine, screening

Sieving equipment

Sieving equipment

Machinery, sorting (optional) and dehydration machines, as well as a variety of production lines, etc. The sorting machinery according to the mechanism can be divided into gravity separation, magnetic separator, flotation machine, and special processing machinery. Mineral processing machinery is also used in building materials, chemical industry, glass, ceramics and other industrial sectors. Dressing is in acquisition of mineral raw materials, according to a variety of minerals, physical and chemical properties, physical properties and chemical properties, select the useful mineral process. Implementation of this process is called mineral processing machinery, processing machinery by the beneficiation process is divided into crushing, grinding, screening, separation (optional) and dehydration machine.

Crushing machine commonly used have jaw crusher, gyratory crusher, cone crusher, roller crusher and counterattack crusher, etc.; Grinding is the most widely used in mechanical cylindrical grinding machine, including rod mill, ball mill, pebble mill and the grinding machine, etc.; Screening that is commonly used in mechanical inertia vibrating screen and resonance screen; Hydraulic classifier and mechanical classifier is widely used in wet graded homework grading machinery. Sorting machinery according to the mechanism can be divided into gravity separation, magnetic separator, flotation machine, and special processing machinery. Sorting machinery is the earliest in gravity separation, the original piston jig in 1830 ~ 1840 in Germany, for metallic ore separation; The first magnetic separation machine (with weak magnetic separator) appeared in 1888. Flotation machine appear relatively late, the first mechanical agitation type flotation machine appeared in 1910. Gravity separation machinery is the use of ore and waste rock in density and particle size differences, in moving medium separation equipment, including jigging machine, heavy media separation and centrifugal separator. Jig is with the aid of the diaphragm or piston or compressed air to form the water in the tank water, so that in mineral grains under the action of pulsating flow on sieve according to density, granularity theory. On the density of particles through the sieve bed rock layer, gathered in the bottom of the tank be concentrate, by row ore mouth eduction. Used for separation of metallic ore are mainly trapezoidal jig, double room moving cone bottom jig and complex vibration jig; Used in the coal side drum jig and sieve jig air chamber. Heavy media separation machine is the use of suspension or heavy liquid as heavy medium, separate the ore and waste rock. Mainly has dense medium vibration chute, heavy liquid medium spin, inclined round heavy medium coal washer and round of heavy medium coal separator. Centrifugal separator is used in the recovery of fine slime in metallic ore grain machinery, mainly consists of two parts, host and control mechanism. On the host cone drum generated by high speed rotating centrifugal force field, the heavy mineral particle deposition to the drum wall be concentrate, light particles attached to concentrate on the surface, affected by flow membrane (pulp flow), discharge drum, as tailings. Magnetic separator is the use of a variety of mineral magnetic differences, with the help of magnetic force and mechanical force on the role of mineral separation machinery. Magnetic separator by the magnetic system, sorting device, feed and discharge device. Magnetic separator is a lot of more phyletic, basically have permanent magnet drum magnetic separator, magnetic ring strong magnetic separator and high gradient magnetic separation machine, etc. Flotation machine is the use of ore grain surface physical and chemical properties, separation of fine mineral machinery. Ore flotation reagents and flotation machine attached by compressed air or mechanical stirring, that is not easy to be water wetting mineral grains attached on the bubbles (positive flotation process), rose to a liquid surface, through the concentrate discharge exhaust device, easy to be water wetting mineral grains in tub as in tailings discharge. Wet dressing concentrate need through dehydration machinery processing, in order to make solid and liquid separation. Dehydration machinery can be classified as thickener, filter machine, centrifugal machine and drying machine. [1]

Prospecting equipment

Mainly include drilling machine, rotary vertical drilling machine, derrick (derrick), winch, engine, electric motor, diesel engine) and mud pump and other equipment, and manipulator and screw machine and other ancillary equipment.
