Mobile crusher is the machine that has crusher, feeder, feeding hopper, belt, driving and controlling systems on mobile chassis.
Shaking table is a kind of ore separating machines, mainly for separating ores like tin, tungsten, gold, silver, lead, zinc, tantalum, niobium, iron, manganese, titanium and coal, etc.
Flotation cell, also named as flotation machine, is of great importance for ore separation. The flotation effect can be influenced by the factors of ore particles, ore pulp or drug.
The Compound cone crusher(Symons cone crusher) is suitable for crushing materials with medium hardness or above.
Different ores have different magnetic coefficients. Magnetic separator is just the machine that uses magnetic and mechanical power to separate the ores from mixers.
The Single-Cylinder Cone Crusher is widely used for medium, fine and superfine crushing operation of mine, aggregate, metal ores, limestone, granite, basalt, river gravel, construction waste, steel slag, cement raw material, ceramic raw materials.
The Vibrating Screen is called circular vibrating screen because of its movement trajectory similar to a circle.
Cone crusher is the machine that is made up of two cones. Cone crusher is suitable to crush medium-hardness or harder ores and rocks.

Borehole breakdown occurred when the initiated fracture became unstable after significant growth with 0.76 cm 0.3 in. to 7.62 cm 3 in. in length. The test results showed that all drilling muds had a tendency to seal narrow natural fractures or fractures induced by high borehole pressure.Learn More
The objective was to determine the optimum borehole mining plan and system for mining coal seams less than 10 feet thick that pitch more than 25 degrees. Of the methods considered, the double-drill method was selected for further study. This method uses a larger vertical hole for the pumping tool and a smaller slant hole for the cutting tool.Learn More
