The Recent Technological Development of Intelligent Mining
(2) Intelligent mining is a revolution for coal production because of its high ratios of investment and profit, energy conservation, safety, fewer people, and greater efficiency. (3) The level of China’s electromechanical manufacturing industry and intelligent control technology has been greatly promoted by research into intelligent miningcoal and waste rock from the required height on a hard floor. Coal and waste rock grains, being more fragile, are crushed when dropping. The dense grains of the waste rock remain intact or broken to a small extent [21,22].

Understanding the Cone Crusher Working Principle: How It
The cone crusher’s unique design allows it to rotate at high speeds and crushes material through a combination of compression and impact. When the cone crusher is in operation, the spindle rotates around its own axis, causing the mantle to move back and forth. The mantle is the cone-shaped part of the crusher that moves in a circular motionCoal gangue is a black-gray solid waste with low overall carbon content and is harder than coal discharged from the coal production process. The traditional reuse is to pave it, do ground filling or make land, etc. Nowadays, with the improvement of recycling technology, it is used for building materials such as refractory bricks, gangue cement, Which Crusher is Better for Coal Gangue Crushing?

Coal Crushing: New-type Toothed Roll Crusher VS
The raw coal of large particle size and high hardness contains a large amount of vermiculite. The raw coal is first crushed to below 300mm by the jaw crusher, and then crushed to below 70mm by a toothed roller crusher, and then transported to the coal storage bin by the belt conveyor. After screening, the final product of 25~70mm is sold to 300 tons/hour double roller limestone mobile crushing and screening production line started at Malaysia project site. Crushed material: limestone Input size: ≤300mm-500mm Ouput size: ≤90-100mm (0-20mm, 20-40mm, 40-90mm, 90-100mm) Capacity: 300 tph Good news came from Tangshan Tianhe’s Malaysia project site that Double Roller Crusher, Coal Crusher, Limestone Crusher
