We have coal gangue por le crusher supplier,Coal crusherplant andgangue crusherhas bigger reduction ratio, and the biggest reduction ratio can reach any adjustment of discharging granularity without being affected by plate hammer and liner abrasion. Types ofCoalCrushers. There are many kinds ofcoalcrushers according to differentcoal crusher manufacturers.
The coal gangue is slightly harder than coal, so it can be crushed by the stone crusher suitable for the materials with middle hardness. The hammer crusher of Dingli has no grate, which can greatly reduce the material clogging. Currently in the market, Dingli's hammer crusher has been top choice for many customers to crush gangue.
Jaw crusher. After the action of the jaw crusher, more coal gangue particles larger than 4.75 mm are collected. After screening, the difference of the calorific value of various particle sizes is very small, and the separation effect is just so so.

May 01, 2020· Therefore, gangue with a particle size below 50 mm was selected for this test, and the particle size distribution of the coal gangue sample after crushing is shown in Fig. 3. To prepare the test samples, the gangue was crushed with a hammer down to 80 mm particles and then further crushed to 50 mm particles using a small crusher.
Methods: The hydraulic counter-roll crusher directly separates large pieces of coal and underground gangue such that large pieces of coal gangue do not escape from the well. The electric machine built-in roller crusher is an explosion-proof electric machine used in the crushing roller.
Coal gangue identification flowchart. Technical features ※ Wide processing size range: It can handle 30- 600mm raw coal. The upper limit of separation is 600mm and the lower limit is 30mm. ※ High separation accuracy: The rate of gangue removing is over 95%, the rate of coal in gangue is less than 2%, and the separation effect is significant.
Jaw crusher. After the action of the jaw crusher, more coal gangue particles larger than 4.75 mm are collected. After screening, the difference of the calorific value of various particle sizes is very small, and the separation effect is just so so.
It has uniform particle size, low crushing rate, convenient maintenance, sensitive overload protection, safety and reliability. Applicable to coal, metallurgy, mining, chemical, building materials and other industries more suitable for the crushing of raw coal (including vermiculite) in large coal mines or coal preparation plants.
At present, coal gangue is a solid waste with large emission in China. If it is treated directly, it will pollute the environment, may also cause spontaneous combustion, resulting in accidents, we can achieve the purpose of waste reuse through the coal gangue crushing treatment, so as to save resources, and protect the environment.
