Coal Gangue Crusher
Coal gangue was activated by means of calcination in seven temperature ranges. Systematic research was made about activation mechanism and structural evolution. Glycerin-ethanol method, SEM, MIP and XRD were used to determine the variation of structure and activation of coal gangue during the calcination. The experimental results show that because of heat treatment in the range of calcination temperature, mineral composition and microstructure of coal gangue are changed. In addition, its activity is improved evidently. The amount of lime absorbed by the sample calcined at 700 °C is 2–4 times that by uncalcined coal gangue in the course of hydration. When NaOH is added to coal gangue-lime system, hydration reaction of the system is sped up and the microstructure of hydrating samples of coal gangue is improved.
Coal Gangue Application and Processing
Recovery of coal and pyrite. Through simple techniques, from the gangue in the coal washing well chosen, selected by screening from low quality coal, and pick out of pyrite. Recovery of coal can be powered by fuel, washing waste rock can be used for building materials, and pyrite can be used for chemical raw materials. 2. Used for power generation. 3. Manufacture of building materials: bricks instead of clay as raw material can be dug less fertile. Brick, the use of coal fuel itself, can save coal. 4. Coal can also be used to produce low calorific value gas, manufacturing ceramics, making soil amendment, or used for paving, underground filling, filling the ground to create farmland. After the waste dump on the spontaneous combustion can also be planting grass, landscaping. Comparing with other traditional stone crusher, coal gangue crusher has excellences for fine crushing, high productions and low maintenance. The long force arm designed into the cone provides greater crushing force. And the spring release system generates more opposing force than other traditional stone crushers. So coal gangue crusher is used widely in coal gangue processing industry.
Coal Gangue Crusher
Coal Gangue Crusher is used for crushing alloy, ferrosilicon powder, caps, cans, PCB, mobile battery and brittle metal material .
coal gangue crusher features:1. Saving the energy2. The higher production efficiency3. The lower noise, less dust
fine coal gangue crusher is a machine which is utilized to crush the coal, it is the most suitable to crush each brittle materials, like coal, gangue, coke, slag, red sandstone, shale, loose limestone, etc. The compressive strength of the material does not surpass 100MPa; the moisture content does not surpass 15%.
It has the following features: saving the energy, guaranteeing the discharged material size, the higher production efficiency, the lower noise, the less dust and so on. Otherwise, the discharge opening can be adjusted according to the customer’s requirements.
Coal Gangue Crusher Working Principle
Hammer crusher is an impact rotor-type crusher with hammer ring. The materials are impacted and crushed by the high-speed rotating hammers after entering the chamber. The crushed materials get the impetus energy from the hammers, and then they will impact on the crushing plate. After the secondary crushing process, the materials fall on the sieve plate. Then the materials are crushed again after being sheared, extruded, and grinded, and then dropped out. Unbroken matters enter the metal collector, which are cleaned periodically.
