When we read the weekly news, there are often reports, so and so mountain spontaneous combustion fire, will make us very surprised to ask why will spontaneous combustion? In general, the mountain from the physical sense can be called gangue mountain, contains the composition of coal gangue, is available as a fuel material, often processed into fine sand, widely used in industry. So, how to make fine sand from coal gangue?
Coal gangue fine sand generally includes three steps, which are coarse crushing, fine crushing, sand shaping, different links need to use different processing equipment, choose the right equipment for the project can achieve twice the result with half the effort, here we recommend the use of LBY crushing, sand making equipment. Here we will explain the details of the three steps of coal gangue sand making according to the equipment of LBY company.
For coarse crushing, we use LBY’s jaw crusher, the motor of which feeds power to the pulley through the SPC belt, and the pulley drives the eccentric shaft to drive the moving jaw body to swing up and down back and forth. When the moving jaw plate is close to the fixed jaw plate, the volume of the crushing chamber decreases, and the material in the crushing chamber is squeezed or chopped; when the moving jaw plate is far away from the fixed jaw plate, the volume of the crushing chamber becomes larger, and the small pieces of crushed material in the crushing chamber are discharged from the discharge port.
For fine crushing, we use LBY’s HPT Hydraulic Cone Crusher or Impact Crusher, both of which have their own advantages, the most notable being the fixed spindle, the layer compression crushing mechanism, the Siemens PLC and touch screen control system, and the stable and intelligent operation capability. The most significant features of the Impact Crusher are the unique cavity shape to enhance crushing efficiency, the simple and quick hydraulic operation system, the quality materials to extend the service life, and the fine processing to ensure stable operation.
Shaping sand making link, after coarse and fine crushing of gangue and then transported to LBY’s sand making machine processing, and finally produce the bonding, good compressive resistance, angular fine sand.
