Vertical grinding limestone grinding production process and environmental protection measures

Vertical grinding limestone grinding production process and environmental protection measures

1. Production process of limestone in

  • Vertical Roller Mill
  • grinding production

     

    The source of limestone is generally a large-scale mine. After the blasting of the mine, the falling bulk material passes through the crushing action of the crusher, and then through the grinding effect of the vertical roller mill, the limestone powder for industrial use is obtained, so the production process and its The crushing and grinding are inseparable.

    After the blasting, the large limestone material needs to be crushed by the crusher, and the crushing equipment is broken, broken, etc., and the limestone crushed by these crushers will become small pieces of material, and these small pieces The material can be put into the mill for milling.

    The crushed limestone will be transported to the silo by the hoist and then transported to the vertical roller mill mainframe by the closed dosing machine. The limestone powder after the main mill grinding will be blown in the hot blast stove. The hot air of the system is blown to the classifier. After the powder selection by the classifier, it is collected by the dust collector to obtain the finished limestone powder material.

    In the production process described above, the flow direction of limestone and the fineness of limestone material are the same, and these are the same processes as those of vertical roller mill in limestone milling.

    2. What environmental protection measures have been taken in the production of limestone milling?

    In the case of regular limestone crushing and milling, in order to protect the environment, sometimes in order to prevent noise pollution, two devices will be installed to prevent dust and noise pollution.

    Regarding the dust problem, two kinds of dust collecting devices, such as a dust collector and a dust collector, are installed in the milling production line. The function of the dust collector is to collect the powder material, and the dust collector is installed behind the powder collector, and it is used in addition to In addition to collecting powder materials, it also prevents the powder material from leaking into the air. As for the noise problem, it is only necessary to install two mufflers in the production line.
