Vertical Roller Mill for Coal

Vertical roller mill for coal grinding requirements for production line

Vertical roller mill developed by our company can be used in grinding of coal production, but many clients understand, coal mine is a kind of inflammable and explosive product, so we in the coal pulverizing, each of the equipment in the grinding powder production line have some special requirements, this article is based on the requirements for a simple introduction for you. Coal is a kind of fuel, is a kind of fuel, we often see a fuel, and since then it has the characteristics of flammable, but many clients also should understand, it is not only the characteristics of flammable in ore grinding powder production, because of the fineness of pulverized coal is small, so under certain conditions, also has the characteristics of explosive, so the grinding of the coal powder production has been faced with great danger.

Our company is engaged in the mining grinding machinery manufacturing for many years, have learned the characteristics of coal in the flour, so we for the sake of safety for coal pulverizing, therefore in the coal vertical roller mill in the powder production line design some special requirements. Is our main equipment used in production of coal grinding roller mill machine, and the use of this equipment rather than other types of products, the main reasons for the coal flour production because of its safety performance is higher, and the safety performance is some rigid requirements for flour production line by us.

First, in the coal grinding powder production, the customer must be installed in vertical slow powder production line, hot blast stove, because the hot blast stove is a fuel after combustion flue gas, so the oxygen content in flue gas is lower, and oxygen is necessary for coal burning, so through the installation of hot blast stove, we can reduce the oxygen content in the production system, and improve the safety factor of production. Second, in the use of vertical roller mill for grinding powder production, vertical milling machine machine top have explosion-proof valve set, the explosion-proof valve is to avoid an accident involving the pressure was too high in the system, when the system pressure is too high, the valve will first burst, so as to release the pressure in the system, finally realizes the safety production. Finally, in vertical slow powder production line, the feeding device using the enclosed quantitative feeding machine, which is one of our rigid requirements, and the requirement is for the sake of negative pressure system along with oxygen and prevent outside air into the system and preparation, so the customer can't literally change the feeding device.
