Ore mill is a mechanical equipment used for grinding ore processing. Ordinary ore mills include Raymond mills, ultra-fine mills, and vertical mills. These ore mills It is an indispensable key mechanical device in the development of industry, metallurgical industry and chemical industry. Shanghai Joyal Mining Machinery Here, we talk about the requirements of the temperature of the milled material that the ore mill needs to pay attention to. The temperature of the grinding mill has a great influence on the ore mill. Joyal is simple and we talk about it. .

The temperature of the material entering the mill has a great influence on the output of the mill. If the temperature of the material entering the mill is too high, the temperature inside the mill will be too high and the grinding efficiency will decrease. Due to the continuous impact and grinding of the material by the grinding body, a large amount of heat is generated, so that the cement fine powder easily adheres to the grinding body and the liner. If the temperature of the clinker is high, the amount of heat that is brought into the mill is large, so the temperature inside the mill is higher, and the phenomenon of adhesion of the fine powder is more and more serious, which prevents the operation of the ore mill.

In general, the smaller the fineness of the ore material, the more pronounced the effect of the temperature on the grinding of the ore mill. An increase in the temperature inside the mill will cause dehydration of the gypsum, which will cause the aggregate to fail to meet the requirements. The actual situation shows that when the clinker temperature exceeds 80°C, the mill output will decrease. Therefore, when grinding cement without admixture or a small amount of admixture, the temperature of the clinker into the clinker should generally be controlled below 100°C.

Ore grinding machine may increase the temperature of the grinding mill after grinding in the process of grinding the ore. It may also cause the bearing temperature to rise. The grinding body will cause deformation of the liner of the ore milling machine due to the thermal stress. , bolts break. As the bearing heats up and the lubrication is reduced, it is possible that the bearing of the alloy melts and an equipment accident occurs.
