How to improve the grinding efficiency of Slag Grinding Mill

With the continuous improvement of the level of mechanization technology in China, Slag Grinding Mills are also developing towards large-scale, but the large-scale Slag Grinding Mill, coupled with the impact of Slag Grinding Mill equipment structure and process configuration, has led to ore dressing. The production cost of the plant is increased, the grinding efficiency is reduced, and SBM analyzes the reasons for the reduced grinding efficiency of the Slag Grinding Mill, and some solutions are proposed.

In the initial stage of production and operation of the Slag Grinding Mill, the hourly processing of raw ore is only 270t, and the utilization factor is low, and a series of measures to increase the throughput are adopted:

1. The sealing device of the center feeder is improved, the wear cycle and replacement cycle of the sealing pad are prolonged, and the phenomenon that the slurry is easily poured out to the mine end is avoided. The purpose of appropriately increasing the amount of ore and increasing the concentration of grinding is achieved.

2. The anti-helical height of the hollow liner of the discharge end is increased, and the ball stop is added. Increase the filling rate of the Slag Grinding Mill to nearly 42%, to make up for the problem of insufficient ball and difficult to break ore.

3. The parameters of the miner end of the Slag Grinding Mill were modified to solve the problem of slurry overflow, and the parameters of the cyclone were improved through experiments, the classification efficiency was improved, and the sand returning into the Slag Grinding Mill was reduced. the amount.

4. Use a Slag Grinding Mill with a smaller size. Due to the large size of the Slag Grinding Mill, the low speed can not achieve rapid crushing, affecting the grinding efficiency, increasing the driving power, resulting in an increase in the proportion of mechanical energy consumption. Therefore, considering the cost factor, select a device with a small size and low power consumption.

As a grinding equipment commonly used in concentrating plants, the Slag Grinding Mill has an important impact on the reduction of production costs of the concentrator and the improvement of production efficiency. Therefore, the concentrator should take reasonable measures to improve the Slag Grinding Mill. The grinding efficiency, at the same time the mineral processing plant when purchasing the Slag Grinding Mill, not only must consider the price factor, but also consider the structure, performance and other factors of the Slag Grinding Mill.
