It is better to buy stone powder grinding machine through the nearest grinding equipment factory, so as to fully understand the performance of stone powder grinding machine. So how to judge the quality of stone powder grinding machine? In the field inspection mainly observe the size, hardness and moisture of the grinding material, followed by the stability of the stone powder grinding machine, and then the pressure resistance of the stone powder grinding machine.

First, the impact of grinding materials on the stone powder grinding machine

Grinding material refers to the material processed by the stone powder mill. From feeding to discharging, the whole processing process has a great impact on the stone powder grinding machine. It mainly includes the following effects:

1, the impact of material hardness on stone powder grinding machine

The hardness of the grinding material is usually distinguished by Mohs hardness (1-10), the type and content of inclusions in the raw ore are different, and the grinding difficulty is also different, in general, the higher the hardness of the material is the more difficult it is to grind, and the greater the wear and tear of the stone powder grinding machine, so the hardness of the material is directly related to the output of the stone powder grinding machine and the service life of the parts. The hardness of the grinding material can test the wear resistance of the stone powder mill to a certain extent.

2, the impact of material moisture content on the stone powder grinding machine

In the grinding process of stone powder mill, there will be a large number of stagnant finished products and unqualified fines on the material bed, if the moisture content of the material is too large, the new material will be combined with the fines, resulting in the formation of cake on the grinding disc. In the case of continuous feeding, the material layer of the grinding disc will keep thickening, resulting in the grinding rollers not being able to effectively crush and grind the material. Due to the excessive load, the grinding powder equipment will vibrate or stop running, and the water content of all materials can test the smoothness of the internal operation of the stone powder grinding machine to a certain extent.

Second, observe the operation of stone powder grinding machine

Under normal circumstances, the stable operation of the stone powder grinding machine can achieve low dust, low noise, stable operation of the stone powder grinding machine also has an important impact on the internal stone powder grinding machine, reduce stone powder grinding machine wear and energy consumption. However, these factors, such as the grindability of the material, feed speed, system airflow, grinding pressure, classifier speed, etc., will have an impact on the stability of the operation of the grinding equipment. Therefore, it is necessary to observe the operational stability of the grinding equipment to reduce unnecessary production consumption.

Third, observe the pressure resistance of stone powder grinding machine

According to the actual production situation, when the stone powder grinding mill is running for a long time, the production capacity of the stone powder grinding mill will decrease to a certain extent, which is mainly due to the wear and tear of the grinding rollers and grinding discs, which leads to changes in the grinding structure and grinding pressure in the grinding area of the stone powder grinding mill.

Therefore, during the site visit, we should learn about the service life of the wear-resistant parts of the grinding equipment, which have a long service life, low energy consumption, and relatively low project operating costs. By comparing the service life of different stone powder grinding mills, we can have a general understanding of the project operating cost.
