How to distinguish the quality of an ore mill?
It is best to visit the production site when buying an ore mill, so as to have a comprehensive understanding of its performance. So, how can you tell if a mill is good or not? During the on-site inspection, the focus was on the particle size, hardness and moisture content of the materials entering the mill, followed by the stability and the compressive strength.
First, the impact of abrasive materials on the performance of stone crushers
Ground material refers to material that has been pulverized by rocks. The whole process from material feeding to material discharging greatly affects the effect of stone grinding. Its main functions are:
1.Influence of material hardness on grinding effect in stone powder grinding
Because the ore contains a large amount of inclusions, its Mohs hardness (1-10) is related to the type and content of the inclusions in the ore. Generally speaking, the higher the hardness of the inclusions, the greater the difficulty of grinding , Therefore, the hardness of the raw material has a great relationship with the grinding efficiency and the life of the parts. The wear resistance of the sand crusher can be tested by the hardness of the material being ground.
2.The influence of the moisture content of the material on the performance of the stone crusher
During the grinding process of the stone crusher, due to the high moisture content of the raw materials, the newly added raw materials will stick to the fine powder, thus forming a mud cake on the grinding disc. During continuous feeding, the material layer on the grinding disc will become thicker and thicker, so that the grinding rollers cannot crush and grind the raw materials efficiently. When the load is too large, the milling device will vibrate or even stop, and the moisture content of various materials will have some influence on the smoothness of the internal operation of the milling machine.
Two,The working status of the ore pulverizer
Under normal conditions, stone grinding can achieve stable work with low dust and low noise, and has a significant impact on its internal structure, thereby reducing the loss of abrasive tools and reducing energy consumption. The grindability of raw materials, feed rate, system air flow, crushing pressure, classifier speed, etc. will all affect the working stability of the mill. Therefore, in order to reduce unnecessary production energy consumption, it is necessary to monitor the operation of the mill.
Three,Observation on the anti-extrusion performance of ore pulverizer
It can be seen from the production practice that with the long-term operation of the stone powder mill, the output of the stone powder mill will decrease to varying degrees. Change.
Therefore, when conducting on-site inspections, we need to have a general understanding of the service life of the wear-resistant components of the grinding equipment, because these components have a longer service life, and can also reduce energy consumption, thereby reducing project operating costs . By comparing the service life of different types of stone mills, we can intuitively understand the operating costs of the project.
