What are the main aspects to see if the mill is good? A few tips to help you test the quality of the mill.
Seeing is believing, in the process of purchasing a mill, choosing to visit the nearby mill production plant is a good way to understand the performance of the mill. So what are the main aspects to see if the mill is good? What are the main observations of the mill during the field visit? The editor will give you tips to help you check the quality of the mill.
Observe The Influence Of The Input Material On The Mill
Incoming materials refer to the materials to be processed by the mill. From feeding to discharging, the entire processing process has a huge impact on the mill. Mainly include the following influences:
1. The Influence Of Material Hardness On The Mill
The hardness of the grinding material is usually characterized by the Mohs hardness (range 1-10), which differs depending on the type and content of inclusions in the original ore. Generally speaking, the material has high hardness, poor grindability, and high wear of the mill. Therefore, the hardness of the material is directly related to the product output and the service life of the wear parts of the mill. Observing the hardness of the grinding material can be used to investigate the grinding powder to a certain extent. The wear resistance of the machine.
2. The Influence Of Material Moisture Content On The Mill
During the milling process of the pulverizer, there will be a large number of finished products and unqualified fine powder on the material bed that have not been taken away by the airflow in time. If the water content of the raw material is too large, the new material will stick to the fine powder, causing the mill disc to stick. The formation of a cake, under the condition of continuous feeding, will cause the material layer of the grinding disc to continue to thicken, so that the grinding roller of the mill can not effectively crush and grind the material, and the mill will vibrate or stop due to excessive load. Under the condition that the water content meets the feeding regulations, observing the water content of the feeding material can investigate the smoothness of the internal operation of the mill to a certain extent.
Observe The Operational Stability Of The Mill
Under normal circumstances, the stable operation of the mill can achieve low dust and low noise, and the smooth operation also has an important impact on the interior of the mill, reducing the wear of the mill and reducing energy consumption. Factors such as material grindability, feed volume, system air volume, grinding pressure, and separator speed will all have an impact on the operational stability of the mill. Therefore, it is necessary to observe the operational stability of the mill to reduce unnecessary production consumption.
Observe The Compressive Ability Of The Mill
According to the actual production situation, when the pulverizer runs for a long time, the capacity of the pulverizer will decrease to a certain extent. The main reason is the wear of the grinding roller and the grinding disc, which leads to the grinding structure and grinding of the grinding area of the roller disc. The pressure has changed.
Therefore, when investigating the site, you should understand the service life of the wear parts of the grinding machine, the service life of the wear parts is long, the energy consumption is low, and the project operation cost is relatively low. Have a general understanding of operating costs.
