Appropriately increasing the speed of the mill can increase the productivity of the mill but it is not a one-sided pursuit of high-speed grinding. Because of the increase in speed, there will be some problems. For example, today's ball mills are designed and manufactured at a lower critical speed. If you use critical speed or supercritical speed, the mill will lose its grinding effect due to centrifugation. Second, it will run at high speed. The mechanical vibration and component wear are aggravated, and the service life of the equipment is greatly reduced. At the same time, the internal grinding action of the ball mill is destroyed, the ore discharge becomes thicker, and the load of the classifier is increased, so that the product does not meet the requirements for qualified grain size. Moreover, the wear of grinding media and liners is greatly increased. Therefore, most of the beneficiation plant used in the production of critical operating speed without reloading operation.
The small Loader is a kind of earthwork construction machinery widely used in construction projects such as roads, railways, hydropower, construction, ports, mines, etc. It is mainly used
Small loader
Small loader
It is used for loading and unloading bulk materials such as soil, sand, lime, coal, etc. It can also be used for light shoveling and digging operations on ore and hard soil. Different auxiliary working devices can also be used for bulldozing, lifting and other materials such as wood loading and unloading operations. In the construction of roads, especially high-grade highways, small loaders are used for filling and excavating roadbed works, asphalt mixtures and aggregate and loading of cement concrete yards. In addition, it can also carry out operations such as pushing and transporting the soil, leveling the ground, and towing other machinery. Because the small loader has the advantages of fast working speed, high efficiency, good maneuverability, and light operation, it has become one of the main types of earth and stone construction in engineering construction.
