What is the significance of the working speed of the grinding machine in production?

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 grinding medium and the lining plate can appropriately increase the rotation speed of the grinding machine to improve the productivity of the grinding machine, but it is not necessary to unilaterally pursue 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.

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 amount of wear is greatly increased. As a result, most concentrators use working speeds instead of critical reversing operations.

Making cabinet components is one of xuanlin CNC`s most popular applications. Our series of CNC Routers has made the manufacturing of doors, countertops, shelves, drawers and drawer fronts available to small, mid-size and large shops alike. Utilizing Xuanlin Cnc Routers, cabinetmakers have been able to both increase production and cut costs by reducing material handling and increasing throughput.
