Introduction to ultrafine ball mill

Ultra fine powder ball mill is a commonly used ball mill in mineral processing production. After rough crushing, the material enters the ultrafine ball mill through the lifting and conveying equipment. The grinding medium in the mill uses the energy obtained by the rotation of the mill to impact and grind the material. The crushed material enters the self separating micro powder classifier through the discharge bin for classification, achieving the separation of coarse and fine powders. Qualified fine powders are collected by the collector, and coarse particles are re entered into the ball mill for grinding from the lower end of the classifier. The purified gas is discharged by the induced draft fan. Ultra fine ball mill is a device for grinding lightweight and wet materials, which can achieve ultra-fine powder processing (up to 1250 mesh) without being affected by the light weight of the material. It can be used for both wet and dry grinding, and has a wide range of applications.

Structural characteristics of ultrafine ball mill

Our Jihong Machinery has redesigned the internal structure of the ultrafine ball mill to meet the needs of various industries for ultrafine grinding. This not only significantly improves the fineness of material grinding, but also significantly reduces the energy consumption of the equipment, achieving the goal of energy conservation and consumption reduction. When installed with a simple structure, it can be hung on the foundation plane at once. The ultrafine ball mill is composed of main components such as transmission device, rotary device, feeding device, discharging device, etc. The cylinder is embedded with wear-resistant lining plates for easy replacement, optimizing the shape and material of the lining plates and grinding steel ball media. The lining plates made of high-strength materials have good wear resistance and low maintenance costs. The machine runs smoothly, works safely and reliably, and has a low failure rate. The main bearing adopts a new type of high-precision, wear-resistant, and high-temperature resistant double row roller bearing in China, which can reduce energy consumption by more than 30% compared to ordinary ball mills. The discharge device adopts easy flow control for discharge, which can increase the grinding particle size yield by more than 15-20%.

Working principle of ultrafine ball mill

Ultra fine ball mill is also a type of ball mill, which is similar in structure and working principle to other ball mill equipment. Understanding the working principle of ultrafine ball mills is helpful for troubleshooting, maintenance, and upkeep in daily production. Therefore, we require every operator to be familiar with the working principle of ultrafine ball mills and be able to promptly detect faults in ultrafine ball mills during daily production, and provide targeted solutions.
During the operation of the ultrafine ball mill, large pieces of material need to go through first or even second crushing. The material is then fed into the first grinding chamber of the ultrafine ball mill by the feeding device through the feeding device. The hollow shaft spiral continuously and uniformly enters the first grinding chamber of the ultrafine ball mill. The grinding chamber is equipped with stepped or corrugated lining plates, and different specifications of grinding steel balls are filled in according to a certain proportion. The transmission device drives the cylinder to rotate, generating centrifugal force. The steel balls are then brought to a certain height by the lining plate and freely fall down, producing heavy impact and grinding effects with the material. This process requires a certain amount of time for continuous impact grinding. After the material reaches coarse grinding in the first grinding bin, the material with qualified fineness enters the second fine grinding bin through a single-layer partition plate. The flat lining plate and fine grinding steel balls in the fine grinding bin further grind the material. The final qualified powder material is discharged through the discharge grate, completing the ultrafine grinding operation.
