Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of zinc powder production equipment, especially to a ball mill for special-shaped zinc powder production. BACKGROUND

[0002] In the field of special-shaped zinc powder production, the traditional ball mill adopts a single-layer frame structure, and the core power components and material processing components are installed in a centralized manner, which is prone to power transmission interference and component layout disorder. The driving motor of the traditional equipment is directly connected with the grinding mechanism, and lacks a matching speed reduction adjusting component, which makes it difficult to accurately control the grinding speed. When the speed is too high, the zinc raw material is prone to excessive impact to produce fine powder, which does not meet the shape requirements of special-shaped zinc powder. When the speed is too low, it cannot provide sufficient grinding force, resulting in low production efficiency. At the same time, the traditional ball mill does not have a special cooling structure designed for the grinding characteristics of zinc powder. The high temperature generated by the friction of the material during the grinding process can cause the zinc powder to oxidize, which can damage the chemical stability of the product. High temperature can also cause the zinc powder to agglomerate, affecting subsequent processing and use. In addition, the sealing performance of the traditional equipment is poor, and the dust escapes seriously during grinding, which not only pollutes the working environment, but also causes waste of raw materials and increases production costs.

[0003] The existing ball mill for special-shaped zinc powder production has obvious defects in the design of the feeding and discharging system. Most of them use a single tank for raw material storage and finished product temporary storage, which causes mutual interference between raw material supply and finished product output, and is prone to material mixing and conveying blockage. The traditional feeding structure is mostly designed in a straight cylinder type. The raw material is prone to accumulate at the bottom of the tank during conveying, and frequent manual cleaning is required to ensure continuous feeding, which increases the labor intensity. At the same time, the traditional equipment lacks a special exhaust structure. A large amount of gas and dust mixture is generated in the grinding cavity during the grinding process. If it cannot be discharged in time, it will cause the pressure in the cavity to rise, which not only hinders the normal flow of the material, but also reduces the movement efficiency of the grinding medium, further affecting the grinding effect. In addition, the maintenance channel of the traditional ball mill is not designed perfectly. The double-layer structure equipment is not equipped with convenient auxiliary operating components. When the staff maintains and repairs the upper components, they need to use external climbing equipment, which has safety hazards and low maintenance efficiency, prolongs the downtime of the equipment, and affects the overall production progress.
