高效能非金属矿物超微粉碎机及控制方法

By designing a high-efficiency non-metallic mineral ultrafine pulverizer, the continuous rotation of the main shaft and push plate, along with high-pressure airflow, enables continuous impact and cyclic pulverization of raw materials between the pulverizing zone and the return zone. This solves the problems of low efficiency and high energy consumption in traditional pulverizing technology and provides a more efficient solution for the production of non-metallic mineral ultrafine powders.

AI Technical Summary

Technical Problem

Traditional pulverization technology is inefficient, energy-intensive, and has unsatisfactory pulverization results, making it difficult to meet the demand for non-metallic mineral ultrafine powders with finer particle size, higher purity, and better performance.

Method used

Design a high-efficiency non-metallic mineral ultrafine pulverizer. The main shaft and push plate drive the raw material to flow continuously between the pulverizing zone and the return zone. Combined with a high-pressure airflow and negative pressure system, it realizes continuous impact pulverization and circulation of the raw material. The additional energy requirement is reduced by centrifugal force and gravity.

Benefits of technology

It improves crushing efficiency and speed, reduces energy consumption, and achieves efficient, economical, and flexible crushing of non-metallic minerals. It has a simple structure and is easy to process and maintain.

Abstract

本发明涉及粉碎设备的技术领域,特别是涉及高效能非金属矿物超微粉碎机及控制方法,包括括横筒,横筒轴线水平,横筒内沿横筒轴线方向设置有填充板,填充板将横筒内部空间分成左侧粉碎区、右侧返送区、上侧进料区和下侧的排料区,粉碎区竖直,返送区的形状为圆筒状,进料区朝向粉碎区方向向下倾斜,排料区朝向返送区方向向下倾斜;通过主轴和多个推动板的连续旋转,可使原料离心运动并在粉碎区和返送区之间连续流动,由于原料在粉碎区内实现撞击粉碎工作,因此利用该方式可连续、重复对原料进行撞击粉碎处理,并且由于原料在粉碎区内与粉碎区内壁发生往复反弹式撞击,原料之间同样发生撞击,因此可大大提高原料粉碎效果。
