AI Technical Summary

Technical Problem

Among existing pesticide production equipment, centrifugal pulverizers have high energy consumption and are difficult to achieve fine particle size, while ball mills have low energy utilization, are independent equipment, occupy a large area, and have problems with raw material transfer loss and pollution.

Method used

A raw material crushing device for pesticide production was designed. The device switches between centrifugal crushing and ball milling modes by swinging the outer cylinder. It uses the centrifugal force of the throwing cylinder for initial crushing and then uses grinding media for fine grinding to achieve graded crushing. The integrated device reduces the footprint and transfer losses of the equipment.

Benefits of technology

It effectively reduces overall energy consumption, improves crushing efficiency and product quality stability, and avoids the problems of insufficient crushing of coarse particles and excessive grinding of fine particles.

Abstract

The application discloses a raw material smashing device and method for insecticide production, and belongs to the field of grinding devices.The device comprises a workbench, an outer cylinder is installed on the workbench, an inner cylinder is arranged in the outer cylinder, a mounting column is fixedly connected in the inner cylinder, a feeding cylinder is axially and slidably connected to the middle part of the mounting column, a material throwing cylinder is coaxially and rotatably connected to the feeding side of the feeding cylinder, a conical surface is arranged in the feeding cylinder and the material throwing cylinder, and grinding media are placed in the inner cylinder; the method comprises the following steps: firstly, centrifugal smashing is performed on raw materials, and then ball milling is performed on the raw materials; the centrifugal smashing and the ball milling mode are switched by swinging the outer cylinder; the centrifugal force of the material throwing cylinder is utilized to make the raw materials collide with the inner wall of the inner cylinder to complete preliminary crushing; and then the grinding media are utilized to perform fine grinding in a horizontal state, so that classified smashing is realized, the problems that coarse particles are difficult to crush and fine particles are excessively ground in the traditional process are avoided, and the overall energy consumption is effectively reduced.
