Small-quality powder electric grinding machine

Abstract

A small-quality powder electric grinding machine comprises a base, a material carrying platform, a mortar body, a lifting grinding mechanism and a supporting frame which are connected in sequence from bottom to top, wherein the supporting frame is used for supporting the lifting grinding mechanism. The lifting grinding mechanism comprises a telescopic unit, a grinding motor, a coupler, a counterweight disc and a grinding piece which are connected sequentially from top to bottom. The telescopic unit is vertically fixed to the supporting frame. The lower end face of the grinding piece is opposite to the upper end face of the mortar body, and the lower end face of the grinding piece and the upper end face of the mortar body are both in an arc shape. The small-quality powder electric grinding machine has the advantages that through the combined design of the lifting grinding mechanism with the mortar body and a worktable structure, materials can be ground automatically, efficiency is high, the grinding quality and the grinding particle size further can be selected according to the requirements, the structure is simple, operation is convenient, and practicability is high; and through the structural design of an S-shaped boss and the concave face on the grinding piece, the purpose of smashing is achieved, the grinding efficiency is improved, and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of laboratory small-quantity powder particle sample grinding treatment, in particular to a small-quantity powder electric grinder. Background technique [0002] During the test, it is often encountered that the sample needs to be ground before the next step of processing. Grinding specifically refers to the relative movement of the sample under a certain pressure through the grinding tool, so that the surface of the sample is finished or the solid particles are crushed; [0003] Mortar is a common tool for crushing small quantities of materials in chemical laboratories, chemical laboratories, and pharmaceutical factories. It is often made of ceramics, glass, metal, agate, alumina and other materials, and is equipped with pestle; pestle and mortar The relative movement between the walls of the bowl can be used for crushing and mixing of solid samples. [0004] The mortar has the advantages of simple structu...

Problems solved by technology

However, this type of mortar is purely manual in use, the grinding contact area is small, and there are disadvantages such as low work efficiency, poor grinding effect and high labor intensity.

Although there are various types of crushing and grinding mechanical devices on the market, most of them are designed for coarse materials or large-scale crushing, and there are few mechanical devices that can finely grind small amounts of solid abrasives that are common in laboratories.
