Background

Particle size screening in the laboratory can be largely divided into manual screening and mechanical screening. The manual screening can be divided into a dry screening and a wet screening, the dry screening is mainly applied to coarse grain screening, and the manual wet screening is often used for screening some micro-fine grain grades, so that the labor intensity is high, the micro-fine grains are easy to agglomerate, and the screening efficiency is very low. The mechanical screening is mainly characterized in that a motor drives a screen body to vibrate, fine materials are screened through under the action of mechanical force, due to the fact that the dry screening is adopted, the mechanical vibration strength is not enough, fine particles are difficult to screen through, and the screening result is greatly different from the actual result.

Traditional laboratory screening equipment mainly screens coarse grains, and for some finer particles, especially for screening of fine grain fractions below 1mm, wet screening is mainly carried out manually, conventional screening equipment is low in screening efficiency, and when screening is carried out in water or alcohol, fine particles are easy to agglomerate, and fine particles are difficult to penetrate through the screen.
