Description

Double-sieve-box screening machine

Technical Field

The invention relates to the technical field of screening machines, in particular to a double-screen box screening machine.

Background

The process of dividing the material to be crushed into different size fractions by one or more layers of screening surface is called screening. The sieving machine is a vibrating sieving mechanical device which utilizes the relative movement of bulk materials and a sieve surface to lead partial particles to penetrate through sieve pores and divide materials such as sand, gravel, broken stone and the like into different grades according to the particle size. The screening process of the screening machine is generally continuous, after screening raw materials are fed onto a screening machine (called a screen for short), materials smaller than the size of the screen hole penetrate through the screen hole and are called undersize products, materials larger than the size of the screen hole are continuously discharged from the screen surface and are called oversize products, and the screening machine is widely applied to the fields of mining industry, chemical industry, food and the like.

Present screening machine sieves with the mode of vibration through single sieve case more, and screening efficiency is lower, and the material is difficult to sieve thoroughly, is difficult to satisfy screening work demand, and present screening machine is finishing the back to the material screening in addition, and the material is difficult to convenient particle size according to after the screening to fall into different grades classification and accomodate, and is inconvenient to use.
