technical field

The utility model relates to a screening machine for single-layer multi-stage screening, which belongs to the field of screening machines.

Background technique

The process in which the broken material is divided into different particle sizes through one or several layers of sieve surface is called sieving. The screening machine is a vibrating screening mechanical equipment that uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divide sand, gravel, crushed stone and other materials into different grades according to the particle size. The screening process of the sieving machine is generally continuous. After the sieving raw materials are fed to the screening machine (referred to as the sieve), the material smaller than the sieve size passes through the sieve hole, which is called the under-sieve product; the material larger than the sieve size passes through the sieve. It is continuously discharged on the surface, which is called the on-sieve product. The existing screening machines for multi-stage separation usually adopt multi-layer structure screen surface for screening. Although the effect of multi-stage separation is achieved, due to the multi-layer structure, As a result, the screening machine occupies a larger area than the single-layer screening machine, and the cost is higher than that of the single-layer screening machine.
