Description

Two-stage sieving machine for ceramsite sand

Technical Field

The utility model relates to a divide the sieve equipment field, concretely relates to haydite sand two-stage screening machine.

Background

The process that the broken materials are divided into different particle sizes through one or more layers of screen surfaces is called screening, the screening machine utilizes the relative motion of the broken materials and the screen surfaces to lead partial particles to penetrate through screen holes, and divides the materials such as sand, gravel, broken stone and the like into vibrating screening mechanical equipment with different grades according to the particle sizes, the screening process of the screening machine is generally continuous, and the materials smaller than the size of the screen holes penetrate through the screen holes after the screening raw materials are fed onto the screening machine (called a screen for short), so that the materials are called undersize products; material larger than the mesh size is continuously discharged from the screening surface and is referred to as oversize product.

In the production process of haydite sand, the two-stage screening machine is a equipment commonly used, but can appear some problems when sieving the haydite sand with current two-stage screening machine, because the haydite sand surface of making generally can adhere to more dust, consequently when utilizing the two-stage screening machine to sieve the haydite sand, a large amount of dust can be gushed out to the discharge gate department of two-stage screening machine, this can seriously influence the environment of mill, work meeting workers' health can receive very big influence under such environment for a long time, when opening the screening machine and clearing up the screening machine, the inside dirt that also can be very of screening machine, be not convenient for clear up, even if set up the timely dust collection operation to the screening machine of dust extraction in addition, also easily inhale the dust absorption fan with a large amount of haydite sand, influence the life of dust absorption fan.
