Introduction

During the paper making process, on one hand, mid density cleaner is used as desander, on the other hand, it is served as pulp cleaner.It mainly is used to remove all heavier impurities like old ironware, staples, cinder block, sand, broken glass and so on, resulting in reducing the ware and tare of following equipments, impurity the pulp and improve the quality of paper. Sand remover is a key member of solid control equipments of drilling fluid that efficiently handle the shale shake underflow. Its solid control capacity is 30~50% higher than desander,which can lead to high drilling speed with low cost.

Advantages

1.Significant energy saving.

2.A good diffuser chamber design.

3.Simple structure, small footprint, large capacity.

4.Easy to operate, clean and high efficiency, long life.

5.According to materials of different types of cast iron and stainless steel type.

Operating Principle

1.The machine is using the difference proportion between fibers and impurities to separate the impurities.

2.The sully will rotate at high speed after into the cleaners in tangential direction under pressure,due to the different centrifugal force,fibers and impurities will produce radial stratification.

3.A large proportion of heavy impurities left behind the wall.Under gravity downwardly along the wall into the lower cone. With the radius of rotation decreases, the slurry flow rate loss is compensated to ensure that the centrifugal force to be strengthened, so that the movement of heavy impurities to the tailings discharge port.Light impurities and fibers move to the central area of low pressure gradually during they are in downward movement.

4.They will rotational increase after reaching the bottom of the diffuser tube into the central chamber, the gas and other light impurities than fiber will move to the center , and then discharged after rising to the top.Fine pulp put the rotational kinetic energy into pressure energy and then output from the side wall.
