Horizontal screw centrifuge is a kind of horizontal screw unloading, the settlement of continuous operation equipment. This kind of centrifuge working principle is: the drum and spiral to a higher speed at a certain differential rotation, material introduced by feeding tube continuous feeding screw barrel, accelerated after the drum, under the action of centrifugal force field, the heavier solid deposit formed in the drum wall sediment layer. Transporting spiral will deposit solid content continuously pushed to drum cone, the slag discharge mouth closed. Lighter liquid phase content of inner liquid ring is formed, by continuous overflow drum drum big end the overflow mouth and the drainage discharge mouth closed. This function running at full speed, continuous feeding, separating, washing and discharge. With compact structure, continuous operation, stable running, strong adaptability, large capacity, easy maintenance, etc. Suitable for separation of solid phase particle size is greater than 0.005 mm, concentration range of 2-40% of the suspension. Widely used in chemical industry, light industry, pharmacy, food, environmental protection and other industries.

Horizontal screw centrifuge in environmental applications mainly refers to industrial and civil sewage treatment process of sludge dehydration. Today's environmental problems become the focus of common concern all over the world, in this context, the value of the horizontal screw centrifuge reflected, sewage plant or related plants in the settlement or the belt type filter press for sludge dewatering enrichment, test to prove: the sludge moisture content from 98% to 80%, its volume can be reduced 10 times, because of this, horizontal spiral sedimentation centrifuge due to its innate capacity big, automation, dehydration effect is good wait for a characteristic, has been widely used in the field of environmental protection and promotion. Horizontal screw centrifuge item sales accounted for about half of all centrifuge products, has established its irreplaceable position. Abroad, sewage treatment equipment preferred horizontal screw centrifuge.
