Efficient and stable operation
Efficient and Stable Operation

ZK SEPARATION is dedicated to creating high-quality and cost-effective products. We have high-quality modern processing equipment, which provides the fundamental assurance for producing top-notch separators in the processing workshop. The ZK high-efficiency disc stack centrifuge boasts an exceptional separation factor of up to 14,500G and can achieve efficient and stable operation, whether as a stand-alone machine or within a modular design.

High-Performance Stainless Steel Material

To ensure the stability and lifespan of the separator, considering the possibility of corrosive ions or substances in some separated materials, we opt for materials with high strength and excellent corrosion resistance. Examples include AISI 321, AISI 316, AISI 316L, and high-strength Cr-Ni-Mn stainless steel. We will make rational selections among these materials based on the characteristics of the substances to ensure the efficient operation of the separator.

The control system of ZK disc stack centrifuge is equipped with a fully automated cleaning program, capable of cleaning the external surfaces of the machine hood and the drum. This ensures that each mechanical cleaning is thoroughly carried out, avoiding any impact from human factors on the cleaning effectiveness. This cleaning system is highly suitable for the biopharmaceutical field, meeting the requirements of CIP/SIP, and complying with GMP regulations.

Working Principle of Disc Stack Centrifuge

Disc stack centrifuge is a kind of industrial centrifuge used to clarify and separate liquids. It also belongs to vertical centrifuge. Because there is a set of disc-shaped parts (discs) nested together in the drum named disc centrifuge. The drum is driven by a motor through a vertical shaft to rotate at a high speed. The material enters the disc centrifuge drum through the feed pipe, and then enters the disc group. It accelerates in the distribution chamber until synchronized with the speed of the drum. When the suspension (or emulsion) flows through the gap between the discs, the solid particles settle on the discs to form sediment under the action of centrifugal force. The sediment slides along the surface of the disc, then it separates from the disc and accumulates in the part of the drum with the largest diameter - solid slag collection chamber. The solid phase is discharged by controlling the sealing water and slag water, and the separated liquid is discharged from the liquid outlet. The function of the disc is to shorten the settlement distance of solid particles and expand the settlement area of the drum. The installation of the disc in the drum greatly increases the production capacity of the separator.
