Working principle of two-stage piston pusher high-speed centrifuge

The two-stage piston pusher high-speed centrifuge is a specialized piece of equipment designed for the efficient separation of crystalline and fibrous materials. This advanced machine utilizes a dual-drum system, where two coaxial drums rotate at the same speed but operate independently in terms of movement. Each drum is equipped with a perforated structure and covered with a filter cloth to facilitate the filtration process. The first-stage drum has a smaller diameter compared to the second-stage drum and can move reciprocally relative to it. As the material is introduced into the first-stage drum via a feeding tube, it is evenly distributed across the rotating surface by a distributor. During this phase, most of the mother liquor passes through the filter cloth and exits the machine through a designated liquid discharge port. Once the initial filtration is complete, a piston pusher mechanism transfers the resulting filter cake from the first stage into the second drum. This ensures that the cake remains in the second drum for an extended period, allowing it to be subjected to higher centrifugal forces. As a result, the final product achieves a significantly reduced moisture content, making it ideal for applications requiring dry and compacted solids. After the second-stage filtration, the remaining filtrate is also discharged through the same liquid outlet. Meanwhile, the piston pusher then moves the fully processed filter cake out of the second drum and discharges it through a separate slag discharge port. This two-step process not only enhances the efficiency of the separation but also improves the quality of the final product. Overall, the two-stage piston pusher high-speed centrifuge offers a reliable and effective solution for industries dealing with challenging materials such as crystals and fibrous substances. Its design ensures optimal performance, minimal downtime, and consistent results. Http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn
