Equipment Overview
Sea salt often contains impurities and excess water after natural crystallization, requiring further refinement to meet quality standards for food, industrial, or pharmaceutical applications. The pusher centrifuge is a highly efficient, continuously operating separation device widely used in sea salt refining. It rapidly separates solids and liquids from the salt slurry through high-speed rotation, and a screw pusher continuously pushes the crystallized salt out, achieving continuous dehydration, washing, and discharge. Compared to traditional batch-type equipment, the pusher centrifuge offers significant advantages, including high throughput, stable operation, and a high degree of automation.
Working Principle
The pusher centrifuge consists of a rotating drum, main shaft, differential, and spiral blades. Sea salt slurry enters the rotating screen basket through the feed system. Centrifugal force forces the liquid phase through the filter and out, while the solid phase remains in the screen basket. The spiral, controlled by the differential, then slowly advances at a constant speed, pushing the separated salt crystals toward the outlet. The equipment can be equipped with a spray system for in-line washing of the sea salt, further removing impurities and impurities such as calcium and magnesium, thereby improving the purity of the refined salt.
Application Features
The pusher centrifuge is suitable for the continuous separation of a variety of crystalline salt products, particularly the following:
Food-grade sea salt: Requires high purity and moisture content, requiring meticulous washing and stable dehydration;
Industrial salt: Requires high separation efficiency and production capacity, and the pusher centrifuge can significantly improve overall process efficiency;
Pharmaceutical-grade salt: Requires a high-purity washing system and a clean-cut design to ensure product compliance with GMP requirements.
In addition, the device can adjust the filter mesh diameter, screw lead, and differential speed ratio based on material characteristics, flexibly adapting to different crystal morphologies and particle size distributions.
Sea salt refining is a complex process integrating separation, washing, and drying. The introduction of pusher centrifuges has significantly improved process efficiency and product quality, particularly in terms of high load capacity, refined control, and environmental protection and energy conservation. Our pusher centrifuges have been proven in the market for a long time, offering stable performance and support for customized design and complete system integration. Suitable for refined salt projects of all sizes, they are the preferred equipment for modern salt production enterprises on their path toward automation and intelligentization.
