In mining, mineral processing, sand production and other industries, material classification is a critical production process. As a mature and reliable screening and classifying equipment, spiral classifier is widely used in production lines for its simple structure, stable performance and practical operation.
Spiral classifier realizes classification based on the difference in settling velocity of solid particles with different sizes and specific gravity in liquid. Coarse particles settle quickly to the bottom of the tank and are pushed by the spiral blades to return to the mill for re-grinding; fine particles are discharged with the overflow, achieving accurate separation of coarse and fine materials.
It can work with ball mills to form a closed-circuit grinding system for pre-classification and check classification, and also be applied in washing, desliming, dewatering and other working conditions.
The spiral classifier has a simple structure, mainly consisting of a tank, spiral body, transmission device and lifting mechanism. It is easy to install, adjust and operate, with stable continuous operation and low failure rate, effectively reducing maintenance downtime.
According to structure and application scenarios, it can be divided into high-weir type and submerged type, with single or double spiral options. High-weir type is suitable for coarse particle classification, while submerged type is more ideal for fine particle classification, meeting different production requirements.
Key components are made of wear-resistant materials to prolong service life and reduce maintenance costs. The equipment features moderate energy consumption and low noise, complying with industrial energy-saving and environmental protection standards.
With practical design and stable performance, spiral classifier serves as a reliable classifying equipment for mineral processing, sand production and non-metallic ore processing, providing stable and efficient support for industrial production.
