In the world of mineral processing and mining, efficiency and precision are paramount. One of the most critical pieces of equipment used to achieve these goals is the spiral classifier. This article provides a comprehensive overview of what a spiral classifier is, how it functions, its applications, and the technical specifications that make it an indispensable tool in mining operations. We will delve into the key parameters of our high-performance spiral classifiers, presented through detailed lists and tables to help you understand their capabilities. Whether you are new to the industry or a seasoned professional, this guide will offer valuable insights into optimizing your mineral processing activities.

A cylindrical froth flotation cell is a highly engineered mineral-processing unit designed to separate valuable minerals from gangue through controlled aeration, agitation, and froth stabilization. Its cylindrical geometry improves air dispersion, enhances bubble–particle collision efficiency, and ensures uniform slurry circulation—ultimately increasing recovery rates and reducing operational losses.

A Sand Washing Machine is a critical piece of equipment widely used in mining, quarrying, and construction industries. It helps remove impurities such as silt, dust, and clay from sand and gravel, ensuring a cleaner and higher-quality final product. The principle is simple yet effective: through a combination of water flow, mechanical agitation, and screening, the machine separates unwanted materials from valuable sand.

A Spiral Sand Washer—also known as a screw sand washing machine—is a heavy-duty mineral processing equipment used to clean, classify, and dewater sand and gravel. Designed with a long helical blade rotating inside a water-filled tank, it separates impurities from sand through friction, sedimentation, and mechanical agitation.

​In May 2023, Miltech from Russia signed a contract with our company to purchase two 1860 dry mills, a classifier and dust removal equipment.
