Mills to grind ore and non-metallic materials.jpg)
The process of fine grinding of ore materials and non-metallic materials in traditionally applied ball grinders and rod mills is char-acterized by high materials consumption and power-consuming. The grinded product obtained in these mills is characterized by a wide grain composition while its particles have a gravel shape which re-duces physicochemical activity of the finished product. Impact-centrifugal mode of grinding which is realized in SPA “Center” mills (grinding complexes) is considerably devoid of these draw-backs. Classifiers which are a part of the mills serve to withdraw the material of a required size from the zone of grinding and to return the underground product for re-crushing.
Such a layout permits cost-effectiveness of grinding and quali-tative indices of obtained product to be significantly improved. The end-product size can be regulated in operation without shutting down the equipment.
The material obtained through SPA “Center” mills is distinguished for a narrow granulometric composition, a low content both coarse and fine fractions. Particles possess a uniform isometric shape with a well developed surface. It contributes to the obtaining of durable and qualitative goods at the re-duction of material costs (binders, water) and power inputs.
Depending on the properties of materials, feed size and product size, productivity, requirements for mass and overall dimensions the mills can be of three design versions:
- with a built-in classifier;
- with a singly standing classifier;
- with a built-in and singly standing.
Basing on centrifugal mills SPA “Center” specialists developed different types of grinding complexes (КИ) representing a modular system of appliances (mills, fans, cyclones, filters, systems of automation and control) which are arranged and integrated in the most optimal way to secure high operational indices, sim-plicity and convenience in servicing, small occupied space and low power intensity.
