The range of Continuous Ball Milloffered by SBM find application in meeting the demands of the client. Further these are designed with both bolt and bolt-less liners that successfully suit specific process requirements. Our Continuous Ball Mill are offered manufactured from quality material.
Continuous ball mill are used wherein the finished product is obtained from a single pass through the mill. This type of operation produces a wide particle size distribution with a high proportion of superfines in the product.
Continuous ball mills require careful selection of length/diameter ratio of the mill to ensure correct residence time and product fineness. These are designed for continuous operations and produces a relatively coarse product with minimum generation of superfines.
Continuous Ball Mills
The grinding chamber is formed from perforated grinding plates bolted to shaft mounted end plates fitted with liners.
The chamber is totally surrounded by two concentric sets of perforated screens.
The chamber contains a steel ball charge.
Ground material passes through the perforated grinding plates onto the inner screen surface. Material then passes through this screen continuing to the outer screen which controls the final product size.
Oversize (or semi-ground) material retained on each screen is returned to the grinding chamber through a series of return plates.
Product is collected within a surrounding dust-tight casing with integrated discharge hopper.
