Raw mill

Raw mill is suitable for various ores and other materials metallurgy, mine, chemical and construction. Raw mill is mainly used to grind the raw materials into powder during the manufacture of cement. And then the powder will be fed into a kiln which transforms it into clinker. And then the clinker will be ground to make cement. A&C can provide high efficient raw mill for customers to make cement.

There are two kinds of raw mills wet raw mill and dry raw mill. Wet raw mill is more efficient while dry raw mill is energy-saving. The engineer will recommend the most suitable one for the customer according to their situations. Besides, it has two forms of milling, one is an open form, and the other is a recycle close form equipped with powder concentrator.

Working Principles

This ball mill is horizontal type and tubular running device, has two warehouses. This machine is grid type and its outside runs along gear. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device. In this warehouse, there is a ladder scaleboard or ripple scaleboard, and different specification steel balls are installed on the scaleboard, when the barrel body rotates and then produces centrifugal force, at this time, the steel ball is carried to a certain height and falls to make the material grinding and striking. After ground coarsely in the first warehouse, the material then enters into the second warehouse for regrinding with the steel ball and scaleboard.
