WORKING PRINCIPLE inside the Hardinge BALL MILL. In the Hardinge Mills, due to the action of the cones, the coarse material on entering the machine gravitates to the point of largest diameter.Here it comes in contact with, and is broken by, the largest balls moving at the highest velocity and falling from the greatest height.
As a result, ABB developed three of the largest diameter and most powerful drive systems for a SAG and two ball mills installed at the highest altitude to date. The fully integrated and optimized solution for the grinding circuit consists of: 1 x 28 MW GMD to power the 40 ft SAG mill 2 x 22 MW GMDs to power two 28 ft ball mills
Oct 10, 2016 · The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
Nowadays more and more mills are fed by frequency converter systems, allowing for higher performance and flexibility of operation. ABB continuously extends technical and performance frontiers of ringgeared mill drive (RMD) technology to fit your site requirements.
Ball mills on the other hand, as far as process requirements are concerned, did not require variable speed. However, frequency converter based drive systems provide benefits that improve the ball mill operation. FIXED SPEED CONFIGURATIONS The key issue to operate a mill
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
