A modular lining system based on a broad range of components, which enables mill operators to tailor linings for specific applications. Practical experience is the key to optimal design. Some liner designers have been delivering wear-rubber mill lining for more than 20 years. The speed of a ball mill is in measured in revolutions per minute (rpm) of its drum.To measure this, you need a stopwatch (preferably that rings!) and a thick felt pen. Mark a bold line lengthwise on the outside of the drum. Then start the loaded ball mill and allow it to reach its steady loaded speed. Then press the stopwatch timed for a minute, and count the number of times the bold line comes into view before the stopwatch rings.
The speed of rotation (rpm) of the loaded ball mill is critical to success:too slow, and the milling takes too long; while too fast, and the contents (balls, ore and water) slam against the wall, inhibiting milling.Now use trial-and-error to discover the critical speed at which the centrifugal force pins the balls against the inside of the drum - they cease to roll and no longer fall. For this, the ball mill should be fitted with a variable speed drive.
Ball Mill is an efficient tool for grinding many materials into fine powder. Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine. To use the Ball Mill, the material to be ground is loaded into the Neoprene barrel that contains grinding media.
As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours. Quite simply, the longer the Ball Mill runs, the finer the powder will be. Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the Ball Mill runs. Our Ball Mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals, and make Black Powder.sand washing equipment: http://www.ore-machine.com/sand-washer.html
