Specific Wear rate, Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 7080% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
Ball Mill Grinding Media Wear Rate. Coal Mill Grinding Media Wear Rate. We are a largescale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment.
#0183;#32;Re: how to estimate the wear rate for Ball mill. Dear Mr. Pankaj, Thanks for finding my work on Grinding ball pattern software useful. I have developed few software for cement industry which are listed below. I would like to inform you that these software are
#0183;#32;Raw mills usually operate at 7274% critical speed and cement mills at 7476%. Calculation of the Critical Mill Speed: G: weight of a grinding ball in kg. w: Angular velocity of the mill tube in radial/second. w = 2**(n/60) Di: inside mill diameter in meter (effective mill diameter). n: Revolution per minute in rpm.

Oleg D. Neikov, in Handbook of NonFerrous Metal Powders, 2009. Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary

Ball Mill Wear Rate the wear rate measured in gram per ton of cement produced is much higher for a ball mill than for a vertical roller millowever, the unit cost for wear parts for a ball mill is much lower than for a vertical roller millor a ball mill grinding opc to a fineness of 3200 to 3600 cm 2 g blaine the cost of wear parts ball, liners and mill.
Ball mills and vertical roller mills are used for many grinding applications in cement production: raw meal grinding, coal and pet coke, and finish cement grinding. Improving the competences of the team plays a key role in the optimal utilisation of the grinding installation in your cement plant.
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
