For primary grinding, the ratio could vary between 11and 1.81. For fine regrinding in open circuit, the ratio ranges from 1.31 to 1.51. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball
Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.
grinding circuit which in turn results in stable operation with optimum production capacity and energy efficiency. This research broadly aims to develop dynamic models based on energy, mass and size balance for simulation of open circuit wet ball mills under MATLAB environment. It integrates the energy balance with the
Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100 years. They are proven workhorses, with discharge mesh sizes from 40M to 200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.
Feb 16, 2009 Batch wet grinding of zeolite was studied with emphasis on a kinetic study in a laboratory size steel ball mill of 200 mm diameter. The breakage parameters were determined by using the single sized feed fractions of 850 600 m, 600 425 m and 425 300 m for the zeolite samples.The S i specific rate of breakage and B i,j primary breakage distribution values were ...
