Aug 212020 3 Wet ball mill has a simple transportation device with less auxiliary equipmentso the investment is about 5%-10% lower than that of dry ball mill. 4 The grinding particle size is fine and uniformand the wet ball milling can not only grind agglomerate into fine particlesbut also mix the lean material and the plastic material well.
The ball mill is a key piece of equipment for grinding crushed materialsand it is widely used in production lines for powders such as cementsilicatesrefractory materialfertilizerglass ceramicsetc. as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials either wet or dry.
Keywords: Ball millsgrinding circuitprocess control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physicalmechanical and chemical characteristics. Typical examples are the various oresmineralslimestoneetc.
Conventional ball mills are usually limited to a particle size of 1 after one hour of grinding since gravity causes the particles to fall out of the grinding zone (between the media). Milling can be done either wet or dryalthough it is generally possible to get smaller particle
operating parameters. Mill speedmill chargeball sizeand wet grinding are the parameters which have been selected for the present study. It is hoped that the analysis of the data acquired will allow insight as to which parameters will require a functional form if they were to be integrated into a complete liberation model. 1.2

Ball Mill Simulation In Wet Grinding Using A Tumbling Mill A method for simulating the motion of balls in tumbling ball mill under wet condition is investigated. The simulation method is based on the three-dimensional discrete element method (DEM) and takes into account the effects of the presence of suspension i.e. drag force and buoyancy.
The operating principle of the ball mill consists of following steps. In a continuously operating ball millfeed material fed through the central hole one of the caps into the drum and moves therealongbeing exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Thendischarge of ground material performed
