Apr 09, 2015· This type of mill is normally used as the first stage of a milling process to provide a reduced size feedstock for a further milling process. Fig 1 Cross sections of a rod mill and a bar mill. Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods.
Classification of Energy-saving Ball Mill: Energy-saving ball mill for grinding various ores and other materials, are widely used in mineral processing, building materials and chemical industry can be divided into dry and wet grinding. According to different ways of discharge can be divided into the two types---lattice type and overflow type.
Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.
Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry.
The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.

While there are several types of ball-mill on the market, particular attention will here be given to the diaphragm type (Peripheral Discharge Ball Mills ), as the open-trunnion type, especially the conical mill, has been thoroughly discussed here. There is a prevailing impression that the ball-mill is a recent development; however, ball-mills ...
Ball mill could wet grind and dry grind many kinds of minerals and grindable material, according to different ore discharge methods, there are grid type and overflow type ball mill. 1.Discharge port Reasonable discharge port design, de-ironing separator could be set according to clients's requirement.
Advantages of grate ball mill. 1. As the ball mill transmission adopts rolling bearing instead of sliding bearings, friction is greatly reduced with easy start-up and significant saving energy; 2. Its discharging end adopts cone design, which not only increased the volume, but also forcing grading of ball .

Several types of ball mill exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 litres for planetary ball mill, mixer mill or vibration ball mill to several 100 litres for horizontal rolling ball mills.
Overflow Versus Grate Discharge Ball Mills: An Experimental Investigation It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are preferred for .
PDF | Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance.

Types of Mills Ball Mill A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling balls.
of rotation respectively. K is a calibration constant that varies with the type of discharge. For overflow mills K = 7.98 and for grate mills K = 9.10. This difference is ascribed to the presence of a pool of sl urry that is present on the bottom of overflow-discharge mills but not to the same extent in grate-discharge mills.
