In accordance with the field visit of working site and technical guidance, Fote Machinery introduced 3 stages crushing process for our customer.Details
1 Rod milling – a rod mill with a diameter of 244 meters inside new liners grinding wet in open circuit 2 Ball milling – a ball mill with a diameter of 244 meters inside new liners grinding wet in open circuitDetails
For temperature sensitive products ball mills can be fully jacketed to maintain temperatures of the product Ball mills scale up well and in fact improve in performed with increasing size Ball mills are available in sizes from laboratory scale also called milling jars of 01 usg to large 5000 gallon millsDetails
Planetary Ball Mill Use 304 Stainless Steel Ball Mill Jar 15L Applications Grade 304 is most widely used austenite steel also known as 188 for its composition of 18 chromium and 8 nickel 304 may be referred to as A2 stainless not to be confused with A2 grade steel also named Tool steel a steelDetails
Finally a cylindrical mill with a grid was used The grid was 1 foot from the feed end of a 2 by 3foot cylindrical mill Balls of 25 inches to 1 inch were placed in the feedend sections and 075inch balls in the discharge end The grinding was moderately better than without the gridDetails
A ball mill efficiently operated performs a wide variety of services In small milling plants where simplicity is most essential it is not economical to use more than single stage crushing because the SteelHead Ball or Rod Mill will take up to 2″ feed and grind it to the desired fineness In larger plants where several stages of coarse and fine crushing are used it is customary to crush from 12″ to asDetails
Ball Mills Steel Ball Mills Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s The basic construction of a ball mill is a cylindrical container with journals at its axisDetails
The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter Figure 811The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weightDetails
As a thumb rule powder to be milled should be taken as 25 of total ball weight If the quantity of charge is very less then milling balls will start to collide with each other and no milling willDetails
The ball mill 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 There are many types of grinding media suitable for use in a ball mill including ceramic balls flint pebbles and stainless steel ballsDetails
