A pulverizer in general terms called as a grinder. In some countries, it is referred to as the atta chakki machine. It is a mechanical device that is used for grinding different types of materials. It has a lot of industrial uses, and it has made a lot of things easier. The use of pulverizers has contributed a lot to many industries as it is has increased production. In this article, we will see in detail the different kinds of pulverizers.
Ball and tube mills
A ball mill pulverizer is the one that has a horizontal rotating cylinder. It consists of a charge of tumbling. It might also have steel balls, rods or pebbles. When it comes to tube mill, it is revolving cylinder that is used for the pulverization of the ore, rock and many other hard materials. The material that needs to be pulverized is mixed with water, and it is fed into the chamber, and it comes out as slurry. In both ball and tube mills, the loners protect the cylindrical structure. But the balls undergo wear and tear and hence they need to be replaced when it is required. Regular checks and ball replacement will help in better performance of the machines.
Ring and Ball mill
This is the kind of mill that has two kinds of rings. Both the rings are separate from each other, and they are separated by large ball bearings. There are springs and adjuster assemblies in the mill. The material that has to be pulverized is loaded in the center or on the side. The air flow in the pulverizer carries out the pulverized material. The size of the pulverized material totally depends on the classifier separator. If the coal or any other material for that matter is light enough to be picked by the air, it goes to the classifier.
Vertical spindle roller mill
It is very similar to the ring and ball mill. This mill uses large tires to pulverize the coals. Most of the utility plants use this pulverizer. There is a central feed pipe in which the raw coal is fed. The material then reaches the grinding table. Then it is subjected to hot air that dries that material so that you will get fine products at the end. After this, the grinding process starts.
An attrition mill is a machine that is used to reduce the size of the solid particles. In ten hours, milling, 40 and 25 m2/g were obtained for alumina and barite. These are generally used in heavy industries that subjects different kinds of materials to size reduction. There will be a considerable difference after subjecting different materials to this particular pulverizer. The characteristics of the attrition pulverizer are very the same as the radial flow turbine mixer. The difference depends on the size and density of the particular material.
