The cost of a ball mill conversion from overflow to grate discharge is ‘fairly’ affordable at 65000 for a 13′ x 15′ mill This is only for the discharge head grates and pulp filters rubber A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill

Ball mill grinding machine is a kind of horizontal drumtype grinding mill with external gear and double bins Materials goes evenly through quill shaft in feeding device into the first bin which has ladder lining or ripple lining with steel balls in different balls are taken to a certain height by centrifugal force from drum rotation and then fall

Fig2 Schematic of Super Orion ball mill SO Ball mills are giant drums that are filled to between 30 and 40 of their volume with freely moving grinding media – in this case balls The diameter of the balls is between one and several centimeters to suit the application – smaller pearls for fine grinding results and larger ones for coarser grinding tasks

【Ball mill working principle】 High energy ball milling is a type of powder grinding mill used to grind ores and other materials to 25 mesh or extremely fine powders mainly used in the mineral processing industry both in open or closed circuits Ball milling is a grinding method that reduces the product into a controlled final grind and a uniform size usually the manganese iron steel balls or ceramic are

Since balls have a greater surface area per unit weight than rods they are better suited for fine finishing The term ball mill is restricted to those having a length to diameter ratio of 15 to 1 and less Ball mills in which the length to diameter ratio is between 3 and 5 are designated tube mills

Ball mill is the key equipment for deep grinding of materials after primary crushing It is widely used in cement silicate products new building materials wearresistant materials fertilizers ferrous and nonferrous metal mineral processing and glass ceramics industries

I am working in a plant with single stage grinding using a ball mill we operate the mill power at around 1400KW the feed size is 20mm we use 78mm64mm steel balls the ball mill is in closed circuit with classification cyclones there are 3 cyclones and we operate 2 with a pressure of about 90KPa the Cyclone Overflow is around 95 microns

Mills usually operate in the range 65 82 of critical but values as high as 90 are sometimes used A crucial parameter that defines the performance of a mill is the energy consumption The power supplied to the mill is used primarily to lift the load medium and charge

Peripheral Discharge Ball Mills Theory and Practice Previous Next The argument has often been advanced that fine material cannot be produced by impact alone and that fine grinding is done entirely by attrition or rubbing of adjoining balls It is only necessary to break up a few small pieces of rock on an anvil with a hammer to prove that

HGM Ultrafine grinding mill machine is used for grinding the barite limestone kaolin ceramics and slag etc with the hardness below scale 73 of Mohs and 280odd sorts of noninflammable and nonexplosive stuff in the trades of mining metallurgical industry chemical engineering and building material for high fine powder generating and processing

Description The principles of grinding are well established the preground liquor is pumped through the ball mill’s grinding vessel in one or more stages The refining action is accomplished by a special shaft with agitator arms and diverters rotating in a vertical jacketed grinding tank which is filled with hardened steel balls The various layers of grinding elements move in the same
