Figure 4a is a cutout diagram of a largecapacity (200 hp) pellet mill. Although power transmission by means of a Vbelt drive is shown (1), gear drive coupling of motor to the main shaft (2) is also possible. Feed from a surge bin (3) is metered into the steam conditioning chamber by a .
Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is m diameter and m long with a corresponding motor power of 22 MW (Toromocho, private communications).

Aug 30, 2019· 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the .

Energy Saving Ball mill [ Capacity ]: –90 t/h [ Applicable Material ]: Ball mill is key equipment for grinding materials after crushing process. It is used to grind kinds of materials into fine powder 2075micrometer. Based on discharging type, It could be grate type,overflow type etc.
Ball Mill Design/Power Calculation. The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ''chunk size'', product size as P80 and maximum and finally ...
Ball mill should keep even feeding in operation; the even feeding means stable feeding quantity and same particle size distribution.. Unsuitable feeding would make the product size become bigger, and bring more return capacity, which cause "bloated" phenomenon for grid type ball also means overload of the ball mill.
