A ball mill feeder is designed to hold and meter the materials into the ball mill. It ensures the consistent and proper feeding of the materials into the mill, which is critical to the grinding process. The feeder also helps to improve the efficiency and performance of the ball mill. What are gravimetric feeders?

Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between and kWh per ton of energy to reduce the particle size.
Ball mills tumble iron or steel balls with the ore The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel The ball mill is operated in closed circuit with a particle size measurement device and size control cyclones.
The conveyor is of a standard design, with spare parts that are interchangeable between all Select™ Ball Feeder sizes. Easy to operate and accurate. Changes in the mill process parameters require variations to the media feed rate. The Select™ Ball Feeder is easily adjustable and can be changed from the operator control desk. Feeder design
Rubber liners are used in ball mills while metal liners are used in autogenous (AG) and semiautogenous (SAG) mills. The design of the liner of a mill determines the movement of the media. ... Spout Feeder A spout feeder has a very simple design. They have a steel or rubber lined chute that feeds directly into the trunnion opening of the mill.
where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
The project cost and financial projections may vary project to project as per technology selection, nature of civil work, price of raw materials etc. Table of Contents ... establishment of fish feed mills and introduce concentrated feed in the state which will be locally available to
Type CHRK is designed for primary autogenous grinding, where the large feed opening requires a hydrostatic trunnion shoe bearing. Small and batch grinding mills, with a diameter of 700 mm and more, are available. These mills are of a special design and described on special request by all Ball Mill Manufacturers.
