ball mills. the ore from the crushing section is delivered to the fine ore bin placed at the head of the grinding section, from which it is fed, together with water, to one or more grinding units consisting of a ball mill or rod mill in circuit with a classifier. one such unit with a conical ball mill is shown in fig.
ball mills give a controlled final grind and produce flotation feed of a uniform size. ball mills tumble iron or steel balls with the ore. the balls are initially 5 10 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.
a ball mill is a key machine used to crush and grind materials successively, widely used in many industries, such as cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and non-ferrous metals beneficiation, and glass ceramics, etc.
tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. like ball mills, grinding steel balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material.
grinding - ball mills. ball mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. to achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
iron ore, slag, copper ore, silver ore, galena, etc. structure the ball mill is mainly composed of a feeder, a discharging port, a turning device, transmitting devices that include a reduction gear, a small transmitting gear, a motor, and the electric control.
