MILL CONTROL: BALL MILL CONTROL EXAMPLE Process Description The copper concentrator in Pinto Valley, Arizona processes a % grade copper ore from a nearby open pit mine. The unit operations consisting of crushing, grinding, and flotation process about 65,000 tons of ore per day in six overflow ball mills.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

the instrument. The continuous signal allows particle size to be used as a process variable for control purposes. A strategy was developed and implemented which allows for the production of a controlled grind size from the conventional circuit (ball mill 2)
Control stabilization for ball mills BrainWave stabilizes the operation of ball mills, resulting in improved particle size distribution and increased fines production. It is able to stabilize the particle size distribution by continuously adjusting the mill load, typically achieved by adjusting the secondary crusher mantle gap to regulate production rate for the crushing plant.

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 particlesize measurement device and sizecontrol cyclones.
Operation aim of ball mill grinding process is to control grinding particle size and circulation load to ball mill into their objective limits respectively, while guaranteeing producing safely and stably. The grinding process is essentially a multiinput multioutput system (MIMO) with large inertia, strong coupling and uncertainty characteristics.
Cement Plant Process and Instruments Used SlideShare. Oct 22, 2015 The Ball Mill contains 3chambers:Dry, coarse, fine. The material is fed to the ball mill in the inlet side and the hot gas from preheater outlet is also fed in the inlet of ball mill.

Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore, mineral dressing, preparing talc powders and many
RAW MILL 9. The Ball Mill contains 3chambers:Dry, coarse, fine. The material is fed to the ball mill in the inlet side and the hot gas from preheater outlet is also fed in the inlet of ball mill. The material is moved through all the 3chambers before giving it to silo.
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 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.
