Benshaw has in excess of 100,000 HP of installed ball mill motor control base, and 30 years of experience with ball mill motor controls. Using this experience, Benshaw has pioneered the innovative technique of using a low voltage AC drive to power a medium voltage application providing a reliable, cost effective solution for ball mill control.
MILL CONTROL: BALL MILL CONTROL EXAMPLE Process Description The copper concentrator in Pinto Valley, Arizona processes a 0.4% 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.
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. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Sep 06, 2010 Control air purging, make their relationship, it can control the equilibrium of the grinding mill. 1.2 Difficult to control the ball milling . 1) from its existing mill run characteristics. Noise ...
Introduction. The ball mill is indispensable grinding equipment in the ore beneficiation process.How to control the ball mill noise? Ball mill is mainly used for grinding materials in the industrial production process. Due to the large volume and heavy tonnage, the noise ( strong vibration and noise ) generated is usually above 95dB(A), which is serious affects the physical and mental health ...
Dec 19, 2019 The ball mill lays a heat-resistant soft rubber mat between the inner surface of the ball mill drum and the liner. To prevent the soft rubber mat from overheating, a 10-15 mm thick industrial felt is placed between the ball mill liner and the soft rubber mat. The ball mill can Reduce the ball mill noise below the allowable standard.
The Millstar Advanced Control System has a comprehensive suite of control strategies that can be applied to provide an innovative control solution for almost any milling circuit configuration. The main goals are: • Stabilise the mill feed. • Control product quality to the downstream processes. • Optimise throughput and grinding efficiency.
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc ...
the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15%+ 300 µm. If the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence

Apr 01, 2005 Controlling the performance of a closed circuit ball mill is a challenging problem due to its complex dynamic characteristics and heavy interactions among the control loops.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill
The ball mill grinding device control system in accordance with the teachings of the present invention prevents overloading of the ball mill because the recycle rate is not allowed to become greater than desired, such that the ball mill is not permitted to choke and in effect it permits the ball mill
The ball mills were controlled through a Siemens HMI, compliant to CFR21 part 11. This allowed flexibility for the user, enabling them to control elements such as timers, positioning control,
