This Outfeed Sump of the Ball Mill also has a requirement for measuring the Suspended Solids Density. The Pulp/Slurry is pumped to the inflow of Cyclones and it is very important to control the solids density inflow to the Cyclone.
rougher head feed is a combination of multiple ball mill hydrocyclone overflows and, therefore, does not represent the performance of any individual ball mill circuit. Thus, the rougher head stream samples cannot be used in a ball mill control strategy for real-time particle size control.
cyclone i Control strategy ... Grinding control strategy on the conventional milling circuit With the increase in ratio set point, a decrease in Cyclone 1 ... The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful.

control system will continue to evaluate downstream operational states, and any associated control actions will be implemented whenever a true result is achieved. For a ball mill circuit, several measurements are considered when defining the process states: • Power draw • Mass-flow to cyclone • Sump level • Mill discharge as % solids
Ball mill classification system optimization through functional performance modeling ... performance (Eq. 1), mill grinding performance, cyclone separation performance, and pump head and flow rate performance for the survey. ... through A/C Inverter for speed control
In this case, cyclone underflow is fed to a weired area in the underflow tub, and gravity-circuit feed taken from this area. Slurry excess to the capacity of the gravity circuit overflows back to ball-mill feed. For those circuits treating ball-mill discharge, a sluice can often be arranged to provide some preconcentration for the gravity circuit.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
RETSCH instruments are used in science and industry for the sample preparation for a wide range of different analytical methods as well as for particle size analysis in the context of production control and quality monitoring.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
PRIMARY BALL MILL CIRCUIT. A flowsheet of the primary ball mill circuit is shown in Figure 1, indicating . the various control loops and process measurements available to be utilized by an expert system. The circuit consists of two identical . primary ball mills running in parallel with an overall processing capacity of 2500 TPD.

Nowadays many concentrator adopts the following process: undressed ore belt feeder into the ball mill, grinding machine overflow their products to the slurry pool, then use glue pump during transport to the hydro-cyclone ...
Ball Mill and Grinding Circuit Preparation for Start-UP The following items must be checked before the equipment in the Grinding Circuit is started. Check the ore slot feeder for obstruction or hang—ups. Check the ball mill belt feeder for undue buildup of material. Check oil level in ball mill lube oil tanks. Also, check grease level in the mill ring gear spray lube drum.
The 5m x 6.7m grate discharge SAG mill could be converted to a 1,600,000 t/a ball mill in a future expansion. An existing ball mill and cyclone cluster were reloed from the Mount Isa Copper Concentrator for use in this plant. In addition to lead and zinc concentrates, a lead/zinc middlings product was recovered by flotation

Our expert control ball mill strategies automatically adjust sump water and mill water addition, mill speed where available and can open and close cyclones when appropriate. The strategy smooths disturbances and provides optimal particle size in cyclone overflow to flotation.
· Air moves under centrifugal action. Centrifugal force separates the particles. Air is moves like a cyclone and material are subject to drops by gravity. Air escapes through the top leaving particle dropped at bottom. Our cyclone separator is available with broad range of flow capacity with fully optimized models.
