CLEANING MILLS Remove the top cover as described earlier. Jog the mill into a discharge position. (Discharge position is one with the discharge screen on the bottom of the mill.)

The ball mill slakers are much more expensive than paste or slurry slakers. They are available in sizes ranging from 1000lb/hr to 50 tons/hr. Figure 3 shows an attritor type vertical ball mill lime slaker. The ball mill slakers are equipped with an external classifier, which separates slurry from the oversized grit and impurities. The oversize ...

The concentrator flowsheet begins with three rod mills operating in parallel and in open circuit followed by three ball mills operating in parallel and in closed circuit with a bank of ten 10inch hydrocyclones As illustrated in Figure 3, rod mill discharge and ball mill discharge are combined in the same sump and pumped to the cyclones

AG/SAG mill feed, trommel screen undersize product (-5.00 +0.00 mm), ball mill discharge and cyclone feed, overflow and underflow have been conducted in order to characterize the particle size distribution in the products and to carry out mass balancing of grinding circuits.

Grate Discharge Ball Mills have shown 25% to 45% more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills. To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod mill ...

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges ...

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. Various classifiers, such as screens, spiral ...

The power draw estimate is based mostly on the Bond ball mill formula where the feed to the ball mill is the projected SAG mill discharge that has passed through a "phantom cyclone". In the absence of testwork, many values used in the JKSimMet model may be assumed based on other surveyed mines or on default values built into the model.

In an air swept ball mill having a grinding Sspace and a hollow discharge trunnion, a constant discharge chamber comprising an annular foramious grid spaced from the discharge end of said mill, a frusto-conical screen in said chamber having its base secured in the central opening of said annular grid and its smaller end connected to a ...

bins and delivered to the wet sizing screens. Screen oversize is returned to HPGR's feed, closing the circuit, and the undersize slurry flows to the mill sump from which it is pumped to classifying cyclones. Cyclone underflow gravitates to the ball mills, which discharge to the mill sump, closing the circuit. The ball mill discharge stream passes

Grate discharge heads for ball mills are completely assembled in the shop, with grates, clamp bars, pan liners, and center discharge liners in place. Depending upon available handling facilities, the head or shell can be lined separately in a repair bay, or after assembly of the mill proper in the trunnion bearings.

Media will be added to each ball mill to maintain the power draw as required using a dedicated ball mill ball charging kibbles and hoists. Combined undersize product from the SAG mill discharge screen and ball mill trommels will gravitate to the cyclone feed hopper where it will be diluted with process water.

In a typical grinding mill application, the grinding media eventually fractures and wears into a fine metallic powder because of the heavy re-circulating load in the mill. Energy is unnecessarily wasted to mill the milling media. As shown in Figure 3, the trunnion magnet is mounted at the ball mill discharge point to replace a trommel screen.

grinding lines used both types of screens and on line two we used only a trommel. I've got to explain this a little bit. This flowsheet is typical of lines 1 and 3. The SAG mill has a trommel on the discharge end of it. Oversize is returned to the mill by a bucket wheel and water jet. Trommel undersize was pumped to a vibrating screen where the
