SMALL C. I. W. BALL MILL. The CIW is a Small Ball Mill that's belt driven, rigid bearing, wet grinding, trunnion or grate discharge type mill with friction clutch pulley and welded steel shell. The 7 and 8 foot diameter mills are of flange ring construction with cut gears while all other sizes have cast tooth gears.

Please be aware that adding a grate to your ball mill will reduce your EGL by around 500 - 600mm (the depth of the pulp lifters and grate plate / liner thickness, plus it will also increase your mill motor power draw by anything from 10-20% for the same throughput. ... 100 to 160 micron range, fitting a grate discharge needs to be carefully ...

Due to the difference of ore discharge modes between the two mills, the productivity of grate ball mill is 10%–25% higher than that of overflow ball mill. When two-stage grinding is required, the first stage uses grate ball mill and the second stage uses overflow ball mill. When regrinding of coarse concentrate is required, overflow ball mill ...

Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. …

The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TC Series …

For our purposes, the experimental data on continuous grinding of limestone, feldspar, and quartz in a 40.6 cm long by 40. 6 cm diameter grate-discharge ball mill was found suitable. The feed rate of the solids, the weight percent of solids in the slurry, and the feed size distribution were the only operating variables covered.

The grate ball mill uses a low-level forced ore discharge. The ore slurry stored in the mill is less, and the minerals with high density are not easy to concentrate …

A set of experimental test work has been carried out in a continuous pilot ball mill of 0.41m X 0.56 m (diameter X length) at different mill speeds, percent solids and discharge mechanism. The results of study on material flow through a grate discharge tumbling mill verses an overflow tumbling mill are presented to emphasize the effect of ...

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to …

After the mill there would be a screen with 1mm opening, fines to spirals, coarse back to the mill. I used rod mills for such a coarse grind, but the handling of the rods is not as easy as if you use balls. So the question came up what a grate discharge ball mill would do here. I never used one.

Comchambered with the design of Φ 3.5 × 13m three-chamber ball mill, the design process of ball mill is described in detail. General arrangement of the mill Filling rate of grinding body in each ...

The grate plate is not installed on the discharge side of the overflow ball mill, but on the inner surface of the hollow journal bushing at the discharge end, the spiral blade with the spiral ...

Furthermore, it should be observed that a grate discharge ball mill converts about 20% more energy than an overflow discharge mill with the same shell dimensions. Ball mill shells are often furnished with …

By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the ...

Batch mills. Grate discharge mills. Trunnion overflow mills. Air-swept mills. The principles of these mills are illustrated in Fig. 1.4 and Fig. 1.5. Batch Mill. As the name implies, in the batch mills, Fig. 1.4a, the charge of powder to be ground is loaded into the mill in a batch and, after the grinding process is completed, is removed in a ...

Grate discharge ball mill is a traditional ball mill with forced discharge method by grate lining plate. The grate plate is installed at the ball mill discharging end. Materials with qualified size enter the fan-shaped chamber (composed of ribs and dustpan-shaped liner) through the small holes on the grate lining plate and then rise to the ...

Ball mills are usually either of the grate (diaphragm) or overflow type. Ball Mill Components. Ball mills consist of the following components: Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge – reduced feed exits the mill through the discharge. Ball Mill Components

Grate ball mill (Fig. 3), the discharge end of the mill is set with a grate. Peripheral discharge ball mill, and the products are discharged through the discharge port around the cylinder. According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill ...

It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are …

1. Overflow type: discharge ore through the hollow shaft. When the ore discharge surface is higher than the slurry surface, the finished product is discharged and the ore is automatically discharged by gravity, thus the overflow ball mill saves energy. 2. Grate discharge ball mill: the ore is discharged through the grate plate.

Objectives. At the end of this lesson students should be able to: Explain the grinding process. Distinguish between crushing and grinding. Compare and contrast different type of equipment and their components used for grinding. Identify key variables for process control. Design features of grinding equipment (SAG, BALL and ROD MILLS)

The role of the pulp lifters is to lift the slurry which passes through the grate into the discharge trunnion. They are incorporated in both flat- and conical-ended mills (Fig. 1) and are normally either radial or spiral in design (Fig. 2). Of the above two designs, the radial or straight type is most commonly used in industry.

Here we consider an overflow ball mill with feed and discharge of slurry as well as resident slurry included. This is modelled using the fully coupled DEM+SPH method. ... both with overflow and grate discharge. An industrial ball mill was then laser scanned and surveyed, including measurements of residence time distribution. Simulations using ...
