Trommel screens Trommels are wet screens that rotate in a similar fashion to ball mills on trunnions, where feed enters one end, and oversize discharges out the other end, with screen undersize discharging along the …
The project goal is to supply vibrating screens to withstand the sag mill discharge of 6000t/hr plus 4000m3/hr of water. This model is around 5.5m wide, 10.5m long and 6.5m high.
Our robust autogenous and semi-autogenous mills ensure efficient self-comminution of the product within the mill. In many cases, a SAM mill can replace a high-maintenance combination of crushing and screening equipment, making it a reliable, cost-effective alternative. As with ball mills, the material inside is lifted by the rotary motion ...
Rubber screens have for years proven to be very effective in combating wear. Generally our rubber screens out wear wire cloth 15 times longer. In addition to the superior wear-life, rubber screens substantially reduce noise levels. Compared to perforated steel plate, noise level reductions of up to 500% are common. Contact Our Experts.
The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product.. Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 5 000 tph of solids make trommels the preferred equipment for this application.

Wet screens utilize spray nozzles and water along with screen vibration in the sorting process, while dry screens use vibration only. There are different types of screening equipment, which are discussed below. Trommel Screens. Trommels are widely used in gold mines since they are extremely efficient and very effective at recovering fine gold.
The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product. Trommel Screens are attached to the end of grinding mills and scrubbers to perform a variety of screening functions. The trommel screen comprises the rubber lined steel frame and replaceable screening surface.
Trelleborg is able to design, size, supply and install screening panels for vibrating screens, SAG and Ball Mills and Scrubber Trommels. Trelleborg Rubber Screen Panels are ideal for bottom deck applications where binding is a problem. Trelleborg supply trommel panels in various rubber compounds and PU.
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 ...

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
SAG mill product feeds two parallel ball mills of 6.6 m×11.1 m (internal diameter×length), each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of ...
The SAG mill has a mill diameter of 24 ft (7.3 m) and an effective grinding length of 18.5 ft and a structural charge mass of 315 t, Condor Gold said. The structural design ball charge is 11% with a structural design load volume of 35%. Specific gravity of the material is 2.55.
Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on ...
Oct 01, 2009 Having related SAG mill throughput to SAG mill power and the ball mill circuit P 80, the data was then reduced to a series of curves representing the relationship between the SAG mill specific power consumption (S.P.C.), which is the SAG mill power draw divided by throughput, and the ball mill P 80 for each UGM. Fig. 3 shows the six resulting
SAG Mill Trommel Screens The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product. Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 5 000 tph of solids make trommels the preferred equipment for this application.
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
Popular Applications for Rotary Trommels. The tumbling action of the Rotary Trommel allows accurate sizing and separation that is beneficial for a variety of customers, including those looking to upgrade metallics after mass-burn solid waste incineration, to reclaim wood chips in sewage sludge composting, for accurate size separation of difficult-to-screen materials in municipal …
The Contender™ Series is our newest line of premium spare parts for non- grinding mills. The line includes grinding mill heads, shells, gears and pinions, main bearings, trunnions, trunnion liners, and more for select machines. For certain designated parts, additional enhancements have been made for increased safety and reliability.

For example, the third deck would be 80% as effective as the top deck. Wash water or spray will increase the effectiveness of the screens with openings of less than 1 in. in size. In fact, a deck with water spray on 3/16 in. openings will be more than three times as effective as the same size without the water spray. SCREENING
