The screening effect of the trommel screen will be better. For screening dry materials, the vibrating screen is not easy to block holes, and the screening effect is better. 6. Different screening accuracy. The vibrating screen is a screening equipment with a vibrating motor as the vibration source, so the screening accuracy is high.
SAG Mill Trommel Screen. A SAG Mill trommel screen lets you control the true discharge size of your SAG mill or the transfer size to the downstream Ball Mill circuit. A well sized trommel should not let rocks pass to the Ball Mill if they are to be more than say 5/8″ or 16mm. In the image case below, strangely enough, is the mill shell ...
Grate discharge heads for ball mills are completely assembled in the shop, with grates, clamp bars, pan liners, and center discharge liners in place. ... Mill FEED CHUTE. If a scoop feeder, combination drum scoop feeder or drum feeder is supplied with the mill, it should be mounted on the extended flange of the feed trunnion liner, matching the ...
A trommel is a rotary cylindrical structure that is rigidly attached to the discharge end of a mill. The intended operation of the trommel is shown schematically in Fig. 1. It contains moulded screen panels or wire mesh and can have different aperture configurations in each axial section depending on the intended duty.
In this case the grinding circuit comprises an open circuit rod mill followed by a closedcircuit ball mill. The ball mill is most often closed over a classifier like a hydro cyclone (Fig. ) or DSM style screen with a fine cut of mm. The course material is returned to the ball mill feed and the fine screen underflow reports to the ...
We recently converted our 18X11 steel lined Rodmill to rubber lined trommel discharge Ballmill to improve grinding efficiency and increase throughput. Our rodmill used to run 120 tons/hr at a critical speed of % with rods diameter of 3". ... also ball mills generally work better in closed loop system, while rod mills often work in ...
This mill is constructed so that there is extreme flexibility of operation. Additional machines can be added as desired, such as a second 18″ diameter shell to the Ball Mill, another 2cell flotation machine, a second classifier if required, etc. LIST OF EQUIPMENT. 1—5″x 6″ Type "H" Jaw Crusher 1—Belt Ore Feeder 1—30″x 18 ...
Types of Mill Discharge SteelHead BallRod Mills are available in any one of five different types of discharge: Overflow, perforated overflow, return spiral, grate, and
A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solidwaste processing industries. It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material ...
As illustrated in Figure 2, the grinding circuit includes a SAG mill (9754 mm diameter and 3886 mm length), hydrocylones and also two ball mills (5029 mm diameter and 7620 mm length). In most cases, SAG/AG mills may be employ two different approaches to regulate the particle size of mill discharge. The first one involves the grates and the ...
SAG mill and two ball mills in closed circuit with cyclones. Two pebble crushers treat the SAG mill discharge trommel screen oversize material. The crushed product is combined with the SAG mill feed. Project economics dictated maximum throughput through a single line comminution circuit. Hence the selection of some of the largest
No need to suck out dust A quarry (capacity 500 MTPH [550 STPH] ) with a very high content of silica in its rock, reduced the need for sucked air from 530 thousand m3/h to 35 thousand m3/h (19x106 ft3/h to 12x105 ft3/h), the dust content from 25 mg/m3 to mg/m3 ( lbs/in3 to 2x1011 lbs/in3) and the noise level from 95 dB to 76 dB using dust seals, screening media and chute ...
Mobile Gold Washing Plant Mobile Rotary Scrubber Mobile Trommel Screen; ... Main Equipment: Ball mill, gold centrifugal concentrator, ... It's with PP material feeding chute and discharge chute. And it's with big and higher channel frame to make it stronger. The 6S shaker table is a safe operation and the table desk color is as per customer ...
Using DEM software, we analyse your trommel's material . distribution in order to optimise your screening media . configuration. Optional deflectors . Installed between the mill discharge trunnion and the . trommel, deflectors provide a homogenous and controlled . feed of the mill discharge pulp onto the trommel screening surface.
Our Ball Mill Liners are the result of stateoftheart softwaredriven designs with industryleading inspection data, achieving an optimal charge trajectory and rate of wear life for your ball mill machine. Multotec's installation expertise is based on over 50 years of experience. We ensure that your ball mill liners are fitted with precise ...
Our range of gold mining trommels includes trommels with modular and cast panels and mill trommels. Trommels are fitted with screens with a wide range of apertures to achieve your required cut point according to the coarseness of the gold ore. Gold trommel diameter: 950 5 500 mm; Gold trommel length: 1 200 5 500 mm
Grate Discharge Ball mills with low pulp levels benefit from the full impact of the grinding media acting on the ore particles, as it falls into the shallow pulp. With a deep pulp level the grinding media is cushioned in the pulp, thus losing its energy and reducing its grinding ability. Grate Discharge Ball Mills have shown 25% to 45% more ...

We refurbish, design and manufacture an extensive range of highquality mills and mill components to exacting standards, offering you a turnkey service that's backed by two decades of engineering expertise. BROCHURE. Finite Element Analysis (FEA) Ball Charge Trajectory Modelling ...
With regards to " 4" media, typically for Ball mills of this size (16'), max size of ball used should be around the 5060mm. I feel that a 4" ball in a 16' Ball Mill is too large and more suited to SAG Milling. You risk damaging liners (rubber, composite or full steel) as well as trommels and feed chutes in the process.
The blind trommel is a short extension that bolts directly to the discharge flange of the ball mill. The function of the blind trommel is to transport the mill discharge material through the magnetic field. The blind trommel is fabricated from stainless steel and has an abrasion resistant wear liner.
The ball mill machine is known as a ball grinding machine. It is a wellknown ore grinding machine and is widely used in mining, construction, and aggregate application. JXSC started manufacture the ball mill grinder since 1985, supply globally service includes flow design, manufacturing, installation, and free operation training in mining ...
