Ball mill is suitable for grinding all kinds of ores and other materials. It is widely used in mineral processing, building materials and chemical industry. It can be divided into dry grinding and wet grinding. According to the different types of drainage, there are two types: grid type and overflow type.According to the shape of the barrel, it can be divided into four types: short barrel ball mill, long barrel ball mill, tube mill and cone mill.
The wet pan mill is a new mill, small investment, high yield, the production cost is low, good benefits.
Dry Magnetic Separator, Magnetic Separator Working . This dry magnetic separator has a high magnetic field intensity, its effective depth is larger, which guarantee good magnetic effect; Cylinder contains wear resisting rubber, which has a long service life, not only achieved standard production, but also improved the ore grade, saved the cost of.
The addition of lime in the flotation operation is usually carried out by adding the lime powder to the ore belt of the ball mill or adding lime milk or lime powder to the stirring tank before the flotation.
The mine, which has produced more than 2 Moz in its 26-year history, previously employed a flotation circuit consisting of a bank of eight mechanical trough cells in the rougher circuit, followed by two banks of 2 x OK3 Outotec cells as cleaners. The feed rate to the cells was between 90-105 t/h, at 50-55% solids. The overall flotation circuit was not performing at optimal rate due to entrainment problems in the rougher cells when feed density increased from 45% to 55% solids, typically at 105 t/h.
Four different amine collectors were investigated using the 16.3- percent-Cr2O3 Benbow-1 ore. The flotation procedure was as described previously. For each test, collector dosage was 0.6 pound per ton and H2SO4 consumption was 26 pounds per ton. Rougher flotation using Armac C yielded 79 percent recovery in a 40 percent Cr2O3 product. Results presented in table 4 show that Armac C, a primary coco-amine, was the best reagent.
The ore feed rate to the ball mill is controlled by the weightometer located on the mill feed conveyor which can be manually adjusted with in the control room to give a constant weight reading. The signal from the weightometer increases or decreases the belt feeder speed and adjusts the water addition to the ball mill (as a function of the actual weight reading). Both weight control and the proportion of water can be adjusted in the control room.

IFE magnetic drum separators are adapted tailor-made to the individual application. Drum separators with radial oriented magnetic fields are most suitable for interlinked material, as the pole changes on the casings surface allow for circulation and therefor open the links to set nonmagnetic particles free. An axial oriented magnetic field is generated by magnetic discs and is most suitable for non-linked material with high feed rates.
In the process of cyanide production, the control of lime is not paid attention to, and many mines cause losses. The ore in Inner since excessive addition of lime the gold leaching rate by 5% to 10%; a Shandong ore Again, a certain period due to insufficient amount of addition of lime, sodium cyanide consumption multiplied by 4. 82kg / t Increase to 9. 20kg / t and so on.
Zenith designs a variety of artifical sand making machines, which includes B Series Deep Rotor Vertical Shaft Impact Crusher, B Series VSI Crusher,etc. They are the most effective machines at present and applicable to crush various stones with different hardness in medium and fine crushing area. It is more advanced in intermediate hard, extra hard and abrasive material crushing.

The final design is a model 205 OCW50 Crossbelt Electro Overband Magnet, with the 17 kW electromagnetic coil, generating the strong magnetic field, cooled using recirculated oil. Efficient cooling of the electromagnet is critical as the magnetic force decreases proportionally to the rising temperature of the coil, Bunting said.
Vertical-shaft kilns ,: are the most popular type of kilns, having varying heights, diameters and constructional details. There are two types, namely mixed- (a) and unmixed-fuel type (b). The construction of a vertical shaft may be cylindrical, conical or a combination of both shapes with varying diameters in different zones (Fig.13(a)).
