Have You Ever Heard the Flotation Separator?

Le 18 janvier 2014, 02:05 dans Humeurs 0

In the late 19th century and the early 20th century, the flotation cell manufacturing company put forward tank design. At present, the volume of the Flotation machinedesigned with this method can reach 150 m³, and the manufacturers are researching and producing even bigger flotation tank according to the production demands. The tank of this flotation machine is round equipped with bubble remover, bubble collector and ore discharging mouth as well as high-efficient level control system.

The flotation cell process makes the mining of mixed ore bodies efficient and economically viable. In a typical flotation cell, various parameters need to be controlled. These include surface level and interface measurement, slurry pH, flow-meters for flocculent agent dosing, slurry flow, compressed air flow, and valve control using electromagnetic flow-meters.

In the flotation separating process, the air amount through the ore pulp is determined by the circle rotary speed of the impeller of the flotation machine. In addition, increasing the rotary rate of the impeller will increase the amount of the air; however, this will over mix the ore pulp on some conditions, increase the impeller abrasion and energy consumption of the flotation machine and influence the production quality and shorten the service life of the machine. If necessary, we can increase the pressure inside the vertical pipe using an outside air blower and add air to it so as to relieve the abrasion of the impeller.

Accurate and reliable measurement is crucial during the process, as there needs to be a balance between the amount of base slurry and the amount of froth produced. Excess injected flocculent costs money, but is also expensive to remove from the process later down the line. The most common way to optimise the process is to measure the relative ‘thickness’ of the froth in relation to the level of the slurry in each flotation cell (http://www.sell-crusher.com/).

 

In the flotation separating process, the ore pulp flows through the flotation cell into the adjustable tailing down flow weir, and is absorbed on the impeller of the next cell, where it will get full mixing and inflation by the flotation machine again. The particles that are too heavy to flow into the down flow weir will be discharged from the sand discharging mouth in order to prevent the coarse particles from depositing inside the flotation cell.

Powder grinding mill is widely used in metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing. According to the fine grinding of materials and discharging materials fineness, milling machines can be divided into Raymond Mill, High pressure suspension mill, HGM Series powder grinder machine and so on.

Powder grinding mill is widely used in metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing.

Advantages of powder grinding mill:

(1) Environmental protection. It adopts an efficiency pulse dust collector, so there is no dust pollution in the complete operation process. In addition, it is equipped with a muffler and sound proofing room so that the pollution and noise can be reduced in accordance with the environment-protection standard, and surrounding environment is protected.

(2) High security and reliability. The operation which is inside of the grinding chamber is safe and reliable. Compared with an ordinary mill, there is not rolling axletree or screws, so there is no problem of wear of the axletree and other sealed parts, and it avoids the problem that the machine is damaged due to loosen screws.

(1) Low investment cost. With the same products' fineness and generator power, it has low investment cost, short return period and twice more output compared with the airflow mill, stirring mill or ball mill.

(3) Low wear and long service time of wear parts. All the wear parts are made of national anti-friction material. Their service life is longer than that of the wear parts of ordinary mill equipment (http://www.china-hxjq.com/n260.html). Generally, they can be used for more than one year.

(4) High powder output. With the same fineness and power consumption, its powder output is more than the airflow mill or stirring mill by 45%.

The Great Use of Gyratory Cone Crusher For Ore Industry

Le 18 janvier 2014, 02:04 dans Humeurs 0

With the crushing and screening industry continues to become bigger and stronger , the gyratory cone crusher developed to promote the rapid development of the iron ore industry . The domestic iron ore beneficiation enterprises reflect the full guarantee market supply, processing a large number of iron ore, is a very high challenge, visible production of iron ore market is infinite good.

Processing of iron ore exploration, mining, generally includes a head, two broken, screening, fine, dry, transport processes, iron ore is broken link is particularly important, usually into the dry separation of ore grain finer, containing iron ore by dry out of proportion is higher, choose the most economical mode of production, the maximum increase of iron ore dry separation rate, fine crushing equipment of many types, such as a hammer crusher, roll crusher (http://www.sell-crusher.com/pro/p12.html), spring cone crusher and so on, but these devices crushing principle each are not identical, suitable link also has limitations, HPC series hydraulic cone crusher overcome various difficulties, for iron ore crushing effect.

Due to the low overall level of development of the mining equipment in China , the mode of production of the domestic mining enterprises is still in scattered, small, chaotic state , resulting in a huge waste of natural resources and energy loss, caused tremendous damage to the ecological environment , iron ore stone processing equipment efficiency and energy saving is the key. Upper and lower ends of the gyratory cone crusher spindle are supporting iron ore crushing force can withstand greater stroke , plus special crushing cavity shape compatible with the laminated principle so that the broken iron ore has a higher crushing yield break than the old - fashioned spring cone efficiency of the device.

 

The gyratory cone crusher writing the myth of the iron ore industry. As long as the process of urbanization continue to promote economic development still remain stable, then the use of steel , iron ore must meet a certain number of. Improve the production of iron ore to meet the development needs is very important.
