Gold ore is an important stone, but gold in the ore is very low, in order to extract gold, the ore should be processed by gold ore processing plant. In this procedure, many gold ore processing equipments can be used, such as gold refining and beneficiation equipment, however the ore firstly must be crushed and grinded, thus the gold is separated from the ore.

Gold ore Processing Machines

Kefid is a complete gold processing machine manufacturers and supplier inChina, We supply gold processing equipment and gold processing plant for gold mining business. The mined gold ore is crushed to maximise the surface area for gold recovery. The gold ore crushing circuit contains primary crusher, the secondary and tertiary crushers and the conveyor, screening etc. This fine gold crushed by gold ore crusher is recovered by passing the ore through a ball mill to reduce the particle size right down to around 0.2 mm. On this process the finely ground ore is included tanks with certain chemicals that selectively attract the wanted particles.

Gold Ore Processing Method

Usually, gold continues to be recovered looking at the ores in several ways.  Any method of treating gold ores need to take good thing about the natural characteristics of the metal. Cyanide solution, unlike other liquids, has the capacity to dissolve gold, and so, is utilized within the processing of gold ore. When in solution, cyanide slowly attacks fine particles of gold and ultimately dissolves them. It’s strange, but fortunate, a weak cyanide solution attacks the gold particles faster than the usual strong solutions.

Grinding process is gold processing line’s stage two, after gold ore crushed, need gold powder, to process gold, grinding machine is effective, ball mill processing gold, stamp mill, sag mill, Raymond mill, vertical roller mill, process machinery. If you want gold ore powder, gold flake after gold crusher machine process, have to go through grinding process. We could use ball mill or any other grinding mill as gold grinding machine. The finished size cans up to 0.005mm.

Kefid can be a professional gold ore crusher and gold ore grinding mill machinery manufacturer inChina, and has formed a whole product chain that can take crushers and grinding mills since the main products. Now, our products have exported to many countries,Libya,South Africa,Vietnam,Indonesia,Philippines,Pakistan,Brazil,Egypt, Zambia etc.

Traditional methods, the ball mill during the processing of materials usually can play two effects, one is broken effect, one is the grinding effect. General sense, breaking effect can be broken using other ancillary equipment to complete.The ground level of the direct effect of the impact of factors can be attributed to the control of ball speed.

As a general rule, the speed of ball mill mainly from the basic power distribution equipment and gear drive gear and pulley device control.For large ball, since the drive motor to start the beginning of a great loss when the energy, and because the ball inertia force can not effectively use reducer mill to effectively control the speed in a short time.In cement production, cement ball mill into production, its breakdown of the number of cement particles and cement products taste directly linked to the size of ball speed.Well, that is, as long as improve their speed and the speed control system through the material out of a difference in their level of production or output to maintain a constant speed changes can greatly status companies to create more profits. However, because there are some reverse gear torque limit, can not indefinitely increase the speed of ball mill, after reaching a certain level, if that deliberately continue to increase speed, often driven gear coil mill burned, resulting in equipmentdiscontinued, the general maintenance cycle mill in 1-2 weeks.Such consequences are no different from a serious economic consequences for enterprises. 

Correct operation of the cement ball mill method
1.planetary ball mill gear dust cover must be tight to prevent dust, sand intrusion.

2.if found with the main gear bearing sediment may or invasive treatment should be immediately stopped and cleared, and definitely not delay.

3.the planetary ball mill large tile heating, the occurrence of an accident or near Burnt Burnt should take immediate measures for forced cooling may not be immediately stopped, to avoid causing “axle” vicious accident.

4.must be strictly enforced to the mining, water supply, add the ball of the provision prohibiting overload, attention to prevent “belly up” phenomenon, while to the amount of ore is not too small.Also not allowed to load Operation, avoid to damage the liner.

5.fixed ball screws should be added hemp liner ring seal to prevent leakage, leakage of slurry.

6.the gap between the liner for the 10-20mm for the replacement (available when oxygen welding cutting too tight).

7.the planetary ball mill no more than two consecutive start, the first and second should be an interval of 5 minutes.Starting the third time must be approved by electricians, fitters with the examination before starting.

8.the same workshop with several ball shall not also start two synchronized machine.
