CGN wet pan mill gold mining also called wet gold grinding machine is used for amalgamation gold extraction of sulfide-free gold mines and is suitable for operations in field areas without power supply by equipped with a diesel generator.

1. The Application of Wet Pan Mill gold mining CGN wet pan mill also called wet gold grinding machine is used for amalgamation gold extraction of sulfide-free gold mines and is suitable for operations in field areas without power supply by equipped with a diesel generator. This machine, which has functions of crusher and ball mill, can crush the ores once for all in the purpose of gold extraction in amalgamation method.

3.Working principle of Wet Pan Mill The diesel generator is responsible for power supply in operation. The reducer and the interlocked main shaft are driven via the belt to run the grinding wheel and grind the ores. When crushed to 0.05-1mm, the ores are added for mercury cycle operations. When extracting mercury cream, the machine should be stopped.

4. Principle of Amalgamation for gold Amalgamation method is to extract gold particles in the ores. When crushed to 0.05-1mm grain size or more, most of the gold particles can be separated and drift in the water. The gold particles in 0.05mm-1mm grain size are surrounded by mercury, and compound reaction occurs to generate mercury paste of AuHg2, Au2Hg and Au3Hg, which is also known as gold amalgam. Since gold and silver are usually associated, there is silver in the mercury paste in addition to gold, and is separated from other metallic minerals. The amalgamation process takes place under the infiltration effect of water, gold and mercury. The recovery of gold depends on grinding size, cleanliness of gold particle, ore pulp concentration, temperature, and pH value. To save the consumption of mercury, the ores are usually ground to 0.05-1mm before added to mercury. The mercury per ton of ore depends on the grade of raw ores. 2% of lime should be added to reduce the viscosity of the ore pulp, the pH value of the ore pulp should be adjusted to PH8-9, and the concentration should be in 30%-40% for amalgamation operations. After amalgamation, water is added to dilute the ore pulp for mercury deposition and accumulation. The mercury paste can be recycled after the gold particles treated and removed.

6.Installation, Usage and Maintenance 1. The machine should be installed on a concrete foundation, placed on level and the anchor bolts should be tightened. 2. Operation steps: Shift the clutch handle to ON position to start the diesel generator. Engage the clutch to drive the host when the operation is normal, and feed materials and water for operation. Disconnect the clutch to stop the machine before cleaning up the mercury paste. 3. Add water, engine oil and diesel oil to the diesel generator on regular basis. See the instructions for details. Lubricate the clutch and upper bearing cover once and add engine oil into reducer once every 30 days. 4. The power section should be kept from sunlight and rain, and ore pulp infiltration to be avoided in operation.

They are highly efficient Grinding mill machines, designed for grinding applications, where fine material is required. DOVE Ball Mills are used in supplied and applicable for wet and dry grinding applications within the following branches of industries:

DOVE ball mills is a rotating horizontal cylinder that tumbles the material to grind with a certain media. The standard media that we use in our ball milling process are the steel grinding balls, however depending on the specific application, we can configure the grinding mill with different media.

DOVE supplies various types and sizes of Ball Mill Balls, including; Cast Iron steel Balls, Forged grinding steel balls, High Chrome cast steel bars, with surface hardness of 60-68 HRC. DOVE Ball Mills achieves size reduction by impact and attrition. When the cylinder rotates, the balls are dragged to almost the top of the shell, and from there, they fall unto the material, which lead to the material breaking due to the impact.

DOVE Ball Mills are used in hard rock mineral processing plants as an ore-dressing step to grind the rocks into fine powder size, liberating the mineral particles from the rocks. This will ensure that the ore is well prepared for the next stage of processing and optimize the recovery of the minerals.

DOVE ball mill is integrated and used in DOVE Portable and Semi-Stationary Hard Rock plants (Hard Rock processing plants) to efficiently grind the ore from primary deposit until the liberation size of valuable minerals is reached. DOVE ball mill is the key grinding equipment after material is crushed. It is used to grind and blend bulk material into powder form using different sized balls. The working principle is simple, impact and attrition size reduction take place as the ball drops from near the top of the rotating hollow cylindrical shell of the Ball Mill. The output materials will be feed to the processing and recovery machines.

DOVE Ball Mills are deigned for either wet or dry grinding of materials, in various models, and in accordance to the processing and the crushing plant design, to cater to the liberation size of the minerals and the hardness of the ore.

DOVE supplies two different kinds of ball mills Grate type, and Overfall type. The difference between the two type is according to their ways of discharging material, and the plant flow design specifications.

The Grinding Balls will grind the material into powder size of 20 to 75 micron. In mining operations, this will allow for the liberation of gold and other precious metals that are hosted by the rocks. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties, specification and advantages.

Media Size: The grinding media particles should be substantially larger than the largest pieces of final material after grinding. The smaller the media particles, the smaller the particle size of the final product.

Composition: Each ball mill application has different requirements. Some of these requirements are relates to the grinding media being in the finished product, while others are based on how the media will react with the material being milled. Therefor, grinding media selection plays major factor on the final milled product.

Contamination: In certain grinding mill process, low contamination is important, the grinding media may be selected for ease of separation from the finished product, for example steel dust produced from steel balls can be magnetically separated from non-ferrous products. An alternative to separation is to use media of the same material as the product being milled.

Corrosive:Certain type of media, such as steel balls, may react with corrosive materials. For this reason, stainless steel balls, or ceramic balls, and flint grinding media may each be used when corrosive substances are present during grinding.
