DOVE Mobile Hard Rock Plants are engineered for complete comminution of the material through multiple stages of crushing and grinding cycles, and efficient processing and recover of the liberated metals and minerals through effective and advanced separation and concentration circuits.

DOVE Mobile Hard Rock Plants are designed for the highest recovery in the industry of the liberated particles of gold, platinum, light metals, base metals, ferrous metals, sand, gravel, and coal, down to micron size.

DOVE Mobile Hard Rock Plants’ exceptional portability, productivity, efficiency and quality deliver results that are unparalleled in the mining industry.

DOVE Mobile Hard Rock Plants and recovery methods vary depending on several factors, including the size of the rock, the rock’s condition, the hardness of the materials, mineral composition in the ore, specific gravity and other characteristics and specifications of the elements to ensure the efficient and highest recovery of the minerals production.

Hard rock mining is the process of extracting metals and minerals encased in rocks (primary deposits). Hard rock ore can contain metals, minerals such as gold, platinum, silver, iron, copper, manganese, zinc, nickel, tin, lead, zircon, etc.

The major components of DOVE Mobile Hard Rock Processing Plants consists of the following:

1. FEED HOPPER

The feed hopper is described as a large bin above the crusher into which the ore is dumped prior to being discharged into the primary crusher. In certain cases the feed hopper will be configured with static or vibrating grizzly.

2. VIBRATING FEEDER / VIBRATING GRIZZLY

A feeder at the bottom of the hopper helps transfer the ore to the crusher evenly and continuously. It can simultaneously screen materials roughly and increase the practical handling capacity of the whole production line.

3. PRIMARY JAW CRUSHER

The first step of rock reduction process from large particles into small pieces is running them through a DOVE primary Jaw Crusher, a crusher that takes the rocks and crushes them into smaller pieces. DOVE Jaw Crushers have two opposing ribbed panels, or jaws, with one jaw moving forward and back to crush raw material against the fixed jaw. Only material that has been crushed to a size equivalent to the opening at the bottom of the jaws falls through the bottom of the machine. This sizing is determined by the closed side setting of the jaw panels. Jaw Crushers exert more crushing power and are the best choice for very hard rock like granite and abrasive rock.

4. SECONDARY CRUSHER

A secondary crusher is one that takes crushed material out of a primary crusher and reduces the product further. DOVE Jaw crusher or DOVE Cone crusher depending on the hardness and rock condition can perform as the secondary crusher stage. After materials are crushed into the desired output size, it will go further to the next stage, which is grinding.

5. BALL MILL

The 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 balls drop from near the top of the rotating hollow cylindrical shell. The output materials will be feed to the processing and recovery machines.

6. Processing and recovery

Depending on project requirement DOVE incorporates advanced DOVE Vibrating Screen, Concentrators, Magnetic Separators, Shaking Tables,  Rotary Dryers,  and Flotation Process for recovery of minerals with the highest efficiency.
