Industrial Test
PHASE #3
We can feed our existing plants with an industrial sample of the customer raw material to produce industrial test on it.
We can offer a unique service to our customers: we can feed our existing plants with an industrial sample of the customer raw material allowing the customer technical staff to join the trial and understand in detail what kind of plant will be supplied, knowing in advance the production rates, the energy consumptions and even the production troubles. In addition, the customer can obtain an industrial sample of the final product manufactured in his future plant before having built it. This sample can be introduced to potential customers for verifying their interest and collect their purchase commitments.
DRY PROCESS
Crushers are machines designed to reduce large rocks into smaller rocks, gravel, or dust. They are commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations. Each crusher is designed to work with a certain maximum size of raw material, and often delivers its output to a screening machine which sorts and directs the product for further processing. Typically, crushing stages are followed by milling stages if the materials need to be further reduced below 10-20 mm
Dryers are machine designed to remove the water from minerals by evaporation.
Traditional dryers (cocurrent or countercurrent) are characterized by the mono-directionality of the air flux.
On the contrary, our models (HED-13) use a central aspiration so that the inlet material passes through a first stage, cocurrent with the hot air generated by the burner and subsequently in a second stage countercurrent with the environmental air aspirated from the opposite side of the dryer.
This procedure permits to obtain an outlet sand at lower temperature and a significant reduction on energy consumption.
The reduction we can obtain by crushing is limited to a certain size (10 – 20 mm) for the final product.If we need further reduction we have to use a milling process which uses the rock mechanical forces of impaction, compression, shearing and attrition. Thanks to the MI milling process, we are able to liberate minerals trapped in rock crystals for further enrichment. Our milling machines (RHP) use the Auto-Comminution principle by which the material is forced to pass through two rolls and the milling is granted by the pressure between the grains. The result is a more efficient machine and a strong reduction in the energy consumption.
Optical sorting is the automated process of sorting solid products using cameras and/or lasers. The sorter, using well-defined accept/reject criteria, compares objects to identify and remove defective products and foreign material from the production line, or to separate product of different grades, colors, opacity and transparency.
Magnetic separation is a process in which magnetic material is separated and extracted from a mixture using a magnetic force.
Magnetic separators are ideal devices to deironing a wide range of sand materials. Paramagnetic minerals (hematite, biotite, ilmenite, ecc…) are simply captured byMAG-3’s powerful magnets. MAG-3 magnetic separators are particularly indicated for the iron removal of fine particle size products (typically from 0,1 to 1,8 mm).
WET PROCESS
The hydraulic washing is mainly used to separate clay minerals from sand or feldspar. The denser ores settle and are moved away by the spirals while the lighter particles are washed away.
It is used to have soft milling of hard materials for producing as less as possible fractions below 100 microns
Froth flotation is an ore beneficiation process in which valuable minerals are separated from worthless material by inducing them to gather on the surface of a froth layer.
The collection of these minerals on the surface is possible thanks to the introduction of air bubbles into the pulp which are able to trap the minerals.
The air bubble and mineral particle rise through the pulp to the surface of the froth that is present on the flotation cell. Even though the air bubbles often break at this point, the mineral remains on the surface of the froth and can be physically separated from the remaining pulp material and removed for further processing.
Leaching is the process of extracting substances from a solid by dissolving them in a liquid. In our beneficiation plant, it is used to reduce the content of iron oxide from ore using sulfuric acid.
