There are many different reasons for why a company might get rid of industrial machinery. Usually it is during an expansion or shrinking phase, where some of their machines can become unnecessary, long before they are actually technically obsolete.
There are generally other types of requirements for machines used in industry than those used for private businesses. It is always guaranteed that machines used in industry have a permanent level of high quality and robustness, are easy to maintain and have a reliable supply of spare parts. This means that even used industrial equipment for start-ups are a useful investment to ensure that the required productivity is met.
Wood is an extraordinary material, that provides a wealth of technical characteristics that no other material can. It is light, stable, affordable and available in various forms. This natural material is ideal for many different uses. There are a number of different woodworking machines available for efficiently processing wood.
Metal is the most used material when manufacturing industrial machinery and devices. Metalworking can take place in a variety of different ways. Casting machines and technology is used to form and shape metals. They are either poured into a pre-product or directly formed into the end shape, directly out of the mould. Extruder and die casting machines are used for this process.
After the metal is formed, it can be further processed. Rolling machines, metal-presses and welding machines are most commonly used for this. Metal is prepared for industrial machinery using separation processes by being rolled into sheets and then wrapped onto reels. Punching machines and machine tools are used to separate sheet metal. Cutting machines are used to process individual sheet metal. These are available in the form of flame cutters, laser cutters or water cutters.
All these machines are available used, in a variety of different levels of automation. This means that it is easy to find used industrial equipment that is best suited for the desired operation or task. Training facilities and small manufacturers usually prefer compact industrial machines that are primarily manually operated. Large machines with high output rates are best for producers of series components. The used market provides a variety of used industrial equipment ranging from completely manual to those that are fully automatic.
These machines are also supplemented by a number of different auxiliary materials, conveyor belts, turning stations, packaging machines or industrial robots to help increase the productivity of a facility. Even these machines are available in large numbers and in great condition on the used machinery market.
Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.
Based on abundant experiences on gold mining project, Prominer helps clients to get higher yield & recovery rate with lower running cost and pays more attention on environmental protection. Prominer supplies customized solution for different types of gold ore. General processing technologies for gold ore are summarized as below:
For alluvial gold, also called sand gold, gravel gold, placer gold or river gold, gravity separation is suitable. This type of gold contains mainly free gold blended with the sand. Under this circumstance, the technology is to wash away the mud and sieve out the big size stone first with the trommel screen, and then using centrifugal concentrator, shaking table as well as gold carpet to separate the free gold from the stone sands.
CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using otation and/ or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density. Then it is pumped to leaching plant and dissolved in aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon, and it is called Carbon-In-Leaching process (CIL).
Heap leaching is always the first choice to process low grade ore easy to leaching. Based on the leaching test, the gold ore will be crushed to the determined particle size and then sent to the dump area. If the content of clay and solid is high, to improve the leaching efficiency, the agglomeration shall be considered. By using the cement, lime and cyanide solution, the small particles would be stuck to big lumps. It makes the cyanide solution much easier penetrating and heap more stable. After sufficient leaching, the pregnant solution will be pumped to the carbon adsorption column for catching the free gold. The barren liquid will be pumped to the cyanide solution pond for recycle usage.
The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before mixing with uxes and melting. Finally, the melt is poured into a cascade of molds where gold is separated from the slag to gold bullion.
