Determination of the elevation of the main flat mouth

    From the perspective of mineral deposit development, the lower the elevation of the main flat shovel, the more reserves will be developed with the flat raft. However, the elevation of the main level is often limited by the elevation of the ore deposit of the ground mine, which must be adapted to the elevation of the mine.
When the ore main adit electric locomotive directly transported to bunker by beneficiation plant, the main adit port downhill elevation should reach 3 ~ 4 ‰ receiving bunker receiving mine mouth elevation; the use of automobiles or belt When the conveyor is transported, it is determined by the terrain and the allowable running slope of the equipment. Sometimes the ore needs to be shipped out, and the ore level of the mine bin is related to the loading height (with or without a mine bin) (loading a train or loading a car); if it is transported by an aerial ropeway, the elevation of the mine mouth It should be able to meet the needs of the height difference of the coarse, medium and ropeway stations. When the elevation of the selected plant is very different from the height of the main flat, the ore needs to be transported to reach the plant. At this time, it is determined only by the reasonable elevation of the main flat.
In some mines, the main flat sluice and the concentrating plant are uncoordinated by the ore level of the mine bin, causing the electric car to move uphill, thus affecting the traction of the electric car. In addition to special conditions, it should generally be avoided.

PTA welding technology is one of surface strengthening methods, which has high deposition rate, low dilution rate, and could be applied with many kinds of powder. The manufacturing craft of PTA powder is normally gas atomization, which reduces satellite of powder. We supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based alloy powder, Cobalt-based alloy powder and Mixed Powder.

Nickel Based Alloy Powder possesses high temperature resistance and wear resistance, it is the most popular alloy powder applied by PTA welding both domestically and internationally. Coating hardness is within the range of HRC 30-60. It could be applied to various industries like agriculture, plastic, paper, marine and steel making where wear and corrosion protection needed. Some examples are plunger, moulds, pump leaf and screw.

Iron Based Alloy Powder is more widely used and a more economic choice. With high abrasive resistance, it is more commonly applied to mining tools, drilling tools and mixers of iron and steel making industry, coal industry, shaft, oil and energy industry.

Cobalt Based Alloy Powder is recommended for corrosion and oxidation resistance, with better hot hardness values than equivalent Nickel based alloy powder. It is widely applied to steel making industry, coal industry and mining industry.

Mixed powder mainly refers to NiCrBSi mixing with other hard-phase powder such as cast tungsten carbide and other cemented alloy powder, which allows the powder better hardness around HRC60 and excellent abrasion resistance.

Mixed powder is more often used for mining equipment for oil sands, lignite, oil drilling tools, excavator buckets, extrusion screws for plastic processing, grain and oil processing, etc.
