The hydraulic protection device of the coal press equipment is that the hydraulic pump pushes the high pressure oil into the hydraulic cylinder to cause the piston to produce an axial displacement. The piston rod front joint is located on the bearing seat to meet production pressure requirements. When there is too much feeding between the two pressure rollers or the metal block, the hydraulic cylinder piston rod is pressed and overloaded, the hydraulic pump will stop, the accumulator will store the pressure change, the oil return overflow valve will open, the piston rod will be displaced, and the gap between the Pressure rollers so that solid objects pass through the pressure roller, and the system pressure returns to normal, which may protect the pressure roller from damage. This machine can adjust the pressure according to the pressure ball density requirements, and the production is flexible .
The briquetting machine can be used to compress various powders such as coal powder, iron powder, coking coal, aluminum powder, iron filings, iron oxide scale, carbon powder, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke powder, etc. Powder, waste and waste residue are widely used in refractories, power plants, metallurgy, chemical industry, energy, transportation, heating and other industries. The materials formed by the briquetting machine are energy-saving and environmentally friendly, easy to transport, and improve the utilization rate of waste. , with good economic and social benefits.
The roller skin of the briquetting machine is cast with 65 manganese. After special heat treatment, the hardness can reach more than 58 degrees. The roller skin is assembled in combination and can be replaced after wear. The mineral powder briquetting machine has a buffer device, which can better protect the equipment from the impact of hard objects. The mineral powder briquetting machine is designed with a ball bowl adjustable device, so that the two-roller ball bowl is always within the adjustable range and will never be in place.
