Product introduction:
Coal briquette machine can also be called pulverized coal pressure ball machine, can be used to suppress the coal, iron, briquette ball press molding process cold pressing, hot pressing molding, cold pressing; cold pressing and molding binder and binder less molding, binder mainly. According to the situation of our country, the powder is formed by adding binder, middle and low pressure, non-drying and cold pressing.
Coal briquette machine can be used to suppress the end of coal, iron, coal, aluminum, iron, iron oxide, carbon powder, charcoal powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke and other various kinds of powder, powder materials, waste, waste, widely used in refractories, power plant, metallurgy, chemical industry, energy, transport, heating and other industries, the pressure ball machine production of molding material, environmental protection and energy saving, convenient transportation, improve the utilization of the waste material, and has good economic benefit and social benefit. -
Working principle:
Host by electromagnetic adjustable speed motor provides the power to the belt wheel, a cylindrical gear reducer; the pin coupling is transmitted to the drive shaft. The driving shaft and the driven shaft are guaranteed to run synchronously through an open gear. A hydraulic device is installed behind the passive bearing seat. The screw feeding device is driven by an electromagnetic speed regulating motor, and is driven by a belt wheel and a worm reducer to force the material to be pressed into the feed inlet. Due to the electromagnetic adjustable speed motor constant torque characteristics, when the spiral feeding machine material pressure feeding amount and the host material is equal to the amount required, can maintain constant feeding pressure stabilizing the quality of pellet. If the feeding amount is too large, then the electrical overload feeding device; the feeding quantity is too small not into a ball. So skilled operation is an important condition to ensure the normal operation of the press.
The hydraulic protection device is driven by the hydraulic pump, the high-pressure oil into the hydraulic cylinder, so that the axial displacement of the piston. The front of the piston rod is connected with the top of the head to meet the requirement of production pressure. When the between the two rollers feed or into the metal block, the piston rod of the hydraulic cylinder pressure overload, the hydraulic pump will stop, energy storage device to pressure changes from buffer, overflow valve open return oil, piston rod displacement pressure and gap increase so that a hard object through a pressure roller, system pressure recovery normal can to protect the pressure roller is not damaged.
