What Are The Tips For Choosing The Motor And Reducer Of Feeder Breaker
The feeder breaker produced by our company mainly adopts four combination forms. One is composed of a scraper conveyor and a hammer crushing unit, another is composed of a scraper conveyor and a gear crushing unit, and the third is composed of a heavy-duty apron feeder and a hammer crushing unit as well as a heavy-duty apron feeder and a gear crushing unit. It is widely applied in industries such as coal and mining.
The main structure of the heavy-duty plate feeder: The plate feeder is mainly composed of a variable frequency motor, a reducer, chain plates, chains, drive wheels, etc. Baffle plates are set on both sides of the plate feeder, and protective devices are set at the sprocket to prevent materials from falling in. The plate feeder is equipped with safety protection devices such as overload and stall.
The feeder breaker reducer adopts a planetary reducer with a large speed ratio and high torque, and is supported by a torque arm suspension, eliminating the need for foundation support. Select well-known brands at home and abroad. The reducer has good sealing performance and no oil leakage occurs. The reducer is easy to replace and disassemble. A self-positioning block is designed between it and the gear coupling box to achieve quick alignment and installation. The reducer is equipped with an intuitive oil level indication device, an appropriate fan cooling system, oil temperature and other detection devices, as well as an input shaft bearing temperature detection device, and enters the centralized control. We select well-known domestic and foreign brands. The variable frequency motor is a high-efficiency and energy-saving motor. This motor has low energy consumption, high mechanical power, and excellent transmission efficiency and energy-saving effect. It is widely used in heavy-duty and large-capacity conveying equipment. It is a product that complies with the latest national energy-saving standards. Insulation class: F grade, protection class: 1p55, frequency 0-50hz, stator winding made of high-quality copper core, large temperature rise margin, long service life, cooling method ic416(independent air cooling), motor continuous operation s lead. It is equipped with bearing temperature measurement and winding temperature measurement, and can be connected to the operation control system of the plate feeder. An independent temperature measurement junction box is set up, and the motor is equipped with an anti-condensation heater.
The feeder breaker hydraulic coupling (optional for the crushing part) flexibly connects the motor and the reducer by the kinetic energy of the liquid, which can buffer the excessive impact force and torque generated during crushing and reduce the inrush current to the power grid. It is also equipped with a pressure explosion-proof structure explosive plug and a temperature overheat protection fusible plug, which have overload protection function. The reverse installation working mode improves the coaxiality of the drive unit, reduces circular runout, and prolongs the service life of the drive unit. B. Heavy-duty industrial reducers (optional for the crushing section) the heavy-duty industrial reducers used in the crushing section are imported from germany, and the cooperative manufacturers include siemens flender, sew, etc. This series of gear reducers feature light weight, small size, wide range of transmission ratios, high efficiency, smooth operation, low noise and strong adaptability. They are widely used in metallurgy, mining, lifting and transportation, power, energy, transportation and other industrial sectors. C. Self-aligning drum gear coupling the self-aligning drum gear coupling features adjustable axial, radial and angular displacements. Compared with peer manufacturers, advantages: Excellent adjustment effect; the shear pin has the function of protecting the power unit and is very convenient to replace. Abandoning the traditional key connection (hot installation method), it adopts a high-torque expansion sleeve/conical sleeve connection, which is convenient and quick to disassemble.
The above are our selection tips for the motor and reducer of feeder breaker. To achieve better usage results, we usually choose foreign big brands such as siemens, sew, and flender for our customers, which can ensure better quality.
