This paper introduces the application range, characteristics and common models of apron feeder in coal handling plant.
apron feeder in coal handling plant product introduction
At present, the coal feeder commonly used in coal preparation plant is apron feeder, etc., they are the coal from the coal bunker or coal storage yard evenly into the conveying equipment or coal preparation equipment. Plate type feeder is divided into heavy plate type feeder and ordinary plate type feeder according to the size of bearing pillar pressure and the size of feeding particle size. In coal preparation plant, only light plate type feeder is generally used.
Its working principle for the apron feeder in coal handling plant in the coal storage through coal gate into the plate feeder, from the inside of the coal feeder conveyor measuring tape continuous uniform transmission the mill, in the bottom of the measuring tape is equipped with electronic weighing device, the device is mainly composed of high precision electronic belt scale, weighing sensor produces a proportional to the weight of the coal electric signal and speed sensor to detect belt speed Degree signal is fed into the integrator at the same time, and the instantaneous flow rate and cumulative quantity are obtained after the integrator calculation.
apron feeder in coal handling plant product overview
Apron feeder is widely used in building materials, metallurgy, electric power, coal, chemical industry, casting and other industries, especially suitable for conveying some high temperature, large block, with sharp edges and corners and strong grinding cut solid materials. In cement industry, it is the best choice for clinker transport at the end of vertical kiln. Models can be divided into light apron feeder, medium apron feeder, heavy apron feeder.
Apron feeder in coal handling plant product characteristics
1, traction chain adopts long pitch plate pin roller chain, chain parts are made of alloy steel material, and after scientific heat treatment, good wear resistance, high tensile strength, long service life.
2, the use of stamping groove, the middle with transverse reinforcement, groove rigidity is good, large bearing capacity. Trough bottom plate arc lap to prevent material leakage.
3, the driving motor adopts speed regulating motor, the running speed can be adjusted, so as to choose the conveying volume more reasonably.
4, the layout of a variety of forms, horizontal, inclined layout, and a variety of horizontal, inclined combination layout.
5, single conveyor length is less than or equal to 60m, lifting height is less than or equal to 30m.
6, the maximum transmission Angle 0-75 degrees. The material temperature is less than or equal to 600℃.
