Heavy apron feeder: the equipment can withstand large warehouse pressure, feeding particle size ≥mm.
Medium plate feeder: in principle, the equipment does not bear the warehouse pressure; Feed size < mm
Light plate feeder: equipment does not bear warehouse pressure; Feeding size ≤mm
Characteristics Of Apron Feeder
Features Of Loading
Heavy apron feeder in the force analysis to consider:
(1)Load Q of the material to be transported
(2) Load Q of material at Angle of repose in the warehouse.
(3) Cutting force between materials and materials in the warehouse during conveying.
(4) The impact force of materials on equipment when they fall into the bin.
(5) Operating resistance caused by the dead weight of equipment load.
(6) The equipment conveying materials and moving parts of the comprehensive friction resistance in the operation.
(7) The motor frequency conversion startup should consider the full load startup.
Medium and light apron feeders should be considered in force analysis:
Design And Structural Features Heavy apron feeder's characteristics are as follows:
(1)The circular arc structure of the plate feeder chain plate is made of Mn ~ MM. In addition, to wear resistance, it can also make the equipment do not leak when transporting materials.
(2) The apron feeder adopts die forging engineering machinery chain (tank chain), the material is good (chain: CrMo; Pin sleeve material: pin shaft: strength, long life, and do not need lubrication in operation.
(3) The plate feeder chain plate is supported by multiple groups of supporting wheels so that the supporting points of the chain plate are many so that each chain plate becomes a statically indeterminable beam. In addition to its good force, small deformation, and the supporting wheel built-in bearing, the equipment running resistance is small.
(4) Apron feeder drive device and spindle, sprocket and sprocket shaft are keyless connection (ring pin close connection) so that the whole machine assembly, maintenance is convenient, but also make the double chain synchronization accuracy is high, to ensure that the equipment in the operation of the failure rate is very low, the parts of the force balance, low damage rate.
（5）Apron feeder reducer adopts two-stage planetary plus right-angle reducer combined hard tooth surface reducer. It also uses a single point floating support, without foundation, to ensure the transmission precision of the reducer, but also reduce the cost of the foundation.
(6) The tension spring of the apron feeder adopts a compound rubber spring, which ensures the tension stability and is not easy to damage, and reduces the failure rate of the equipment.
(7) The vibration of the apron feeder is very small, it can not set anchor bolts. It only needs to be buried on the basis of some steel plates, good position equipment, and then the machine base point on the buried steel plate.
(8) Plate feeder adopts frequency conversion speed regulating motor speed, according to the user needs at any time speed regulation, to ensure different output needs.
