Apron feeder is generally divided into heavy, medium and light three kinds, is a concentrator commonly used feeding equipment.Light apron feeder is a continuous feeding machine, which is suitable for short distance conveying of bulk materials with particle size of 160mm or less.In mines, concentrators, chemical industry, cement, building materials and other departments, widely used from storage silo to crushing, transportation and other machinery for uniform continuous feeding.It can be mounted horizontally or diagonally with a maximum upward inclination of 20 degrees.Generally, it is suitable for materials with loose density less than 1200kg/m3, block weight less than 140kg and temperature below 350℃.
Medium apron feeder is intermittent feeder, suitable for short distance conveying of bulk material with particle size below 400mm.In mines, concentrators, chemical industry, cement, building materials and other departments, widely used from storage silo to crushing, transportation and other machinery for uniform intermittent feeding.It can be mounted horizontally or diagonally with a maximum upward inclination of 20 degrees.Generally, it is suitable for materials with loose density less than 12400kg/m3, block weight less than 500kg and temperature below 400℃.
Heavy-duty apron feeder is the auxiliary equipment of transportation machinery. It is used as the continuous and even feeding material from the silo to the primary crusher in the crushing and grading workshop of a large concentrator, and can also be used for short distance transportation of materials with large particle size and specific gravity.Can be mounted horizontally or diagonally with a maximum inclination of 12 degrees.In order to avoid the material directly hitting the feeder, it is required that the bin will not be emptied. The tensioning support adopts the structure of section steel and bolt connection, which is beautiful in appearance and easy to assemble and disassemble.For heavy and extra-heavy tensioning devices, a set of springs is added to cushion the vibration absorption.In addition, there are the following two features:
(1) The screw of the tensioning device of medium and light apron feeder is located above the slide seat and placed under the inverted equilateral Angle steel, and the screw part is free from pollution and damage;For heavy and extra-heavy product tensioning devices, screw through the center of the slide seat.
(2) The tensioning device can be divided into standard type and heavy type, and it is serialized and generalized with the lower part tensioning device of bucket elevator.The head bearing seat is not supported on the frame horizontally, but is connected to the frame vertically with four bolts.Thus, on the one hand, the bearing capacity is consistent with the working tension direction, and the bearing capacity of the bearing capacity and the connecting bolt is improved. On the other hand, the space size is reduced.The pitch of 228.6 mm (9 inches) high strength bulldozing tools and forging chain for traction, two chain around installed in the head of a driven sprocket and body got behind a pair of tension wheel seal at the end of the closed loop, in two rows of chain assembly on the each link of overlap each other, the transport of heavy structure trough and become a continuous transmission line can carry enough material.The dead weight and material weight are supported by multi-row support wheel, chain support wheel and slide beam mounted on the body.The transmission system is connected with the reducer by the AC frequency conversion motor, and then the carrier mechanism is driven at low speed by the expansion sleeve and the driving device.The material discharged from the tail bin is transported along the transport line to the front of the body and discharged to realize the purpose of continuously and uniformly feeding to the working machinery below. Purpose of apron feeder
Apron feeder is a continuous transport machine widely used in mines, metallurgy, building materials, ports, coal and chemical industry and mining enterprises.It is mainly used for supplying and transporting all kinds of bulk heavy and abrasive bulk materials uniformly from the storage bin or transfer funnel to the crusher, batching device or transportation equipment.It is one of the important and essential equipments in the process of ore and raw material treatment and continuous production.
