Apron feeder in coal handling plant is an indispensable equipment in the continuous production process, especially suitable for conveying large and sharp materials. This series of machine has the characteristic of simple structure, reliable operation, long service life, easy installation and maintenance, etc, it has no special requirements on material granularity, block, and working environment, and the weight of transporting single material (piece) can reach 70-120 kg, apron feeder can be used for conveying various lumpy or loose materials from storage hopper to sizer crusher,conveyor or other working machinery along the horizontal or inclination direction.
Apron feeder in coal handling plant is generally divided into three kinds of heavy,medium and light,is commonly used in coal handling plant feeding equipment.

Light apron feeder is a continuous feeding machine,suitable for short distance conveying of lumpy material with feed size below 160mm .it is widely used to uniform and continuous feeding from the storage bin to sizer crusher and other conveying machine.it can be installed horizontally or inclined,with a maximum upward inclination of 20 degrees.Generally,it applies to convey the material with loose density less than 1200kg/m3,lumpy size less than 140kg ,and temperature less than 350℃.
Medium apron feeder is a intermittent feeding machine,suitable for short distance conveying of lumpy material with feed size below 400mm .it is widely used to uniform and intermittent feeding from the storage bin to sizer crusher and other conveying machine.it can be installed horizontally or inclined,with a maximum upward inclination of 20 degrees.Generally,it applies to convey the material with loose density less than 2400kg/m3,lumpy size less than 500kg ,and temperature less than 400℃.
Heavy duty apron feeder is the auxiliary equipment of transport machinery,it is used for continuous and uniform feeding material from silo to primary sizer crusher in large open-pit coal mine,and can also be used for conveying material with large particle size and specific gravity in short distance.it can be installed horizontally or inclined,with a maximum upward inclination of 12 degrees,in order to avoid the material directly hit this apron feeder,it is required that the silo does not appear to be discharged empty.
