Heavy duty apron feeder is a large machine that carries materials through the parts of a manufacturing or industrial process. These machines resemble short conveyor belts, and may also be known as plate feeders or apron conveyors. Apron feeder machines allow engineers and process managers to automatically control the volume of materials that are added to a process, and regulate the rate at which these materials are added. To withstand the heavy weight of these types of materials, the belt portion of the apron feeder is made from thick steel trays, pans or caterpillar chain plate. Chains along either end of the feeder help move the trays along the conveyor area, and are powered by an industrial motor or engine. In mining, the apron feeder carries rocks and minerals for crushing, or further processing.

Feeding machine main work is to put the motor power through reducer, it makes the eccentric connecting rod to do reciprocating motion, and makes the pawl driven ratchet drive sprocket rotates, thereby intermittent chain plate can move, so as to achieve the purpose of conveying material.

The machine is widely used in the crushing and grading workshop and cement, building materials and other industries, which can be used as a continuous and uniform feeding material to the primary crusher.

The traction chain with long pitch plate pin shaft roller chain, every parts of chain adopts alloy steel material, and through scientific heat treatment, wear-resisting performance is good, high tensile strength, long service life, introduce the stamping groove, the middle use reinforcing rib, the performance is good, large carrying capacity.
