Apron feeder is a kind of special equipment for handling materials with strong impact and relatively large load. It has the advantages of slow running speed, strong impact resistance, strong continuous work and low maintenance cost. Power refers to the amount of work done by an object in unit time, that is, power is a physical quantity describing the speed at which work is done.
Apron Feeders. There are very few manufactures that offer a thru heavy duty steel flight feeder. Nortech builds what we believe to be the best on the market. We start with a very stout I-beam construction. On our smaller units (Up to 48") we use Berco D-4 sealed and lubricated rails with bolt on sprockets.

Apron feeders or grizzlies are generally used to feed quarry rock into a primary crusher. They are of a heavy-duty construction to take the shock from rocks dumped directly on them. To cushion the blow of material dumped on the feeder, a large hopper may be used to receive the dumped loads. The apron feeder …
Apron feeders are volumetric-type feeders, which means bulk density is used to determine the speed and power needed to extract a certain tonnage per hour of the material. The minimum bulk density is used to determine the speed, and the maximum bulk density establishes the power (torque) needed for the feeder.
An Apron Feeder is run at very low speeds and at a controlled. feed rate as it absorbs the impact loads of the material. falling from a dump truck or a front-end loader and is ideal. for withdrawing material from under a stockpile or. from under a Primary Crusher. Apron Feeders are of rugged, heavy duty construction and designed to handle large.
Discussion on the improvement design of apron feeders. The main reason for the mechanical failure caused by severe deformation of the board and load bearing shaft by the impact of materials is that the load bearing plate and load bearing shaft are stressed together and there is no supporting device in the middle part of the board.
Due to the heavy duty apron feeder need to drive the high load, feeder belongs to the constant torque device, on the assumption that the traction, certain torque is proportional to the radius of gyration, has nothing to do with the other parameters, and the size of the traction determines the traction, the make and model of the ...

Feeder load, initial condition, V, = 830.6 kN Shear resistance, F^ = 361.6 kN For further ...
6) Apron feeders always need variable speed drive. So, maximum of variable speed range should correspond to design capacity, which could be about 20% more than the guaranteed capacity. That means apron feeder will normally run below maximum range by certain margin. This provides room for selection of speed during field trials / setting.
apron and belt feeders operate in harsh environments, where they face both high starting torque and frequent load spikes. Smarter handling of starting torque When sizing feeder drives, a major factor is the necessary starting torque. High shear force increases starting torque compared to running torque, often by more than on apron feeders ...
