Proper sizing and selection of your apron feeder
Apron feeders are a volumetric type feeder, which means bulk density is used to determine the speed and power (torque) needed to extract a certain tonnage per hour (tph) of material.

What is an Apron Feeder?. ApronFeeders are mechanical devices used to evenly transfer materials to crushers or other equipment. They are commonly used for feeding primary crushers but also work well in primary, secondary, and tertiary settings as primary feeders, for primary crusher discharge, in stockpiles, at rail unloading stations, and in storage bins.

Apron feeders have capacities up to 6000 t/h and are able to transport materials with ... reason for the inclination is the facilitation of truck discharge and the protection of the equipment when the material will fall directly on it. Speed is limited to 0.25 m/s (0.82 ft/s), and in some cases to 0.4 m/s
Basic criteria that should go into properly sizing an apron feeder should include feed rate (peak and normal), material characteristics (such as moisture, …
Following the publication of the International Mining October issue and, more specifically, the annual in-pit crushing and conveying feature, we have taken a closer look at one of the core elements that …
The various trajectory techniques use varying methods of determining the discharge angle and discharge velocity, Vd, and as a consequence a range of discharge angles results for any given belt speed condition with Korzen (1989) always having the lowest discharge angle and Goodyear (1975) having the largest discharge angle.
Some best practices for an apron feeder's space requirements are for side access, front discharge access and rear access. Side access should be on each side of the apron feeder, and allow access to the top, return rollers and drive system (which should also have additional space around it for a laydown area).
The feeder is one of the most critical parts of the material handling system and must ensure accurate, uniform discharge from storage to the downstream system. There are a wide variety of challenges to be considered in the design of a feeder, and the importance of designing an integrated hopper / feeder solution can not be over emphasised ...
The path the bulk material takes as it is discharged from the delivery conveyor is called the trajectory. Trajectory is affected by the speed of the belt, the angle of inclination of the …
Heavy duty apron belt feeders for mining and industrial application. Complete solutions incorporating bins, hoppers, structures and discharge conveying systems. ... Change in vertical conveying direction, by allowing a bend after the hopper discharge to raise the discharge of the feeder without reducing hopper capacity or raising the hopper height.
Lastly, apron feeders can reclaim a variety of dry or wet materials of various sizes at a uniform rate. This flexibility can be applied in many applications. Advantages of a tractor chain style apron feeder. A tractor chain style apron feeder refers to the undercarriage chain, rollers and tail wheels that are also used in bulldozers and excavators.

Apron feeders are a volumetric type feeder, which means bulk density is used to determine the speed and power (torque) needed to extract a certain tonnage per hour (tph) of material. The minimum bulk density is used to determine the speed and the maximum bulk density establishes the power (torque) needed for the feeder.
