·When design a sub structure for an apron feeder there are certain factors that must be considered First there are three types of loads Dead load live load operating and live load start up Also to prevent maintenance of clearing spillage under the feeder a dribble chute or scavenger dribble conveyor should be incorporated
The purpose of this paper is to focus on these aspects indicating the basic principles of chute design with particular regard to feeding and transfer in belt conveying operations 2 BOUNDARY FRICTION COHESION AND ADHESION 2 Boundary or Wall Yield Locus For chute design wall or boundary surface friction has the major influence
Transfer Chute Design Transfer chutes are used in bulk handling systems to perform a variety of operations For instance accelerating the bulk material from a slow moving belt or apron feeder onto a conveyor or capturing and re directing the flow
·Along with our other vibratory equipment vibratory feeders are great problem solvers Feeders are well known for their ability to move material from point A to point B effectively However a well designed vibratory feeder offers flexibility to the end user and increased safety and efficiency in the process Feeders can range from small base mounted
·Metso Outotec s Crossover feeder fits perfectly in the Feeding solutions portfolio to provide an option where a belt or apron feeder would not be optimal The Crossover feeder provides a modular belt over apron hybrid feeding solution with an innovative design leading to reduction in overall costs without losing productivity
·Areas such as the bottom of the feed chute can also be better protected with an autogenous layer of ore This solution often referred to as a rock box design can extend the life of the chute liner in certain applications Another part of the solution is to design better access points to improve liners replacement times
We offer SIDE WALL CHUTES HANGING WALL CHUTES and BELT FEEDERS In accordance with SANS specification 0208 the chute is designed for a nominal design pressure of 840kPa in platinum mines and 600 kPa in goldmines 840 kPa is equivalent to a 30m ore pass filled with UG2 slurry hydrostatic head

Easily aerated powders require careful attention to feed on transfer chute design with enclosures additional labyrinth type skirting around the inlet and dust take off points Belt feeder calculations require knowledge of the consolidated silo or bin opening pressure for initial bin fill condition as well as flow condition
·Plant Design Hoppers silos or dumping stations require discharge equipment to adapt to the varying flow properties of bulk materials and to the given design criteria The bulk materials behavior during storage and discharge generally depends on the particle size the degree of homogeneity and the moisture content which
·Chute While primarily a flow directing device the chute when properly designed can control the velocity of material entering the belt in a way which It is important that all bin and feeder design problems follow the above procedures When investigating the required bin geometry it should be assumed that gravity will provide a
about chute design chute design considerations for feeding and transfer roberts emeritus professor and director centre for bulk solids and particulate Figure 9 illustrates the application of a gravity feed chute to direct the discharge from a belt or apron feeder to a conveyor belt The bulk solid is assumed to fall vertically through a
·Chute design is a complex process that takes into account many competing objectives and relies heavily on the intuition of an experienced designer to be the origin We will treat point A as the exit of the feeder and point B as the exit of the chute onto the belt The first step in any design process is to develop a model by which various
