by employing a feeder conveyor, the conveyor belt now has a 45 degree trough angle along the entire conveyor route, with the only chutes being in the storage bin discharge area. as with a belt feeder, the contour of the material to be conveyed is specified by a shear gate and the flow of discharged material is defined by varying the conveying speed.
belt flap can cause conveyor component damage and spill-age. determining idler spacing versus belt tension for particu-lar idler roll diameters and speeds during the design period is beneficial in avoiding problems and the need for retrofitting counter measures. the 20km curragh north overland conveyor
properly tracking a conveyor belt seems to be an issue in most bulk material handling operations. a mistracked belt will prematurely damage, cause material spillage, and put a strain on limited resources to address the problem. this webinar will discuss the correct strategies to keep the belt running straight.

the hinged steel fastener can be used on all conveyor belts from 1/4″ to 5/8″ thick, and allows the joining of belts of varying thicknesses. riv-nail fasteners a design pattern composed of two to eight riv-nails allows for the fasteners to be clinched for maximum pull-out resistance — as the pilot nails do not cut the fabric, but divide it, and allow the rivets to slide between fill and warp yarns.

the first step in the design of a belt conveyor with a specified conveyor capacity is to determine the speed and width of the belt. the magnitude of the belt speed can be determined using: equation. where: c = conveyor capacity r = material density (kg/m3) v = belt speed (m/s) a = conveyor’s belt cross-sectional area belt speed should be specified such that it does not cause spillage of the raw
by comparison, belt conveyors only use about 20% and screw conveyors only use about 45%. this means drag chain conveyors can move a greater volume of material in a smaller housing, at slower speeds, and with less horsepower. slower chain speed means less wear, and less horsepower equals lower energy requirements and operating costs.
