Transfer Chutes
Transfer stations often have a rock box, which is a lip around the bottom of the chute that provides a ledge for rocks and dust to collect. The purpose of a rock box is to prevent the flow of ore from wearing out the bottom of the transfer chute. TRANSFER CHUTES OVERVIEW. Transfer chutes are primarily used at the transfer points in a conveyor ...
Dilute or Dense Phase Pneumatic Conveying? | AIChE
Dilute phase also refers to the lean solids loading within the conveying line. Typically, a dilute phase line conveys less than 15 lb (~7 kg) of solids per pound (~0.5 kg) of gas at a pressure of less than 15 psig (~1 barg). Dense phase. This occurs when particles are conveyed in the gas stream at a velocity that is less than the saltation ...

22 engineered Flow Chutes
Engineered chutes typically employ a design called "hood and spoon" transfer. This design is composed of a "hood" dis-charge chute, at the top of the system, and a "spoon" receiving chute, which places the material onto the belt being loaded. The hood and spoon are typically installed as a pair, although a particular material-han-

Copper, iron and other hard rock mineral ores utilize the rock box principle to control the flow of primary crushed ore in the transfer chute, typically -200 mm open side setting.
Design Considerations of the Transfer Chute | Martin Engineering
Head pulley diameter and face width help determine the width and height of the head chute. The space between the chutewall and the pulley rim should be small enough that large lumps are not able to pass from the carrying side to the return and are not caught between the pulley and the chutewall. A typical space is 50 to 75 millimeters (2 to 3 ...
