Mechanical transport equipment

Index

This comprises conveyor belts, lattices and spiked lattices. Conveyor belts permit high speeds.

They are used as collector belts in mixing batteries or as infeed or horizontal conveyors in openers and hopper feeders. They have the disadvantage that sometimes the material slips on them.

The forwarding effect is often better on lattices (Fig. 67). They are used as horizontal feed lattices and as short transport belts within a machine. They are endless and consist of circulating belts to which closely spaced, individual hardwood crossbars are screwed or riveted. Today’s conveyor belts (Fig. 68) no longer use crossbars. The belts consist of different layers with a fiber-free surface. The belts are driven by shafts that simultaneously serve for belt tensioning. The forwarding speed is usually very low.

Inclined lattices or  spiked lattices (Fig. 13) are the same in terms of structure and drive. However, steel spikes are set at an angle in the crossbars, so that the raw material can be transported upward. Inclined lattices are operated at speeds up to 100 m/min. They usually interact with evener rollers, and thus function mainly as opening devices.
