Conveyor belts with positive angle (type PL) are often constructed in combination with a horizontally mounted conveyor belt bunker. This conveyor technology is often used to supply production processes where larger production batches are placed in the hopper at once and then fed into the process in doses.
In these cases, the horizontal part of the conveyor is equipped with a hopper according the individual requirements. The material, shape and design of the hopper correspond to the conveying parts. Thus, these hoppers are often equipped with e.g. flaps for quick empty. The outer belt covers at the horizontal bunkers normally have only small or no driver cleats. This is useful for the batching process.
The main benefit of this combination in comparison to a single belt conveyor is that the parts are conveyed more safely and gently. Corresponding sensors check that the horizontal conveyor only runs in case of a "free" transmission area. This reduces rotation of parts in the hopper and thus grants sensitive parts handling. In addition, the cleats on the steep belt part are less strained.
As with all MTF Multi-Tech Conveyors, the belt angle can be adjusted continuously in stages of 0° and 60°. Thereby the tension of the outer belt covers remains constant over the entire angle adjustment range.
