SKW-E

6.2.1.1. Conveying ratio

The conveying ratio between component 1 (= regrind) and component 2 (= virgin material) can be freely selected.

The control setting refers to the conveying time of component 1 (= regrind).

The conveying time of component 1 can be set from 0 to 99 % of total conveying time.

Example

Proportioning valve setting: 22 %

Conveying ratio: 22 % component 1 and 78 % component 2

&

Conveying ratio relates to conveying time, not to the amount of material conveyed.

6.2.1.2. Switching cycles

During each switching cycle, the SKW-E switches back and forth one time. The pre-set conveying ratio is not affected by this. In order to prevent strong formation of layers in the conveyed material, the number of switching cycles per conveying procedure can be freely selected. Setting takes pla- ce by entry of one cycle period. The cycle period can be set between 5 and 50 seconds. The set- ting is carried out in five seconds.

The cycle period may not be longer than the conveying time.

The shorter the cycle period, the higher the number of switching cycles.

The higher the number of switching cycles, the less significant is the zo- ning effect in the hopper loader.
