2.7.4Additive to regrind

It is possible to dispense more additive in relation to the amount of regrind. Choose for this definition menu (F1) ‘controller / public parameters’. A maximum of two hoppers (additive) can be defined (additiveToRegrindHopper). The definition must be completed defining the requested percentage (additiveToRegrindPerc).

ADDITIVE TO REGRIND

	Not activated		Activated with 2.0%
Component	Recipe	Weight (g)		Recipe	Weight (g)
Regrind	20.0%	400.0		20.0%	400.0
Natural 1	4	1219.0		4	1213.0
Natural 2	1	304.8		1	303.2
Additive	5.0%	76.2		5.0% + 2.0%	83.8

2.7.5Regrind control

The flow of ‘regrind’ is very often not continuous due to the process. There are two methods to adjust the amount of regrind to the actual process: ‘Empty Regrind’ or ‘Stock Silo’.

2.7.5.1Empty regrind Control

Empty regrind control means: keep the regrind-hopper empty. The material must be dispensed, because otherwise another parts of the process can be destroyed (regrind return mechanism).

Through menu (F1) ‘controller / protected parameters’ the process can be activated. After the process is started a defined amount of batches (Empty regrind wait count) must be awaited before the percentage will be increased. The percentage will be increased in

the defined number of steps (Dispensevariation cycl.) until the requested percentage is reached (Dispense increase).

If not enough material can be dispensed from the regrind hopper, then regrind will be reset to the original setting (recipe).
