Conveyor Units Schematic representation of the modular system:

Central Conveying Systems A perfect modular system The KOCH modular system is your guarantee for the future The KOCH modular system works like this: everything fits together, every piece of equipment is a complement to another. The simplicity of handling is also compelling: conveyor bonnets that fold back, a conveyor that can swivel through 360° and a moveable dosing station − and all without tools. In order to be genuinely successful, it is essential that a company can adapt its technology flexibly to the demands of the market. Flexibility in terms of the KOCH modular system means combining,...

Conveyor Units Volumetric chamber dosing (patented by KOCH) With the KOCH dosing devices it is possible to dosing material with an accuracy of up to 0.01 %. You can colour shotweights from 1 to 5000 grams and this – if required – using just one dosing station. Dosing masterbatch and grains with ± 0.15 % accuracy Each chamber must be filled equally before it is emptied. Any excess grains on the feed roller are scraped off. At a constant speed, it is possible to achieve extremely accurate doses. For example: a feed roller for dosing − for shot weights of 5 grams up to 300 grams. The range of feed...

Central Conveying Systems Most accurate dosing with a cellular wheel A cellular wheel made from V 2 A with large chambers is used for coarse granulate or ground material. Each chamber is filled equally before it is emptied. Excess granulate is scraped off. The cellular wheel made from V 2 A (highest-quality stainless steel) is for throughputs up to 10.000 grams The relevant single feed rollers or alternatively dosing rollers with two offset chambers are available for the following shot weights. 2 to 80 grams 5 to 300 grams 10 to 500 grams 20 to 2000 grams 100 to 10000 grams roller 9/0 roller...
