About Tschritter
At its Dorfprozelten site, Alfons Tschritter GmbH develops and manufactures devices and systems for the dosing, conveying and material logistics of plastics. The product range includes gravimetric batch dosing units for plastic granulates, additives and regrind up to 700 kg/h, volumetric roller dosing units for powders and masterbatches, conveying units for vacuum conveying systems, rotary tube diversors for fully automatic material changeover, as well as side channel blowers and claw vacuum pumps. The devices are predominantly made of stainless steel and aluminium; custom designs are also part of the offering. In addition, the company provides engineering, installation, commissioning and training. The products are used worldwide in more than 47 countries on 4 continents.
