ProRate™ Gravimetric Continuous Blenders Flyer

Source: Coperion K-Tron

K-Tron ProRate™/Gravimetric blenders consist of one to eight ingredient feeders and a microprocessor-based controller. They are designed to continuously meter raw materials accurately into a central station hopper. Each of the feeders operate in an independent, continuous loss-in-weight scaling mode to insure accuracy of each ingredient. The desired feed rate for each material can be entered in as pounds (or kgs.) per hour, as a percent of the total rate, or as a percent of the virgin material.
