Dosers provide simple additive metering but rely solely on the machine screw to mix the ingredients.
Pre-mixers mount between the dosing device and the machine throat to thoroughly mix the ingredients prior to processing.
Dosing or additive feeding devices typically do not include a suitable method of actually blending the mixture of ingredients. They rely on the mixing action of the processing machine screw to assure homogeneity of all the materials being joined. So a popular option to ensure a suitable mix is a machine mounted mixer to tumble the ingredients prior to entry into the processing machine.
These throat-mounted devices are very similar to the mixing chambers incorporated into automatic blenders, but operate independently to tumble materials together as they pass through to the process.
Available in a range of sizes to accommodate not only processing thru-put but also the scale of the equipment mounted to them, better models incorporate features for performance, strength, safety and convenience.
Stainless steel material contact surfaces
Baffle plate(s) to create a void for the introduction of additives and to reduce ‘head pressure’ above the processing screw.
Engineered blade and mixing chamber design for maximum material movement, superior blending performance and minimal strain on the mixing motor.
Easy cleanout with easy access door(s) and easily removed components, complete with safety interlocks.
Visibility, via viewing window(s)
Large, strong mounting plates on top and bottom for ease of installation and use with a wide range of equipment.
Machine mounted mixers are a must for older processing machines with unsatisfactory mixing action in their screws. Selection of the proper machine mixer ensures a homogenous blend and coloring is more efficient, more thorough and more uniform. Color consistency of the finished product is improved and problems such as streaking are virtually eliminated.
