This plant is suitable for processing dry feed ingredients without molasses. Selected size of grinder is installed on platform of height 34" above floor level and vertical mixer is installed in front of grinder. Feed ingredient after weighing to the required ratio as per the capacity per batch of vertical feed mixer are fed to the grinder manually and ground materials coming out of grinder are taken directly to the intake hopper of mixer which lift the materials to its mixing chamber. Non grindable ingredients (Marble chips etc.) are fed directly into the mixer manually by second inlet provided for this purpose. When all the materials have reached into the mixer, then final mixing time is given. During final mixing, say 15 minutes, grinder remain shut and during this period preparation of next batch i.e. weighing etc. is done. After mixing time is complete, mixer is emptied by bagging and next batch starts. Raw ingredients may be fed automatically from floor level to intake of grinder by installing another screw conveyor.

Comparison of horizontal with vertical mixer :

Vertical mixers are used for dry mixing only and require less labour, less space and are less costly, but require long mixing time & mixing is not as good as of Horizontal mixer. Horizontal mixers are the ideal mixers having far better mixing and certain percentage of liquid/molasses may also be added.
