Weighing Scale Mixer

Gravimetric Blenders Equipment principle

There are four kinds of raw materials 1, 2, 3, 4 in the four storage hoppers. When the blender starts to work, the pneumatic material valve of material 1 opens and material 1 falls into the weighing hopper; when the electronic scale sensor in the weighing hopper senses that the weight reaches the preset value , Material 1 pneumatic material valve closes, then material 2 valve opens, so goes for 4 cycles. 
When the 4 materials fall into the weighing hopper, and the weight reaches the preset value, the valve of the weighing hopper opens, the raw materials fall into the mixing chamber, and the mixing starts, when all the raw materials in the weighing hopper fall into the mixing chamber, the weighing hopper valve closes, the mixing blade continues to mix for a while until all materials are well mixed, and then the valve of the mixing chamber opens, the mixture falls into the storage tank or the molding machine, such a work cycle is completed.
