Raw material gravimetric blender equipment generally puts several auxiliary raw materials and main raw materials into the mixer at a certain ratio at the same time, and then stirs them evenly. The key to measurement is the word “accurate”. The measurement method generally adopts the weighing type measurement method.
The action steps of the gravimetric blender are briefly described as follows:
1) Store each storage tank of the machine with various raw materials, and then set the ratio according to the production demand;
2) When the valve of No. 1 barrel is opened, the raw material will be metered and fed into the metering barrel according to the set ratio parameters;
3) The valve of No. 1 barrel will automatically close after the metering is completed, and then the valve of No. 2 barrel will open;
4) The metering and feeding principles of the rest of the barrels are the same;
5) The total weight of delivered raw materials will be displayed on the screen of the controller, and the measurement action of this batch is completed;
6) Then the stirring motor is turned on to stir the raw materials evenly, and at the same time, the weighing chamber starts to add.
7) After fully stirring evenly, the material valve is opened, and the raw material enters the equipment outlet.
When the material level gauge detects a material shortage signal, the valve of the weighing bin of the gravimetric blender is opened, and the material is discharged into the mixing chamber, and the agitator starts to stir. After a certain period of time, the stirring is stopped, the stop valve is opened, and the material is discharged into the next link; The blocking valve is closed, the weighing bin is discharged, and the next cycle is entered; if the material level gauge detects that there is material, the weighing bin valve does not open.
