The device of the batch weighing metering mixing equipment is generally to feed several auxiliary raw materials and main raw materials into the mixing machine at same time according to a certain proportion, and then mix them evenly. The key to metering is the word "accurate". The metering method generally uses the weighing method According to different weighing methods, the working mode of the batch weighing metering mixing equipment can be divided into batch incremental weighing, loss-in-weight weighing and continuous weighing of in the flow process.
The operation steps of the batch weighing metering mixing equipment are described as follows:
1) Fill various raw materials into each storage bucket of machine, and then set the proportion according to the production needs;
2) When the valve of bin No.1 is opened, the raw material will be fed into theering cylinder according to the set proportion parameter;
3) After the valve of bin No.1 completes the metering, it will be closed automatically, and then the valve bin No.2 will be opened;
4) The metering and feeding principle of the rest of the bins is the same;
5) The total weight of the raw material to be delivered will be displayed on the screen of the controller, and the metering action of this batch is completed;
6) Then the stirring motor is turned, the raw materials are evenly mixed, and the weighing bin starts to add materials.
7) After the raw materials are fully and evenly mixed, the material blocking valve is, and the raw materials enter the equipment outlet.
When the level detector detects the missing material signal, the valve of the weighing bin of the batch weighing metering mixing equipment opened, and the material is fed into the mixing bin, the stirrer starts to stir, and after a certain period of time, the stirring is stopped, the material blocking valve opened, and the material is fed into the next link; the material blocking valve is closed, and the material in the weighing bin is discharged, and enters the next cycle; if level detector detects the material, the valve of the weighing bin is not opened.
