In the dry mortar production line, automated weighing is the batching system is the core unit, raw materials through the screw conveyor to the measuring hopper, in the wall putty production line is also used in this weighing batching system.
The main raw materials such as cement, fly ash, heavy calcium, sand, gypsum, etc. are stored in the silo, and the screw conveyor is installed at the bottom of the silo, and the plc automation control system transmits the signal to the screw conveyor.
This is a typical additive automatic dosage system, for example, in the recipe, 500kg of cement, 300kg of sand, 200kg of heavy calcium,the plc control system informs the screw conveyor to turn on, and when the weight of cement reaches the target value, the screw conveyor for cement stops. After a delay of a few seconds, the screw for sand is turned on and so on until the recipe is completed.
In the wall putty production line, its working principle is the same as that of the dry mortar production line, which belongs to the additive dosing system. This kind of batching system is stable and reliable, raw material A, raw material B and raw material C are added to the dosing hopper in order.
