The variable frequency batching machine can achieve the metering, proportioning and conveying of various materials. The metering and proportioning process can be fully automated. Each batching tank is equipped with an independent weighing module and Feeding machine. Through metering equipment such as combination valves, double butterfly valves, translation valves, metering screws and Weighing modules, the purpose of precise batching is achieved. According to the production formula requirements, the production control application program needs the corresponding silo screw conveyor for each type of material to discharge materials respectively. The changes in the weight of the scale hopper are collected by the computer. When the required material quantity reaches the set value, the next material configuration is transferred. When all the materials have been prepared, the batching process is completed. However, if there is no material in the mixer and the mixer door is tightly closed, when the main unit of the mixer is working, open the scale hopper door, and the material will fall into the mixer and enter the mixing process. If it is necessary to add and trace components, they will be activated separately. They can be added automatically or give warning prompts. When the mixing reaches the set mixing time, the mixer door will be opened and the timer will start automatically, then the discharging process of the mixer will begin. Set the door opening time according to the discharge speed of the mixer. When the set door opening time is reached, close the mixer door. In this way, an automatic batching process is completed.

This variable frequency batching machine mainly realizes the batching through the DCS control system. When the liquid level in its mixing tank meets the production requirements of the beneficiation plant, it automatically pre-starts the mixing tank. After the pre-set start-up time requirement is reached, the liquid transfer pump (one in use and one on standby) starts to transfer the liquid to the liquid storage tank, keeping the liquid level in the storage tank at a certain level. At the same time, when the main transfer pump malfunctions, the standby transfer pump will be automatically switched and started under permitted conditions to complete the liquid preparation work. This system needs to form a first-level interlock between the liquid level in the storage tank and the liquid transfer pump, and then form a second-level interlock between the liquid transfer pump and the liquid stirring tank. To prevent the problem of liquid overflow caused by the malfunction of the storage liquid level gauge or the situation where the pump runs idle due to the lack of liquid in the stirring tank, first, a procedure for judging the integrity of the liquid level gauge in the liquid storage tank is added. After the liquid transfer pump has been running for a period of time, the pump will automatically stop if the liquid level in the storage tank does not change. Second, the running time of the transfer pump is used as an indirect judgment. After the pump has been running for a relatively long time, Automatic pump stop.
