During the material falling process of the buffer electronic floor scale, the force acting on the hopper can be decomposed into the weight of the material inside the hopper and the impact force of the material flow. The weight of the material is a linear function of time. When the flow integral reaches the weight set value, the motor is turned off. Due to the effect of the overimpact, the flow significantly decreases to zero. When the weighing sensor detects that the material hopper is short of material, The feeding screw motor starts and operates.

The Internet of Things electronic floor scale adopts precise weighing, measurement, data collection, communication, automatic generation of database, automatic generation of label information and inkjet code information, and real-time display of production data, etc. The tilt Angle signal, current velocity, acceleration and total weight are selected as the inputs of the RBF neural network, and the total weight is used as the output value to automatically control the weight range of quantitative batching.

The conveyor belt electronic scale continuously or discretely weighs the materials passing through the weighing platform of the conveyor belt, and performs real-time weighing according to different requirements. It also displays, stores, and implements necessary control. The weighing system integrates several electronic scales with a computer for centralized control. All information is monitored by the upper-level management computer through the communication network, achieving optimal control.

The cooling electronic scale is installed on the cooling tower support. The divider will transfer the high-temperature materials from the conveying belt and scrape the materials down into the cooling tower. The materials are transported vertically from top to bottom through the gap channels between the stainless steel heat transfer plates in a dense-phase manner. During the cooling process, the cooling water circulates within the heat transfer plates. The flow directions of the materials and the cooling medium are in counter-current, which can achieve a higher heat transfer efficiency, thereby reducing the temperature of the cooled materials. After cooling, the materials are weighed and then lifted by the bucket elevator and re-sent to the material conveying belt for further transportation, and then sent to the subsequent process section for measurement.
