Overview
Weight loss scale is a weighing device that intermittently feeds and continuously discharges materials. Due to the fact that the loss control is carried out in the hopper, it can achieve high control accuracy, and the structure is easy to seal. Therefore, it is a major improvement compared to using a spiral scale in powder control. Suitable for controlling the batching of materials such as cement, lime powder, coal powder, liquids, etc. The material output can be spiral, belt or adjustable solenoid valve.
Product Details
Weightless scaleWeigh the complete feeding system (bin, feeder, and bulk materials) through a static scale and control the discharge flow of bulk materials through a variable speed motor or electric shaker. The material is unloaded from the system (through a spiral, vibrating tube, or groove), and the "weight loss" measured per unit time (dv/dt) is compared with the required feeding amount (preset value). The difference between the actual (measured) flow rate and the expected (preset) flow rate will be corrected by a feeding controller, which can automatically adjust the feeding speed to maintain the correct feeding amount without process lag. When the weight measured in the silo reaches the low level of the silo (re feeding), the controller will control the feeding system to feed according to the volume, and then the silo will quickly reload (manually or automatically), and the weight loss controller will restart. In the batch weighing weight loss system, the design is similar to that of the continuous weight loss system, however, the accuracy of the final weight of the feeding (batch) cycle # is higher than the actual feeding amount control. The controller completes fast feeding by providing a high feeding signal to the variable speed drive, and then switches to a low feeding control signal for accurate control at the end of the batch.
Main technical parameters:
Technical indicators:
System measurement accuracy ≤ 0.5%
System ingredient accuracy ≤ 0.5%
The range of ingredient metering control is 0.01-300t/h
Scope of application: Continuous stabilized soil, concrete mixing plant, cement batching sintering quantitative control feeding, coal powder quantitative control feeding, and various concentrated slurry batching.
The weightlessness feeder consists of a hopper, feeders (single and double axis spiral feeders), weighing system, and regulator. During operation, the hopper, material, and feeder are continuously weighed together. After the material is sent out, measure the actual weight loss rate and compare it with the required weight loss rate (set value). Automatically correct deviations from the set point by adjusting the feeder rate. Thus, the material can be fed uniformly and accurately continuously.
Powder scale: solves the problem of feeding measurement and feeding with poor fluidity;
Granular scale: solves any possible bridging problem
