JGC-50 Heavy-duty weighing feeder. JGC-50 heavy-duty weighing feeder is specially designed to meet the requirements of heavy industry,It can be used with an open loop belt drive to gravimetrically measure the flow of material, or with closed loop control to operate as a feeder and regulate the flow to a constant or dynamic set point.

An accurate and reliable method for sensing belt speed is to measure the belt drive motor speed and directly correlate this to belt speed. The correlation can be made by directly measuring belt speed, with the use of precision optical switches placed over the weigh plane, during calibration of the gravimetric feeder.
Weigh Feeder models cater for bulk materials feed rates from 1kg to 5,000 tph and deliver weighing accuracy 0.5% and better. Weigh Feeders are commonly used to control bulk material flow rate of into a process or to blend products on a continuous basis.
Coal Feeder. It is mainly coal equipment in thermal power Plant pulverizing system. In full closed state, it can not only uniformly, continuously coal, but furnace measurement and it is an ideal equipment which can achieve positive balance calculation coal consumption.

Gravimetric Feeder Principle. 1. The gravimetric feeder weighs material on a length of belt between two fixed rollers using a weighing roller. 2. Belt speed is determined by a tachometer attached to the motor shaft. A microprocessor multiplies the speed and weight signal to arrive at the feeder output. 3.
Thayer Scale has the most comprehensive line of weigh belt feeders on the market today; we are the only vendor to offer inclined or declined weigh belts as part of our standard offering. We design our belt feeders to handle a variety of materials (e.g., plastics, coal, metals, wood chips) and feed ranges (from 30 pounds/hour to 3,000 tons/hour).
The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.

rate. By adjusting the feeder’s weight span setting the linearity curve is rotated so that perfect correspondence between set and measured rate can be established at any given point (e. g. 90% full scale for line B, or 50% full scale for line C). The user will ultimately determine the appropriate frequen-cy of calibration checks based on ...
Oct 12, 1982· The weighing roller thus carries a predetermined portion of the weight of coal on the weighing span and the weight carried thereby is sensed by a weight-sensing mechanism including, for example, load cells of the type readily obtainable from commercial sources.
