1. lt directly measures material weight inside the rotor,whose metering accuracy is accurate and will not be influencedby material property, air flow and material flow properties.

2.The device and the coal-conveying Roots fan weoffered is the whole system which leaves out the air-lock devicesuch as the screw pump. The pressure variation of Rootsfan will not influence the coal feeding amount and meteringaccuracy,which is good to stabilize the kiln thermal regulation,lengthen the refractory brick life,reduce energy consumptionand improve clinker quality.

3. lt combines discharging by gravity and injection bycompressed air (Invention patent, patent No. ZL201510658840.1), which couldeliminate effectively the influence of bin pressure and avoidmaterial surging. The air injection device could avoid pulverizedcoal arching and blockage to make the pulverized coal alwaysunder loose condition, with a certain density.

4. lt adopts the predictive control technology,whichsaves in the control system the rotor load and its angulardisplacement at any time. Before the pulverized coal isdischarged,the rotor load has been known.The angular speedduring material discharging is calculated on the basis of thesystem set flow rate and rotor load. In controlling the speedof frequency variable motor, we can realize quantitative coalfeeding.

2. The steady flow bin structure is used to ensure pulverized coal fluidity within the bin, thus forming funnel effect, meanwhile wall sticking of pulverized coal in the steady flow bin can be avoided in combination with thermal insulation and negative pressure suction auxiliary discharge technology (nation patent).

3. Wide joint is designed to avoid wall sticking of pulverized coal. There is the blender in the feeder to make materials fully fluidized, avoid wall sticking and eliminate material dead area, thus helping discharge smoothly.

4. The material level of steady flow bin is controlled in real time according to the actual technological requirement for the plant. The steady flow bin is set at the proper bin level to ensure stable and continuous coal feeding. The material calibration is regularly made to ensure long-time stable metering accuracy.
