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.

5. Special alloy is used for rotor••,sealing plate anddischarging head to ensure the equipment service life.

6. The three functions such as pulverized coalquantitative feeding, metering and air locking are integratedin one. It is characterized with compact structure and smallspace, thus reducing infrastructure investment.The mechanicalstructure is simple, with easy maintenance, which doesn't needspecial tools or hoisting device.
