The BTL is applied to the material feeding and measurement for NSP cement production line. The system is composed of screw brake, inflated valve for material dispart, pneumatic switch valve, electric flow rate valve, Coriolis flowmeter. This system is characterized with stable feeding, accurate dosing, quick adjustment, zero point self correction, on-line automatic calibration etc.  The performance of the system in dosing indicated that the system can widely substitute the importation, and the application to the dosing of raw material with 125-250 t/h come true.
