The high-temperature air lock valve produced by Portland is a special air lock valve designed to adapt to the blocking of high-temperature gas in the process system. so, the valve is widely used in cement production lines.

       It has compact structure, reliable performance, convenient maintenance and adjustable rotor clearance. The lining of the valve body is made by

 heat treatment process and has good wear resistance. It can effectively prevent the back channeling of high-temperature gas in the kiln during the

 feeding of raw meal into the kiln. Its derivative products are used for unloading and air locking of cyclone dust collectors of various specifications

       Since 1996, Portland has carried out the development of Coriolis powder material metering technology and the production of related products. Relying on the company's comprehensive advantages in cement production process, metering principles, equipment design, automatic control

 methods and other related majors, and a group of experts who have been engaged in cement production process research for a long time, they 

have successfully developed a new generation of large-flow powdery material metering system-cement bulk weighing integrated system, which

 realizes the integration of cement bulk and metering, with a metering accuracy of ±0.5%.

       The application of this integrated system for bulk cement metering can simultaneously complete the load metering during the process of filling

 cement in the bulk truck, which changes the traditional method of loading and metering separately. The system is also suitable for the metering of

 the volume of cement bulk ship carriers.
