Amid the dynamic mass technical innovation movement, the Sangwon Cement Complex established a technique of producing high-quality cement by relying on its own efforts, technology and locally-available materials and fuels.

The complex solved many technical problems including the selection of suitable raw materials and the fixing of proper mixing ratios and grain component in order to establish the technique of making high-quality cement for various uses, which conforms to international standards and technical requirements, with the existing equipment.

It also provided itself with a large quantity of reserves for increased production by applying a low-heat cement production method based on the previously dumped slate.

As it upgraded some processes on an expansion basis, it developed a control program for them by relying on its own technical force.

“Previously, we used to ask professional scientific research and educational institutions to solve key scientific and technological problems arising in production. This time, however, it was impossible to ensure the period of production, so we decided to solve them by our own efforts,” said technician Pyon Wan Ju.

The complex pays attention to enhancing the functions and role of its central control room.

The mission of the room is to monitor and control all the processes ranging from the pulverizing and baking of raw materials to the crushing and carrying in and out of cement and coal.

According to its chief Jon Myong Il, given that all the meters, machines and automation elements are operated according to the command of the room, if controllers have no full understanding of the processes in charge, it will be impossible to maximize the quality and quantity of overall cement production. He added that the room gives priority to the improvement of their technical knowledge and skills.

They make positive efforts to find out an operation method for fixing the numerical values in controlling processes and thus ensuring their full capacity.
