Cement factory increases output over 1.2 times

The Sinwon Cement Factory increased its output over 1.2 times as compared to the same period of last year.

The factory built an alternating-current contactor recycling base to increase its lifespan two times more than before, increased the operational rate of equipment and completed a cement production method based on ultra-anthracite to save lots of raw and other materials. It also invented a new dust collecting device, thus raising the actual yield in the drying process.
