Description
North Korea Hwanghainam Road mechanical shaft kiln cement production line is a project done by Global Heavy Industry in 2011, with an annual capacity of 100,000 tons, which is a small and medium-sized dry process cement production case, and the entire production from process design, cement equipment production, cement machinery and equipment installation to achieve a turnkey project. The preheating process of the new mechanical shaft kiln is reasonable, the heat loss is less, and the discharge temperature can be controlled within the ambient temperature of +60℃, so the thermal principle is reasonable. The deficiency of the traditional shaft kiln is the problem of poor combustion conditions.

Process
Generally speaking, the mixed type shaft kiln using artificial feeding and discharging is called ordinary shaft kiln. Now, the use of mechanical feeding, artificial distribution and discharge of semi-mechanized mixing type shaft kiln is also counted as ordinary shaft kiln.
North Korea cement production line mechanical shaft kiln
Shaft kiln as a low-speed rotating steel circular cylinder lined with refractory material, used for calcining cement clinker equipment. It is placed on several pairs of supporting wheels with a certain inclination, and is driven by a motor or hydraulic drive to make the cylinder rotate within a certain speed range. Raw material is fed from the high end (kiln end) and moves towards the low end (kiln head). The fuel is blown in from the low end, creating a flame that burns the raw material to the mature material.

In the 33 years from 1973 to 2005, the output of shaft kiln cement has exceeded that of rotary kiln cement. In the past, shaft kiln cement was only used as a supplement to rotary kiln cement, and at this time, shaft kiln cement has played a pivotal role in the cement output structure, and it is also because of the mature technical experience in the production and installation of shaft kiln.
Advantage
North Korea Hwanghainam Province choose shaft kiln
First, considering the small investment in cement plant construction, short construction period, simple process, extensive management, and do not worry about the market, profitable, so spawned a large number of shaft kiln cement enterprise construction.
Second, the shaft kiln cement industry has low access threshold, fast administrative approval, and few supervision links, and at that time, the cement supply was in short supply, the gap was very large, and it became a tight commodity, and there was a huge market demand.
Third, Global Heavy Industry based on cement machinery and equipment for 30 years, in the shaft kiln cement technological progress, quality improvement and price competitiveness advantages, also promoted its rapid development.
