Kim Won Chol, section chief at Pyongyang University of Mechanical Engineering, has gained recognition as an accomplished machine designer.
Until now, he has designed a hydraulic graphite electrode extruder, a line of putting bottles into boxes, an extractor of natural ingredients and other machines and equipment badly needed in different fields of the national economy, thus making a great contribution to the modernization and automation of production lines.
His designs are all featured by full consideration of each factory’s actual production conditions and optimization in terms of manufacturing costs and profits.
In 2022 he took charge of a project for establishing the tile production line at the Pyongyang Ceramic Factory. The line required dozens of machines and tools including a variety of crushers, separators, agitators, mixers and conveyors.
At first, he learned in detail about the production facilities of other tile factories. He started to work out the blueprints of necessary machines that suited the specific conditions of the ceramic factory.
In particular, the diaphragm pump had high technical requirements as it was instrumental in the process of preparing raw materials to produce moulding powder. He studied the types, structures and operational principles of different diaphragm pumps widely available in the world, and came up with a design of a pump suited to the actual conditions of the factory.
The pump could be used as an immersible pump and for other purposes and its structure was so simple that it could be installed and repaired easily.
He also solved problems arising in the design and manufacture of other machines such as transfer conveyor and double screw mixer, making it possible to complete the tile production process.
The more achievements, the more ambitious goals he set.
In the course of this, he was awarded the February 16 Science and Technology Prize and over 60 certificates of inventions and registrations of sci-tech hits, and won the title of October 8 Model Teacher. In 2022 he was nominated as one of the best scientists and technicians in the capital city of Pyongyang.
He helped over 10 students and colleagues earn academic degrees.
Now he is working on projects for machines and equipment conducive to renovating regional-industry factories.
