Three-Drum Dryer

Introduction:Three-cylinder dryer is also called three-drum dryer, enjoys the today's Germany advanced technology. Three-drum drying machine is combined of three concentric cylinders with different diameters in certain mathematical relationships and structure.

Three-Drum Dryer Overview

Three-cylinder dryer is also called three-drum dryer, enjoys the today's Germany advanced technology. Three-drum drying machine is combined of three concentric cylinders with different diameters in certain mathematical relationships and structure, so its applicable to energy saving drying of all kinds of powder, granular, strip, and bulk materials, such as sand, quartz sand, clay, copper shavings, iron scraps, aluminum shavings, wood chips, leaves, mineral powder, mineral grain size, magnetic powder, carbon granules, tea residue, granulation fertilizer, chicken manure and so on.

Three-drum dryer or three-cylinder dyer mainly used to dry granular materials with certain humidity and particle size, such as yellow sand, foundry sand, slag, coal cinder, clay with small particle size and other granular materials that resist to high temperature, dust and smoke. Moisture content of materials after drying can reach 1 to 0.5 % or below. It is one of the wet materials drying equipment, which is highly efficient and energy-saving product improved on the basis of single-cylinder rotary dryer.


After application of various enterprises and industries, three-drum dryer has achieved good results and well received by various customers. Three-drum dryer has improved internal structure of monocular dryer, which prolongs the time of pre-drying of wet materials and wet materials in the machine, thus improving 50% to 80% of production capacity compared with original monocular dryer.

Three-drum dryer Main feature

Three-drum dryer has compact structure and covers a small area which is half of the single drum dryer does. The three-drum dryer works reliably with low energy consumption and high heat efficiency which realizes good material drying effect, simple automation control and few operating staff.


Three-drum dryer has such advantages as compact structure, simple structure, reasonable layout, etc, which can improve heat exchange rate of materials and thermal energy and make materials drying effect better. What's more, it has low basic investment, which is 1/2 of monocular dryer with same output. Meanwhile, three-drum dryer easily realizes automatic control and reduces operators, which saves labor resources.
