Several precautions during the operation of commercial sawdust dryer machine

The commercial sawdust dryer machine, also called airflow dryer, are commonly used equipment for a 2-ton daily charcoal production line. Sawdust drying is essential for producing high-quality sawdust charcoal. What issues need to be paid attention to when using a sawdust dryer in order to maximize its working performance? Shuliy charcoal machine manufacturers are here to share with you useful tips.

Why use the sawdust dryer machine for making charcoal?

Sawdust drying is the second process in a charcoal production line. Moisture-qualified raw materials processed by the commercial sawdust dryer machine are a prerequisite for producing high-quality charcoal. Excessive drying of raw materials such as sawdust can cause longitudinal cracks in the extruded forming rods, and even severely cause the forming briquettes to catch fire.

At this time, we can even mix the raw materials into sawdust. Excessive moisture in the raw materials usually causes transverse cracks in the forming rods, accompanied by back-blow air from the hopper, and sounds during sawdust extruder machine operation. In this way, raw materials with large moisture content need to be dried by a dryer.

A qualified sawdust dryer machine has at least the following components: a fuel furnace, a lowering roller, a reduction motor, a number of pipes and elbows containing insulation layers, a fan, and a separator. The sawdust dryer also has certain requirements for the volume of raw materials and generally requires a particle diameter of less than 8mm.

But the size of the raw materials should not be too small, otherwise, the raw materials will easily burn in the pipeline. Most of our foreign customers’ charcoal processing plants use hot air duct dryers. The advantages of this commercial sawdust dryer are direct heating, fast drying speed, foldable installation, and space-saving. The principle is to let the wet raw materials mix with the high-temperature airflow in the pipeline, and finally obtain the raw materials with the required moisture content through the separator.
