Wet sawdust is a waste material with high water content, and direct combustion will cause environmental pollution. The use value of sawdust after drying is greatly increased. It can not only be used to make various boards, but also to make biomass fuel pellets, etc. So which method of drying wet sawdust has the lowest cost?
There are three ways to dry wet sawdust, natural drying, using a sawdust drum dryer, and using a box dryer, so which method is the cheapest?
1. The cost of natural drying is mainly used in time and labor, and it must be adjusted in real time according to weather factors. If the amount of wet sawdust is large, a large open space will be needed, and it will take 2 to 3 days to dry and spread out. Both putting and collecting require some workers and large-scale equipment to operate. Many enterprises do not have the conditions for natural drying, and the time does not allow it.
2. Use a drum-type sawdust dryer, use biomass, coal, steam, etc. as a heat source, and quickly dry the sawdust through the heat generated by combustion. It takes about 30 minutes to dry one ton of sawdust on average, and only one or two workers are needed to operate the whole machine. It is not affected by weather factors and the fuel cost is low.
3. Use a box-type dryer to dry. This drying method mainly uses electricity. A closed thermal energy space is created through air energy equipment to evaporate the moisture in the wood chips in time, but the output is small and the energy consumption is large, not suitable for mass production.
The lowest cost of wet sawdust drying is undoubtedly the drum drying equipment, and different manufacturers, different processing techniques, and different drying techniques will have different costs.
