The choice of the model of the wood sawdust rotary drum dryer is determined according to the evaporation amount, and the confirmation of the evaporation amount is determined according to the original moisture of the material and the moisture after drying. Therefore, the choice of wood sawdust rotary drum dryer model needs to clarify three conditions:
1. The original moisture of the material.
2. The moisture of the material after drying.
3. Production requirements after drying.
For example, the original moisture of wood sawdust is 50%, and the moisture of wood sawdust after drying is 20%. The required yield after drying is 1 ton per hour. In this way, the evaporation can be calculated as: 1000kg/100%- (50%-30%) -1000kg=428KG. According to the evaporation of 428kg of water per hour, the heat required is 342400KCAL. The dryer to be configured is 1.8 meters in diameter and 18 meters in length.
Conclusion: When we choose the model of wood sawdust rotary drum dryer, we must clarify 3 requirements:
1. Original moisture of the material.
2. Moisture of the material after drying.
3. Production requirements after drying.
Then the evaporation amount is calculated according to the law of conservation of energy to determine the model of the wood sawdust rotary drum dryer. Every kilogram of water evaporates requires a fixed amount of heat, so we must obey the law of conservation of energy and not listen to any low-energy, high-yield propaganda.
