How to choose a practical gypsum dryer

How to choose a practical gypsum dryer
With the emergence of a large number of new materials and the continuous expansion of the application field of drying technology, the dryer equipment will have more and more broad application prospects. Common dryer equipment mainly includes rotary dryer, rotary drum dryer, industrial dryer, high-efficiency dryer (for example: heat pump dryer) and so on. So how to choose a suitable dryer equipment in the actual drying process? For users, this is a tough question.
Although there are many types of dryer equipment, it is difficult to choose a model suitable for your own use. When choosing equipment, you should pay special attention to the model of the equipment, the requirements for materials, and the drying you need. The material and the practical energy-saving effect of the drying equipment are considered together, which not only meets the needs of the work, but also improves the production efficiency. From the details, we can implement the following ten points:
Point 1. Physical properties of materials, such as drying properties of materials to be dried.
Point 2. Physical and chemical properties: water content, particle size, viscosity, flammability, deformability, smashability, etc. must be considered.

Point three, the commodity value of the material and the influence of the drying effect on the equipment. From the perspective of drying capacity, cost-effectiveness, economic benefits, vision planning, and environmental aspects, rationally choose the dryer equipment that suits your needs.
The fourth point is the degree of requirement for the material recovery rate. The drying curve under the proposed drying conditions, the critical moisture content and the equilibrium moisture content.
Point 5. The previous drying method of the material or a similar drying method is a prerequisite factor for reference. At the same time, attention should also be paid to the upper and lower processes of the material drying project, which involves the state method of feeding and discharging of the dryer.
Sixth point, environmental protection issues. Restrictions on dust emission, noise, vibration and other conditions.
Point 7. The operator level and maintenance ability of the relevant users. When problems occur during use, whether the after-sales service personnel of the dryer manufacturer can take corresponding measures within a time.
Point 8. Are there any special requirements for the local annual average temperature and humidity changes and the size of the unit installation site.
Point 9. Available energy sources (coal, electricity, natural gas, liquefied gas, coal gas, etc.) and relevant energy policies and subsidy policies implemented.
Point ten, the comprehensive strength of dryer equipment manufacturers. Dryer equipment belongs to non-standard equipment, the technical content is relatively low, and the profit is slightly higher than other stereotyped equipment, which is the reason why many manufacturers in my country are engaged in the manufacture of dryers.
