Advantages of Calcium carbonate special dryer using downstream drying
Calcium carbonate special dryer is a common device for dehydrating and drying high-humidity materials. In the drying operation, according to the direction of the hot air flow and the movement of the materials, it can be divided into two methods: downstream drying and counter-current drying. Here, we will briefly understand the advantages of Calcium carbonate special dryer using downstream drying.
1. Calcium carbonate special dryer adopts the downstream drying method, which means that the high humidity material and hot air enter the inside of the dryer cylinder from the same end of the cylinder, so that the temperature difference between the wet material and the hot air just entering it is large. In the process of contact, the moisture in the wet material will quickly evaporate under the action of high temperature, which effectively reduces the heat loss, especially for some materials with high humidity, which has a good drying effect.
2. When we use the Calcium carbonate special dryer to dehydrate and dry high-viscosity materials, the downstream drying method is adopted to quickly exchange heat between the high-temperature hot air and the materials, so that the moisture on the surface of the materials can be quickly removed. Evaporate, effectively reduce the viscosity of the material, and ensure the smooth progress of the drying operation. At the same time, in the process of drying some combustible materials such as coal slime, it can also effectively prevent high-temperature gas from directly contacting the materials, reducing the occurrence of safety failures.
3. When using the Calcium carbonate special dryer that dries downstream, after drying the material, the temperature of the material is lower, and a belt conveyor can be used to meet the needs of conveying materials. So, does the Calcium carbonate special dryer use the downstream drying method? The conveying equipment required is simple and common.
4. The Calcium carbonate special dryer adopts a downstream drying method. The negative pressure at the hot end is relatively low, which can effectively reduce the cold air entering the cylinder, thereby ensuring the sufficient heat and temperature of the drying cylinder. Stability is more conducive to the efficient and high-quality drying operation.
