How to shorten the drying time of sludge?

For sludge drying equipment, shortening the drying time of sludge means improving the production efficiency of the equipment, so how can we reduce the drying time? In fact, there are many factors that affect the drying time, such as: particle size, viscosity, moisture content, and the movement state during drying. In fact, the improvement of these parameters is mostly determined by the drying technology.

High humidity and high viscosity materials need longer drying time than ordinary materials, so it is an effective way to shorten the drying time to control the moisture content of materials. The method of controlling moisture content can be selected as mechanical dehydration method, that is, the water content of materials can be reduced by using dewatering equipment such as filter press and centrifuge, or the way of dry mud back mixing can be selected. This method can improve the heating conditions of materials in the dryer to a large extent, thus effectively shortening the time.

In addition to adjusting the moisture content of the material, the particle size, viscosity and the movement state of the material during drying are also very important for shortening the drying time, so how to do it? Take the "rotary harrow three cylinders multiple-loop" sludge drying treatment equipment as an example, because the main machine is equipped with a "whirlrake crushing" device, the wet materials entering the cylinder are quickly broken into small pieces Particles, and under the function of "guide material and lift material" system, make the sludge particles do high-speed centrifugal movement, showing a "boiling" state, to avoid the sludge sticking together due to the loss of "vitality", solving the drying problem of high humidity and high viscosity materials.

The whole set of equipment uses the automatic control system, which can flexibly control the temperature, wind direction, wind speed and other parameters of the hot air. It is easy to operate, fast in drying speed and high in heat utilization. It is one of the sludge drying equipment with high cost performance.
