Overview:
This machine boasts innovative technology, rational design, compact structure, wide application range, high production capacity, excellent product quality, and high efficiency. It saves energy consumption, dries, crushes, and sieves in one unit, eliminating environmental pollution, and the overall performance meets the industry's technical standards.
Principle:
Hot air enters the mixing and crushing drying chamber from the bottom of the dryer through the inlet pipe at an appropriate spray velocity, exerting strong shearing, blowing, and rotational forces on the material. This results in the material being micropulverized through centrifugal force, shearing, collision, and friction, enhancing mass and heat transfer. At the bottom of the dryer, large wet particle clusters are mechanically broken down by the agitator. The particles with low moisture content and small particle size are carried upwards by the swirling air flow, further drying as they ascend. Due to the rotational flow of the gas-solid phases, the inertia of the solid phase is greater than that of the gas phase, causing an increase in the relative velocity between the solid and gas phases, which strengthens the mass and heat transfer between the two phases. Therefore, the machine has a high production intensity.
Features:
Multiple dosing units available for selection, with continuous and stable dosing without bridging during the process.
● The dryer bottom is equipped with a special cooling device, preventing material from deteriorating in the high-temperature area at the bottom.
Special pressure-sealed devices and bearing cooling systems, extending the service life of the transmission section.
● Special wind guide device reduces equipment resistance and provides the dryer's air handling capacity.
● The drying chamber is equipped with grading rings and swirl plates, allowing for adjustable particle fineness and final moisture content (e.g., the final moisture content of calcium carbonate can be adjusted to ≤0.1%).
Compared to other drying methods, it can increase the material density.
● High circumferential air velocity in the drying room, short material residence time, prevents material from sticking to the walls and thermal-sensitive material from deteriorating, achieving fast, small equipment, and large-scale production.
