The invention discloses a double-rotor mechanism capable of adjusting the particle size distribution of finished products, which comprises a transmission shaft, an inner rotor, an inner blade, an outer rotor, and an outer blade; The rotors are connected, and the rotation direction of the inner rotor is the same as that of the transmission shaft; the outer rotor is an internal gear structure, and the transmission shaft is an external gear transmission structure. The direction is opposite to the drive shaft; the inner and outer blades are willow-shaped blades. The invention can realize the adjustment of product particle size distribution, make the particle size cut more clearly, increase the service life of blades, optimize product performance, reduce material sorting resistance, save sorting energy consumption, and benefit the energy saving and emission reduction of the grinding system.
Description
technical field [0001] The invention belongs to the technical field of sorting, in particular to a double-rotor mechanism capable of adjusting the particle size distribution of finished products and its application. Background technique [0002] The grading of cement particles has a great influence on the performance of cement. According to Zhang Xiaofeng's research, among all the particles that make up cement, the particles of 3-30 μm play a leading role in the increase of cement strength, and the total content should not be less than 65%. The particles between them are more important to the cement strength, and the more they are contained, the better. The hydration rate of fine particles <3μm is very fast, and some of them are even completed during the stirring process, so these fine particles are only beneficial to the early strength of cement. The degree of hydration of particles of 30-60 μm is low, while the activity of coarse particles larger than 60 μm is very sma...
