Double-rotor mechanism capable of adjusting grain size distribution of finished product and application of double-rotor mechanism

Abstract

The invention discloses a double-rotor mechanism capable of adjusting grain size distribution of a finished product. The double-rotor mechanism comprises a transmission shaft, an inner rotor, inner blades, an outer rotor and outer blades; the inner rotor and the outer rotor are coaxially arranged; the lower part of the transmission shaft is connected with the inner rotor through a pull rod support; the rotation direction of the inner rotor is the same as that of the transmission shaft; the outer rotor is of an inner gear structure, the transmission shaft is of an outer tooth transmission structure, the outer rotor is connected with the transmission shaft through a plurality of transmission gears, the transmission shaft drives the outer rotor to rotate, and the rotation direction of the outer rotor is opposite to that of the transmission shaft; and the inner blades and the outer blades are willow-leaf-shaped blades. According to the double-rotor mechanism, the grain size distribution of the product can be adjusted, so that grain size cutting is clearer, the service life of the blades is prolonged, the product performance is optimized, the material sorting resistance is reduced, the sorting energy consumption is saved, and energy conservation and emission reduction of a grinding system are facilitated.

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...
