How to determine the rotation speed and horizontal inclination of the drum in the food classifier?

The drum classifier in the food classifier is one of the most commonly used classifiers, and its technology has also developed quite maturely. The drum classifier is very widely used in fruit classification. With the continuous development of my country's fruit industry, there are higher requirements for the graded sales of fruits. The determination of the horizontal inclination angle of the specific gravity of the rotating speed of the drum in the drum classifier has an important influence on the quality of fruit classification. So how to determine the drum speed and horizontal inclination angle, let's take a closer look: the determination of the speed n and the horizontal inclination angle a. The drum speed affects the classification efficiency and production capacity, and the drum speed depends on the diameter. The drum is generally placed in an inclined position, and the usual speed can be determined by the following formula: n u003d 12～14 /√R In the calculation of the drum size parameter, the drum diameter Du003d0.60 m, and the speed range in this design can be obtained according to the formula n u003d 12 ～14/√Ru003d12～14/√0.60u003d15～18 r/min and considering that the rotation speed of the drum is generally 10～15 r/min, generally not more than 30 r/min. In combination with actual production requirements, the drum speed nu003d18 r/min is finally determined. It can be seen from the above formula that n is inversely proportional to √R, that is, the larger the diameter of the drum, the smaller the rotation speed. The inclination angle a of the roller is related to the length of the roller, generally about 3 o ~ 5 o, the long roller takes a small value, and the short one takes a large value. The length of the roller in this design is Lu003d2.393 m, and au003d4 o is taken in accordance with the needs of actual production.
