Definition and function of grinding teeth slope in grinding rolls?

[Summary description] The grinding roller in the grinding teeth slope is according to the helix planing out of the grinding teeth and the grinding roller roller body bus does not appear parallel degree, usually with the same grinding teeth ends in the roller body end face circumference of the distance and the length of the roller body length of the ratio expressed.

　　Grinding roll in the grinding teeth slope is according to the spiral line planing out of the grinding teeth and grinding roll roller body bus not parallel to the degree, usually with the same grinding teeth at the end of the roller body face circumference of the distance between the roller body length and the roller body length of the ratio expressed.

　　The grinding roll in the grinding teeth slope is the two grinding rolls rotating toward each other on the material to produce cross points, and the key to strip scraping grinding. If there is no slope of the grinding teeth, fast and slow roller teeth will be parallel to each other, in the grinding between the two rollers will be unstable, a wrong meshing phenomenon, which makes it not only easy to cut the bran flakes into silk, at the same time the grinding rollers will also produce vibration and affect the grinding effect. The grinding teeth must not only have a slope but also must be installed correctly.

　　Two rollers grinding teeth in the grinding area on both sides of the relative material form many intersections, when a pair of grinding rollers rotate in the opposite direction, fast rollers grinding teeth and slow rollers grinding teeth will form many intersections, in case of grinding rollers between the roll distance is less than the material to be ground, the material will be in the intersection by the relatively strong shear effect. When the number of intersections in the grinding area is higher, the average chance of the material being sheared in the area will increase, and the crushing capacity of the equipment will be enhanced.

　　In other conditions the same case, the slope is larger, the number of intersections in the grinding area is larger, the material in the grinding area by the degree of crushing will be enhanced, the cortex is easy to break, the product quality is poorer, but the power consumption is lower. So in the processing of hard wheat, old wheat, low moisture wheat and quality requirements of high quality should be selected when a smaller slope. And in the requirements of the lower power consumption can choose a larger slope.
