Experimental Study on the Cutting and Crushing Performance of Caragana Korshinskii Strips

Abstract

Due to their characteristics, Caragana Korshinskii bars are prone to be crushed by kneaded crushed material, and the kneaded crushed material is prone to clogging the sieve, thus affecting the crushing effect. In this paper, we use the Caragana Korshinskii special hammer crusher to carry out the Caragana Korshinskii cutting and crushing test to study the influence of Caragana Korshinskii diameter, cutting length, and moisture content on the crushing effect of Caragana Korshinskii, and obtain the best process parameters through the response surface method. The results were as follows: When the diameter of Caragana Korshinskii strips was in the range of 6–9 mm, the length of the cut section was in the range of 4–8 cm, and the moisture content of Caragana Korshinskii strips was in the range of 10–19%, the Caragana Korshinskii strips crushing effect was the best, and the kneading situation was the lowest. The optimal Caragana Korshinskii crushing effect was achieved when the diameter of the Caragana Korshinskiibar was 6.5 mm, the length of the cut section was 8.4 cm, the moisture content was 19%, the sieve rate of 2 mm was 46.15%, the sieve rate of 4 mm was 66.32%, and the length of the kneaded wire was 3.3 cm.
