30%左右。In the course of the study, the radial feeding device of 9R-40 straw rubber was designed and installed. The experimental study on performance of straw rubber was carried out by going through alterring the rotational speed of spindle, the rotational speed of feeding roll and the shape of hammer in feeding mouth. By means of orthogonal experimental analysis, the best parameters of production rate were obtained. The rotational speed of spindle was 2980r/min, the rotational speed of feeding roll was267r/min and the shape of hammer was channel type. Based on the achievement, the production rate of 9R-40 straw rubber equipped with radial feeding device was improved by 30% comparied with original machine.
