在水电工程的人工砂石料系统中通常采用捧磨机制砂。棒磨机制砂具有以下优点:1.产品粒形良好,产品粒度特性稳定。当细度模数确定后,其粒度级配也就基本确定。2.可以根据需要通过调整给料量、料浆浓度、装棒量等人为地控制产品细度模数。3.棒磨机的结构比较简单,操作方便,生产稳定,工作可靠,可以长期不停机运转。4.适于各种硬度岩石特别是中高硬度岩石的制砂。但是现在生产的棒磨机在生产率、单位能耗、钢耗方面均不理想;进料粒度较小,一般要求小于25mm(当棒磨机直径大于2.4m 时给料粒度可扩大至50mm),增加制
Holder mill sand is commonly used in hydro-gravels for artificial gravel systems. Rod grinding machine sand has the following advantages: 1. The product has good grain shape and stable product particle size characteristics. When the fineness modulus is determined, the granularity gradation is basically determined. 2. It is possible to artificially control the fineness of the product by adjusting the feed amount, slurry concentration, loading rod amount, etc. as required. 3. The structure of the rod mill is relatively simple, easy to operate, stable in production, reliable in operation, and can operate without stopping for a long time. 4. Suitable for sand making of various hardness rocks, especially middle and high hardness rock. However, the rod mills currently produced are not ideal in terms of productivity, unit energy consumption, and steel consumption; the feed particle size is small, and the general requirement is less than 25 mm (when the diameter of the rod mill is more than 2.4 m, the feed particle size can be expanded to 50 mm).
