我厂在技术革命运劝中,车间领导、技术人员和工人共同研究,将干碾机料粉篩网改成4～5层,使料按粒度区分开来,不仅保证了料粉颗粒符合要求,而且也提高了产量。在此基础上又改装了用干碾机生产熟料细粉(<0.088毫米)及一定颗粒组成的料粒,使产量提高一倍,充分发挥了设备的潜力;同时也解决了没有球磨机的困难。由于颗粒组成达到规程要求,产品的理化指标都有提高。现将9号及3号碾机改装情况简述于下。(1)9号碾机:9号碾机砣重7吨(两个砣),砣宽500毫米,砣直径为1200毫米,盘直径2600毫米,转速为28.5转/分,原来用来粉碎山东洪山灼山细粉生产能力为2吨/班。改进后(图1)篩(?)安装角度为45度左右,篩网共有5层,第4层上装有木挡板(300毫米长),第一层篩网为4目,保护篩使大块料不落在第2层篩网上,而使他重新返回碾内粉碎,第2层为60目篩 I plant in the technical revolution advised, the workshop leaders, technicians and workers to study together, the dry milling machine sieve into 4 to 5 layers, so that the material by particle size to distinguish, not only to ensure that the powder particles meet the requirements , But also increased production. On the basis of this, the company rebuilt the pellet made of dry powder mill (<0.088 mm) and a certain amount of pellets, doubling the output and giving full play to the potential of the equipment. At the same time, it also solved the difficulty of not having a ball mill . As the particle composition to meet the regulatory requirements, product physical and chemical indicators have increased. Now No. 9 and No. 3 mill modification is described below. (1) No. 9 mill: No. 9 mill weighs 7 tons (two 砣), 砣 width 500 mm, 砣 diameter 1200 mm, plate diameter 2600 mm, speed of 28.5 rev / min, originally used to crush Shandong Hongshanzhan powder production capacity of 2 tons / class. After the improvement (Figure 1) sieve (?) Installation angle of about 45 degrees, a total of five layers of screen, the fourth layer is equipped with wooden baffle (300 mm long), the first layer of mesh is 4 mesh, Block does not fall on the second layer of screen, leaving him to return to the mill crushed, the second layer of 60 mesh sieve
