重庆市华光铸造机械厂生产的S114D型辗轮式混砂机是在S114型辗轮式混砂机的基础上进行改进设计的。适用于铸造车间混制粘土型砂、芯砂、面砂和呋喃树脂砂等,是砂处理工部不可缺少的主要设备。同时也可用于化工、煤炭、轻纺工业混制粉状物料等。该机的主要结构和特点: 由电机带动闭式减速箱,经过主轴、十字头带动辗轮进行混辗,底板围圈采用页岩铸石,刮板采用铬钼铸铁堆焊条、经特殊工艺制成、辗轮设置了弹簧加压机构,出砂门使用气动开门机构等。由于采用了页岩铸石底板、刮板用铬钼铸铁焊条堆制而成,提 S114D roller wheel sand mixer produced by Chongqing Huaguang Foundry Machinery Factory is designed on the basis of S114 roller wheel sand mixer. For casting workshop mixed clay sand, sand core, surface sand and furan resin sand, sand processing department is indispensable main equipment. At the same time can also be used for chemical industry, coal, textile industry mixed powder materials. The main structure and characteristics of the machine: driven by the motor closed gear box, after the spindle, cross head driven by the wheel rolling, floor circle with shale cast stone scraper with chromium molybdenum cast iron welding rod, by a special process Into, the roller set spring pressure mechanism, sand door using pneumatic door opening mechanism. Due to the use of shale stone floor, scraper made of chromium molybdenum cast iron heap, mention
