我厂砂处理工部,原来采用人工开箱、落砂,用小车把旧砂运到混砂房,人工打碎砂块和过筛,由斗式提升机将旧砂加入六角筛过筛,再由爬斗把旧砂加入两台S116型混砂机内。新砂、粘土等也用人工加入爬斗。每天混砂量30～60吨,共需工人30余人。工部内粉尘浓度较高,劳动条件差。这种状况不能满足生产发展的需要,必须迅速改变。 I sand factory processing department, the original artificial out of the box, off the sand, with the car to the old sand sand mixed room, artificial broken sand and sieved by the bucket elevator will join the old sand sieve hexagonal, Then by the bucket to join the old sand two S116 mixer. New sand, clay, etc. are also manually added to climb bucket. Amount of sand mixed 30 to 60 tons a day, a total of more than 30 workers. Ministry of dust concentration higher, poor working conditions. This situation can not meet the needs of the development of production and must change rapidly.
