The development of bucket wheel stacker reclaimers in my country
The development of domestic bucket wheel stacker reclaimers has basically gone through three stages. In the 1960s and 1970s, China began to design small bucket wheel stacker reclaimers, with typical models such as 3025 and 8030, with reclaiming outputs of 300t/h and 800t/h, and turning radius of 25m and 30m, respectively. The 1980s and 1990s were the second stage of the development of bucket wheel stacker reclaimers. Newly built bulk material yards such as steel mills and power plants gradually adopted large bucket wheel stacker reclaimers for bulk material stacking and transportation. For example, in Shanghai Baosteel and Qinhuangdao Wharf material yards, bucket wheel stacker reclaimers have a reclaiming output of 2000t/h and a turning radius of 40m. Limited by the domestic conditions at the time, the construction of these material yard conveying equipment was mostly cooperatively manufactured or imported as a whole machine, and even the entire bulk material conveying system was introduced from abroad. After 2000, the development of domestic bucket wheel stacker reclaimers has reached a new stage. So far, domestic manufacturers have the ability to design and manufacture bucket wheel stacker reclaimers with a production capacity of 300-6000t/h and a slewing radius of 25-60m. During this period, foreign manufacturers still occupy a certain share, but domestic manufacturers have mastered considerable technology and production capacity, and have occupied the mainstream position in the domestic market with their service and price advantages, and are gradually moving towards the international market.
