立式环模成形机改进设计

The improved design of ring mold forming machine

分析已有平模、环模成形机的特点，充分考虑两者的优点，改进环模成形机的结构，设计了有较大优越性的立式环模成形机。实际生产表明，优化后设备的生产率提高38％～70％；环模磨损均匀，得到了最大限度的利用，寿命至少提高87％。立式环模成形机很大程度上降低了生物质颗粒的生产成本，提高了实际生产效率。

The characteristics of existed flat and ring mold forming machine have been analyzed. The structure of ring mold forming machine has been improved through considering advantages of the two kinds of machines. The vertical ring mold forming machine has been developed with large advantages. The actual production shows that the productivity has been improved dramatically by 38%-70% and the ring mold has been worn uniformly that could be fully used of which the lifetime can be enhanced at least by 87%. The machine could reduce the cost and promote the practical production.
