宇龙第七代不锈钢壳体的木屑颗粒机是在六代碳钢基础上改进的，不锈钢壳体一次冲压成型，不怕腐蚀，使用时间更长久。
模具：超耐磨不锈钢，真空淬火，硬度均匀，强度高，寿命长。
ring die：ultra-wear stainless steel,vacuum quenching,uniform hardness,high strength,long lifetime.
压轮：机器人焊接，表面堆敷超耐磨合金工艺，使用寿命与模具寿命持平。
roller：surface stacking super wear resistant alloy process,lifetime equal to ring die.
压轮轴承：耐高温材质的轴承，增强型密排布滚子，滚道优化结构，承载能力大，寿命长。
roller bearings：high-temperature resistant bearings,enhanced compact arrangement roller raceway optimization structure,high loading capacity,long lifetime.
稳定的传动系统
主轴：一体式贯穿到减速箱内，多段重复定位结构，刚度高，运行平稳。
main shaft：integrated throughout the reducer,multi-section repeated positioning structure,high stiffness,smooth operation.
减速机：自带润滑冷却系统，油压实时监测，无忧全天候长期运行；超工况5倍设计的多级硬齿面斜齿轮，运行稳定、平静；轴承间隙可免拆机调整，节省维护时间。
reducer：with lubrication cooling systm,oil pressure real-time monitoring,worry-free all day long time operation;5 times overworking conditions design of multi-stage hard helical gear,stable opera tion;bearing clearance can be adjusted with no remove machine,save maintenance time.
节省 便利
拨料系统：创新的轨轮式拨料系统，维护方便，使用寿命长；无需持续的干油润滑，定期维护便可，节省润滑成本。
kick-out system：the innovative rail wheel type kick-out system,easy to maintain,long service lifetine;no need for continuous grease lubrication,regular maintenance can save lubrication costs.
便利结构：出料口可多角度旋转，且整机高度明显降低，设备排布更加方便 ，减少挖坑和开顶。
convenient structure：the outlet can rotate at different angles,and the height of the machine is obviously reduced,the equipment arrangement is more convenient,reducing the digging and top opening.
