5.磨料辊体重新进行优化设计，设备使用终身不需要换磨机辊体，而旧型对辊机使用一年就需拆开大修，更换辊体。6.本机磨辊上装有可更换耐磨衬板，耐磨衬板采用国内***耐磨材料，具有使用寿命长，不易损坏，方便维修等优点。连续使用寿命可达一年以上，磨损严重时，移开机盖即可更换。维修量小，成本低，这是任何国内其他型式的破碎机都无法比拟的。R900057641PGH5-2X/250RE07VU2-A388R900086557PGH5-2X/200RE07VE4R900086556PGH5-2X/160RE07VE4R900086518PGH5-2X/125RR11VU2R900086321PGH4-2X/040RE11VU2PGH4-2X/032RE11VU2力士乐REXROTH齿轮泵力士乐液压元件分类动力元件：齿轮泵,叶片泵,柱塞泵,螺杆泵；执行元件：液压缸,活塞液压缸,柱塞液压缸,摆动液压缸,组合液压缸；液压马达：齿轮式液压马达,叶片液压马达,柱塞液压马达；控制元件：方向控制阀,单向阀,换向阀；压力控制阀：溢流阀,减压阀,顺序阀,压力继电器等；流量控制阀：节流阀,调速阀,分流阀；R901137885PGF1-2X/2,8RE01VP1R901125550PGF2-2X/011RN20VM-A457R901125549PGF2-2X/006RN20VM-A457R901103807PGF3-3X/022RJ20VU2R901067539PGF2-2X/006RA01VP2-A381R901067272ABUKG-07-12/00K008/PGF2-19/90/S0160SO24R901055744ABHAG-0120SSO/PGF3-025+GF1/132M/014B975AR901054759ABPBG-PGF3-025E4/BG160/LR901050288PGF3-3X/032RN07VM-A447R901036894ABSKG-20AL9/PGF1-2,2/90L/L/1/S02J011AR901029605PGF2-2X/013LN01VM-A279R901021469PGF1-2X/1,7LA01VP1-A340BR901018829PGF2-2X/016RJ01VU2R900HA5596ABHAG-0100RS/PGF2-006/112M/002F433AR900984300PGF2-2X/019LJ20VU2R900984277PGF2-2X/013LL20VMK-A385R900984264PGF3-3X/025LN20VM-A262R900984249PGF3-3X/032RS07VM)
