Real water drop figure grinding chamber design, beyond image and full of connotation. Interlocked screen hold-down fixture (patent) helps to change two-step or multi-step screen pressing into one-step processing, which avoids screen pressing unevenness caused by multi-step working, so that the grinding chamber is guaranteed to run in a fully sealed situation. Patent No. ZL98 2 42415.9 Each rotor is tested and checked in high-precision and dynamic balance in a strict way in order to ensure machine stable running and reduce wearing of bearings and hammer holders, so repairment of equipment is minimized,production efficiency is elevated,and service life of equipment is extended.The machine is equipped with humanized designed sliding opening access door, ease of operation and maintenance,and reduction of labor intensity.Patent No. ZL 98 2 42414.0 The high-precise 14px-diameter rotor is tested by dynamic balancing, enhancing grinding efficiency. Real water drop figure grinding chamber design, quick discharging. "W” shaped double grinding structure, output increases by 25%Sliding fully-opening access door,interlocked screen hold-down fixture, more convenient operation and maintenance.
