Mouth connects current stabilization storehouse import, and coarse powder exports connection mill entrance in powder concentrator, and the outlet of powder concentrator fine powder connects warehouse for finished product, powder concentrator
Air outlet connects whirlwind recovery cylinder, whirlwind recovery cylinder outlet connection warehouse for finished product, the connection air draft of whirlwind recovery cylinder by circulating fan
Machine, grinding machine export elevator after connection mill, and grinding machine air outlet connects whirlwind recovery cylinder after mill, and whirlwind recovery cylinder exports connection after mill
Elevator after mill, whirlwind recovery cylinder is connected with exhaust blower after mill after mill, and lift outlet connection two cover board of powder concentrator enters after mill
Material mouth；
Advantageous effect：The present invention shares twin shaft birotor multichannel charging grinding system technique before and after providing one kind, utilizes twin shaft
Birotor multichannel powder concentrator substitutes the V-type powder concentrator and dynamic powder concentrator in classical joint grinding system, and the twin shaft is double to be turned
Sub- multichannel powder concentrator drives two rotors respectively by two motors, is classified to material, can allow material by two standards
It is classified, the material coarse powder being classified out sends roll-in system back to and carries out back roller, and middle coarse powder is sent into grinding machine and is ground, and fine powder carries out
Warehouse for finished product is sent into recycling, and the twin shaft birotor multichannel powder concentrator classification efficiency is high, enable back roller material tail over 90% with
On, greatly reduce the acting of roll squeezer；It is used in the front and rear shared twin shaft birotor multichannel charging grinding system technique
Whirlwind recovery cylinder carries out finished product recycling, greatly reduces windage in system, reduces wind turbine energy consumption, while whirlwind recovery cylinder is tieed up
Cost is protected well below bagroom；The twin shaft birotor multichannel powder concentrator at top in addition to entrance is equipped with, two
Two cover board feeding mouths are provided with above road cover board, material can enter in powder concentrator simultaneously from entrance and two cover board feeding mouths
Portion in the grinding system technique, says that the material after grinding machine grinding is directly sent powder concentrator back to by two cover board feeding mouths and carried out
Classification reduces powder concentrator number of devices, substantially reduces equipment cost, and technological process is compact, and system resistance is small, in energy consumption
While greatly reducing, yield greatly improves；Simultaneously, rationally selected in the grinding system using twin shaft birotor multichannel
Powder machine, it is high to the screening precision of powder, finished product grain size degree of unification is greatly improved, final product quality greatly improves；
