Exhausting system is by from air inlet 1 air intake of ball mill front end, by ball grinding cylinder, go out chamber grating,Collecting bin, airduct air draft form the single direction air current flow mode that runs through whole ball mill in ball mill.Air-flow, when the water vapour in ball mill is taken out of, has also reduced the temperature in ball mill. Suitably improveAir flow rate, flow velocity are by the cooling of drying being conducive in ball mill. But because the movement velocity of material is also subject toThe impact of air flow rate, flow velocity, air flow rate, flow rate are higher, and Flow of Goods and Materials speed is faster. Air-flowFlow, flow velocity are excessive, will cause the polished deficiency of time of material just to enter material storehouse, cannot obtain and closeThe material of lattice granularity. Therefore the function of drying and lowering the temperature of existing exhausting system is limited. The use of prior artBetween control end product quality and output, the two cannot take into account wind mode, has the drawback of attending to one thing and lose sight of another. A lotEnterprise all important affair is front by drying materials, reaches the comprehensive moisture content < 1% of mill feed material and is advisable. But the extra baking increasingDry operation, has increased energy consumption and artificial, has affected production efficiency.
Summary of the invention
The object of the invention is: for the problem of above-mentioned existence, provide a kind of ball mill, adopt this ball millNovel structure, can be according to need of production, strengthen flow, the flow velocity of air-flow in grinder, and guaranteeMaterial in grinder, there is sufficient milling time, thereby take into account end product quality and output.
The improved technical scheme that the present invention adopts is as follows: it comprises ball grinding cylinder, collecting bin; Collecting bin one endCommunicate with ball grinding cylinder by going out chamber grating; Collecting bin other end top is connected with blower fan by airduct, and bottom is logicalCharge tube communicates with material storehouse; In described collecting bin, be also provided with induced duct, induced duct one end is stretched in ball grinding cylinder,The other end stretches in airduct, between induced duct and airduct or collecting bin, is provided with deep bead; On collecting bin housingBe provided with air-vent.
