摘要: A method and apparatus is provided for the two stage grinding of paper material with controlled addition dry wet fire retardant chemicals to produce a desirable cellulose insulation material. The first ground into coarse granules which are placed in storage hopper systematically fed by an auger fine grinder. At same time that introduced grinder, flow continuously added resultant granular then transported air upward direction where solution liquid sprayed concurrent so as saturate producing product. wetted material, because its adhering qualities, directed through corrugated flexible pipe section storage. An arrangement extending contracting portions prevent from collecting blocking novel bagging allows be directly horizontal bag automatically shutting off when filled. lowered vertical position removal. electrical alarm system conjunction rotary "water wheel" type chemical meter optical meter, controlling operation maintain proper ratio quality
