Apparatus For Making Cellulose Insulation

US Patent:
4191224, Mar 4, 1980
Filed:
Aug 5, 1977
Appl. No.:
5/822232
Inventors:
Kenneth L. Bontrager - Jefferson County CO
Marion R. Bontrager - Phoenix AZ
Robert J. Taylor - Denver CO
David C. Card - Denver CO
Assignee:
Diamond Insulation Industries, Inc. - Denver CO
International Classification:
B05C 500, B05C 1110
US Classification:
141100
Abstract:
A method and apparatus is provided for the two stage grinding of paper material with the controlled addition of dry and wet fire retardant chemicals to produce a desirable cellulose insulation material. The paper is first ground into coarse granules which are placed in a storage hopper and systematically fed by an auger into a fine grinder. At the same time that the cellulose material is introduced into the fine grinder, a controlled flow of dry fire retardant chemicals is continuously added and ground with the material. The resultant granular material is then transported by air in an upward direction where a solution of liquid fire retardant chemicals is sprayed in a concurrent direction with the flow so as to wet and saturate the cellulose material producing a fire retardant product. The wetted material, because of its adhering qualities, is directed through a corrugated flexible pipe section to storage. An arrangement is provided for extending and contracting portions of the flexible pipe to prevent the material from collecting and blocking the flow of material.

Cellulose Insulation Storage Bin With Improved Debridger

US Patent:
4171165, Oct 16, 1979
Filed:
Jul 17, 1978
Appl. No.:
5/924950
Inventors:
David C. Card - Denver CO
Assignee:
Diamond Insulation Industries, Inc. - Denver CO
International Classification:
B01F 708, B01F 720, B01F 1502
US Classification:
366186
Abstract:
An improved debridger is provided in one or more storage bins in a cellulose insulation manufacturing plant which minimizes the bridging of the cellulose insulation across the storage bins between an inlet at the top thereof and an auger-fed outlet at the lower end thereof. The debridger comprises a vertical rotatable shaft having a plurality of horizontally extending arms for agitating the insulation and minimizing bridging. The arms or vanes on the auger vary in length and are removable from the vertical shaft for installation of the shaft in the bins. The shaft is rotatably driven by power means located outside of the storage bin.
