Abstract
677,634. Preparation of paper pulp. WATFORD ENGINEERING WORKS, Ltd., PARAMOR, J., PLUTHERO, C. P., and RITCHIE, G. Feb. 9, 1950 [Feb. 7, 1949], No. 3358/49. Class 96. Wood pulp, or paper scrap &c. is pulped by feeding it at 11 into a casing 10 supplied with e.g. water from a header 15 and agitating &c. by an impeller 18 rotated at e.g. 350 revs. per minute so that the fibrous material impacts the rough walls of the casing and is directed against perforated walls 21, a suspension of broken-up material &c., entering a compartment 19 whence it enters a tower with a sandtrap at the base, part of the suspension being recirculated by a pump &c. to clean the inside of the walls 21. Trash passes through an outlet and is removed by a conveyer.
