Abstract
A continuous feed mixer for cement or other mixtures includes a mixing tube which is inclined downward from a feed end to a mixing end. Cement solids are deposited at the feed end. Water is introduced at various locations along the length of the mixing tube to provide a proper proportion of solids and water. The mixing tube is rotated to provide the desired mixing process. A scraper is positioned within the mixing tube to remove material from an inner wall of the mixing tube during the mixing process.
