The mixer can be used in a modular fashion by grouping several mixers essentially in side-by-side relationship in a common housing to increase the volume of the mixer.

[ I claim:] [1.] A single shaft mixer for mixing particulates, the mixer having:a housing including parallel side walls and end walls arranged orthogonally with respect to the side walls, and a cylindrical curved bottom wall meeting the side walls tangentially and extending between the end walls, the bottom wall being curved about a longitudinal axis passing through the end walls;a mixing element including a shaft mounted for rotation about said axis and extending between the end walls, and a plurality of inner and outer paddles coupled to the shaft for rotation with the shaft one of the outer paddles nearest the end wall towards which the outer paddles drive the particulates and the one of the inner paddles nearest the other end wall being angled relative to said axis at an angle of about 30 degrees, and the majority of outer paddles and inner paddles being angled relative to said axis at an angle of about 45 degrees; andthe mixer defining a series of mixing zones spaced axially along said shaft, each of the mixing zones including at least one of said outer paddles angled relative to said axis to drive particulates in a first axial direction, and at least one of said inner paddles angled relative to said axis to drive particulates in the opposite axial direction, whereby at least some of the particulates in a said zone move in said axial direction under the influence of said outer paddle and in the opposite axial direction under the influence of said inner paddle, and the zones combine to effect mixing of the particulates.
