A vehicle-mounted mixer has a mixing container 2 with an open top and a bottom formed as two arcuate troughs, with intermeshing screw conveyer stirrers 12, 13 of the same kind and pitch less than 45 degrees; to permit counter-rotation during mixing, Fig. 3, they have recesses 16 in their peripheries ; there may be six recesses in each turn of the screw, Fig. 8. Screw sections 21 of pitch greater than 45 degrees, or plates 30, 31, 32 assist lateral transfer of material between screws ; there may be apertures 22 to prevent overload. The peripheries of the screws may have adjustable wear plates 18 ; the screws may be made in replaceable sections, see Fig. 7 (not shown). The portions 17 of the screws between the recesses 16 are additionally twisted towards the screw axis so that the axial projections of their outer edges overlap to prevent unswept strips being left; the additional twisting takes place in the roots of the sections 17, the outer edges being straight so that the wear plates 18 can be adjusted, each section having the pitch of its middle point. The screw thus constitutes two screws, an inner one of lesser pitch and an outer one of greater pitch. To empty the mixer, the direction of rotation of screw 13 is reversed so that both screws deliver into a discharge shoot 14. Locking means may be provided in the gear-box 5 to allow reversal to take place only when the screws have the same rotational position, or means to allow the screws to run on until they are in alignment. The reversible screw may have a portion of smaller pitch at the end nearer the mixer discharge outlet to provide additional discharge pressure.
