Abstract A pin mixer for mixing particulate solids having a rotor with a plurality of radially extending pins removably attached thereto. The pins form a plurality of axially and radially staggered helices along the rotor, and pins adja- cent the inlet of the mixer are interconnected by a solid ribbon. Adjustable fluid nozzles are provided in the inlet for mixing fluids with the solid particulate material. The pin mixer has a pair of bearings, a pair of seals located inwardly from the bearings, and a pair of discs attached to the rotor thereof. A first pressure source may be connected between each bearing and seal to assure that leakage across the seals is away from the bearings, and a second pressure source connected between each seal and respective disc so that leakage between the disc and shell is away from the seals. The rotor has a pair of detachable stub shafts, and a means is provided to quickly change the rotor and shell without disturbing the connection to the power source. baffle adjacent the outlet, and a baffle adjacent a vent opposite an outlet, provide a means for varying the flow rate through the apparatus to vary the amount of mixing therein. The baffles are externally adjustable. -32-
