Main transmission mixing shaft Main electric motor with frequency converter (inverter). Gear box with parallel axes. The power transmission between the electric motor and the gearbox occurs by means of pulleys and belts with profiles and suitable dimensions. Main transmission dispersing shaft Main electric motor with frequency converter (inverter). The power transmission between the electric motor and the mixing shaft occurs by means of pulleys and belts with profiles and suitable dimensions. Auxiliary Hydraulic Power Pack Hydraulic power pack positioned in the machine structure, complete with electric motor, coupling strainer, coupling, pump, solenoid valves, oil level, vent, drain cock and safety devices. The power pack actuates the hydraulic cylinder, complete with safety lock valve. The cylinder is placed in the center of the two fixed columns and is suitable to lift up the entire mixing group. Mixing tools The dispersing shaft, in AISI 304 stainless steel, is balanced with adequate taper on the edge, in order to ensure the elimination of vibrations even in the most critical stages of processing and at high speed rates. The change in speed of the dispersing shaft is obtained by means of an electronic system complete with frequency drive (inverter). The advantage is that the operator has a range of speeds available but especially there is a high torque even at medium/low speeds. Continuously variable speed. The dispersion tool, supplied with the machine, is a toothed impeller with an easy fixing to the shaft, easy to replace.

The dispersion tool, supplied with the machine, is a butterfly impeller with an easy fixing to the shaft, easy to replace. Three supports, fixed at the edges of the butterfly, made of AISI 304 stainless steel, are suitable to support the lateral scraping blades, complete with interchangeable Teflon profile, screwed. Mixing vessel Vessel made of AISI 304 stainless steel. AISI 304 stainless steel reinforcement top ring. Intermediate band, in AISI 304 stainless steel, with fixings to support basement. Vessel with rounded bottom and connected to vertical plating. Discharge in the central part. Mixing shaft and dispersing shaft vertical stroke The vertical movement of the two mixing/dispersing tools, called stroke, is obtained by 2 pneumatic pistons. The possibility to adjust the correct height of the mixing/dispersing tools, in relation to the quantity of product contained in the vessel, ensures a high flexibility to the machine and also allows to optimize the mixing flow, granting a fast incorporation of raw materials and, in case of machine under vacuum, to speed up air extraction from the product. The stroke is achieved by the sliding of two fixed sleeves, complete with bearings and seal rings, fixed to the lid, and by two mobile sleeves, coated with rectified hard-chrome, fixed to the mixing group, which also act as bearings support of the mixing shaft. Frame The structure of the machine, called frame, is composed of sturdy construction in carbon steel, treated with a two-components epoxy paint. It is complete with a base plate with suitable holes for fixing to the floor, by means of chemical anchors brackets. Two columns, complete with sliding bushings, are fixed to the side of the structure and house two mobile columns, coated with rectified hard-chrome, wear-resistant. This technical solution gives a high strength to the machine, even in the most critical phases of the production cycle, minimizing vibrations.
