Zanelli Vanadium Line Single Shaft Mixer / Disperser

Zanelli Vanadium Line Single Shaft Mixer / Disperser

The Zanelli Vanadium Line is a single shaft mixer/disperser with a fixed lid for mounting through the floor The electrical motor is available is sizes up to 250 kW complete with a frequency inverter and a rotating scraper. This machine is suitable to mix or disperse products having a low or medium viscosity up to about 500.000cP. The movable vessel maximum capacity available is up to 15,000 litres. The impeller vertical stroke movement is obtained through two pneumatic pistons and it also has a rotating scraper.

TURBODISPERSER UNDER VACUUM, VANADIUM LINE, MODEL BIRG WITH ROTATING SCRAPER

Main transmission Electrical motor complete with frequency converter. The power transmission between the electric motor and the mixing shaft takes place through pulleys and belts with profiles and appropriate sizes.

Auxiliary Hydraulic Power Pack Hydraulic power pack positioned in the machine structure, complete with an 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 a safety lock valve. The cylinder is placed in the centre of the two fixed columns and is suitable to lift up the entire mixing group.

Mixing tools Dispersion shaft in AISI 304 stainless steel, balanced with an 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 mixing shaft is obtained by means of an electronic system complete with a 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.

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 group The upper part of the machine, flanged and supported by the mobile column, is complete with an openable cover, composed of a sturdy carbon steel construction, suitable to house the main transmission and to support the dispersion shaft. The system consists of two lateral columns, integral with the lid on the vessel, complete with suitable sliding bearings, which house inside two mobile columns, coated in rectified hard-chromium, wear-resistant. Columns are fixed to the mixing group and grant a high stability even in the most critical working conditions.

Mixing shaft vertical stroke The impeller vertical movement, called stroke, is obtained by the sliding of the fixed sleeve, complete with bushings and seal rings, fixed to the lid, and by a movable sleeve, coated with rectified hard-chrome, fixed to the mixing group, which acts also as bearings support for the mixing shaft. The possibility to adjust the correct height of the mixing/dispersing tool, in relation to the quantity of product contained in the vessel, ensures high flexibility to the machine and also allows to optimize the mixing flow, granting fast incorporation of raw materials, and in case of the machine under vacuum a speedy air extraction from the product.

Rotating scraper group Rotation of the scraper is obtained via an electric geared motor coupled to a pinion and to a fifth wheel, both lodged within a sealed box, fixed to the lid. An AISI 304 stainless steel revolving sleeve is fixed to the rotating fifth wheel and supports scraper arm, tubular-shaped, built in a sturdy sheet of AISI 304 stainless steel, complete with a self-adjusting tang, suitable to support the lateral scraper blade, in AISI 304 stainless steel, complete with interchangeable screwed profile, made in a suitable material.
