Zanelli Lithium Line Single Shaft Production Disperser

The Zanelli Lithium Line is a single shaft production mixer/disperser for mounting through the floor with vertical stroke and a liftable lid.

LITHIUM LINE

The Zanelli Lithium Line is a single shaft production mixer/disperser for mounting through the floor with a vertical stroke and a liftable lid. It has an electrical motor of 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 vessel maximum capacity is up to 10,000 litres. The impeller vertical stroke movement is obtained through two pneumatic pistons.

TURBODISPERSER UNDER VACUUM, LITHIUM 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 shaft vertical stroke The impeller vertical movement, called stroke, is obtained by 2 pneumatic pistons. 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. The stroke is achieved by the sliding of a fixed sleeve, complete with bearings and seal rings, fixed to the lid, and by the mobile sleeve, coated with rectified hard-chrome, fixed to the mixing group, which also acts as bearings support of the mixing shaft.

 

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.

 

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.

 

Frame The structure of the machine, called a frame, is composed of sturdy construction in carbon steel, treated with a two-component 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 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.

Models

Options:

 

Independent Shaft 

Dispersing shaft and revolving scraper

A balanced dispersion shaft with an adequate taper in the final part ensures the elimination of vibrations during the most critical processing phases, even at high speed. The dispersion tool supplied with the machine is a toothed disc type with a quick fixing system to the dispersing shaft with easily replaceable.

Independent lateral revolving scraper with a self-regulating system in order to obtain a perfect cleaning of the internal lateral surface of the tank and at the same time convey the processed product towards the dispersion impeller reducing production times.

Vertical Excursion 

Vertical excursion of the dispersing shaft

The vertical movement of the dispersion impeller, called EXCURSION, happen through the use of pneumatic pistons.

The possibility of adjusting the correct height in relation to the quantity of product contained in the tank might guarantee high flexibility to the machine and also this is allow to optimize the mixing flows, and have fast incorporation of the raw materials. In the case of an under vacuum machine, the vertical movement speeds up the air extraction from the product.

Electrical Motor

Main Transmission

Main electrical motor fixed to the mixer unit complete with pulley-type transmission and belts with profiles and dimensions suitable for the installed power.
