TURBODISPERSER/MIXER, MERCURY LINE, MODEL BI

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 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 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.

PLANETARY MIXER/DISPERSER UNDER VACUUM, STEEL LINE, MODEL BI

Main transmission mixing shaft

Main electric motor with frequency converter (inverter). The power transmission between the electric motor and mixing shaft occurs by means of gear box coupled to pulleys and belts with profiles and suitable dimensions.

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.

Planetary Box
The planetary box is composed of shafts and gears that allow the rotation of more shafts simultaneously, beyond its own rotation. The high ration power-weight and the compact dimensions, ensure the application of high powers on tools, in relatively small spaces. New criteria have been used to substantially improve noise level. The spur gears are with rectified helicoidal profile, after heat treatment on the external part, meanwhile, they are with a spline profile in the internal part of shrinking of the transmission shafts and are made of hardened and tempered steel. All the gears have been designed and tested according to the ISO 6336 and ISO 10330 Standards. The transmission shafts are constructed with external splined profile (coupling with a toothed wheel) and with an internal grooved profile (coupling with tool). The planetary box is driven in an independent way, by means of an electric gearmotor. Planetary box is closed on the bottom part, the one in contact with the product, by means of a removable casing, in AISI 304 stainless steel.

Company details

In 1956 Zanelli Vincenzo undertakes a craft activity in the field of general metalworking construction.
In 1962, with the help of his son Gianfranco and his daughter-in-law Carla, the Company becomes ZANELLI s.r.l., specializing in the design and in the construction of plants for the chemical industry.

Today, ZANELLI s.r.l. celebrates the 50th anniversary of its foundation.

In these first 50 years of activity, ZANELLI s.r.l., questi primi 50 anni di attività la ZANELLI s.r.l., now arrived at the third generation, makes the spirit of cooperation of a family its point of strength, making it the protagonist of an entrepreneurial continuously growing path, directed to meet in the most appropriate way the needs of its Customers.

From its foundation until today, the Company has grown under the sign of technological innovation, with products of the highest quality and reliability, thanks to efficient and skilled collaborators, up to date on innovations, on Standards and paying attention to the needs of an increasingly demanding and evolved market.
