Zanelli Mercury Line Twin Shaft Production Mixer / Disperser

Zanelli Mercury is Twin shaft production mixer/disperser for ground mounting with change pan.

Zanelli Mercury Line Twin Shaft Production Mixer / Disperser

The Mercury Line is a twin shaft production mixer/disperser for ground mounting with a change pan. It has 2 electrical motors up to 160 kW complete with frequency inverters. This machine is suitable to mix or disperse products having a high viscosity of up to 1,000,000 cP. The movable vessel maximum capacity is up to 1700 litres. The impeller vertical stroke movement is obtained through two pneumatic pistons. 

TURBODISPERSER/MIXER, MERCURY LINE, MODEL BI

Main transmission mixing shaft Main electric motor with frequency converter (inverter). Gearbox 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 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 The dispersing shaft, in AISI 304 stainless steel, is 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 dispersing 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.

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 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, 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 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 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.

Models

BI: Undervacuum version Machine with vertical movement of the mixing and dispersing shafts during the various process phases by means of sleeves and sliding cylinders.

AI: Machine in the standard version with vertical movement of the mixing and dispersing shafts during the various process stages by means of sleeves and sliding cylinders.

CI: Machine in the standard version with vertical movement of the mixing and dispersing shafts during the various process phases by means of protective bellows and sliding guides.

Options:

 

Independent Shafts 

Dispersing and mixing shafts

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.

A balanced mixing shaft ensures the elimination of vibrations during the most critical processing phases, even at high speeds. The mixing tool supplied with the machine is butterfly type with a quick fixing system to the mixing shaft for easy replacement.

Vertical Excursion 

Vertical excursion of the dispersing shaft

The vertical movement of the dispersion impeller and butterfly impeller, called EXCURSION occurs through the use of pneumatic pistons.

The possibility of adjusting the correct height in relation to the quantity of product contained in the tank guarantees the machine high flexibility, also allows to optimize the mixing flows, guarantees the fast incorporation of the raw materials and in the case of vacuum machine speeds up the air extraction from the product.

Electrical Motors 

Main transmission

Main electrical motors and speed reducer fixed to the mixer group complete with pulley-type transmission and belts with profiles and dimensions suitable for the installed power.

Two Columns 

Two columns structure

On the side of the mixer group, there are two mobile columns coated in hard chrome, ground and wear-resistant, with a technical solution that gives the machine a high strength even in the most critical phases of the production cycle, minimizing vibrations and increasing stability.

 

Applications

Inks, Glues, Mastics, Adhesives, Sealants, Plastics, Cosmetic Products, wall fillers, polyester stuccoes, silicones.
