Dispersion shaft, made of balanced stainless steel ensures the elimination of vibration during even the most critical stages of processing and at high speed regimes.

Variation of dispersion shaft revolutions is by means of an electronic system with a frequency shifter (inverter) combined with the main electric motor.

The advantage of the electronic system described above is the range of speeds available to the operator but especially the high torque even at medium/low speed ranges.

The dispersing tool supplied with the stainless steel machine is of the notched disk type, with a system of fastening to the dispersing shaft quickly and easily replaceable.

REQUEST INFORMATION

The vertical movement of the impeller, called excursion, takes place through the use of

Two pneumatic pistons.

The ability to adjust the correct height of the dispersion/mixing tool in relation to the amount of product contained in the tank provides the machine with high flexibility, it also allows optimization of mixing flows ensuring fast incorporation of raw materials. The excursion is obtained through the sliding of a fixed tube with sealing rings, fixed to the cover and a mobile tube covered with rectified hard-chrome fixed to the mixing unit which also acts as a bearing support for the mixing shaft.

REQUEST INFORMATION

Tank closure lid constructed of stainless steel complete with some accessories:

– Raw material loading hopper with side dust containment protrusions

– Stainless steel protection net.

– Suitable attachments to the two pneumatic lid handling cylinders

– Coupling flange to fixed sleeve.

– Connection arranged for connection to dust and fume extractor, if any.

Additional options can be considered following specific customer needs.

REQUEST INFORMATION

The main structure of the machine consists of a sturdy painted iron plate construction complete with a base plate with appropriate holes for floor fixing.

In the front of the frame stainless steel cladding that facilitates any cleaning operations.

Two columns complete with sliding bushings are attached to the side of the structure in order to house two wear-resistant hard chrome-coated ground movable columns inside them.

This technical solution gives the machine high robustness even in the most critical stages of the production cycle with optimal absorption of vibrations caused by machining tools.

It houses inside the structure the hydraulic power unit complete with electric drive and safety devices.

The control unit operates the hydraulic cylinder complete with safety lock valve.

The hydraulic cylinder located in the center of the two fixed columns is suitable for lifting the entire mixing unit and enclosed within a protective bellows.

REQUEST INFORMATION

The Machine Control System consists of an Industrial Multi Touch Screen type PC on which a SCADA Supervision System is run.

The machine’s control and safety logic is entrusted to a PLC interconnected to the PC via the ProFinet field bus.

The PC is powerful enough to host a state-of-the-art Relationship Database (Microsoft SQL Express) on which the recording of all machine functional parameters and event history (alarms, values of quantities, etc.) takes place.

Through a user-friendly operator interface, the operator will have complete control of the machine’s various functions in a simple and intuitive way by accessing the various control pages.

The PC is arranged to have a dual network interface (configurable by the customer) so that it can be securely interfaced to the corporate network while facilitating access to the Remote Control system by Zanelli personnel.
