Countinuous Mixers

DATA SHEET

Along with the flexible screw conveyors these units make up an autonomous system for batching, continuous mixing and completely automatic powder conveying system managing flow rates of up to 10,000 kg/h. Solutions with higher flow rates can be studied and supplied.

They can be supplied to satisfy dosing, mixing and conveying requisites as follows: Powder Storage: for two or three materials, whether they are powders, granules or ground materials, and storage volumes according to each individual need. It is possible to start with storage, even directly from the bulk bag.

Individual storage units, bulk bag emptier stations included, can be positioned on loading cells for immediate content control.

Continuous volumetric or gravimetric feed: the feed spirals or screws – one for every produced dosed – are driven by gearmotors with servo-ventilated motors controlled by inverter, or by brushless motors with dedicated drivers.

Powder Mixing and Powder Conveying: with flexible screw conveyors or Shaftless Screw Conveyors that pick up the already batched products and mix them during conveyance from pick up to unloading In cases where it is necessary to have a particularly accurate mix between the multi-ingredient Batching Units and the conveying system, a Continuous Mixer unit is placed in the middle; this unit is commonly called “paddle mixer”.

The unit is made up of a series of adjustable rotating paddles and appropriately configured to enable it to mix the products, previously dosed at the loading mouth, during horizontal conveying towards the flexible spiral conveyor which serves as an elevator.

The pre-mixed product in the paddle mixer will be further homogenized during conveying to its destination inside the spiral conveyor, thereby avoiding the demixing process typical of pneumatic conveying systems; moreover this system improves the quality of the mixture compared to the configuration having only one mixing unit with rotating paddles Special versions and versions compliant with directive ATEX 2014/34/EU for Zone 2 – 22 and Zone 1 – 21 are available on request.
