Additive dosers

suitable for the dosage of oxides in granules, fibers, polymers, non-dusty resins, settable from the control system. They are made of:

• inverted truncated pyramidal hopper, made of sheet metal and a strong steel frame.
• pneumatic opening
• dosing by means of a fluidizing valve for batch dosing according to material.

The hopper is mounted on load cells, in order to have both weight and volumetric weighing at request and compulsory volumetric during topping up the dosers so as to never have to suspend production. The doser weighs the material for weight loss. Dosing control via PLC and operator panel, where weights and delay times can be set, statuses, alarms, consumptions and cycles can be displayed. The transport of the material to the mixer takes place with a pneumatic method, modulated in pressure and controlled by an inverter.
