Mixer-dispenser for granulates (gravimetric dispenser)
50 - 800 kg/h | WBL series DS & M S.r.l., Dosing Systems & Machineries

WEIGHBLEND is an ideal system to feed in continuous extrusion lines (blown film , cast, pipes and profiles ). This system is capable of dosing in continuous up to 5 polymers having a regular particle -size and checking in automatic mode the feed rate.
The use of this system is suggested starting from very low productions of 50 Kg/h and up to productions of 800 Kg/h and more. WEIGHBLEND can be equipped with an automatic weight/meter control. This has the purpose to keep constant in the time the weight of every meter of product which comes out from the line. WEIGHBLEND is constituted by a central gravimetric hopper for the principal ingredient and maximum 4 gravimetric dosing zones for the other ones. The machine has a self supporting structure which allows to fix it directly on the feeding well of the extrusion line.
Each dosing zone has its pre-storage hopper with interception slide gates electro-pneumatically controlled by the gravimetric logic.
The principal ingredient feeds directly for gravity the extrusion line, while the other ones are fed through screw feeders directly in to the feeding flow of the principal ingredient.
