RBC single-shaft batch ribbon blenders
The RBC single-shaft horizontal batch ribbon blenders range represents the ideal solution to delicately and thoroughly mix fragile and delicate materials.
Thanks to the four counter-rotating ribbon flights that move the materials across the length of the mixing trough, from the middle to the sides and vice versa, these horizontal batch blenders hare particularly suitable to handle dry powders and granules, whose intrinsic characteristics must not be modified and that must not be broken or squashed in any way.
RBC single-shaft horizontal batch ribbon blenders are made up of mixing trough, with one or more inlets, one vent port, one or more outlets, one main rotor shaft that rotates inside the trough, to which four concentric counter-rotating ribbon flights are fixed that mix the ingredients fed through the inlets. The flights delicately move the materials backwards and forwards across the trough, simultaneously pushing them from the centre to the ends, and vice versa. Two end plates close the trough at both ends: the shaft supports, complete with bearings and seals, are bolted to the end plates. An electric drive unit is coupled to the main shaft and guarantees the correct rotation speed of the shaft inside the mixing trough.
RBC single-shaft horizontal batch ribbon blenders are made of mild steel or stainless steel (AISI 304 or AISI 316).
The shaft is made from a high thickness pipe, the ends are welded and lathed to a high degree of precision to guarantee a perfect fit and coupling within the end supports.
The end supports are fitted with the main shaft bearings, together with the main seals to prevent any leakages from the mixing trough. According to the application for which the blender is designed, the main shaft seals can be of different types (simple stuffing, air/nitrogen purged).
The four, concentric, counter-rotating flights delicately push the materials back and forth inside the trough simultaneously from the centre to the ends and vice versa, guaranteeing a thorough particle distribution.
Inlets are made according to application and installation requirements (various shapes and sizes possible).
The central outlet, ensures that all materials are discharged once mixing operations have been completed, with a very low residue left inside the trough.
All RBC single-shaft horizontal batch ribbon blenders come equipped with lids, bolted or hinged, enabling the operator/service technician to perform cleaning or maintenance operations. Upon request, additional side inspection doors can be fitted. Both lids and inspection doors are fitted with safety mechanical or electro-mechanical locking devices, that prevent them from opening while the blender is in operation. Bolted or hinged grids can be fitted beneath the lids, upon request.
Every RBC single-shaft horizontal batch ribbon blender is supplied with a specifically sized and configured drive unit, according to customer and application needs. Simple, compact drives are preferred for low power, simple configurations, while larger units with higher installed power will be supplied with independent, self-supporting, drive units with flexible pin coupling.
- Delicate mixing: RBC single-shaft horizontal batch ribbon blenders require a medium-long mixing time. Ideal when handling delicate, thermo-sensitive and fragile materials, that cannot be broken or vigorously tumbled, these blenders are the perfect solution when handling fragile ingredients such as flakes.
- Low power consumption: with their low speed RBC ribbon blenders do not require high installed power and consequently benefit from low energy consumption.
- Batch repeatability: although slower when compared to other more vigorous mixing technologies, RBC ribbon blenders maintain an excellent batch repeatability in time
- Know-how and experience: thanks to its extensive experience, MC2 guarantees its customers full support at all times
