EQUIPMENT | DOSING AND FEEDING
Right: Motan- Colortronic has introduced a gravimetric option for its Spectroflex V flexible wall feeding platform
for maintenance. Storage bins also feature generously sized cleaning openings and are easy to remove, even when full. With a network-compatible PLC controller,
Batchmix batch dosing units can be networked with processing machinery and other peripherals from the SOMOS range. Optional packages mean the units can also be adapted for use in an Industry 4.0 setting. Schenck Process has introduced its ProFlex C loss-in-weight feeder family for the compounding and masterbatch industries. The company says that the optimised design, flexible hopper walls and support for a variety of installation options make the new unit well suited for continuous feeding of bulk materials such as powder, granulates, pellets or fibres. The ProFlex is available in three feeder sizes – C 500, 3000 and 6000 – supporting up to five
extension hoppers. The units are easy to clean and feature an easily adaptable and space-saving design that makes it possible to install them in existing and new production plants. For example, the off-centre feeder arrangement allows up to eight feeders with close-fitting discharge helixes and nozzles to be used, while drive and feeder set-up can be customised during assembly. The company says that the direc-
tion of the discharge side can be easily changed at any time, providing even greater versatility, and Schenck Process is
Above: The T35 volumetric feeder from Coperion is designed for handling poor flowing materials
now offering different discharge lengths as standard options. The company says that only two accessible sides are needed for service work. The company says various feed hoppers, gear
reducers, helixes and nozzles are available for adaptation of the ProFlex C to the specific proper- ties of different bulk materials and all models are available in volumetric and loss-in-weight feeder versions.

At the NPE show earlier this year, Coperion showed a twin screw T35 volumetric feeder configured for masterbatch production. The T35 can handle almost any type of material but is said to be particularly effective for materials that tend to clump or bridge, such as poor flowing powders (as well as flakes and fibres). The twin screw feeder features interchangeable feeding tools and all parts in contact with the material being fed are manufactured in stainless steel. A horizontal agitator gently moves material to the throat and into the screws. Feed rate ranges from 1.25 to 2,500 dm3 material.

The company also showed its Smart Flow Meter (SFM), which is designed for reliable metering in high rate applica- tions. The SFM provides high accuracy feeding at feed rates of up to 200,000 dm³/h. According to Coperion, it is less costly to buy and maintain than typical large loss-in-weight feeders and it requires less head room in the plant. The SFM can handle a wide range of free-flowing materials, including granules, powders and fibres, with typical particle size in the range from 0.02 mm to 10 mm. Movacolor has introduced the MCHybrid 30R
gravimetric blender – a new variant of its current MCHybrid 30 the company says is specifically upgraded for the use of lower density regrind materials. The MCHybrid 30R can be customised with a wide choice of hopper models and support systems for loaders. Key features of the MCHybrid 30R include larger volume hoppers for lower density materials and steeper hopper angles to accommo- date poorer flowing materials. Due to their increased weight, the new hoppers are non-removable but draining through the machine is possible. Piovan Group supplies compounding line solutions through its Penta and FDM divisions for storage, feeding and dosing of granules or powder. The company identifies a number of trends in feeding and dosing technology. “Firstly, the management of production facilities is becom- ing more complex with a high number of materials
