Need to transfer powders, granules, fibers or shredded material?
The TIM TRANSITUBE range of flexible mechanical feeders provides solutions to
over 95% of transfer applications for these different materials.
Transfer operation
The flexible mechanical feeder enables automatic transfer of plastic material from injection molding machines, extrusion and blow molding machines, mixers and any hopper or silo.
All bulk products are transported in sealed circuits, with no dust emissions.
A material intake probe at the start of the feeder is fixed under a hopper, a silo, a big-bag...
The spiral, an essential element of the transfer, is made from a special spring steel that has been specially treated to improve its strength and flexibility. Driven by a motor, it creates a ring of material that moves inside the tube.
Depending on the profile selected, the spiral conveys a wide variety of products, such as plastic granules, regrinds, PVC powder, additives or various mixes.
Plastics with good flow properties, such as Polyproprylene (PP), the Polyethylene high and low density (HDPE and LDPE), the Polyamide (PA or Nylon), the Polystyrene crystal (PS), the Dry Blend (a mixture of PVC, CACO3 and additives), the Polyvinyl chloride PVC... are easily transported by the flexible screw.
These plastics - often in pellet form - are usually conveyed by a flexible feeder without a devourer.
The use of poorly flowing products often leads to problems with silo extraction, dosing accuracy and feeding during material transfer.
The TRANSITUBE ZFP type devourer-extractor is a flat-bottomed hopper equipped with a special devourer with flexible or semi-rigid blades, particularly suitable for difficult-flowing products such as powders like talcthe calcium carbonate (CACO3), the Coumpounds elastomers (SEBS-type TPE), the Plastic-coated PVC, TIO2the crushed film.... This devourer's extractor allows variable flow rate dosing depending on the application required. Connected to a TRANSITUBE PV series flexible mechanical feeder, the product is then conveyed to the point of discharge.
This unit can be grouped with other feeders to create a multi-product process.
- Dosing accuracy: Allows highly precise continuous dosing: 0.5 to 3% depending on the product.
- Ease of transfer: Products with poor flowability in a wide flow range up to 6000 kg/h by coupling with a TRANSITUBE flexible mechanical feeder.
- Modular: It can be incorporated as a dosing unit in a volumetric dosing carousel.
- Flow ranges: from 30 to over 10,000 kg/h
- Unlimited transfer distances: relay connection of feeders.
The flexible screw feeder can be harmoniously combined with other injection molding machine peripherals, such as the grinder, dryer, doser, colorer and pneumatic conveyor.
The virtues of flexible screw transfer
Easy to install
The flexible mechanical feeder bypasses obstacles. No detailed plans are required for installation, as the feeder can be quickly adjusted during assembly.
Blend homogenization
... during transfer!
Even if the density and particle size
of the products are different.
Low operating costs
Economical: a flexible screw consumes just 2.2 kW/h for a flow rate of 5000 kg/h over 6 meters.
Cleanliness
No dust emissions.
Products transported are protected from all environmental pollution.
Moisture protection
Products are protected from the surrounding humidity, which is essential for dehydrated or dried products that cannot be transported by pneumatic conveyors.
Quality of life at work
By transferring plastic materials (powders, granulates, shreds) by pigtail, MSD risks and operator fatigue are reduced.
* Low noise level (<80 db)
