Flexible Screw Conveyors Provide Continuous Mixing and Blending
Spiroflow, a leading name among conveyor systems manufacturers, introduces its innovative inline twin screw (ITS) continuous proportional blender. This cutting-edge blender excels in achieving comprehensive mixing within a short material flow distance. It boasts a unique stepless adjustability feature that enables precise blend ratios.
Engineered to handle a wide range of materials, including free-flowing, granular, flake, and pellet substances, the Spiroflow ITS stands out with an outstanding accuracy rate. This blender is tailor-made for various applications in industries such as food, chemical, construction, and more, accommodating a diverse range of specifications.
Innovative Operation of ITS
Within the realm of industrial conveyor systems, Spiroflow ITS presents an inventive solution. This innovative system takes a unique approach by introducing the secondary ingredient directly into the core of the primary ingredient’s flow. It incorporates two rotating spiral-type conveyors with differing diameters. Notably, the steel tube of the smaller conveyor is carefully positioned within the spiral of the larger conveyor, extending beyond the inlet hopper.
This meticulous design ensures that the minor ingredient is introduced precisely at the optimal point for thorough mixing within the primary ingredient. As a result of the Spiroflow ITS’s exceptional mechanical action, it effectively addresses and eliminates ingredient stratification, a persistent challenge encountered in various other mixer types.

Let's See How It Works and What Benefits You Will Enjoy
Spiroflow’s leadership in flexible screw conveyor technology is underpinned by its ability to handle a diverse range of bulk densities, material particle sizes, and flow properties. These attributes establish flexible screw conveyors as a cost-effective and versatile solution for transferring dry bulk solids from one point to another.
Gentle Product Handling
The centerless auger within the conveying tube ensures a gentle material movement that preserves material’s integrity. The constant rotation of the spiral maintains material mixture with constant mixing while conveying.
Design Simplicity
The Spiroflow flexible spiral conveying system prioritizes operational simplicity. With an electric motor-driven spiral as the sole moving component, it operates within a sealed tube, propelling materials forward through Archimedean screw action. This uncomplicated design removes the necessity for supplementary operating equipment like filters or bearings.
Dust-free Operation
Easy to Clean
Cleaning the Spiroflow flexible screw conveyor system is a straightforward task. Reversing the electric motor facilitates the removal of residual materials from the conveyor, followed by a rinse with water or a cleaning solution. If required, the spiral can be swiftly detached from the tube, and the optional quick-release connectors enable rapid toolless disassembly and reassembly, minimizing downtime.
Low Maintenance
Spiroflow’s flexible screw conveyors are designed with a single moving part, the spiral within the tube, spun with an electric motor at the outlet of the conveyor. Minimal moving parts allows for a low maintenance requirement.
Heavy-duty
We provide screw conveyors featuring ultra-high-molecular-weight polyethylene (UHMWPE) tubes designed for abrasive or high-density materials and heavy-duty work
Spiroflow also offers mild and stainless steel tubing for highly abrasive materials. The steel tubing better resists abrasion wear, increasing the life of the conveyor’s tube.
Constant Remixing
These conveyance systems constantly remix materials. A valuable feature when feeding pre-mixed products into packaging and tablet machinery, maintaining mix consistency and product quality.

Spiral Profiles & Tube Selection
For most applications, the standard round spiral is suitable, combining strength and flexibility. Flat section spirals are recommended for certain light or aerated products.The Proscrew beveled profile is used for conveying difficult materials such as iron oxide. The semi-rigid construction enables steep conveying angles to be achieved without bends.
The Centre Core is used for very light materials that fluidize readily and for conveyors inclined more than 60°. They are also used to prevent flooding/overfeeding of certain solids in short or horizontal conveyors.All spirals are heat treated to provide strength and long life. Heavy duty spirals are also available for certain high density or aggressive materials.
Flexible screw conveyor tubes are available in UHMWPE, carbon steel (mild steel), 304 stainless steel.
What Spiral Profiles and Tube Options You Have to Choose From?
The standard round spiral is suitable for most applications, offering a balance of strength and flexibility. Flat-section spirals work well for lightweight or aerated products. Proscrew beveled profiles are effective for challenging materials like iron oxide due to their semi-rigid construction, enabling steep conveying angles without bends.
Center cores are ideal for very lightweight, easily fluidized materials and for conveyors inclined over 60°. They also prevent flooding or overfeeding in short or horizontal conveyors. All spirals undergo heat treatment for durability. Heavy-duty spirals are available for high-density or aggressive materials.
Flexible screw conveyor tubes come in UHMWPE, carbon steel (mild steel), or 304 stainless steel.
