We designed our Hapman Helix Flexible Screw Conveyors to provide customers with an economical conveying method that can be used for most types of dry material handling applications. Best of all, Hapman Helix Flexible Screw Conveyors can be selected, ordered, and shipped in 48 hours or less with our Quick Ship program (applies to standard Helix Flexible Screw Conveyors only).
Flexible screw conveyor operation begins when product enters the sealed tube as the auger rotates (the shape, design style, size, and length of the auger are factors selected for each specific bulk material handling application). Flexible screw conveyors are typically mounted to a hopper for easy loading of material. A single motor drives the auger rotation, which pulls the material through the enclosed tube. The helicoid design of the auger effectively conveys a wide range of materials from powder, to granular, to larger particles. The Hapman Helix a good conveying option when your application requires:
Quick Release Inlet Clamp
Quick Release Discharge T Handle and Drive Box
Quick Release Agitator Design with Air Purge Seal
Fits Under Low Ceilings
Hapman offers a wide range of auger styles and sizes to fit in flexible screw conveyor casings 2-8” in diameter (5.08-20.32 cm). Each auger is specifically engineered to effectively move product depending on material type and operating conditions. Our application and engineering team will work with you to determine the best auger for your application.

Sanitize all conveying components to your stringent regulations.
Your best choice for controlled flow of bulk material.
When your bulk material handling needs require a controlled flow without measured output, Horizontal Push Helix Flexible Screw Conveyors are well suited for your needs. Our engineers developed this economical bulk material handling equipment in response to a growing industry demand for simple, easy-to-use conveying systems that reliably transfer product from one location to another.
Horizontal Push Helix Flexible Screw Conveyors reduce instantaneous material load, thus avoiding potential material clogging or back-up. These conveyors also allow for gradually introduced product into a feed line or other production equipment.
Helix 600 Series Flexible Screw Conveyors are suited for quickly and effectively emptying storage totes or intermediate bulk containers (IBCs). The Tri-clover inlet connection is housed under a protective cover that slides to the side when the conveyor is in use. The inlet is designed to mate with the discharge valve of the tote or IBC, signaling the valve actuator to open the valve. As the valve opens, bulk material is automatically discharged into the conveyor, which delivers the product or ingredients to another conveyor, a mixing station, extruder, packaging line, or other process-related area.
Helix Flexible Screw Conveyors can be used in many applications. Here are just a few examples of how the Helix keeps material moving effectively and maintains a safe, clean, and dust-free plant.
Popcorn Packaging Line – A Hapman P300 Helix conveyor is used to refill a Hapman supplied holding hopper above our customer’s popcorn packaging line. This conveyor is serving as an intermittent refill device, sized to stay ahead of the packaging line and refilling to a high-level sensor in the holding hopper as needed. This is a 3” conveyor and the refill rate is about 600 lbs/hour. Material conveyed is salt and popcorn, individually, not as a mix.
Industrial Material Conveying – A tire manufacturer needed a way to convey bulk material from their in-house silos to a common batch hopper. We provided our series 600 (6” diameter) Helix flexible screw conveyors with stainless steel components, complete with butterfly valves located at the conveyor discharge. Each of the conveyors would batch a set amount of ingredients required for making the tires into a common hopper. The average bulk material handling rate for these conveyors was about 6-8 cubic ft per minute. The materials conveyed included Tio2, Zinc Oxide, Carbon black, and Calcium Carbonate.
Salt Pellet Conveying – A food manufacturing company wanted to provide a way for their employees to feed their water softener tanks with salt pellets. The bags weigh about 80 lbs and the tank height is over 5 feet. Our portable 4” Helix flexible screw conveyor dumps the salt pellets into the conveyor hopper at floor level and can be rolled around for use at different tanks.
Building Material Conveying – A roofing manufacturer in Georgia needed a way to convey different color roofing granules weighing about 120 lbs/cubic ft into their mixer. We provided a flexible screw conveyor to feed the mixer, unload the mixer, and send reclaimed product back into the mixer to help minimize product loss. These are 3” conveyors with stainless steel tubes and a heavy-duty square bar auger. The roof granules weighed about 120 lbs/cubic ft.
