What’s the Difference Between Helicoid Flighting and Sectional Flights?

Augers provide a critical function for the conveyance of materials. Smooth operation depends upon the precision of the auger fins or blades, commonly referred to as flights. There are two main processes used in the production of auger flights: helicoid and sectional.

Formation of each type involves a different process and produces unique characteristics.

What Are Sectional Flights?
Sectional flights are auger blades individually formed from plate steel into a helix. The process for creating sectional flights goes as follows:

The process begins with a piece of plate steel cut into a donut shape with a specified inside diameter (ID) and outside diameter (OD).

A press shapes them into the form of a helix.

Each of these helixes is an individual component joined to create a series of flights or a continuous helix.

Final formation of the auger includes attaching the finished continuous helix to a shaft.

Sectional flights are of uniform in thickness from their ID edge to their OD edge.

The sectional flight process allows for a greater variation in design, material thickness, and material used, but more handling is required to form sectional flights into a finished auger.

What Is Helicoid Flighting?
Rather than formation in sections, helicoid flighting are created as a continuous helix formed from a single piece of carbon or stainless steel. This process includes:

Rolling machines with cone-shaped dies are set to specific ID and OD dimensions to transform a strip of steel stock by rolling it into a single continuous helix.

This compression process causes the OD edges to become thinner in contrast to the uniformity of sectional flights.

Forming a single helix saves time and money, but there are limitations as to the materials, design, and material thickness using this method.

Benjamin Franklin was an author, inventor, politician and one of the Founding Fathers of the United States. He may also have had the uncanny ability to see into the future of the bulk material handling industry.

One of the most quotable figures in history, Franklin once famously said: “Write injuries in dust, benefits in marble.” That particular comment referred to focusing on the positives in life rather than the negatives. But the words “injuries” and “dust” are applicable to industrial material handling operations, which didn’t exist in Ben’s day.

Dusting is one of the most common challenges for bulk material processors, largely due to the safety risks that stem from ineffective dust collection. Identifying the causes of dusting, implementing fixes and understanding the huge impact dusting can have on safety are critical to addressing the issue before it becomes a major problem. Fortunately, proper dust control for bulk materials is achievable with the right equipment solutions from To.

The Danger of Dusting is Real
Compliance with Government regulations is always advisable for any industrial facility, but one word stands out above all: “combustible.” Airborne dust associated with the movement and handling of materials such as sugar, starch/flour and coal has properties that make it highly flammable, and in many cases, capable of causing an explosion.

Dust explosions caused by airborne dust or excessive dust accumulations, which have been responsible for much of the damage and many of the injuries resulting from major industrial explosions.

Additionally, employees who work in environments impacted by dusting are far more likely to experience safety concerns from coated surfaces. Airborne dust increases the risks to employees for injuries or other ailments caused by slip-and-fall accidents.

Equipped to Address the Industrial Dusting Issue
The threat dusting presents should not be taken lightly. Addressing it may appear to be daunting, but you don’t have to go it alone. Todd Augers offers a variety of dust control equipment that can help mitigate the threat and its impact on an operation. Our recommendations always depend on the specific needs of a particular application, but here are three equipment options that are commonly used to minimize dusting:

Conveyors
Tubular Drag, Screw Conveyor and En-Masse conveyor dust control solutions each feature a sealed design and are excellent choices for confining material to the process and eliminating dust particles. These systems are often even more effective with the introduction of dust hoods and dust collection systems at the entry and exit points along the line.

Central Dust Collection Systems
Comprised of larger, substantial dust control equipment, these systems are an obvious solution for capturing and removing particulates from the plant environment or larger processes. The primary disadvantage is that these systems remove the material from your process. They are not cost-effective for small operations and may not always adequately capture areas of concentrated dust particles in far corners of a facility.

Point-Of-Use Dust Collectors
These dust collectors are used, as the name suggests, at the point of dust creation. Assembled in a hood, which can fit on an existing mill or can be designed as part of the hammermill. When ingredient's are crushed, this integral dust collector immediately removes the airborne particulates by extraction or blowing the dust back into the mix. Blowing offer's the added benefit of containing expensive material that would be lost in a extraction collector.

Dust control and risk mitigation go hand-in-hand for manufacturers who process dry powders and other bulk materials. Getting a handle on this challenge by implementing some of the innovative safeguards available from Todd Augers & Equipment North Island can improve employee safety without diminishing profitability. Because as Benjamin Franklin also said, “a penny saved is a penny earned.”

Auger or screw conveyors easily move materials and offer valuable protection for other equipment. However, not just any auger conveyor can do the job efficiently. Todd Augers North Island provides professional help in the process of selecting and designing the perfect system. Here are some helpful tips on choosing industrial screw conveyors.

WHAT KIND OF MATERIALS ARE YOU MOVING?
When choosing auger conveyors, an important aspect is the pitch and flight of the conveying mechanism. Single flight conveyors are the most common, but some systems will use double flights. The pitch or angle of these flights can vary a lot, depending on the need. For most horizontal conveyors, single flight, standard pitch systems work best. In these units, the outside diameter is the same as the pitch.

FLUID-LIKE MATERIALS
When moving material like cement or fine powders, it’s best to use a single flight mechanism with a short pitch. This setup gives industrial screw conveyors a smaller distance between flights and keeps surging to a minimum because it slows movement down.

THICK OR STICKY MATERIALS
Thick materials tend to stick together or pack, so in those cases, a ribbon conveyor system works best. For example, ribbon-type auger conveyors move sludge and wet sugar super efficiently. This type of system prevents material buildup and can be designed to be shaft-less.

INDUSTRIAL SCREW CONVEYORS AND JAM-UPS
Dealing with a jammed up conveyor system is never fun, and good design can go a long way in eliminating the problem. No matter what type of material you need to move, even if it is thick or abrasive, we will have the right system for your facility.

Screw conveyors, also called auger conveyors, are used in processing plants for conveying food products. By designing certain features into the screw conveyor system, other benefits can be obtained. These include, temperature control, mixing of products, chopping of product, metering, dispensing, and more. Long term gains in both efficiency and quality are very possible. In fact, they are happening in numerous plants for which we have designed and built screw conveyor systems.

MUST-HAVES
The most obvious must-have in any sanitary screw conveyor is to provide for a fast, safe, simple wash-down. The first is to provide for a no-tool dismantle for wash down. Using hand tightening swing bolts on the end plates eliminates the need for hand tools and removable hardware. Secondly, the use of square drive components allows the drive to remain in place while removing the auger for cleaning, leaving one less thing to fool with. A third option is to build clean-outs right into the bottom of the trough. Of course, washing can be done while leaving the auger in place.

THERMAL SCREW CONVEYORS
Screw conveyors that either heat or chill the product while conveying offers huge benefits for some industries. An experienced design engineer has the knowledge to provide optimum thermal capabilities for the application. Thermal screw conveyors are currently in use in the food processing industry, specifically cheese and frozen food processors, the biofuel industry and more.

MOBILE SCREW CONVEYORS
Giving mobility to the auger is another great option for many situations. The screw conveyor may be mounted on a frame with heavy duty casters giving flexibility to processing plants. In one case, a plant was able to reduce product change-over and wash down from six hours to less than 15 minutes per day. In short, this replaced a carousel auger system with just two mobile thermal screw conveyors.

A commercial auger conveyor is an efficient way to move raw materials from one area to another with little to no spillage. However, screw conveyors can develop or create other problems. Here are some ways to keep your auger conveyor running smoothly, as we discuss common issues you may encounter.

COMBAT DUST PROBLEMS TO KEEP YOUR AUGER RUNNING SMOOTHLY
Dust in the atmosphere can be a serious hazard. It can make it difficult for people to breathe and may lead to respiratory problems. Also, some types of dust are combustible and can present fire hazards in the workplace. A great deal of dust is created with the movement of powders and finely ground materials. To to keep your auger conveyor running smoothly, ensure you’re utilizing the correct seals and gaskets. What may work for some materials may not work for others. One should consider gasket material which can be greatly compressed. Additionally, flanged covers may provide the kind of protection you need from dust.

CLOGGING
Auger conveyors can clog up when conveying wet or sticky materials. In this case, standard screw conveyors may not be the answer. One solution for this is to add gentle heat to the auger for better movement of material. Cheese is one material that slides much easier through a heated auger system. Another option is to go with shaft-less screw conveyors which can eliminate any clogging issues.

ABRASION
If your auger conveyor is working too hard to move the material, this can greatly add to the “wear and tear” factor of your conveyor system. Average carbon steel can quickly become worn down. In return, this will greatly reduce its life expectancy. One way to combat this is to use high carbon abrasive resistant steel alloys for increased toughness and hardness. Another option is the use of nickel-based alloys that with the addition of molybdenum and chromium for increased resistance to both abrasion and corrosion. The wood pulp industry finds benefits in conveyor equipment made of these alloys. The use of specially coated shafts and troughs is yet another way to resist the abrasion caused by these materials. By employing one of these methods of battling abrasion, a longer conveyor life, less downtime and fewer maintenance issues can be enjoyed.

CHANGING APPLICATIONS
If you are trying to make your old auger conveyor system perform work that it was not originally designed for, it can present several problems in the future. Instead of modifying and retrofitting, you may be much better off with a custom-designed screw conveyor system. Todd Augers & Equipment has years of experience with these systems. Thus, we take the issues you may encounter into account to keep your auger conveyor running smoothly.

]]><![CDATA[TYPES OF SCREW CONVEYORS]]>Wed, 08 Apr 2020 21:05:38 GMThttp://www.toddaugersnorth.co.nz/todd-augers-blog/types-of-screw-conveyors

The function of a Screw Conveyor is to push material as the screw rotates in a fixed trough, pipe or housing.

Using rotating helical screw blades (also referred to as flights or augers), screw conveyors appear in almost every industry and transport all types of materials. They consist of a tube or trough containing a helical screw blade, which transports material according to its rotational direction as driven by conveyor motors.

Conveyors come in many different types, screw diameters, and material-moving capacities per hour. Screw conveyors can provide precise volumetric material-moving control, which makes them appropriate for dosing applications.

Choosing appropriate screw conveyors relies on successful accounting of desired capacity, material particle size, viscosity, flow-ability, density, abrasiveness, flammability, toxicity, hygienic concerns, and chemical compatibility.

Screw conveyors benefit a wide range of applications, including:

Grain transport in agriculture applications
Metal chip removal systems
Food & Fishery processing plants
Flow control of plastic pellets in injection-molding operations
Powder dosing in the pharmaceutical industry
Cement mixing
Petroleum refining
Mining and mineral processing
Mixing, blending, and agitating materials or solutions
Conveying non-flowing caking materials

Characteristics of Screw Conveyors

Position
Horizontal Screw Conveyors
The most widely used conveyor type, horizontal screw conveyors move material depending on its characteristics at a range of 15–45% trough loading.

Operators use higher feed ranges for lighter, free-flowing materials, whereas lower feed ranges aid with sluggish, more difficult to move, and abrasive materials.

Inclined Screw Conveyors
Typically operating at angles between 0° and 45°, inclined screw conveyors transport and elevate material through different levels of your facility.

However, note that increasing the incline degree increases friction loss, thus reducing conveyor efficiency.

Sizing
Screw Conveyors are specified by:

Outside Diameter of Flighting
Pitch
Inside Diameter of Flighting. This is also the size of the pipe or tube the flights are mounted on.
Flight Thickness
Material
Overall Length
The direction of Flighting: Right or Left hand

Material
Screw material types include carbon steel, abrasion resistant steel, and stainless steel. Wear resistance can also be increased by adding hard facing material to the edge or the entire flight.

Type of Screw – With or without a center core

Screw Conveyor
Flights mounted on a pipe or tube. Typically screw does not contact the bottom of the trough. The screw is supported by bearing and hangers

Centerless
Flights are fabricated as a continuous ribbon. Typically center-less ribbon will ride in the bottom of the trough or tube. Often used with chip conveyors and sticky material
