Screw Manufacturing

Screw manufacturing refers to the process of producing a device, known as a screw conveyor, which facilitates the movement of powder and granular liquids through mechanical rotation inside a tube or trough. While mechanical transport (such as screw conveyors, bucket elevators, etc.) is often considered challenging and prone to corrosion, it is a more economical solution from an electrical perspective. Although screw conveyors are not typically preferred due to long-term investment costs, their operating costs are quite low.

Screw conveyors can function as feeders, conveyors, or feeding conveyors depending on the type. If a screw conveyor remains the same and is fed with the same power, it can process and feed raw materials. This concept is generally valid for "O" type screw conveyors. The power of a screw conveyor is proportional to the pitch of the helical blades and the rotation speed of the motor. All the screw conveyors we manufacture are designed according to CEMA standards. These standards include important factors such as bearing, safety measures, transport standards, and plate thicknesses.

What is Screw Manufacturing?

Screw manufacturing is one of the most important standards to consider when constructing or purchasing a conveyor. It is a set of standards that must include critical components such as bearing, feed screw type, and other factors that determine the type of screw, such as process conditions and the density of solid-liquid or granular raw materials.

What is a Screw Conveyor Feeding Repeater System?

In some processes, screws are not used with a specific angle. In such cases, horizontal and vertical spirals with different rotations are used in connection. These spirals work in pairs. Despite appearing separate, they form two different cochlear systems that work together. At this point, attention must be paid to the operating mechanism of the spirals, as improper operation can cause damage to the coils. Therefore, these augers are controlled with minimal automation, sensors, and conditions. The operational parts of these spirals are constructed either underground or above the ground.

What is Pull Screw Manufacturing?

Pull screws are used in the transportation of products and are also referred to as lead screws. These pull screws are sold without shafts and come with both right and left turns. Custom manufacturing can be done according to the given measurements. For screw manufacturing, thicker spirals are especially produced for more challenging conditions. Steering screws are manufactured with both right and left turns. When following the thread from the initial point, if your hand continuously turns right, it is a right-threaded screw; if it continuously turns left, it is a left-threaded screw.

The diameter distribution remains the same, but we can produce spirals with different diameters and pitches if desired. Coils are usually rolled unless they are made in very special sizes, which is particularly useful for transportation. Standard and some special sizes, especially coarse and chrome screws, are always available in our stock.

What is Flexible Screw Manufacturing?

Flexible screw conveyors are particularly useful for short distances and serve as conveyors, especially for free corners at jump-out exits. The length can go up to 10 meters without a wheel. These are highly efficient for powder materials, but may not be as effective for granular structures and different materials. They can be rotated by 90 degrees with an R=3000 mm radius. They work on non-wearing materials such as PVC dust, PP, PE, flour, sesame, cocoa, etc. They play an active role in processes such as filling and unloading large sacks, as well as feeding silage from bunkers. They are used, particularly with low capacity, with a maximum capacity of 5m³/h.

What is Flexible Screw Usage?

Flexible screws are easy to use, but they have different criteria depending on process conditions, operator use, idle status, non-closed exits, and hygroscopicity. Manufacturers, such as our company that produces screw conveyors, often point out that the use of flexible screws is easy and does not damage the product. However, neglectful situations should always be addressed and responsibly answered. This is important due to the responsibility we have for our process solutions and the work we do. These negative situations should be considered as follows:

Flexible screw enclosures are food-grade, but due to their fast operation, holes can form due to friction on the plastic casing. If the plastic is used for processed food, there will be signs of mixing. Moreover, the friction causes holes to form in the plastic frame. For this reason, it is not recommended for food processing.
