Screw Conveyor

Often referred to as Screw Feeder

A screw conveyor is a type of conveyor with a spiral structured tube that allows materials to be transported over short distances by “spiraling up/transferring” inside the tube. Screw conveyors in modern industry are usually used at a slight incline. They are used in many bulk handling industries.

Different styles of Screw conveyor

A screw conveyor is a mechanism that uses rotating screws to move groups of material. The screws in the device go around at some predetermined speed, so they can be used as an inexpensive way to transport semi-solid materials over relatively short distances, such as plastic granules, feed or wood chips etc.

All You Need to Know About screw conveyor

The screw conveyor is a type of conveyor that uses a spiral shaped tube to move materials. The screws in the device go around at some predetermined speed, so they can be used as an efficient way to transport semi-solid materials over relatively short distances.

Spiral conveyor has many advantages, automation, can be highly efficient to transfer materials from low to high, instead of manual, for the whole production line automation to provide convenience.

What Are screw conveyor Used For?

NICETY are custom-made to fit your specific application: Whether it is the diameter of the pipe or the transmission efficiency (Ton/Hour). Plus, they’re perfect for use in a variety of industries:

Screw Conveyor Parts

Hopper:

Made of stainless steel metal, square or rectangular, for loading the material to be transferred. The hopper is inclined at a certain angle to match the rotation of the bottom screw.

Conveyor tube:

The internal matching screw has been used for screw rotation to transfer material. The screw is made of high quality stainless steel, which is strong and durable. In addition, the diameter of the transfer tube can be customized according to requirements

Moter & reducer：

Like a heart, it provides constant energy for the screw to rotate, and with the reducer, it can provide different rates of transmission speed

Material Outlet:

The whole machine can choose 201 stainless steel or 304 stainless steel production, can also be used according to demand more A3 steel to reduce costs.

Electrical Control Box:

Adopt ZHENGTAI brand, each function is clear at a glance. A variety of questions alarm function, the operation is more humane. With the motor overload protection function.

Wheels:

Facilitates moving screw conveyors. Wheels with snap-lock provide stable support for the conveyor while it is working.

discharging spot：

For the discharge of transferred material, connected to other equipment, e.g. silos, extruders, mixers, granulators, crushers, etc.

How Do Screw Conveyor Work?

Why Choose Screw Conveyor?

Totally enclosed for dusty, corrosive or hazardous environments

Cost-effective when compared to other conveying devices such as belt, pneumatic or aeromechanical.

Screw conveyors can be used to move a wide variety of materials, including both liquids and solids.

Screw conveyors can be used both indoors and outdoors, making them a versatile option for many businesses. Ideal for conveying dry to semi-fluid bulk materials – free flowing to sluggish

Considerations When Buying Screw Conveyor？

#1 Height

Screw conveyors are often used in conjunction with other equipment such as silos, mixers, extruders, crushers, etc. You may even need to transfer material from the first floor to the second floor of your plant. You may even need to transfer material from the first floor to the second floor of your plant, so the height of the conveyor is something you need to consider when purchasing. production needs.

#2 Transmission efficiency

3ton/hour? 5ton/hour or 10ton/hour? There are many factors that affect transfer efficiency, such as the power of the engine, the diameter of the transfer tube and the size of the screw. When you tell your requirements to NICETY’s sales staff, we will customize a cost-effective conveyor for you based on our years of experience.

#3 Additional Features

In addition to providing you with high performance vertical mixers, it is also important for NICETY MACHINERY’s staff to understand your additional needs and integrate them with the mixer, for example, with heating function or increasing the number of feed opening, or reducing the height of the opening to meet the use with other equipment, etc.

#4 body materials

Can be made of different materials according to your requirements, such as: A3 steel, 201 stainless steel, 304 stainless steel, etc.

#5 The entire production line system

The screw conveyor is only one part of the equation. Considerations should include the requirements of the entire system. For example, the purpose of the production system is related to the suitability of the material.

Types By Material

Which steel is the best materials for you to use to produce your screw conveyor?

201 stainless steel

Although the corrosion resistance of 201 stainless steel is not strong, but it still has good anti-corrosion properties, if your material is not strong corrosive, then the affordable 201 stainless steel will be the material of choice for the manufacture of screw conveyor.

304 stainless steel

304 stainless steel is a common type of stainless steel in life, the household appliances you use and even the faucets may be made of 304 stainless steel. It has better corrosion resistance than 201 stainless steel

More Options

Depending on your use scenario, there are many options for steel. If your product is a very corrosive chemical, the more expensive 316 stainless steel is obviously more suitable, and although expensive, it is worth it.
