Centrifugal Vertical Dryer

Centrifugal Vertical Dryer

Often referred to as Centrifugal Dewatering Machine

The centrifugal vertical dryer is a machine that uses the principle of centrifugation to sieve the moisture from the material to dry it out. It consists of components such as hopper, centrifugal dumping body, discharge port and electric control box. It is the best choice for dehydration after washing plastics.

Centrifugal Vertical Dryer with more extras

A vertical centrifugal dryer is a type of industrial machine used for drying materials by centrifugal force. It’s commonly used in various industries such as chemical, plastics recycling and plastic pelletizing processing to remove moisture from wet materials.

All You Need to Know About Centrifugal Dryer

之前 之后

Centrifugal dryers are used in the plastics recycling industry, where cleaned plastic parts are placed into a hopper and transferred to a centrifugal drying chamber via a built-in screw conveyor, where centrifugal force is used to shake the material dry and lift it to the outlet, thus drying the material.

This article provides a guide to centrifugal dryers, discussing applications, mechanisms, factors to consider when purchasing and more. Read this article to learn more about the plastics recycling industry and centrifugal dryers to help with purchasing.

What Are Centrifugal Dryer Used For?

Centrifugal dryers are usually used in plastic recycling and pelletizing lines, usually in combination with shredders, washers or conveyors, for good drying results and a wide range of materials.

  • Pipe profiles
  • Plastic building materials
  • Plastic granulation
  • HDPE/LDPE Fragments
  • PET
  • PVC Fragments

Centrifugal Dryer Parts

Feed Hopper:

Made of stainless steel throughout. Used to collect materials to be dried, usually with a washing machine on the outside and connected to a screw conveyor on the inside.

Centrifugal Dewatering Machine
Screw Rods:

An important part of the screw transfer tube, connected to the hopper, the screw transfer tube has a stainless steel screen at the bottom for draining excess water during the transfer of the material to the centrifugal drying chamber.

Centrifugal vertical Dryer
Electrical Control Box:

Adopt Well-known 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.

Centrifugal vertical Dryer

It is like the heart of the centrifugal drying chamber, providing energy source for the paddle, using the famous factory motor and reducer, with high power and stable performance. Customizable drying capacity of 700kg – 2000kg per hour

Centrifugal vertical Dryer
Centrifugal Drying Chamber:

It mainly consists of a rotor and a stainless steel screen standing upright. When the material is transferred through the screw to the drying chamber, the screen in the drying chamber rotates at high speed and shakes the moisture out of the material just like a washing machine.

How Do Centrifugal Dryer Work?

A centrifugal dryer is a machine that uses centrifugal force to dry materials with moisture. When the material enters the hopper, the screw conveyor at the bottom of the hopper transfers the material to the screen in the drying chamber, driven by the rotor, the material rotates at high speed, just like a washing machine, and the moisture carried by the material is thrown out of the screen, completing the drying.


Why Choose Centrifugal Dryer?

Vertical construction for more space saving.

The moisture carried by the material is thrown off by centrifugal force rather than evaporating. Higher drying efficiency.

The centrifugal dryer can be used together with a variety of equipment before and after. For example: washing machines etc., FIBC bags or other equipment can also be used at the discharge of the machine.

Horizontal mixer do not cost much and last a long time. The minimalist structure is an important factor in the very low failure rate of centrifugal dryer.

Considerations When Buying Centrifugal Dryer

#1 What’s materials Size and density

The size and density of the material to be dried should be considered, too viscous or too small will result in poor efficiency of the drying centrifuge. Suitable screens and devices should be selected for different materials

#2 Production requirements

It is important to ensure that the centrifugal dryer is the right size and processing capacity for your line. Its drying capacity per hour, location and ease of cleaning are all factors you need to consider.

#3 the other function

As you know, one of our centrifugal dryers is combined with a water pelletizer, which is the perfect solution to the problem of plastic pellets being dried immediately after coming out of the water.
By combining as many functions as possible in one machine, the efficiency of your plant can be greatly increased. If you have similar requirements, please contact Nicety Machinery’s staff and communicate your ideas!

#5 body materials

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

Centrifugal Vertical Dryer
#4 The entire production line system

The centrifugal dryer is only one part of the equation. Considerations should include the requirements of the entire system. For example, location of discharge port, 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 Centrifugal Dryer?

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 centrifugal dryer.

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.
