Screw Press Separator Parameters

Tianzhong Machinery has single-screw press and double-screw press dehydrators for sale, which can lower the water content of the dewatered solid to about 60%. In a double screw press, there are two screws installed in opposite rotational directions. This kind of machine is effective for handling materials with high fiber content, such as sugarcane, herbal residues, vegetables, and more. However, the single screw press machines have a single screw that rotates in the same direction as the shaft. They are suitable for materials with relatively lower fiber content, such as fruits, aloe vera, etc. Below are more parameters for your reference.

Tips for Choosing Screw Separator Machine

When choosing a screw dehydrator, consider the following tips to help you select a suitable equipment:

1. Material Characteristics: You need to consider factors such as fiber content, particle size, moisture content, viscosity, and other requirements. These factors determines to choose single or double screw press, screen mesh size, etc.

2. Processing Capacity: Please confirm how many tons of material you need to process per hour to determine the required processing capacity of the screw press dehydrator.

3. Customization Options: Expect for screw types and screen mesh sizes, Tianzhong Machinery also offers customized options to meet your specific requirements. For example, you can choose a conveyor or shredder or other accessories according to your needs. Moreover, our equipment allows adjustments to parameters such as pressing force, moisture content, etc. to optimize the process for your particular materials.

By considering these tips, you will make an informed decision when choosing a screw press separator that best suits your needs. If you need help, please feel free to talk with us.

Applications of Screw Press Separator

Screw press separators have a wide range of applications in various industries. Some of the common applications include:

1. Wastewater treatment:

Screw press separators are extensively used in wastewater treatment plants for dewatering sludge, slaughterhouse wastewater, and biogas slurry.

2. Manure management:

It is also widely employed in farms for the treatment of animal manure such as pig waste, cow dung, chicken manure, etc.

3. Agricultural & food processing industries:

This machine plays a crucial role in extracting juice from fruits or vegetables, such as grapes, gingers, and more. In addition, it is also used to process fruit and vegetable waste or agricultural waste, such as sawdust, crops, straw, distillers’ grains, cassava residues, grass, and more. Moreover, this machine is an indispensable pre-treatment device for drying materials. It can efficiently remove excess moisture, leading to higher production output and speed, and lower energy consumption.

Overall, screw separator is versatile equipment suitable for the treatment of various organic waste and wastewater. It offers high efficiency, simple operation, and low maintenance. More importantly, it recycles waste materials into wealth while minimizing negative environmental impacts. If you are interested, please contact us for more details!

Parts & Structure

Below is a picture showing the main parts of a screw separator machine from Tianzhong Machinery. Let’s review their functions.
1.Inlet: It allows the raw material to enter the screw press. It may use a pump to ensure a consistent flow of the material mixture into the screw press, such as animal manure, biogas slurry, paper pulp, and other materials.
2. Auger/Screw Conveyor: The auger or screw conveyor is a rotating spiral-shaped component inside the press. It will transport the material from the inlet to the outlet while squeezing the water out. The screw design may vary depending on the specific material.
3. Screen: The screw conveyor is typically enclosed within a cylindrical screen. It allows liquid to pass through while retaining the solid particles. The screen mesh size determines the separation efficiency. The common mesh size is 0.5mm, 0.75mm, and 1mm. You can choose according to the material you process.
4. Reducer: The reducer is a mechanical device that is used to reduce the high-speed rotational motion of the motor to a slower speed to suit the screw conveyor.
5. Motors: There are two motors, one of which is for pump and the other one is used to drive the screw conveyor.
6. Waste Water Outlet: This is where the separated liquid exit the screw press.
7. Solids Discharge System: This is where removes and discharges the dewatered solid cake.
8. Control System: A control system aims to monitor and regulate various operating parameters such as feed rate, screw speed, and dewatering efficiency.
