Long term supply of second-hand sling centrifuge

A suspended centrifuge (also known as a hanging centrifuge or suspended basket centrifuge) is an intermittent filtration centrifuge. Its core feature is that the drum is vertically suspended from the frame through a suspension belt (or suspension shaft), driven by a motor to rotate, and uses centrifugal force to achieve solid-liquid separation. It is widely used in industries such as chemical, pharmaceutical, food, sugar, etc., especially suitable for handling materials with large crystal particles that require gentle separation.

1、 Structure and Working Principle

Core components:

Drum: A cylindrical or conical filter structure lined with filter cloth or mesh, used to hold materials.

Suspension system with suspension straps: The drum is suspended at the top of the frame through bearings and suspension straps to ensure smooth operation.

Drive device: The motor drives the drum to rotate at high speed through a belt or direct connection.

Unloading mechanism: manual or automatic scraper (or gravity unloading), used for the discharge of separated solids.

Shell and shock absorption system: The enclosed shell ensures safe operation, and the bottom shock absorption device reduces vibration.

workflow

Feed: When rotating at low speed, the material is evenly distributed into the drum through the feed pipe.

Separation: Under high-speed rotation, the liquid passes through the filter and is discharged, while solid particles are trapped on the surface of the filter cloth.

Washing (optional): Add washing solution to clean the solid residual mother liquor.

Unloading: After deceleration, the solid is discharged from the bottom or side of the drum by scraper or gravity.

2、 Main features

Gentle Separation:

The drum suspension design reduces vibration and is suitable for the complete preservation of brittle crystals such as sucrose and pharmaceutical intermediates.

Can control the speed to avoid material breakage.

Flexible operation:

Suitable for intermittent production, with adjustable processing capacity (single machine capacity ranging from tens of liters to several cubic meters).

Configurable multi-level program control (feeding, separation, washing, unloading automation).

Easy to maintain:

The open top structure facilitates the replacement of filter cloth and drum cleaning.

After separation, slag can be discharged to reduce cross contamination.

Low residue:

A high separation factor (usually 500-1000) ensures sufficient liquid removal and low solid moisture content.

3、 Typical application areas

Sugar industry: dehydration of sucrose and glucose crystals.

Pharmaceutical industry: solid-liquid separation of antibiotics, vitamins, and traditional Chinese medicine extracts.

Chemical industry: washing and drying of calcium carbonate, fertilizers, and dye intermediates.

Food processing: dehydration of salt, monosodium glutamate, and starch.

Environmental protection treatment: sludge dewatering, mineral particle recycling.

4、 Comparison of advantages and disadvantages

advantage局限性

Suitable for large particles and fragile materialsIntermittent operation, lower efficiency than continuous centrifuge

Simple structure and low maintenance costPoor performance in handling high viscosity or fine particle materials

Unloading with minimal residueThe labor intensity of manually operated models is relatively high

Closed design complies with GMP standards (pharmaceutical, food)Large equipment occupies a large area

5、 Selection and usage precautions

Key parameters for selection:

Material characteristics: particle size, viscosity, corrosiveness, solid content.

Separation requirements: processing capacity, moisture content target, washing requirements.

Material selection: The drum and filter screen should be corrosion-resistant (such as stainless steel, titanium, and plastic lining).

Operation optimization:

Adjust the speed and separation time according to the material, balance efficiency and crystal integrity.

Regularly check the integrity of the filter cloth to prevent filter penetration or blockage.

Highly corrosive media require the selection of anti-corrosion coatings or special materials.
