Natural Rubber Latex Disc Stack Centrifugal Separator

Introduction

The Natural Rubber Latex Disc Stack Centrifugal Separator is a high-speed disc-type centrifuge designed for the continuous clarification, concentration, and purification of natural rubber latex.

It uses disc stack technology to accelerate the separation of impurities, proteins, and water from latex, providing high-quality purified natural rubber latex for further processing.

The natural latex is from rubber tree, milk white , solid content is 30%~40%, and the average diameter of solid is 1.06um. The fresh natural latex contain latex 27%~41.3%(m/m),water 44%~70%,protein 0.2%~4.5% ,natural resin 2%~5%, saccharides 0.36%~4.2% and ash 0.4% . To facilitate transportation and processing, natural rubber latex should be concentrated to the solid content of 60% by adopting the method of centrifugal or evaporation. so it also known as concentrated latex.

Natural Rubber Latex Disc Stack Centrifugal Separator  is suitable for concentrating and purifying of the natural latex. It can separate the latex into the cream and skim, as well as eliminate the solid impurities at the same time. This model of separator is provided with the following advantages: inverter start-up, magnetic brake, short stoppin, and long effective separating time, large treatment capacity, good separating efficiency. It is really a excellent equipment for the latex production.

Technical Parameters

Working Principle

• Natural rubber latex is fed into the rotating disc stack bowl.

• Centrifugal force (often exceeding 10,000–15,000 g) drives the heavier water and impurities toward the bowl wall.

• The lighter rubber particles collect near the center and flow out as clarified latex.

• Disc stack design increases the settling area, enabling continuous high-efficiency separation.

• Solid impurities settle between discs and are discharged periodically or continuously depending on the design.

• This process allows latex to maintain stable viscosity and high purity, critical for downstream products like solid rubber, gloves, and latex foam.

Key Advantages

•High separation efficiency, ensuring low residual solids

•Disc stack design maximizes settling area

•Continuous operation, ideal for large-scale latex processing

•Stable product quality with uniform viscosity

•Corrosion-resistant construction (SS304 / SS316L), suitable for acidic latex

•Energy efficient compared with traditional centrifugal clarification
