High speed disc stack centrifugal natural rubber latex concentrate Liquid Solid Separation
The latex separator is ideal for separating and purifying natural latex, effectively removing solid impurities while dividing it into cream and skim. Its inverter start-up, electromagnetic brake, and short stopping feature make for a long and effective separating time. With a large treatment capacity and high separating efficiency, this separator is a top-of-the-line choice for latex production.
The natural latex, derived from the rubber tree, has a milk-white color and a solid content of 30%~40%. Its solid particles have an average diameter of 1.06um. Fresh natural latex contains 27%~41.3%(m/m) latex, 44%~70% water, 0.2%~4.5% protein, 2%~5% natural resin, 0.36%~4.2% saccharides, and 0.4% ash. In order to make it easier to transport and process, the natural rubber latex needs to be concentrated to a 60% solid content using methods such as centrifugation or evaporation. This type of concentrated latex is also referred to as “concentrated latex”.

Main Structure
This high-speed rotating drum is powered by a thermal coupling, with a powerful motor providing the necessary energy. Through a feed pipe located in the center of the drum, liquid material is carried into the bottom of the drum. From there, it is led through a porthole below the disc and driven towards the drum wall. Thanks to centrifugal force, a thorough separation occurs between the solid and liquid substances. The solid particles, being heavier, sink to the inner wall of the drum and form sediment. Meanwhile, the lighter liquid is carried through a centripetal pump and discharged through a liquid outlet. As for the heavier liquid, it is directed towards the cone inside the disc and then flows upwards through a heavy liquid concentric pump to be discharged from an outlet.
How does Disc Separator work?
The vertical disc separator consists of a motor-driven vertical axis with an upper-mounted, high-speed rotating drum. The drum is filled with a stack of disc-shaped components, with small gaps in between. As the suspension or emulsion is pumped through the feeding tube in the center of the drum, it passes through the gaps in the discs, resulting in sediment or liquid being separated by centrifugal force. The sediment then slides along the disc’s surface and accumulates in the drum’s largest diameter.
The outlet is where the liquid is finally discharged. The disc is designed to decrease the settling distance of solid particles or droplets, expand the settling area of the drum, and enhance the separator’s production capacity. The solids collected in the drum are removed manually after the machine is stopped, or taken out without stopping in the case of a dregs machine.
