Optimised separation industrial centrifugal decanters

Multotec’s industrial centrifugal decanters enable fast and accurate centrifugation in mineral processing, operating on the counter-flow principle. Suspension is introduced to the centre of the bowl for separation and sediment is then conveyed via the scroll, which continuously rotates at an altered speed to that of the bowl. This results in clarified liquid flowing from the bowl’s large diameter opening.

The centrifugal decanter range includes the TS Industrial Decanter Centrifuge, DZ Industrial Decanter Centrifuge and DZS Screen Decanter Centrifuge. All of these centrifuges:

  • Reduce thermal drying and other processing costs
  • Increase separation efficiency for particles of all sizes
  • Have a compact design that facilitates use in small operating areas
  • Reduce waste with optimised separation

Frequently Asked Questions

What is solid-liquid separation?
Solid/liquid separation is the separation of solids from a liquid solution. The process involves the crystallisation of solid particles present in the liquid solution under specific conditions of an optimal temperature. If the heat is increased beyond a specific temperature, particles will evaporate and decompose.
How can you separate solid and liquid waste?

Methods to separate solids from liquids include sedimentation (solids settle by gravity); and mechanical separation. Gravity and mechanical separation are the two most common techniques used. Multotec manufactures and installs a range of products and solutions for solid-liquid separation. These include, but are not limited to, Filter Press; Industrial Centrifuges; Clean-iX® for Metals Recovery; and CIF® for Process Water Treatment.

What are the advantages of solid liquid separation?
A major benefit of solid/liquid separation is the improved efficiency of washing and isolating solids in complex synthesis processes. Benefits of using solid-liquid separation equipment from Multotec include
  • An increased separation rate, overall process efficiency, increased energy efficiency & minimal waste
  • Reduced capital and operating costs
  • Increased environmental compliance
  • Prolonged equipment life & improved safety
What equipment separates solids from liquids?
The centrifuge separates solids from liquids using centrifugal forces greater than the force of gravity. Other equipment used to separate liquids and solids is also provided by Multotec. In addition to industrial centrifuges, the Multotec range consists of filter press; clean-iX® for metals recovery; and CIF® for Process Water Treatment.
Which solutions are more effective in separating solids from liquid?
An insoluble solid can be separated from a liquid more efficiently using filtration. Filtration can separate solids that are also lighter than the liquid and it is faster. Filter cloth from Multotec includes lightweight to heavy-duty filter cloths that are either woven or felted according to application requirements. Multotec’s filter cloths are made from synthetic and natural fibres, tailored for your exact separation requirements.
