Medium-Density-Cleaner

Medium Density Cleaner

  1. The Medium Density Cleaner (MDC) is a centrifugal cleaner, similar to the High-Density Cleaner (HDC), and operates at a maximum consistency of 2-2.5%.
  2. It is installed after the coarse screening stage to remove heavy contaminants like coarse sand and other impurities.
  3. The working principle of MDC is similar to that of the HDC. After coarse screening, the pulp stock is fed into the MDC, where the tangential inlet accelerates the stock, creating centrifugal action.
  4. This centrifugal force pushes impurities downwards, while a fiber saver unit prevents fiber loss to the drain.
  5. The clean stock rises through the vortex center and is discharged via the central discharge pipe.

Benifits

  • Highly effective in removing contaminants such as glass, coarse sand, pins, staples, and more.
  • Can be installed prior to fine screening and de-inking stages.
  • Conical shape enables easy vortex formation and strong centrifugal action.
  • Simple installation and maintenance process.
  • No power consumption required.
  • Compact planetary design occupies minimal floor space.
  • Enhances pulp quality for improved performance in subsequent stages.
  • Multiple units can be installed in series or planetary configuration for different stages.
  • Equipped with two pneumatic valves and a junk trap, automatically operated by PLC control.
