Pulping Chute


This Multotec innovation contributes to significantly lower costs and reduce downtime in your ore washing and scrubbing process. It is primarily used as a replacement for a scrubber in the secondary scrubbing modules.

The Multotec Pulping Chute scrubs ore material in a carrier liquid, liberating unwanted materials such as mud, clay, and slime from the surfaces of the ore.

With no moving parts, and by using the potential and kinetic energy of a slurry feed. The Pulping Chute provides mineral processing plants with a more efficient and cost-effective alternative to traditional scrubbing equipment and methods.

It features an inclined scrubbing launder, in which several slurry deflectors are positioned to create sufficient turbulence to liberate the unwanted material from the ore and to break up clay humps. These deflectors are optimised according to your ore and process characteristics for maximum scrubbing efficiency.

A modern scrubber alternative

Fines scrubbers contribute significantly to capital, operating and maintenance costs of a mineral processing plant. Scrubber operations require large power supplies, and significant mechanical component maintenance, lubrication and costs of replacement. By simplifying this process, operations can become more cost-effective and improved plant availability.

Pulping Chute additional benefits

Some of the advantages of the Pulping Chute over a conventional scrubber include:

  • Scrubber drive motors normally range from 200 to 600 kW depending on the size of the installation. Pulping chutes require no external power to operate. Material movement and washing is achieved using potential and kinetic energy.
  • Maintenance costs will be noticeably less than a scrubber installation which operates with complicated drive mechanisms and demands regular maintenance causing plant downtime.
  • Scrubber linings must normally be replaced on an annual basis whereas the pulping chute liners could be repaired as-and-when required simply by removing and replacing of chute sections on a service exchange basis.
  • Scrubber drives using rubber wheels are prone to slippage under wet conditions resulting in production losses and shell wear
  • Removal of a scrubber requires expert rigging and well-trained rigging crews whereas small sections of the pulping chute can be replaced during normal maintenance periods.
