Medium Consistency Pulp Cleaner
What is Medium Consistency Pulp Cleaner
The medium-consistency pulp cleaner is a pulp purification and slag removal equipment in the pulping system. It uses the different proportions of fibers and impurities to make iron filings, broken glass, sand and other heavy impurities and air, plastic sheets, foam, paraffin, stickies, etc. Light impurities are separated from the pulp to achieve the purpose of purifying the pulp. It can also be used to purify low-concentration pulp before the paper machine.
Benefits of Medium Consistency Pulp Cleaner
Medium consistency pulp cleaners are highly effective at removing heavy contaminants like sand, metal particles, and other debris from pulp, improving the overall pulp quality.
Due to conical shape easy vortex formation with strong centrifugal action. They help retain more usable fiber by minimizing fiber loss during the cleaning process.
Minimum floor occupied due to its planetary design. Improves quality of the pulp stock for further performance. Number of bottles can be installed in planetary or in series form for different stages.
The medium consistency pulp cleaner is provided with two pneumatic valves with a junk trap between them. The valves operate automatically with PLC control.

How Does a Medium Consistency Pulp Cleaner Work?
The medium consistency pulp cleaner operates at a consistency range of 1.5%-2%. The centricleaner bottles are arranged in a planetary system with an inlet header beyond the center. This allows distributing the pulp stock evenly to all centricleaning bottles at constant pressure. The accept of all centricleaner bottles are collected in a planetary manner at the center. The rejects are is collected in closed-loop in the reject header that is directly connected to the reject pump feeding to the secondary stage cleaner. The Deaeration system is used to remove excess air from the pulp stock.
The Difference Between High , Medium and Low Consistency Pulp Cleaners
High consistency pulp cleaners, designed to efficiently remove heavy contaminants like sand, grit, and metals from pulp slurries. They are widely adopted due to their ability to enhance pulp quality and increase production efficiency by reducing wear and tear on downstream equipment. It has a simple installation process and protects further screening and refining equipment from wear and abrasion.
Medium consistency pulp cleaners, focusing on removing medium-weight contaminants such as staples, dirt, and small stones. Medium consistency pulp cleaner is used for cleaning of all typed of recycled papers and virgin pulp. It helps in increasing the life of screen baskets and improves deinking efficiency. These cleaners play a crucial role in maintaining pulp cleanliness standards, ensuring smoother paper production processes.
Low consistency pulp cleaners, specializing in removing lightweight contaminants such as ink particles, shives, and plastics. They are essential for fine-tuning pulp quality before it undergoes further processing. Stock preparation processes also leverage a combination of high and medium-consistency cleaners to ensure optimal fiber suspension and flow consistency.
Material of Medium Consistency Pulp Cleaner
The medium consistency pulp cleaner is made of stainless steel and ceramic. The inner wall of the cleaner is designed as a spiral cone. Medium consistency pulp cleaners are used in the pulping system to purify pulp and remove slag. They use the centrifugal principle to separate light impurities from the pulp. The heavy impurities, such as sand, iron filings, and broken glass, are thrown to the wall of the vessel by the centrifugal force.
Components of Medium Consistency Pulp Cleaner
The bottoms of primary bottles are built with ceramic cones for improved life and efficient separation of heavy contaminants.
Flexi glass with quick-release fitment is provided between bottom ceramic cone and reject header for easy cleaning of nozzles.
Dilution in the middle of the cone is provided to increase the centrifugal action at the bottom of the cone that increases the efficiency of cleaners.
A secondary stage cleaner is provided within the Built-in Tertiary Stage, and an Auto flushing system is in the reject chamber for fiber recovery and efficient disposal of heavy contaminants from the system.
What is the Typical Pulp Consistency Range for Medium Consistency Pulp Cleaners?
Medium consistency pulp cleaners operates at consistency range of 1.5 to 2 % against normal cleaner range of 0.6 to 1 % consistency. These cleaners are designed to operate efficiently within this range to effectively remove contaminants such as sand, dirt, and other heavy particles from the pulp. Operating at medium consistency helps optimize the separation process, ensuring high cleaning efficiency while maintaining energy and resource conservation.
5 Keys to Better Pulp Cleaner Operations
Understand the importance of hydraulic capacity
It is important for mills to pay close attention to hydraulic capacity because it has a direct impact on washing performance. The hydraulic capacity indicates the filtrate flow passing through the washer. If the amount of the filtrate flow passing through the cylinder and discharge assembly is too great, the discharge consistency and overall washing efficiency will be reduced. Reductions in discharge consistency and washing efficiency occur when there is not enough filtrate being removed from the pulp. More filtrate left in the pulp mat means more lignin and other solids are left behind, resulting in lower quality pulp being discharged from the washer.
Get to know your filtrate
The filtrate flowing around and through the vacuum washer is a very important aspect of pulp washing. Specifically, the impact of the speed of the filtrate on vacuum has an impact on performance. The velocity filtrate flow down the drop leg can affect the performance of the washer and should remain within a certain range to maintain the desired amount of drop leg vacuum. Lower velocities lead to lower drop leg vacuum. Lower levels of drop leg vacuum make it more difficult to pull filtrate through and out of the pulp mat, thus reducing washer efficiency.
Monitor discharge consistency
The discharge consistency of the pulp mat is a key data point because it is used for determining things like the dilution factor, hydraulic loading, and estimated drop leg flow. Each of these measures are used to determine a washer’s performance at any given point in time. To properly monitor discharge consistency, it is common to take one discharge consistency sample per shift from each washer, or from the final washing stage of a brownstock line during normal operation.
Beware of pulp mat re-wetting
Pulp mat re-wetting occurs when the filtrate pulled out of the pulp mat spills out of the drainage channels (underneath the decking) back into the pulp mat. Re-wetting reduces the discharge consistency and washing efficiency.
Perform regular maintenance
Regular maintenance of pulp cleaners and surrounding equipment is necessary to keep the process operating at peak conditions. This includes inspecting and, where necessary, replacing key wear parts such as discharge valves, valve assemblies and the seal chamber in the filtrate tank.
How to Maintain Medium Consistency Pulp Cleaner
Ensure that the operating pressure of the cleaner stays within the recommended range specified by the manufacturer. Excessive pressure can cause wear and damage, while low pressure can reduce the cleaner’s efficiency.
Inspect critical wear components such as cones, liners, and reject nozzles regularly. Any signs of erosion or wear should be addressed immediately by replacing the worn parts to maintain optimal cleaning efficiency and to prevent breakdowns.
Lubricate moving parts such as bearings and seals according to the manufacturer’s guidelines. This helps reduce friction, prevent overheating, and prolong the life of mechanical components.
