IPPTA BEST MAINTAINANCE PRACTICES IN PULP AND PAPER INDUSTRY TO IMPROVE PROFITABILITY • Arial font to be used • Round dots to be used for bulletpoints Amol Deshmukh GL&V India Pvt. Ltd., 18 July 2014

OPEN LOOP, CONVENTIONAL CENTRICLEANERS

CONCERNS IN OPEN LOOP, CONVENTIONAL CENTRICLEANERS Need of individual cleaner feed and accept valves Open reject pit Fiber loss from Reject Pit spills & overfows Air intrapment from open reject vertex Larger parts for replacement (high cost) Heavy maintenance time & cost

CLEANPAC 700 LD

CLEANPAC 700 LD – Advantages Satellite assemblies Smaller replaceable parts Twin wall design Large cleanout plug Transparent reject chamber Transparent lower cone and lower shell Low density reject removal system

SATELLITE ASSEMBLIES Design flexibility Installations in smaller space In spite of compact design enough maintenance space Quick and easy replacement of complete cleaners and spares

SATELLITE ASSEMBLIES

SMALLER REPLACABLE PARTS No need of changing complete cleaners Smaller parts can be changed if damaged or worn out Parts assembled with O rings and clamps. Quick and easy replacement of parts Less time and manpower required for Maintenance CLP 700 LD Assembly

TWIN WALL DESIGNTM Well proven design Fig A – leakage through shell vent Fig B – Protection plug sealing the vent No immediate shut down for maintenance No pulp splash if inner cone worn out in running (FIG A) (FIG B)

LARGE CLEAN OUT PLUG Lower risk of clogging of reject pipe Large outlet minimizes risk of clogging caused by oversized particles Easy access to inside from bottom to clean and flush the cleaner

TRANSPARENT REJECT CHAMBER Visual access to reject transfer Large clean out plug Easy inspection of the individual cleaners for clogging

TRANSPARENT LOWER CONE AND LOWER SHELL Visual access to complete lower cone assembly Helps to understand the flow pattern and running condition of individual cleaners Proved to be very helpful in high reject containing pulps and critical cleaning applications

LOW DENSITY REJECT REMOVAL SYSTEM CLP 700 LD cleaner removes low density rejects from pulp like Plastics Hot melts Stickies Waxes Free air

CELLECO TWISTERTM

CELLECO TWISTERTM Satellite assemblies Smaller replaceable parts Twin wall design Operating consistency of up to 2 % Transparent reject tip Transparent lower cone and lower shell

COMPARISON OF CLEANERS LOW V/S MEDIUM CONSISITENCY NO. OF CLEANER UNITS PRIMARY SECONDARY TERTIARY FIBERMIZER TWISTER 9 2 1 CLP 700 18 6 Less number of cleaner units per stage Fewer Stages for bigger plants Less maintenance cost
