Abstract
Paper mills produce large quantities of paper daily. In overall production per day, almost 10% of papers are rejected considering quality standards or other reasons. These rejected papers are called as Broke. This rejection takes place at each and every level of the production unit. The final rejection is in the finishing house where all the broke are collected together and fed into pulper as a process of recycling it. This particular pulper machine is a manual sequence process. It involves manual paper loading, valve operation, Agitating, Pumping etc. The ultimate aim of this project is to automate and control the above process by designing a control system using Programmable Logic Controllers. Thus a Cost Effective design can be implemented wherein the expected consistency of Output Pulp, high Precision in Broke Loading and a perfect time cycle oriented process can be achieved.
