It details the PM-7 machine operations, including pulp processing and maintenance practices, as well as the different types of pumps and bearings involved in the manufacturing process. Key insights encompass the manufacturing sites, operational capacities, and technical specifications that ensure efficient paper production.
Maintenance of Machine & Main Functioning Parts of Machine
- 1. Presentation Report On Industrial Training “Maintenance of Machine & Main Functioning Part of Machine” By Rohit G. Sorte
- 2. Covering Area • About Industries • Manufacture of Wood pulps • PM-7 Machine Working Process • Maintenance (Shutdown/Breakdown) • Pumps • Bearing
- 3. Profile • Bilt is a flagship of the us$4 bn Avantha Group. • India`s largest manufacturer of Writing and Printing Paper. • Bilt is largest exporter of Paper. • Bilt(Ballarpur Industries Limited) name changes to BGPPL(Ballarpur Graphic Paper Production Limited.
- 4. Bilt Has Six Manufacturing Unit in India 1. Ballarpur, Maharashtra 2. Yamuna Nagar, Haryana 3. Kamalapuram, Andhra Pradesh 4. Bhigwan, Maharashtra 5. Ashti, Maharashtra 6. Gaganpun, Orissa
- 5. logs •Wood blogs from forest De-barking •Process of removing bark from wood Manufacture of Wood Pulp
- 6. Chipper & washing •Chipping of wood and washing of wood to remove unwanted material like Sand Refiner Defibration •Separating of cellulose fiber
- 7. Bleaching •Used for whitening of paper Paper Machine •Pulp is turn into Paper
- 8. About PM-7 • Capacity of PM7 155000TPA • Deckle at Pope Reel 5.46mts • PM operating speed 1100 mpm • Budgeted of machine 525crs • GSM Range 54-90 gm/meter • Production 519TPD(60GSM, 1100m/min)
- 9. PM-7 Machine Process Details Sil Hydraulic Headbox Where many of the important paper properties are determined. Press Section Removal as much water as possible from the paper wet and compresses it. Wet pressing less a significant affect on paper properties(when the paper wet strength is good).
- 10. Dryer Section Water is removed from the paper by evoporation In dryer roll saturated steam is used There are 43 dryer rolls out of which 31 at predryer 12 at postdryer rolls. Vacuum Roll Water is removed from the paper by Vacuum pressure. There are 18 vacuum Rolls
- 11. Sizer The starch is applied on the both the side of paper to give properties for printing and writing paper. Steam consumption are achived
- 12. Soft Calender Roll Give surface properties like gloss, smoothness 2 sidedness monitoring & calliper profile. The machine is equipped with one heated cylinder and one (ACR) Adjustable Crown Roll.
- 13. “D” Reel It provide smooth reeling technique Winder The winder cut the reel into smaller rolls according to customer order.
- 14. Maintenance (Shutdown/Breakdown) • Job screening • Scoping • Availability • Planning • Schedule • Execution • Close-out
- 15. • Job Screening Priority of doing job Risk of doing job • Scoping Replace Repair Patch up Defer work
- 16. • Availability Availability of material Availability of man power • Planning Job tasks Labor management Cost estimate Safety
- 17. • Scheduling Time management Availability of material • Execution Work to do • Close-out Inspection of work Completing the job
- 18. Pumps • Pumps means conversion of mechanical energy to hydraulic energy. • Pumps are used to move Fluid.
- 20. • Dynamic pressure pumps ( thronging ) Centrifugal Pumps Fluid move from center to outer side
- 21. • Jet pumps Suction of fluid & rotation and discharge
- 22. Positive displacement Pumps It is Physical pushing
- 23. Positive displacement Pumps • Reciprocating Pump • Rotary Pump
- 24. Reciprocating Pump • Piston Pump • Diaphragm Pump
- 25. Piston pump Where Piston is used to give motion to the fluid by crank mechanism
- 26. Diaphragm Pump
- 27. Rotary Pump • Gear pumps A gear pumps which is used as a meshing gears, to pump the fluid by displacement.
- 28. Screw pump • A pump that raises water by means of helical impellers in the pump casing.
- 29. Lobe Pump
- 30. Bearing Basic principal of Bearing • Load Carrying Capacity and Life • Rigidity • Friction and Increases in Temperature • Speed • Lubrication • Design of Bearing arrangement
- 31. • Load Carrying Capacity and Life Rating life Load carrying capacity Operational reliability • Rigidity The Rigidity is determined by the type, size and operating clearance of the bearing.
- 32. • Friction and Increases in Temperature Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements. Sliding against each other increases in temperature • Speed The rate of change of its position
- 33. • Lubrication Important for reliable operation, long operating life, smooth working of bearing and to resist from corrosion. • Design of Bearing arrangement As per international standardization (ISO280) Requirement of machine.
