In this way, the influence of possible insufficient lubri NSK bearings reduce maintenance costs in the papermaking industry. Papermaking machine bearings operating under high-temperature conditions are vulnerable to problems such as fracturing of the inner ring, which can result in work stoppages. NSK bearings, with their long service life, superior resistance to inner ring fractures
Depending on the paper machine's design, some bearings may be lubricated with grease. There are specific greases formulated for these applications as well. They typically utilize a higher viscosity base oil (above 220 cSt), have high water resistance and are white so as not to impact the color of the finished product if any grease would. Compared to the other sections of a paper machine, the bearings in the reeler operate in a relatively good environment: dry and about 25°C. Still, these bearings must be protected from paper dust. Reelers are relatively slow-running machines, and in most of them grease is used on the reel-drum bearings
The bearings that are used in the dryer rolls of papermaking machines operate in hot environments because high temperature steam is passed through the rolls. The following are examples of the kinds of bearing damage that can consequently arise: early abrasion caused by insufficient formation of a film of lubricating oi Friction in the tend side bushing, Figure 15, resists the drive side loading and produces a constant twisting load on the can. Start/stop cycles of the machine, as well as paper breaks and rethreading, induce cyclic loading in the can. FIGURE 15: General View of Dryer Can Support Point Showing Oil Rag Box for Bushing on Can Shaft The purpose of a paper machine steam and condensate system is to control steam pressures for optimum drying, provide stable control over the entire operating range and efficiently remove condensate from inside the dryers. The comments below are a collection of performance tips for keeping your S&C system up & running at maximum capacity Effective, trouble-free doctoring is essential for modern, automatic and computer controlled paper machine operation. This ensures paper machine runnability and product quality. Doctoring is a relatively simple process but it is still important. It has three (3) basic functions in the paper machine: 1

The condensate is collected at the bottom of the dryer. Is the speed more than 350 m/min the condensate moves with the dryer. The reason is the friction between th
This Technical Information Paper (TIP) provides guidelines for inspecting cylindrical, steam-heated pressure vessels made from gray cast iron (GCI) and used as rotating dryers in papermaking. These guidelines also apply to unheated GCI cylinders of the same construction, but large yankee dryers typically used on tissue machines are not covered paper machine audits in the last decade. In the case of dryer section controls, tuning is difficult and the results are often inconclusive. This is because Of the complex dynamics of the dryer pres- sure loop, the potential for wide variation in these dynamics, the built-in non-linear- ities which result from the split ranging o Replacing a dryer bearing can be a challenging do-it-yourself job. If you do not replace the bearing once you notice the operation of the dryer beginning to falter, it can end up costing you a large amount of money in repairs. However, with the right set of tools and a good degree of patience, you can have your dryer working as good as new in. • The dryer's maintenance history, especially problems with bearings or internal components like siphons, balance weights and spoiler bars. • Operating conditions, especially if rotational speed or dryer section pressure are increased (rerated) cast iron paper machine dryers ). .
Paper Machine Clothing · Second Edition | 247 This chapter includes troubleshooting guides for the forming, pressing, and drying sections of the paper machine. Although it is difficult to list all possible causes for all machine types, these lists can be used to provide guidance in troubleshooting most equipment Because of the high temperatures in modern papermaking machines drying sections, the journals of the bearings in drying and Yankee cylinders are usually insulated. These cylinder bearings can experience temperatures reaching 125°C (257°F). Circulating oil is the best choice for lubrication. There are, however, potential pitfalls in the design. Present day papermaking machines use two wires, between which paper is formed in a much shorter time than is possible with the conventional machine. Water is pressed out of the paper in the press Bearings in dryer section have to be lubricated by means of oil circulation system

Over the last two decades, we have inspected thousands of dryer rolls following the industry standard for dryer roll inspections: TAPPI TIS 0402-16 Guidelines for the Inspection and Nondestructive Examination of Paper Machine Dryers . The TAPPI standard recommends the following types of inspection water from the paper by sucking it out of suspension. Multi-layer paper machines and paper board machines include additional forming sections (one forming section for each layer of paper). Forming section drives have a high friction load due to the suction (normal forces) of the water through the wire mesh. This results in a hig paper machine, or Yankee Dryer Roll. Magnetic particle examination of the dryer journals is used to detect cracking that could lead to a catastrophic in service failure. Ultrasonic straight beam testing of 20% of the head bolts on each roll is used to further enhance the effectiveness of the dryer roll inspection
Paper machine dryer section is for paper drying, there are two main aspects affecting paper machine drying efficiency: steam pressure and heat transfer coefficient. Paper Machine Drying Influencing Factors. Steam Pressure: In order to improve drying efficiency, the dryer temperature can be increased by increasing steam pressure, but the maximum. Drying concepts consist of a defined number of steam-heated drying cylinders in direct contact with the wet paper as it leaves the press section, which finally leads to a curl-free paper. The wet paper after press section contains about 50% water. For water removal, thermal energy (steam) is applied, causing the water to evaporate as it passes. 00:00. 01:17. On a paper or board machine, steam is piped to the inside of each dryer can, where it transfers its heat to the inside surfaces as it condenses into water. When hot condensate is dumped into a receiver at a lower pressure, some of the condensate will flash and produce steam. A desuperheater injects hot water into steam to lower.

Kadant Johnson is a global leader in the design, manufacture, and service of dryer drainage systems, rotary joints, syphon systems, and related equipment for the dryer section of the paper machine TAD (Thru Air Dryers) where air is forced thru the sheet as it passes over the dryer, and Yankee dryers which are large in diameter, thereby allowing the sheet to remain on one 'dryer can' for a longer period of time but yielding similar results as smaller dryer cans (heat transfer into the sheet, evaporating water from the sheet)
Well, the answer varies depending on the type of machine you have, and if the cost of hiring someone to come out and replace them. Generally, you can expect to pay between £100-£200 to change the drum bearings. It is worth assessing whether it makes more economical sense to repair the bearings yourself, or to purchase a new machine instead The Yankee dryer has long been considered the heart of a tissue machine. This massive pressure vessel serves a vital transport function, carrying the lightweight tissue sheet through the drying process with no open draws. It is the place at which most of the water in the web is evaporated while at the same time the crepe and structure are added.
Dryer drum slide. There are two of these needed on your dryer. These go on the inner most slots on the front bearing. Sold individually will need to purchase two*. The drum slides support the front of the dryer drum instead of rollers or bearings. As they wear out the dryer will make more noise Overloading can also burn out the machine's motor and bearings. When washing machines and dryers break down due to overloading, it almost always leaves behind tell-tale evidence that overloading was the problem. If your washing machine or dryer breaks due to overloading, YOU will have to pay for the repair. A lot of people who use washing.

drawn off over the width of the paper machine into the headbox. Stock leaving the headbox is made into a sheet by filtration. The fibrous mat is called a wet web, which is pressed, dried, and wound into a reel of paper on the paper machine. Paper machines may vary in width from about 5 to over 30 feet, and operate at speeds up to 1800 m/min The failure of a rotary dryer in a paper manufacturing facility is reported and analyzed. The primary cause of failure is identified as a weakened structure and as a consequence, inlet pressure of the steam into the dryer reaching a critical limit. Post failure, the shell, and the two heads of the dryer were analyzed using characterization techniques such as stereomicroscopy and scanning. machine reliability, reduce friction and power losses, and extend lubricant life. There are several reasons why bearings can be damaged or fail. Generally speaking,: 1/3 fail due to fatigue In the pulp and paper indus - try, for example, a major cause of bearing When paper web exceed press section of a paper machine, it contains more than half of its weight is water. Most of this water of the paper web should be removed in the dryer section of the paper machine to ensure 4%-6% of final water content. The drying section is one of the most energy consuming parts (about 60%) of the paper machine Machine speeds are also up and poised to increase even more after the next phase of the dryer improvement program is completed in November. That rebuild includes Turbulator bars and stationary syphons in the remaining 11 dryer cans and a new low-pressure steam supply system
The tub of the dryer is in constant motion while it is working. On the edge of the tub are glide bearings. Glide bearings buffer the tub from the sides of the machine and can cause metal on plastic sound and could be the cause of your squeaky dryer. These bearings are simple plastic or fabric tabs that can be easily replaced. How To Fix A. Machine surfaces can be hot because they are designed to produce or transfer heat, or because the friction created by machine movement has caused them to become hot. Some potential hot surfaces on a paper machine include steam lines, steam traps, pumps, and the motor on a forklift
