The Australian construction industry will receive a significant boost in 2013 with the introduction of a new series of drum roller onto the market. Leading Chinese manufacturer Liugong is bringing to Australia the new CLG6118H, CLG6120H and CLG6142H compaction rollers, which have been developed to the highest western standards, and are designed and built to work in a variety of demanding environments.

The three new models, with rated working weights between 16,800kg and 23,000kg, are notable for the excellence of their engineering, and feature a combination of leading international technologies: they are powered by Cummins QSB6.7-C190 diesel engines, include hydraulic pumps and valves from Sauer, and are fitted with ZF axles. The operating width on all three models is 2100mm and there are three different drum diameters available - 1500mm, 1600mm and 1700mm.

These machines also feature a number of innovative design elements that represent significant developments in the areas of operator comfort and ease of maintenance.

They have a low overall height, and the cab is designed so as to give an operator 360-degree vision, aided by front and rear wipers, defrosting glass and an internal rearview mirror. It is fitted with ROPS and has low noise and vibration insulation, and also includes air conditioning, a sunroof and a rotary Grammer seat. The control assembly is well-located, as is the compaction meter, making the machine comfortable to operate for extended periods of time. Further, there is a unique double vibration reduction system, meaning these rollers provide a quiet, smooth ride (and which also contributes to the lifespan of components). Overall, the operator environment is designed very much with both safety and well-being at the forefront.

Drum roller are tough to clean. The drum roller of your toner printer can be cleaned and you might want to do that in order to increase its life cycle. In most cases a drum cartridge will last while using around 3 to 4 cartridges. After that, it will wear out. However, you can increase the life cycle through cleaning and this is something that you have to consider because the drum unit is quite expensive when compared to the toner cartridge.

Before we get started, remember that toner powder is dangerous because it is toxic until the transfer to paper is done. Handle it with care. Try to clean the drum roller when you notice:

    Faded text

    Paper marks or smudges

    Paper jams often appear

    Images have blank spots

    Powder or lumps appear on the drum

Once again, remember that when you try to clean the drum roller you can damage it in the event that you make mistakes. Do that at your own risk!

We recommend that you take a close look at the user guide that comes with your printer or look for the troubleshooting manual on the internet. This is helpful as you can see what the correct cleaning procedure is. Follow it and in the event that you do not find such information, follow the tips mentioned below.

It is recommended to use rubber gloves but washing or surgical gloves are also OK. Put a plastic sheet that is large on a surface that is flat. You can use a newspaper or a large sheet of regular paper. Open your printer and then remove your toner cartridge. Look at the drum to see if there is obvious damage noticed. In the event that you see such damage, replace the drum roller as there is no sense in cleaning it.

Put the drum roller on a newspaper or on the plastic sheet. Remove the toner spots that are large with the use of pliers or tweezers. Stay attentive to not scratch the drum's surface. Then, take a cotton swab and simply dip it in rubbing alcohol. Any visible soiling should be gently swiped with the cotton swab.

If you have a drum roller that is very dirty, take a lint-free cloth that is soft and drop some alcohol on it. Be careful to not add too much. Look for toner residue when the cartridge is out and also clean the interior of the printer if such areas are noticed.

When you are done, make sure that you let the alcohol dry and then reinstall the toner cartridge. Do a test run and in the unwanted event that you still have a problem, the only solution that remains is buying a brand new drum roller. In addition, if you notice that the drum needs to be replaced too often, you have to seriously consider buying a new printer.

No leaking allowed between the mixing material feeding port and the drum. The slack between the feeding port and the drum should be less than 5mm. If leaking occurs, repair it depending on the different mixer truck models. For example, for some models, just replace the wide rubber strap. And for some models, repair it by welding the thin steel plate with the size larger than a half circle.

1,fat choices:the choice of fat is generally selected based drum roller speed,temperature conditions,noise requirements and starting torque,etc.,require a variety of oils and fats business staff performance is very understanding.

2,the roller model selection:Roller type is normally provided by the user's technical staff to be selected according to the roller supporting products and bear the load conditions of use.Business people mainly know whether the actual load user selected roller match,if not up to the requirements drum roller,customers should be advised as soon as possible reelection models,but unless special products on select models generally do not have any problems.

3,the roller seal type choices:drum roller lubrication oil lubrication and grease can be divided.Oil lubricated bearings are generally used form of bearings,grease lubricated bearings generally use shields or rubber seals seal.Cover suitable for high temperature or use a good part of the environment,seals sub-contact and non-contact seal sealing two good contact seal dustproof performance but starting torque,non-contact seals starting torque is small,but the sealing performance no contact is good.

Roller surface contact stress at work is very big,so the quality of the roller and the bearing's life and the use of performance has an important influence.Practical application shows that the weakest parts in roller bearing is.

According to the different shapes can be divided into drum roller,roller taper roller,spherical roller and needle.

Although the shape of the roller is varied,but the same in the machining process,the general process for:metal pipe forming (cold heading,turning,forging)-or face soft grinding diameter-heat treatment quenching and tempering-end-grinding ball base (products when required)-coarse grinding diameter-fine grinding diameter-end mill diameter-grinding crown(products when required)-superfinishing diameter(Ⅱ magnitude precision roller).
Roller commonly used mechanical processing equipment are:the material transformation equipment,molding equipment,end face grinding equipment,grinding equipment,diameter of material transformation equipment is the auxiliary production equipment.

With the development of the theory of rolling bearing design,the structure of the roller also have new design,such as roller,roller with crown bus for logarithmic curve on the surface of the end face to the ball for cylindrical roller.The new design can improve the stress of roller,improve the service life of the bearing.At present,in view of the above design of roller processing and new technologies are:

Lean superfinishing method:it is developed on the basis of the ultra precision rectilinear,in changing the inclination of the ultra precision roller superfinishing,conscious of more than the two end of roller,forming outside diameter crown or logarithmic curve. 

Cylindrical roller base ball grinding method of selecting such assignment:it was borrowed from the processing principle of grinding spherical roller bearing outer ring of selecting such assignment.
