jaw crusher maintenance : pit & quarry

With proper planning and preparation, maintenance programs can be made easier and more effective. Importantly, operations can meet time management, cost savings and safety goals by employing good maintenance strategies.

So workers may take shortcuts that ultimately cost the operation more in the long run, Macini says. Crews need to be trained in the proper methods, and management needs to provide the support and resources to do the job correctly.

Cleanliness is key: Keep oil systems free of contamination. With a production, production, production mentality comes the attitude of, lets hurry up and change the oil. But crews dont bother to clean out any sludge buildup in tanks; and the new oil becomes contaminated.

Keep the breathers clean as well, and keep the right gaskets and oil filters on hand. Dont run oil filters into the red. Always have the right replacement parts and cleaning components set aside and ready to go. Be proactive, and remain prepared as oil-change intervals come up.

Keep the toggle area clean, particularly before any crusher adjustments. Its best to wash out the toggle seats and plates daily, as wet material buildup results in a gritty compound that grinds down components, causing premature wear.

Also, remove dirt and debris from crusher frame surfaces and from areas around the machine. Monitor discharge chutes for any obstructions and check for any material buildup under the jaw to avoid excessive wear on the pitman.

Conduct regular inspections: As specified by owners manuals, crews should follow the discipline of daily, weekly and monthly recommended inspections. While there are many inspection items listed on a manufacturers maintenance schedule, several are worth highlighting.

Check jaw dies daily, making sure bolts are kept tight. Check cheek plates for any excessive wear that may affect the mainframe of the jaw. Monitor flywheels for cleanliness, tightened bolts and potential cracks; and make sure drive belts arent worn or cracked.

Additionally, log your coast-down time daily. How long does it take the machine to come to a dead stop? If the time starts to shorten, this could indicate a bearing problem. Check all indicators and switches daily for proper operation as they are integral to proper shutdown in the event of issues such as high temperatures or low hydraulic pressures.

Dont over-extend wear parts: Avoid running jaw dies so long that they become too thin. You may find that you can no longer flip them over and now, youve lost half the wear. To get the full life of the manganese, change them out sooner than later.

Know the right fit for you: Consider that if youre an operation resigned to a less-than-the-best maintenance regime, youll be better off with a greased-versus-oil bearing machine. Requiring less-intensive maintenance than that of oil-lubricated systems, grease machines need a proper cleaning of the fittings and the application of the right grease. Applying the wrong grease (because thats whats on the shelf) is not an option, as this shortcut can ultimately cause equipment failure.

Update your equipment: As an example, Macini points to modern crusher designs that incorporate hydraulic tensioning cylinders that replace conventional toggle tension rods and springs. As a result, the tension cylinders automatically maintain the proper tension on the toggle, eliminating the need for spring adjustment. With proper tensioning being automatic, producers save time as well as reduce wear and tear on parts.

Furthermore, two oversized hydraulic cylinders behind a moving toggle beam enable all closed side setting (CSS) adjustments. A flip of a switch extends or retracts the cylinders and the adjustment is complete and made safely without shims being needed at any time. For safe toggle maintenance, the hydraulic adjustment cylinders push the pitman forward where it is locked into position with lockout pins, which insert from the side.

Then hydraulic tension cylinders, mounted on the side of the toggle, pull the toggle beam back, allowing it to be safely lowered away. Operations stress that this safety aspect is very important to them as they no longer need to have workers with wrenches climbing in, around or under this equipment, he says.

To prevent crusher damage, downtime and difficult maintenance procedures, the hydraulic overload relief system opens the crusher when internal forces become too high, protecting the unit against costly component failure. After relief, the system automatically returns the crusher to the previous setting for continued crushing.

He goes on to explain that typical older-style crushers may make use of a shear toggle that acts somewhat like a fuse. In other words, the toggle is a weak link that bends or breaks away when pressure becomes too great, and prevents further damage. But once the toggle is sheared or broken, the maintenance crew may have to spend up to four hours to remove and replace it, and that assumes the part is available.

Develop a maintenance discipline: So ditch the shortcuts. As with anything, you get out of it what you put into it. Learn to do maintenance jobs right the first time, and continue the discipline throughout the life of the equipment. The payoff is measurable in time and cost savings, and a far safer working environment.

maintenance of aggregate crushers | agg-net

Crushers operate at high power, force and capacity in order to produce the required materials. This puts a great deal of strain on the crusher and its wear parts, which operators must be aware of when carrying out maintenance. Failure to do so may have a big impact, both in terms of financial cost and potential loss of production.

Performing regular maintenance on crushers is integral to the reliability, performance and output they achieve. Prevention is better than cure; by carrying out regular inspections operators will ensure that their crusher runs for a longer period of time with minimal unscheduled downtime.

The most important aspect is to have a maintenance plan in place and execute it. Following a maintenance plan and carrying out daily inspections can yield increased service life. The plan should adhere to the recommendations of the manufacturer.

Maintenance plans may differ slightly depending upon the machine, but most follow an initial 40h schedule post commissioning, followed by regular 250h inspection/maintenance intervals throughout the annual cycle. Within these intervals there are prescribed tasks that an operator will need to carry out, including:

Where there have been insufficient maintenance inspections, the most common problem that Weir Minerals witness is premature bearing failure. For example, the operator may fail to notice that a breather has been knocked off, which fills the oil chamber with dust or debris; or they may overlook a grease line that has ruptured, causing the bearing to no longer receive the required lubrication; or they may not check the oil levels, resulting in a bearing failure due to a lack of oil.

For example, always ensure the wear parts are fastened into the machine properly. With jaw crushers, if the jaw dies are allowed to move during operation they can cause damage to the frame of the jaw crusher. Similarly, loose liners in cone crushers may damage the head or bowl.

Further to that, operators should track tonnages. As cone crusher liners wear, the operator threads the bowl inwards, bringing the bowl liner closer to the head, which reduces the feed opening. The reduced feed opening may decrease crusher throughput at a cost; once that cost is greater than the price of the liner change the operator should consider changing the liners. At a glance, the liners may still have what an operator would perceive as usable wear left, but at a loss of tonnage that does not benefit the plant.

Determining whether to stop production to change a wear part entirely depends upon the severity of the damage. For example, a damaged rotor tip in a vertical-shaft impact (VSI) crusher may make it through the shift and not cause unwanted downtime. However, a broken jaw die with parent steel exposed may cause significant damage, and it is vital that the operator stops the jaw crusher and changes the die in order to protect the crusherframe.

A common misconception is that operators think they should wear down jaw dies until they are completely flat or develop a hole or crack. By running these wear parts for a longer period of time, operators often think they are extending the wear life, but in reality they may be causing unnecessary stress to the jaw frame.

Another common mistake Weir Minerals have witnessed is that operators run cone crusher liners past their useful operational life. The resulting lost tonnages can cost the operator a great deal more money than the cost of a liner change.

Cone crushers have evolved from the earlier models introduced in the 1920s, with most manufacturers now designing cone crushers with advanced hydraulic systems to raise, lower and adjust the machines safely with minimal effort. To clear a cone crusher, users simply depress a button, click a mouse or toggle a switch. This removes the risk of people manually clearing a stalled cone crusher by hand or using straps, chains and rolling stock to adjust the crusher.

At Weir Minerals, safety is the number one priority and the companys latest designs reflect this. For example, the Trio TP cone crusher range is designed with self-protecting features to help achieve high levels of mechanical reliability under severe operating conditions, whilst ensuring the safety of both the operator and theequipment.

In addition, Weir Minerals latest Trio CTHT-series jaw crusher includes a hydraulic toggle relief system. This innovative, built-in system protects the jaw crusher from overloads caused by uncrushable material. The hydraulic toggle is designed to be a reliable and safe relief system, without any unnecessary complexity for the operator.

Operators who do not properly maintain their crushers may experience poor performance and decreased service life of the machines. It is suggested that operators seek expertise to create and execute a maintenance plan to increase the service life of their crushers. At Weir Minerals, the companys skilled service teams can provide professional on-site training for operators personnel to ensure smooth, safe and efficient plant operations andmaintenance.
