When need to change cone crusher liners?
To avoid damage to the liner seating surfaces of the crusher head or dish, wear parts must be replaced before they are put on through. In regular conditions, around 50% of the liner weight is taken in when linings are worn out. It is very important to keep a document of liner wear in order to analyze the level of liner wear without the requirement to stop the crusher operation. See the following guidelines
1. On the initial set of new linings, put a mark on the change cap chauffeur ring where the pinion tooth reaches a chauffeur ring tooth when the target crusher setting has actually been achieved.
2. Keep an exact record of the variety of teeth made use of to compensate for liner wear on this set of liners.
3. After the preliminary set of liners have broken, yet prior to moving the dish, document the total number of teeth the vehicle driver ring has actually relocated as well as likewise paint a horizontal liner on the side of the dirt shell just below the bottom of the modification cap. This will certainly be the standard for determining just how close the next liner sets are to being worn.
4. When a new liner set has actually been installed, keep a document of the number of teeth the driver ring has relocated as well as contrast this number to the overall number from the preliminary collection of linings. This will certainly offer an evaluation of the liner wear. The straight mark painted on the dirt shell will certainly also indicated when the linings are approaching the wear limit. The approximate minimum elevations of the changing cap (A-dimension) with worn liners are noted in the connected tables. When changing linings and also identifying liner wear, follow the instructions in the relevant Nordberg HP cone crusher instruction manual. Manufacturing considerations might often prefer altering of wear parts prior to they are completely made use of. Hourly capability or product quality may decrease toward the end of the liner wear life and it might be more cost-effective to change before the end of the liner wear life.
Typically, altered wear accounts can cause a decrease in capability. Other symptoms of badly wearing liners are high power draw and also ring bounce. Also, the wear life can be reduced since the wear is occasionally concentrated in a tiny area instead of spread along the full dental caries and the cavity might have to be changed prior to they are totally worn. This causes bad use and a higher operating wear cost.
How to change cone crusher liners?
There is a maximum time to alter your cone liners. Ahead of time as well as you do not get the worth for the price of the liner, far too late and also you deal with considerable production losses.
The first problem that is optimum is that the lining change happens when you planned it. This provides you the chance to have all of the needed parts on-hand before starting. This likewise permits you to execute other upkeep work on other tools when the adjustment is being carried out. Nowadays it’s hard to obtain screen media as well as manganese on a minute’s notification and also you will certainly require to prepare points if you need to lease a crane.
The second problem is transforming the lining before you start to suffer considerable production losses. Ahead adjust/screw readjust cones this is specifically real as the feed dimension begins to reduce quite considerably as soon as you get to the last 1/3 of life and as you near completion the feed size can get extremely tiny, shedding as much 30% of feed dimension. This is much less of a concern with hydro cones as the feed dimension remains consistent throughout the life of the manganese.
Substitute Procedure ：.
On the new crusher linings, place a mark on the adjustment cap driver ring where the pinion tooth makes contact with a driver ring tooth.
Maintain a record of the variety of teeth that made use of to compensate for lining wear on crusher linings.
Before relocating the dish, document the overall variety of teeth the chauffeur ring has actually relocated, and likewise repaint a horizontal lining on the side of the dust covering which the standard for determining just how close the next liner sets are to being worn out.
When a new liner set has actually been set up, maintain a record of the number of teeth the vehicle driver ring has actually relocated and also compared this number to the overall number from the preliminary collection of liners.
When transforming liners and also establishing lining wear, follow the guidelines in the associated crusher manual.
