Abrasion and maintenance of commonly used crushers in ore dressing

Environment of ore beneficiation is complex and bad. At work, crushing machines in ore beneficiation line often break down. The reasons causing equipment failures are various, including unreasonable design of ore dressing equipment, improper management and maintenance in operation process and so on. The slag crusher in ore dressing line are mainly used to crush and process ores with high hardness, which have big workload and long working time. Hence, wearing problem of these crushing machines is very serious, which is also the reason leading to short lifespan of equipment. Crushing is the link which is most seriously worn in ore dressing process. While coarse crushers are the machines directly contacting with ores, which are mainly responsible for crushing raw ores into suitable sizes that fits for medium and fine crushers. Therefore, abrasion of coarse crushers is the most serious. Here, the experts of our company simply talk about abrasion and maintenance methods of commonly used crushers in ore dressing line.

1. Abrasion of coarse crushers

Commonly used coarse crushers are mainly jaw crusher and gyratory crusher.The seriously wearing part of jaw rock aw crusher is toothed plate. Because in periodical working process, toothed plate of jaw crusher is loaded or unloaded periodically. Hence, the material strength of toothed plate should be very high. Meanwhile, the toothed plate is often deformed or worn due to long-term immersion of high hardness ores., and then being fractured. Under normal conditions, toothed plate is fixed on cast steel by high manganese steel plate. After having used for a period of time, the high manganese steel plate should be turned around for reusing or directly replace new high manganese steel plate. Wearing part of coal processing plant is lining board. Because in using process of crushers, impact of the lining board is the biggest, so its abrasion is the most seriously. Therefore, materials of the lining board of gyratory crusher should be equipped with high strength and wear resistance.

2. Maintenance methods of coarse crusher

In general, quality is the precondition of highly efficient operation and production of equipment. scientific and reasonable maintenance is fundamental guarantee of long-term operation of equipment. So, purchase and daily maintenance of coarse crushing equipment are fundamental starting points of long-tem running of equipment. Firstly, selection of coarse crushers should accord with ore types and form of mines. It’s well known that the same work can select different machines to complete, but the effect is not necessarily the same. Hence, when choosing coarse crushing equipment, we should be cautious and combine with actual situation so as to ensure that the selected equipment satisfy characteristics of minerals to the greatest extent. Even the same minerals, we should also carry out the specificity monitoring so as to select optimal equipment.

Secondly, we should also use the equipment with new technology and materials as far as possible, which can’t rely on old high manganese steel materials. We can select equipment with high degree of automation. Thirdly, we should regularly check important parts of equipment so that we can find and solve problems in a timely manner. When it’s necessary, we can stop production to carry out inspection so as to avoid unnecessary lose. Lastly, wear resistance of materials of equipment should be high, thus we can discover frequent troubles and other wastage beyond normal range when the equipment is in normal maintenance stage.

Application of new materials in crushing equipment

With the development of science and technology, the coal crushing plant not only makes great improvement in the technology, but makes breakthroughs in the application of equipment materials.This material has many advantages such as low proportion, strong performance of resistance to corrosion, abrasion and friction and explosion and sufficient mechanical strength so that it is able to match the metal materials. For this reason, in recent years the plastic materials has bigger proportion in the spare parts of the mechanical products and many countries have laid down plastic standard for the industrial departs to use.

The movable jaw bearing of the simple-pendulum jaw crusher adopts oiliness synthetic resin. Using the plastic to produce the spare parts of the machines will not only save the metal and lower the weight, but improve the performance of the aggregate processing plant, enhance the reliability, extend the service life and reduce the production cost of the machine.

After many years of experiments and research, it proves that the abrasion of smooth manganese steel lining board is two-fold faster than that normal rubber lining board. The abrasion of the rubber lining board with muscle only occurs on the top of the muscles, and the part between the muscles is not abraded. As for the smooth rubber lining board and the rubber lining board with muscles, the abrasion amount of the rubber in the unit time is the same. For this reason, the consumption amount of the rubber lining board with muscles by every ton of materials is only one third of the smooth lining board. The abrasion of the rubber varies along with the size and the speed of the machine and the hardness of the materials.

When replacing the steel lining board with the rubber lining board, the wood or steel materials cannot be used for filling the gap. Since the rubber plate is inflammable, the installation work of the lining plate should be done in a fire-proof condition. What should paid attention be to be that the grinding capacity of the grinding mill using the rubber lining board is not undermined, but increased by 10-15%. This is because 5% of the power of the grinding mill using steel lining board is consumed by the carcass, but as for the grinding mill using the rubber lining board, all of the power is used in the crushing due to the bouncing effect of the rubber.
