How to avoid the shaking phenomenon of jaw crusher?

Posted on February 2, 2012 by rzty

The workers applying jaw crusher know that after jaw crusher is used for some time, jaw crusher will have the shaking phenomenon. This action makes workers stop their work to check out shaking reason, so that they can repair the machine and restore production. In fact, as long as they pay more attention the machine at ordinary times, they can completely avoid this situation.

First, we should pay more attention screws fixing jaw crusher whether there is loose or rupture phenomenon. Jaw crusher needs to rely on the screws to be fixed on the ground. If the screw is coming loose or rupture, one side of the machine will happen firstly slight shaking. If we don’t tighten the loose screw or replace the screw of fracture in time, it will make the rest of the screw move easily or rupture, and then shaking phenomenon is more serious, even can damage the machine.

The second, we should check fixed foundation whether there is loose phenomenon. As is known to all, building houses needs to lay the good foundation. If the foundation is instable, it will collapse. Jaw crusher is the same, it needs to rely on the solid foundation, so that it won’t shake. If the foundations of the jaw crusher is unstable or happen loose in the process of long-term use, they both will affect the jaw crusher’s stability. So we must play a good foundation of jaw crusher, and check whether the foundation is loosen in the later use process once in a while. if so, we should timely reinforce.

The third, if the flywheel has deviation from the slot position in use process of jaw crusher, it will make the machine unbalance. So that the machine happen shaking phenomenon.

So the regular inspection and maintenance is very important in the use of jaw crusher.

Three points should bear in mind when choosing a crusher

Posted on January 16, 2012 by rzty

Jaw crusher, hammer crusher and other crushing equipments are mining equipments crushing materials. There are many mine crushing machinery manufacturers in domestic, and the quality of many equipment is uneven, some good and some bad. How to choose high quality crushing equipment? When choosing a crusher, buyers should pay attention to the following three points:

First of all, according to your raw materials need crushing. DSMAC crusher can process ore material. As with some pure metal, flammable and explosive, with high water content, high hardness, it can’t realize the crushing. For example, there is a large amount of steel in building waste material, which can’t be processed by stone crusher and need to dispose before the crushing. Another example, if the ore is with large amount of mud, the direct feeding can clog the crusher.

Secondly, you need to determine the fineness the products you want to precess the raw materials. Crushing machinery produced by dsmac include various kinds such as jaw crusher, hammer crusher, roll crusher and so on. Each crusher has its own body processing characteristic, such as the jaw crusher is used in the first crushing as well as the coarse crushing. In addition, the hardness is also one of the key factors should bear in mind when choosing a crusher, different material hardness determines different machines.

Finally, you should know the yield of the crushing machienry you demand, such as hammer crusher, the smallest PC400 * 300 devices, can reach 5-10 tonnes per hour, while PC800 * 600 equipment can achieve 15-30 tonnes per hour. The different types can meet different production requirements of various customers.

After understanding the above three points, you should refer to the big crushing machinery manufacturers with good reputation. Henan Hongji is a professional at manufacturing crushing equipment, which are all with the characteristics of big crushing ratio, uniform finished product size, simple structure, reliable work, convenient to repair, low operating costs and so on. Hongji is also the domestic and foreign well-known crusher producing enterprises.

How to lubricate impact crusher

Posted on January 5, 2012 by rzty

The impact crusher is dexterous and light, small size. Its structure is not very complex, so impact crusher is a new, effective mining equipment which has big reduction ratio. In practice, the impact crusher has a feature of less energy consumption and even granules, but plate hammer and counterattack plate are easily damaged, so we should pay attention to maintain lubrication work in the daily use .

(1) We should add the grease with right amount which is about 1/3-1/2 of mining machines space;
A large amount of grease can the increase friction torque, rise equipment temperature, so that machine wear is more serious. On the other hand, for few lubricating grease, it will happen friction inside the crusher without getting lubrication grease. As a rule, the suitable fatliquoring quantity of impact crusher is about 1/3 to 1/2 of mining machinery space’s total volume. Sometimes we should depending on the definite situation, we need to put some grease at the edge mine machinery and applied the cavity lubrication.

(2)We should insist on using the same brand of grease, and try to avoid use other brands;
we should try to use the same brand of lubrican in daily maintenance, and avoid using the mixing lubricating grease. If we don’t pay attention to this point, the probability of failure which the crusher appears will increase 13.2%.

(3)We should pay attention to hygiene issues in the process of filling grease;
Before we add the lubrication grease for equipment, we is first to close inspection containers and tools, it is better to use the dry dishcloth to wipe, then clean the mouth which can be put into the lubrication grease of the equipment, finally we should prevent dust, mechanical impurities and sand particles waste into the machine in the process of lubrication.

(4) We also note the seasonal differences;
If you are in the region, summer temperatures are very different from winter temperatures, the storage and choice of grease also should be seasonal. It is forbidden to use a kind of grease in winter and summer, or else lubrication effect it will backfire. It should also be noted that the grease should stored in a cool and dry place, and we don’t use the woodiness and paper material to pack and place grease.

Crusher making the building garbage change into building materials

Posted on December 28, 2011 by rzty

A large of construction waste can change into four different types of the sand through crushing and screening of two sets of crusher equipments in a few minutes. Then these materals fall from the machine and is called aggregate, they can be used to produce blocks, wall, floor tile and building materials products.

It is introduced that this project brings in the German advanced technology, high-tech content, which is the international advanced products. And this project just starts at home, also has the wide prospect of market.

According to estimates, with the development of urban construction, China’s annual produced only the construction waste and residue which the construction causes is at least more than 300 million tons in China, and makes up about 30% -40%of total rubbish. If we add other construction waste that architectural decoration, demolition, building materials industry produce, it will be larger number. Much more worrying is that the emissions are now also increasing year by year, the ratio of the increase is around 8% in the courty.

These buildings garbage don’t have professional processing field in most cities. They not only seriously pollute environment, but also take up much land.

The reuse comprehensive construction project of DSMAC renewable resources construction brings in Germany portable crusher. The waste and debris will be sorted and the waste also be broken in a specification size. At last they will be the regeneration of building materials which meet the requirements of environmental protection and quality, and they are widely applied in road construction, foundation base and so on. For the architecture garbage of waste wood, we also can produce raw materials of renewable plank or paper making through special process. The total investment of project is expected to 550 million yuan, the whole project is divided into three phase of construction.
