General Directorate

From that entered Pere Navarro to the General Directorate of traffic as director-general, were led to believe through all available means that fines, radars and the carnet by points are for our safety. 4 Years we have been suffering from harassment, from newspapers up bulletin boards lights of highways us have gotten into the head for your safety. In addition each time more and more, the news of newspapers announcing that they plan to achieve so much money with the fines appeared every day. Because we are in summer of 2010, with all the cuts in salaries to officials and look that grace, the civil guards have said!Stop it! And have kept the their pens in their pockets doing a silent strike, the strike of the bolis fallen, those that do much harm. They, those who charge less than any national or Municipal, police did irreparable damage not only in the coffers public if not in the phrase for your safety. The fines have left a fundraising 40% less, but look how strange that not increase in accidents, not only that. He fell!! So as things stand, perhaps all this fines does not help as much as I thought, perhaps the important thing is to educate people about as must each behave in the car. That at age 18, when the meat is given, already we can think for ourselves. And in Switzerland, the fines should be proportionate with the salary. A good thing that made the DGT has been modernized a bit and now allows us the payment of fines by internet.

Effective Measures

Compound crusher is widely used in the fine crushing of limestone, clinker, coal and other minerals in building mining, metallurgical and chemical industries, and also used in the fine crushing of dolomite and the chamotte, gold, serpentine, high slag, gangue and phosphate rock, these med-hardness materials. combination crusher is suitable for sand making of hard limestone, dolomite, granite, basalt, and highway stone crushing. The compression strength is less than 140 Mpa. The humidity is not more than 15%.The combination crusher is one of the most common fashion in crushing and sand making production line, while its engine is usually damaged; Hongxing machine experts holds view that there are many reasons lead to the damage of combination crusher motor; Besides conventional failure cause of motor common power equipment, the running fault of combination crusher also can damage the engine, shown as follows:1. The reliability and sensitivity of the automatic pressure switch; the starts and stops of compound crusher are normally controlled by the automatic pressure switch (pressure relay) directamente driving alternating current contactor. The automatic pressure switch mostly adopts mechanical structure, which act on contact by the compress and release of spring. The congenital deficiencies or improper adjustment of automatic pressure switch can cause engine damage.2. The electrical control (especially for low-power type) is relatively simple, they are generally work independently by stand – alone group and lying in a professional operation occasions with torpid repair and maintance, which relatively increase in repeat expansion rate of failure.Due to the combination crusher works in harsh conditions in long term, the wear of rotor bearing is exacerbated.

The rotor is irreplaceable for crusher so that crusher cannot work without it. However, it is also fragile; the bearing rotor is not only expensive, but also replaced difficultly, often resulting in the cut-off loss.How to take effective measures to improve the rotor bearing life is an important matter that our customers concern about, asking us pay more attention:First, make correct choice of rotor-bearing model. Double row radial spherical roller bearing with strong bearing capacity and aligning performance, it is worthy being chosen. In addition, the rotor which is with design life of 5000 10000h is appropriate.Second, improve the status of crusher bearing force. The impact load working on the bearing depends on the impulse acting on the rotor and the flexibility of bearing support. Increasing bearing support flexibility will reduce the impact load on the bearings working. To this end, we could add rubber sheet with appropriate thickness between the bearing and the support frame to improve the bearing support flexibility and to achieve the purpose of extending the service life.They are widely used for crushing various materials like stone, granite, trap rock, coke, coal, manganese ore, iron ore, emery, fused aluminum, oxide, fused calcium carbide, lime stone, quartzite, alloys, etc.
