The machinery industry has always been highly valued by the government and has become one of the important factors in leading the market economy. The mining machinery and equipment closely related to the machinery industry have attracted the attention of all the people. According to statistics, after entering 2014, the production of mining machinery and equipment has grown rapidly compared with the same period of last year, and its growth rate is about 30% to 45%. The increase in the production of mining machinery and equipment has also led to the development of the entire national economy, especially the overall progress of the machinery industry. Today, the domestic machinery industry has developed rapidly. Compared with developed countries, the gap has gradually narrowed, and even some large mines Mechanical users have started to be in line with international standards. In this development situation, the market demand for the mining machinery industry has also changed.
According to relevant experts' forecast, the market demand for the mining machinery industry in 2015 will be based on sustainable development of green environmental protection equipment and technology. Based on the principles of energy reuse and low consumption and low cost, the company will choose pollution-free and energy-saving in actual production. Safe technical equipment. As a result, environmental protection tailings dryer equipment has entered people's field of vision, and has gradually become the top priority of the mining machinery industry.
Most companies claim that they have benefited greatly from the use of tailings drying technology. Most of them are proud to say that the tailings drying technology not only helped them solve the difficult problems of tailings disposal and the treatment of goafs. To a certain extent, it also reduces the safety risks for them. It will not impose a burden on the environment while increasing the economic efficiency of the company.
Tailings are useless wastes that are emitted after the completion of mining ore dressing. These wastes are accumulated on a monthly basis to form a tailings pond. Tailings ponds have caused great harm to the environment and there are still great potential safety hazards. Therefore, they have always been valued by various countries. Eco-friendly tailings dryers came into being. They dewatered the tailings, and the separated water resources achieved the effect of recycling. The tailings dry heaps were also used in fields such as field production and in accordance with the requirements. The concept of “environmental protection†advocated by the country has also responded to the new trend of internationalization in 2015. Under this new international trend, Gongyi City Jinhua Machinery Factory first adopted and promoted tailings drying technology, successfully achieved the goal of small investment, low consumption, and low cost, ahead of other domestic mining machinery companies. One of the first domestic representative companies for tailings drying technology.
China is a big country in the mining machinery industry, but it is not a strong country in the industry in the world. With the development of the Chinese economy, the competition in the mining machinery industry will inevitably become more intense. In 2015, China will also respond to new changes in international demand, introduce more environmentally friendly and sustainable technologies and equipment, and increase the promotion of environmentally friendly tailings dryers. Enterprises want to survive in such a large environment, they should adapt to the needs of the new international market faster, change the direction of production, and introduce more new green technologies such as tailings drying.
According to the filtration principle, the air filter can be divided into filter type, centrifugal type, oil bath type, several compound type. The air filters commonly used in the engine are mainly inertial oil bath air filter, paper dry air filter, polyurethane filter element air filter and so on. Inertial oil bath type air filter has been through the inertia type filter, oil bath type filter, filter type filter three filter, the last two kinds of air filter is mainly through the filter element filter. Inertia oil bath type air filter has the advantages of small air intake resistance, can adapt to the dust and sand working environment, long service life, etc., used in a variety of models of automobile, tractor engine. But this kind of air filter has low filtration efficiency, heavy weight, high cost and inconvenient maintenance, so it has been gradually phased out in automobile engines. The filter element of paper dry air filter is made of microporous filter paper treated with resin. The filter paper is porous, loose and folded, with a certain mechanical strength and water resistance. It has the advantages of high filtration efficiency, simple structure, light weight, low cost and convenient maintenance. The filter element of the air filter is made of soft, porous and spongy polyurethane, with strong adsorption capacity. This air filter has the advantages of paper dry air filter, but its mechanical strength is low, and it is widely used in car engines. The disadvantages of the latter two air filters are short service life and unreliable work in harsh environmental conditions.
