Generally speaking, after crushing and grinding, this special stone will reach the requirement for cement raw material. With the speeding up of opening up to the world and national economic construction, the development of the cement industry has been very fast. During the twelfth five years plan period, with the speeding up of the transformation of the economic development methods, the demand for the cement in the domestic market will increase in a stable and current speed instead of at a very fast speed, the development of the cement base material and the cement manufacturing products will be very fast. It is predicted that the average annual increase will be three percent to four percent and the domestic cement need in 2015 will be about 2200 million to 2300 million, for this reason, the demand for limestone in the cement manufacturing industry will increase significantly.
In recent days, more than half cities of our country fall into serious haze which is a warning to the environmental pollution. Experts explain that in the all reasons led to haze weather, smoke contamination and flawing dust pollution in industries occupies a large proportion.
Therefore, it caused a stir in sand making, ore beneficiation and crushing machine industries. People in these industries raised that we should make efforts to the pollution abatement and weed out crushing equipment with high consumption, high dust and high pollution gradually. Then, environmentally friendly crushing equipments become the focus of the whole industry. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like Ball mill, Henan Hongxing is always doing the best in products and service.stone breaking machine: http://www.crusher-machine.com/n217.html
The so-called environmentally friendly crushing equipments mean equipments adopted modern crushing technics and equipped with high-efficiency dedusting device. In this way, these equipments can reduce the dust spillover to the maximum degree so as to achieve the goal of zero waste of ore materials and the promotion of production capacity.
With the limestone crusher as an example, limestone, as the important resource of architectural materials industry and the main raw materials of making cement, lime production and calcium carbide, can be produced as limestone sand aggregate and aerated concrete block. Nevertheless, according to survey, many limestone crushing equipments in the market are only the combination of some spare parts which have low technology and lead to the serious resource waste and dust pollution.
Hence, Henan Hongxing Machinery has oriented environmental protection as the key factor during research and development. The limestone crusher and large impact crusher have the advantages of low electricity consumption, low noise and little dust pollution which are the real high-efficiency crushing equipments.
