Through research and practice, design a kind of cyclone efficient damping rod device is additionally arranged on the superfine Raymond mill rotary wind dust collector, while maintaining the original dust collecting efficiency premise, reduce above 20% resistance, greatly reducing power consumption. At the same time in favor of multistage cyclone series, so that the dust collecting efficiency is improved to 95% to E. We also use the back-blowing cloth bag dust remover to charge 3% ~ 5% ultra-fine remaining powder, greatly improving the high number of days of powder dust capacity, to prevent the dust overflow, keeping the environment clean.

Air piping layout must be fast, and not the smooth transition, do not turn straight and curved, and the need to avoid pipeline arranged horizontally ; because the straight and curved will increase the big wind channel resistance, meanwhile bend straight and level pipeline easily deposited dust, will be made into a finished product contamination. But the original air supply pipe diameter is reduced by 1 / 5 and L / 4, to meet the needs of small flow, wind pressure ventilation requirements.

To obtain good classification effect, in addition to the classifier itself structure parameters should be reasonable, also depends on the volume and velocity of flow through the classifier. While the ordinary ray cast grinding blast volume is for the production of coarse powder index matching. The rated blast volume is very large, and leeway is lesser.

To obtain ultrafine powder is the main method of crushing and grinding open only from solid raw materials, supplemented by classifying technology so as to meet the various requirements of superfine powder. This is a high energy consumption industrial process, with all kinds of superfine powder and the increasing demand of the domestic and foreign related departments in the research of superfine grinding equipment, method and theory, in order to meet the industrial requirements.

Our understanding of Japan, United States, Germany and other manufacturers inspection, with the exception of a few also used vintage models in ordinary powder processing, apparent development on its principle and the improvement on the structure of the main configuration, ultrafine classification closed system, greatly expanded its scope of application, such as the common vertical roller mill, which can be directly the production of 1250 heads of the following ultra-fine powder, such as with more fine superfine grading equipment. Traditional Raymond mill product fineness in general 325 head to head between 400, we use the traditional Raymond mill the discovery in the process, Raymond Mill in processing calcite powder is 325 mesh, coarse powder containing a large amount of 10 um ultra-fine products, such as the separation of utilization and increase its production capacity, economic benefits is o values.

Henan Hongxing Mining Machinery Co., Ltd has many years' of technological power and experience accumulation of manufacturing and management of china jaw crusher, spiral concentrator which have many advantages such as simple and reasonable structure, high independent impact crushing ability, super low operational cost and the most competitive price. These machines have the most competitive price and the most reliable quality so that they are the top choice for the high performance crushing equipment. crusher machine: http://www.hxjq-crusher.com/2.html
