2、間相互作用很弱，破碎過程幾乎沒有選擇性。 近來國內(nèi)外開發(fā)的新型高效旋回破碎機破碎物料應(yīng)用的范圍不斷擴大，破碎產(chǎn)品粒度小，破碎效果顯著。目前旋回破碎機正向著大型、高效、可靠、節(jié)能、降耗和自動化方向發(fā)展。關(guān)鍵詞：礦山，破碎，旋回破碎機Abstract As society advances, the increasing consumption of raw materials, leading to the depletion of high-grade ore resources growing, increasingly depleted ore grade. China Metallurg

3、ical to mine, for example, the average grade of 31% of iron ore, manganese ore 22%. The vast majority of undressed ore broken grinding and milling needs to be dealt with after the furnace charge. Circular cone Breakers production efficiency, small size and homogeneous Pai expected to be broken mine

4、rock from 350mm to the different levels of particles lOmm, meet the skills needs of granularity,so Circular cone Breakers became the major equipment of Metal mines plants. 20th century the early 1950s, on the basis of the spring-loaded Breakers of former Soviet Union,developed its own domestic Break

5、ers.The most basic design concepts of this Breakers is control products granularity by the size of the mouth. Broken material way is by moving cone winding equipment and one-way squeeze role broken materials, weak interaction between materials, Broken process virtually no selectivity.And the recent

6、development of new highly efficient circular cone Breakers broken expanding the scope of application of materials, broken products granularity small, broken remarkable results. Currently circular cone Breakers is toward large, efficient, reliable, energy conservation, consumption and automation dire
