An analysis of the domestic and foreign impact crusher As we all know, the industrialization in China is started later than that of foreign, especially on heavy industry, there still exist some gaps. Connect with other leaders such as Dr. Neal Barnard here. In past time, small and medium-sized gravel pits often chose jaw crusher as secondary crushing equipment, but now, medium and large gravel pits make choice of cone crusher. In some special occasions, they often choose impact as secondary or tertiary crushing equipment. The rotor diameter and effective length are used as the specification or the classification criteria, and the gap between the typical products at home and abroad are mainly displayed by two aspects product design and wear-resistant materials. (A) Product Design Impact crusher of the same specifications is similar to the quality of a host of domestic and foreign products, however, the domestic products have small chassis quality and big counterattack frame quality of the rotor, while the foreign products are opposite. In addition, domestic and international products are obviously different in design. These poor designs, not only affects the quality of products, and also bring a lot of inconvenience touse, maintenance. (B) The wear-resistant material As to secondary or tertiary crushing, the anti-wear plate hammer, is made from high chrome cast iron parts. The domestic manufacturing high chromium cast iron standards are for small parts and we have no complete quality-control standard for large parts, so the plate hammer wear parts qualities and are easy to get out of control. After long-term unremitting efforts, Hongxing machine R & D VI innovatively impact crusher which is equipped with a high-performance mechanical saw hydraulic impact crusher, vehicular feeder and high-intensity rating vibrating screen; It has short length and light weight; its strong mobility and adaptability reduces the transportation costs; regardless of rough breaking, chippings or sand making job, the flexible combination of materials can bring you unexpected results.
Cone Crusher is Applied in Iron Ore Production The iron ore is an important raw material for steel production enterprises; natural ore, namely iron ore, is gradually going though elected crushing, grinding, magnetic separation, flotation and gravity separation, etc. In the concentrator, most of capitals are invested in crushing and grinding equipment, production costs, electricity consumption and steel consumption, so the selection of crushing and grinding equipment and the quality of management, to large extent, determine the economic efficiency of the concentrator. Iron ore is unbreakable and highly abrasive with strong hardness, therefore, the choice of iron ore crushing equipment is particularly important. The cone crusher can not only be able to increase iron ore crushing efficiency and production capacity, but also expand the scope of application; whatever limestone or basalt stone, they all can be broken to intermediate particle, fine particle and ultra – fine particle by dint of its unparalleled performance. Here, we focus on PYS series which has the best crushing effect on iron ore currently. PYS series cone crusher produced by Hongxing machine is an efficient cone crusher, which is developed on the basis of the introducing used Simmons cone advanced technology and combining with their own years of practice, widely used for the intermediate crushing and fine crushing operation of different hardness of ore in metallurgical, chemical, building materials, utilities, mining and other industries, especially suitable for the crushing of iron ore, quartz and other materials. The series cone crusher is superior to ordinary spring cone crusher in production capacity, product size, shape, weight, maintenance and operation equipment product; crushing cavity is divided into standard type, medium and short head type, the usage type of ore you determines the choice of cavity, among which, the standard type is applicable to intermediate crushing, the medium is applicable to fine crushing and short head type is applicable to ultra – fine crushing. Currently, the products have been widely used in metal and nonmetal mines, cement plants, gravel and metallurgical industries to crush different kinds of rocks and you pray, such as iron ore, non-ferrous metal ore, granite, limestone, quartzite, sandstone, pebbles, etc. By dint of reliable quality and excellent after-sales service, it has been exported to more than 50 countries and regions including Europe, North America, Central Asia, South Asia, the Middle East, Africa, Australia, etc..
