In history, the jaw crusher and the oldest of the counter crusher. Impact crusher is characterized by small size, simple structure, broken than large (up to 40), less energy consumption, production capacity, product size uniformity, and selective role in the mine, is a very promising equipment TheThe state of the new type of counterattack crusher to change the traditional counter-break a single broken mode, the use of three-cavity and two-cavity broken like a combination of ways to greatly improve the application of counterattack crusher, making the counter-crusher can be convenient To achieve the material of the rough and fine broken processing, in the introduction of the market since the majority of gravel material production and processing customers wide acclaim, in the construction waste treatment, dry mortar production industry, widely used, the market prospect is broad.For more information about impact crusher,plz visit impact crusher for sale.continue reading
Shibang Heavy Industries: Mill ultrafine grinding technology beyond the self, walking in the forefront of the times
The same time as the above-
Mill grinding technology is accompanied by modern high-tech and new materials industry and the development of a new crushing engineering technology, has now become the most important industrial minerals and other raw materials, deep processing technology, the modern high-tech industry Development is of great significance.
Ultrafine grinding technology is an important part of powder engineering, including ultrafine grinding of powder raw materials, high precision grading and surface activity changes and so on. According to the size of raw materials and finished particles or particle size, crushing can be divided into coarse crushing, fine grinding, micro-comminution and ultra-fine grinding, which is a rough classification. It is noteworthy that the national industry due to the use of ultra-fine powder, preparation methods and technical difcontinue reading
1. mobile station: short length of broken tire mobile crushing equipment were installed in different independent mobile chassis, short wheelbase, small turning radius, flexible driving on ordinary roads and operation area.
2. the integration of complete sets of units: integrated equipment installation type, eliminating the separation components of the complex site, infrastructure installation operations, reducing material consumption and working hours. The reasonable and compact layout of the unit improves the flexibility of site stationing.
3. reduce material transportation costs: mobile crushing station can be processed materials at the site, and not necessarily move the material off the site, re processing, greatly reducing the transport costs of materials.

China is in the industrialization and urbanization to accelerate the development stage, the consumption of mineral resources, external dependence is higher. But the global mineral prices continue to rise, increasing the production costs of mineral products enterprises in the global supply of mineral resources, the situation, the mineral resources processing and utilization of the remaining residue, tailings, contains the second use of business opportunities. For a long time, due to the technical level and the level of knowledge is limited, management backward, extensive development and a series of reasons makes China's mineral resources tailings recovery rate is low, resource utilization is low. Which in addition to the target mine, other recyclable associated minerals and non-metallic minerals are mostly discharged into the tailings. Over time, the formation of the 'artificial deposits' or even 'artificial mineral groups', taking up a lot of land but also on the mineral resources causcontinue reading

Vertical mill roller body and a wear resistant lining plate in the use of the process, due to the friction between the roller and the pressure roller material force, material and grinding roller lining board; the material ground into the angle caused by the mutual comprehensive view the role of pressure stress force of the grinding roller shearing force, the hydraulic system pressure of roller mill and the mill table, these forces are acting on the vertical mill and effective compaction zone. Once appear, with the gap between the body and the liner will impact the collision occurred between the body and the liner wear intensifies, serious makes lining cracks and even rupture, causing liner off the machine damage, especially the damage caused by the malignant event reducer. Once this kind of problem occurs, the general repair method is difficult to solve. Disassembly, welding and machining are time-consuming and laborious, and the downtime and shutdown time are greatly prolonged, whichcontinue reading
The grinding roller is tightly pressed on the grinding ring under the influence of centrifugal force, so when the roller and the grinding ring are worn to a certain thickness, the yield and fineness of the finished product are not affected. The replacement cycle of grinding roll and grinding ring is long, so that the wearing parts of centrifugal crusher can be removed and the replacement cycle is short. The machine is in the airflow winnowing fan - mill shell - cyclone - fan internal circulating flow operation, so the ratio of high-speed centrifugal pulverizer and less dust, clean operation and no environmental pollution.Scope of application:Superfine mill is widely used in barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials with hardness less than 6.5, the high humidity in the 6% kinds of fine powder processing the following non inflammable and expcontinue reading
The crushing process is accomplished between fixed fixed cones and moving cones of cyclic motion.Cone crusher in the no-load running condition, the moving cone rotation is composed of spherical bearings for the friction torque and the eccentric shaft cone to cone friction numerical decision, which is the moving cone torque, according to the direction of rotation torque. Under normal conditions, the moving cone rotates along the rotation direction of the eccentric shaft, and the rotation speed is determined by the difference between the two torques. The cone crusher is between the spherical bearing and the movable cone to control the rotation of the moving cone. In the case of load operation, the friction moment of the stone to the moving cone cone is much higher than that of the eccentric sleeve against the moving cone.If you want to learn more about cone crusher,plz visit cone crusher for sale.continue reading
The modern crushing machinery was created successively after the gradual perfection and popularization of the power machines such as steam engines and motors.
In 1806, a roller crusher was driven by a steam engine;In 1858, Black of the United States invented the jaw crusher for crushing rocks;
In 1878, the United States developed gyratory crusher with continuous crushing action, and its production efficiency was higher than that of jaw crusher for intermittent crushing action;Domestic jaw crusher manufacturers are very different levels of technology, a small number of manufacturers of products close to the world's advanced level, and most manufacturers of products compared with the world's advanced level gap. Jaw crusher frame accounted for a large proportion of the quality of the machine (casting rack accounted for 50%, welding machine frame accounted for 30%). Jaw crusher abroad is welded frame, and even move jaw also adopts welding structure. It is the development direction that tcontinue reading
