How to reduce the energy consumption of jaw crusher

With the exploitation and utilization of mineral resources, non-ferrous metals, chemical industry, black metallurgy, light industry and other mineral resources are increasingly depleted, a substantial increase in mining, building materials, road construction and other industries required for the rapid increase in crushing materials, which makes gold ore crusher The role of growing. Jaw crusher is a very widely used crushing device. According to statistics, the national annual use in the crushing operation of the total power consumption in 2 × 109 or more, accounting for more than 50% of the total power consumption of the concentrator. So the design and production of energy efficient crusher is imperative. In order to reduce the energy consumption of jaw crusher crushed material, the structure of the jaw crusher needs to be improved and innovated to optimize its structure and trajectory. Specific measures such as improved crushing cavity type, now widely used in the deep crushing chamber and smaller bite angle, you can increase the crushing ratio of crusher and reduce the wear of crusher parts. Another example is to improve the moving jaw suspension and liner support, jaw plate with a new wear-resistant materials to reduce wear and tear. Another example is to improve the automation level of the crusher, such as overload protection, automatic adjustment, automatic lubrication and so on to achieve the level of automation. In addition, the researchers also developed a lot of new models. Such as the development of domestic experts to design a dual-chamber jaw crusher, is a typical four-link structure of the new gold ore crusher. There are two crusts with an eccentric axis centered symmetrically. Moving jaw left and right sides have a movable tooth plate, and fixed tooth plate were composed of left and right crushing chamber. At work, the material is broken in two crushing chambers in turn and is continuously circulated. So that the broken particle size is small, the motor can also be fully utilized, greatly enhance the production capacity. The above measures can reduce the jaw crusher energy consumption, and a substantial increase in the production capacity of crusher, to achieve the purpose of saving efficiency.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands
