Comparing the Application and Performance between the Ball Mill and Rod Mill

1. The performance of rod mill The rod mill is named by the steel bars which are loaded in the cylinder body as the grinding body. Ball Mill For Gold also adopts the wet overflow type. It is available as an open circuit ore grinding and widely used in the artificial sand, dressing plant, chemical plants and power sector. The grain characteristic of the rod mill product is related to the mineral condition. When the steel bars combating the ore, it becomes coarse ore firstly and then becomes the small sized ore grain which reduces the condition of over-pulverization. When the rods clamping the coarse grain turn upward along the liner, the fine grain will discharge from the space between the stick. It is also conducive to broken the coarse grain and make the coarse grain in the striking place. Therefore, the rod mill product is more uniform and the over smash is lighter. The selection of Rod Mill or rod mill in the process should depend on the specific circumstances. 2. The grinding process of rod mill and ball mill The function of the rod mill and grinding equipment are basically the same, but there are some differences between the grinding process and grinding application. Rod mill adopts the advanced controllable output materials technology and equips with suitable grinding body according to the grinding materials of the actual users. It changed the surface contact of the traditional ball mill into line contact which makes the feed size is more even and the output. It is suitable for different hardness of the ore. We can change the particle size with simple adjustment. The control device and the screening device can ensure the quality of the finished product. The most important equipment in the aerated concrete equipment is the ball mill. It is used for the grinding of lime, gypsum, slag and other materials. Materials only after grinding can meet the required fineness and then fully mixed to make the finished products meet the strength requirement. Vertical roller mill operation is the important progress in the production of aerated concrete. The power consumption in the grinding process is large. Generally speaking, the ball mill is the largest motor capacity equipment in the aerated concrete plant.

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
