What is the key to the spindle speed of Raymond mill?

There is a certain difference between the design speed and actual use speed of the Raymond mill. The rotation speed of the small Raymond mill is about 280-220 rpm, the rotation speed of the medium-sized Raymond mill is about 140-180 rpm, and the rotation speed of the large Raymond mill is about 60-120 rpm. The rotation speed of the Raymond mill is directly related to the output and performance of the Raymond mill. The grinding capacity indicators of the Raymond mill mainly have three items: the rotation speed of the central axis of the Raymond mill, the quality of the Raymond grinding roller, and the centrifugal radius of the Raymond grinding roller. The rotation speed of the central shaft is directly related to the use efficiency of the Raymond mill. The same Raymond mill may have different output due to the rotation speed of the central shaft of the Raymond mill. In the process of using the Raymond mill, some customers install their own inverters to easily control the spindle speed of the Raymond mill. Grinding light materials (or small materials) can reduce the speed of the Raymond mill because of this The grinding capacity of Raymond Mill is sufficient, and the reduction of speed is to save power consumption and noise of the machine. If it is heavy material (or massive hard material), it is necessary to increase the rotation speed of the central axis of the Raymond mill, thereby increasing the centrifugal force, increasing the grinding capacity, and increasing the output rate of the Raymond mill.

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...
