Ramond mill feed should be controlled properly

The feeding control of Upgraded version of Raymond Mill is very important, which is related to the grinding efficiency and particle size of the mill. The following to introduce the feeding machine control and automatic feeding method of setting. Ramond mill feeding machine adopts electromagnetic vibration feeding mode. The point vibration machine is a double particle directional forced vibration system. The armature is composed of a tank, an armature and a vibrating fork. The whole electric vibration feeder should be suspended in a free state, there should be a certain clearance around, there should be no collision between the material and the feeder, so as to avoid noise during work. After the installation, loosen the screws used for locating and connecting the fork check (three on the top and one on the bottom of the vibrator), and tighten the lock nut after loosening.
Open the vibrator back cover, check with armature iron core air gap within the scope of 1.8-2.1 ㎜, whether parallel and clean, and check all the screws have loose phenomenon, especially the armature iron core and plate spring clamping screws, all is well back cover on the back cover. Conduct no-load test with power on, adjust the potentiometer, gradually increase the amplitude from small, adjust the amplitude, observe the amplitude and current changes, the amplitude is 1.75 |-5%, the current is 0.6 -- 2.5a, continuously work for more than 1 hour to see whether the amplitude and current is stable, whether the screw in each part is loose now. Under normal circumstances, open the bin gate for material transfer, and observe again whether the amplitude and current are stable and whether the feeding quantity meets the requirements. If the amplitude and current are both in the rated value, if the feeding amount still does not meet the requirements, the vibrator can be hoisted into a downward inclined Angle, which can meet the requirements of the feeding amount, but the maximum inclination Angle is not more than 20 degrees.

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
