Raymond mill automatic feeding device adjustment method

In the Raymond mill milling operation, there is a certain error due to the manual feed method, can not guarantee the uniform uniformity of the raymond mill feed, it is easy to cause the Raymond mill host mill cavity accumulation of material accumulation blockage or intermittent idling Case. The electromagnetic vibration feeding device, instead of manual Raymond mill automatic feeding way, can achieve continuous and uniform feeding, effectively avoiding the disadvantages of manual feeding, with low power, stable operation, easy maintenance and so on . Here, we focus on the Raymond mill automatic feeder adjustment method. When Raymond mill milling process, automatic feeding automation is achieved through the main motor and current to achieve. When the Raymond mill fan normal operation, if the host current exceeds the rated current will automatically stop the feed, the current dropped to the specified range will automatically feed. It can be said that this way of feeding is mainly through the current relay disconnect and connect the control voltage of silicon to achieve automatic feeding. In the Raymond mill milling operation, when the automatic feeding starts, turn the main switch of the control cabinet to the automatic position and gradually increase the potentiometer R1 knob on the control cabinet to reach the rated value range and keep stable status. At the same time, according to the rated current of the host to adjust the current relay sliding wall, change the relay operating current, the rise, the normally closed contact disconnected, the current will drop immediately closed, the Raymond mill always maintain the best working condition, Will not cause air grinding or overload, to ensure the efficiency of Raymond grinding flour. In addition, Raymond mill automatic dosing devices may also stop feeding in the event of a fan failure. DDL-12/6 overcurrent relay has two coils, when the series of its operating current can be adjusted from 1.5-3 amperes.

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...
