Analysis of several faults in Raymond mill

Raymond mill is a kind of milling machine imported from abroad. After the raw material of the ore is simply broken and crushed by the jaw crusher, it is transported to the storage bin by the bucket elevator, and then the material is transferred to the main grinding chamber of the Raymond mill through the electromagnetic vibration motor of the discharge port of the silo. The semi-finished fine powder is ground between the grinding roller and the grinding ring, and the fine powder is brought to the analysis machine by the fan airflow, and analyzed and screened by the analysis machine to meet the process requirements, and the air is brought to the large cyclone collector by the airflow. Auxiliary equipment for Raymond mill equipment. Here are a few common faults.
The parts are loose, and the parts that are newly processed and assembled have geometrical deviations. Because of the alternating load such as impact and vibration, as well as the influence of heat and deformation, and the wear and the like, the original fastening is easily made. The parts are loose. The deformation of the cylinder, the main reason for the deformation of the Raymond mill is that the mill causes the deformation of the cylinder under the combined action of the weight of the cylinder, the weight of the abrasive body and the weight of the material. When the machine is stopped for a long time, the tight body and part of the material are technically unloaded; the lubrication is poor, because the matching clearance of the newly assembled parts is small, it is difficult to ensure the average of the matching gap, and the lubricating oil is not easy to form an average on the friction surface. The oil film prevents the Raymond mill from wearing, which reduces the lubrication efficiency and causes abnormal wear in the early stage of the machine.

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...
