The working principle of the new vertical mill

The new Vertical Roller Mill can transport the large raw materials to the required feed size, and then transport the materials to the storage bin by the bucket elevator, and then send them to the grinding chamber of the main machine through the electromagnetic feeder. The material in the grinding chamber is ground between the grinding roller and the grinding ring, and the powder after the powder is taken by the fan airflow to the analyzer to classify, and the fine powder reaching the fineness standard is sent into the large cyclone collector through the airflow. The product is collected separately and discharged through the unloader. The main machine operation process is carried out by means of a branching device to drive the central axis to roll. The upper end of the shaft is connected with the plum blossom frame, and the frame is equipped with a grinding roller to form a swing fulcrum, which not only surrounds the center, but also rotates the roller around the grinding ring. During the same process of the blade and the grinding roller, the material shovel is fed between the grinding roller and the grinding ring to form a cushion layer, and the material layer is crushed by the grinding roller to generate an outward centrifugal force (ie, pressing force) to crush the material. , thus reaching the milling intention. The profiler rotates through the speed-regulating motor and drives the blades on the turntable through the secondary deceleration to form a classification effect on the powder. The speed of the blade rotation speed is adjusted according to the particle size of the product. When it is necessary to obtain finer particles, it is necessary to improve the rotation speed of the blade, so that the touch of the leaf and the powder is increased, so that the undesired powder is thrown away from the airflow by the blade, and the coarse particles fall into the grinding due to the effect of gravity. The chamber is reground, and the qualified powder is sucked into the large cyclone collector through the airflow. After the airflow and the powder are separated, the powder is collected. The large cyclone collector plays an important role in the performance of the mill. The effect is that when the powder airflow enters the collector, it is a high-speed rotation condition. After the airflow and the powder are separated, the airflow and the powder are separated, and the airflow moves to the cone bottom when the cone wall shrinks toward the center (from the natural length of the airflow). A rotating airflow cylinder, at which point the powder is collected.

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...
