Operating status and working principle of ultrafine grinding machine

During the use of ultrafine grinding, there should be fixed personnel responsible for the inspection. The operator must have a certain level of technology. Before the installation of the grinding machine, technical personnel must be trained to understand the principle and performance of the milling machine. . During the use of ultrafine mill equipment, there should be fixed personnel responsible for the inspection. The operators must have a certain level of technology. Before the installation of the grinding machine, technical personnel must be trained to understand the principle and performance of the milling machine. Operating procedures. Only the process that is familiar with the operation can make the grinding machine equipment be applied to the production process well, and at the same time, the machine efficiency is also greatly improved. This is also the reason, and daily maintenance and maintenance should be done.

The equipment is widely used in barite, calcite, potassium feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials. High-fine powder processing of more than 300 materials such as non-flammable and explosive minerals, chemicals, construction and other industries with a Mohs hardness of not more than 7 grades and a humidity of 6% or less. The R-type superfine mill has a finished grain size of 80- Any adjustment within the range of 325 mesh, some materials up to 600 mesh.

The structure of the machine is mainly composed of a main machine, an analysis machine, a blower, a finished cyclone, a pipeline device, a motor and the like. The main machine is composed of a frame, an inlet volute, a blade, a grinding roller, a grinding ring, a casing and a motor. Auxiliary equipment includes jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc. Users can flexibly choose according to the site conditions.


After the ultrafine grinding work, the large-sized raw materials are crushed to the required feed particle size, and the material is transported to the storage bin by the bucket elevator, and then the electromagnetic vibrating feeder is evenly sent to the grinding chamber of the main machine to enter The material into the grinding chamber is shoveled by the blade into the grinding roller and the grinding ring is crushed, the blower blows air from the diverter disc into the grinding chamber, and the pulverized powder is sent to the analysis chamber, and is driven by the speed regulating motor through the transmission device. Rotating analysis of the impeller is sorted, the large granular material falls back to the grinding chamber, regrind, and the qualified fine powder enters the finished cyclone collector with the airflow, and after being separated from the air, it is discharged from the discharge port into a finished product. The blade system plays a very important role in the operation of the main engine. The utility model is located at the lower end of the grinding roller, and the material is shoveled and fed into the roller ring between the blade and the grinding roller to form a cushion layer, and the material layer is rotated by the grinding roller to generate an outward pressing force to the material. Milling, thereby achieving the purpose of milling.

The price and application range of limestone superfine mill

The mineral limestone is processed by the mill to produce limestone powder of different fineness, which plays an important role in the industry. The use of limestone powder with different fineness is widely used. Some customers come to consult the processing of limestone powder. I believe everyone knows that today’s lime and limestone have been used in construction materials and industrial raw materials. Limestone is directly processed into stone and fired into quicklime. The quicklime absorbs moisture or adds water to become slaked lime. The main component is Ca(OH)2. The slaked lime is formulated into a lime slurry, a lime paste, etc., and is used as a coating material and a tile adhesive.

According to the application, limestone powder can be divided into limestone powder for building materials, limestone powder for chemical industry, limestone powder for mold, limestone powder for food and limestone powder for casting, etc. The raw material of limestone powder is deep-processed and ground by lime mill ore. The limestone powdering equipment produced by Veken Shanghai Keli includes: Raymond mill, high-pressure medium-speed mill, European mill, ultrafine mill, three-ring mill, etc. The finished product of the Mongolian mill and the high-pressure medium-speed mill has a particle size of 80-425 mesh, and the ultrafine mill and the three-ring medium-speed mill have a fineness of 300-3000 mesh.

The Raymond mill is commonly used to process 200 mesh limestone. The limestone is first conveyed to the jaw crusher through the vibrating screen for coarse crushing, and then enters into the mill for grinding. When the main motor power is decelerated by the gear reducer, it is driven. When the central shaft and the plum blossom frame fixed on the central shaft rotate, the grinding roller rotates around the central axis under the action of centrifugal force, and also swings parallel to the support shaft, so that the grinding roller presses the grinding ring outward in parallel, thereby ensuring the grinding roller and The grinding ring is in contact with the large face. At the same time, the grinding roller rotates around the grinding roller shaft, so that the material shoveled by the blade reaches the pulverizing and grinding action therebetween, and the pulverized powder is blown by the airflow of the air blower to the analysis machine above the main machine for screening, and the coarse particle size still falls. Re-grinding in the main chamber, the particle size meets the requirements of the windflow into the large cyclone collector, and after collection, it is discharged through the powder discharge tube.

Limestone ultrafine grinding machine is a simple operation grinding equipment. It has comprehensive mechanical crushing performance such as rolling and milling. It can produce 200-3000 mesh powder, with small floor space, low energy consumption, maintenance, and cost performance. A high machine is a scientific ideal grinding machine. What is the price of such a skill-friendly ultrafine grinding machine? Collieric is scientifically formulated according to the grinding requirements of a large number of customers, such as fineness, production capacity, production area, and finished product application fields. It is an important basis for formulating science and science.
