Product details
Product Features
The European version of the grinding machine, also known as the European version of the Raymond mill, is a new grinding equipment developed by authoritative experts from Shanghai Kolelic who have absorbed new grinding technologies and concepts from Europe, and have dedicated themselves to international technological level and multiple independent technological property rights. This model adopts multiple new technologies such as bevel gear integrated transmission, internal thin oil lubrication system, and curved air duct. Stable performance, easy operation, and low energy consumption; Adjustable and controllable particle size of finished products, widely used for grinding materials; Equipped with a dedicated dust collector, the dust emission concentration is completely lower than the national environmental protection regulations. The European version grinding machine is mainly suitable for grinding and processing mineral products such as metallurgy, building materials, chemicals, and mines. It can grind and process quartz, feldspar, calcite, talc, barite, fluorite, rare earths, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate ore, iron oxide red, zircon sand, slag, water slag, cement clinker, activated carbon, granite, garnet, iron oxide yellow, soybean cake, fertilizers, compound fertilizers, fly ash, bituminous coal, coking coal, lignite, diamond sand, chromium oxide green, gold ore, red mud, clay, kaolin, coke, coal gangue, porcelain clay, blue spar, fluorite, bentonite, diabase, pyrophyllite, shale, purple The Mohs hardness of sandstone, laminated rock, basalt, gypsum, graphite, silicon carbide, insulation materials, etc. is below level 9, Various non flammable and explosive mineral materials with humidity below 10%.
Performance advantages
-
Efficient and energy-saving
The coarse powder mill adopts the material layer grinding principle to grind materials, with low energy consumption. The power consumption of the grinding system is 20-30% lower than that of the ball mill, and the energy-saving effect is more significant with the increase of raw material moisture. -
Long service life of vulnerable parts
The use of special raw materials for vulnerable parts can generally last for more than one year, and when processing calcium carbonate and calcite, the service life can reach 2-5 years. -
High safety and reliability
Equipped with a limit mechanism to prevent direct contact between the roller sleeve and the grinding disc liner, it avoids destructive and violent vibrations caused by friction and collision between metals, increasing safety -
Environmental protection and cleanliness
The coarse powder mill adopts a fully sealed system, which operates under negative pressure, with no dust and a clean environment.

Working environment of European version grinding machine
1. Cleaning the equipment: After long-term operation, the grinding machine is prone to dirt that needs to be cleaned. During the cleaning process, high-pressure and high-temperature water guns should not be used to rinse, especially the electrical parts, which should not be washed with water to avoid electrical burnout.
2. Selection and replacement of oil: When selecting fuel oil, attention should be paid to the properties of the fuel oil. The commonly used fuel oil is diesel, but it should be noted that diesel with a freezing point higher than or equal to the ambient temperature should not be used. Generally, diesel with a temperature 5 degrees lower than the ambient temperature should be selected, such as -10 #, -20 #, -35 #, etc. When cleaning, it is also necessary to thoroughly clean the fuel system, and at the same time, check whether the fuel pump is normal to eliminate potential faults. Cleaning the fuel system is also to ensure that fuel oil can be added to keep up with the operation of the equipment during startup. For the replacement of lubricating oil or grease, attention should be paid to the equipment's use of lubricating oil, and whether replacement is necessary should be determined based on the amount used.
3. Maintenance of components: During the operation of the grinding machine, each component has different temperatures according to its work content. There is a cooling system in the equipment. During maintenance, attention should be paid not to allow sediment in the water tank of the cooling system. If it is found, it should be removed in a timely manner, and the water temperature in the water tank should not be too high or too low. Antifreeze should be added to the water tank.
Working principle
When the European version of the powder mill is in operation, large chunks of material are crushed to the required particle size by the jaw crusher, and then sent to the storage bin by the elevator. The material is then uniformly, quantitatively, and continuously fed into the main grinding room by the electromagnetic vibration feeder for grinding. The ground powder rises with the airflow of the fan and is classified by the powder selector. The powder that meets the fineness is separated and collected by the pipeline and discharged through the powder outlet valve to obtain the finished powder. The airflow is drawn into the centrifugal induced draft fan through the return duct at the upper end of the large cyclone powder collector. The entire airflow system of this machine is closed and circulates under positive and negative pressure. The working process of the European version grinding machine host is driven by a bevel gear integrated transmission device to rotate the central shaft. The upper end of the shaft is connected to the grinding roller hanger, which is equipped with a grinding roller device and forms a swinging fulcrum. The grinding roller device not only rotates around the central axis, but also revolves around the grinding ring, and the grinding roller itself rotates due to friction. A scraper is installed under the grinding roller hanger, located at the lower end of the grinding roller. During the rotation of the scraper and the grinding roller, the material is thrown up and fed between the grinding rings of the grinding roller, forming a cushion layer. This layer is crushed by the outward centrifugal force generated by the rotation of the grinding roller, thereby achieving the purpose of powder production. The European version powder selection machine uses a speed regulating motor to drive the blades on the turntable to rotate, forming a classification effect on the powder. The speed of the blades is adjusted according to the particle size of the finished powder. When obtaining finer grained powder, it is necessary to increase the blade speed to increase the contact between the blade and the powder, so that the powder that does not meet the requirements is thrown towards the outer wall by the blade and separated from the airflow. The coarse powder falls into the grinding chamber for regrinding due to its own gravity, and the qualified finished powder is sucked into the large cyclone powder collector through the blade along with the airflow. After the airflow and powder are separated, the powder is collected.
