raymond mill: working principle & parts | powder raymond mill - shanghai zenith company

In order to meet the requirements of different application areas, the development idea of "energy saving, high reliability, precision, automation" is an inevitable trend. Now, Raymond mills at current are beneficial for energy saving and environmental protection. They have high processing capacity, high separation efficiency and low energy consumption. Its expected that they will be more popular.

When the Raymond Mill is working, materials fed into the machine from the feed hopper on the side of machine shell. Relying on the grinding roller device, materials revolve around the vertical axis and rotate.

Raymond mill is widely used in the grinding of mineral products in metallurgy, building materials, chemical industry, mining and other fields. It is suitable for processing various non-flammable and explosive materials with Mohs hardness below 7 and humidity below 6%. Between 613m and 44m, the combination of the analyzer and the fan can meet the requirements of different users.

Silo: In order to improve the production efficiency, the preparation silo is arranged above the mixer, so that there is always a batch of the prepared materials waiting for mixing, which can increase the production efficiency by 30%, so as to reflect the advantages of the high-efficiency mixer. Secondly, the material will form a gas arch and it is difficult to cut the material. The silo should be equipped with a gas-assisted air cushion or a vibration motor. For maintenance and sealing, the silo port should be equipped with a pneumatic or manual valve. In order to smooth the material, the cone angle of the silo should not be greater than 60 degrees.

Feeder: The vibrating feeder uses the eccentric mass in the vibrator to generate centrifugal force, so that the moving part of the sieve box, vibrator and the like can be forced into a continuous circular or nearly circular motion. The material is continuously thrown with the screen box on the inclined screen surface, and the material is continuously and uniformly sent to the receiving port.

Raymond Mill is a common industrial milling equipment. Raymond Mills originated in 1906. CVGrueber created the Curt Von Grueber machinery factory in the southern suburbs of Berlin. So far, it has evolved for many generations. However, now Raymond Mill The performance of the powder machine is also much better than the Raymond grinding at that time;

Pulse dust collector: The pulse dust collector is when the dust-containing gas enters the dust collector from the air inlet, first hits the sloping plate and the baffle in the middle of the air inlet and outlet, the air flow turns into the ash hopper, and the air flow speed is slowed down due to inertia. The coarse particles of dust in the gas flow directly into the ash bucket. As a function of pre-collection, the airflow entering the ash bucket is then folded upwards and collected through the filter bag dust containing the metal skeleton inside, and is collected on the outer surface of the filter bag, and the purified gas enters the upper cleaning chamber of the filter bag chamber, and is collected. When the tuyere is discharged and the dust-containing gas is purified through the filter bag, the dust accumulated on the filter bag increases with time, increasing the resistance of the filter bag, causing the treatment air volume to gradually decrease, for normal work, to be controlled. Resistance is within a certain range

In main unit's working process, grinding roller device not only performs gyration by surrounding the central axisbut also performs revolution by surrounding the grinding ring. The grinding roller itself self- rotates by rubbing effect, the merit of which is that it can not only fully pulverize material, but also ensure uniform wear around grinding roller, increasing service life of grinding roller. perching knife, which is installed under grinding roller hanger, rotates with grinding roller at the same time. In this process, the perching knife throws up materials and feed them into grinding ring of grinding roller to form a padding layer. This padding layer is pulverized through outward centrifugal force generated by grinding rollernamely extrusion force between grinding roller and grinding ringfor the purpose of pulverization.

The existing material is introduced into the large silo by the existing sand cart, and the material is evenly fed into the Raymond mill by the automatic feeder, and the grinding powder and the grinding ring are ground by the mill, and the fine powder meets the fineness requirement. It enters the dust collector through the analysis machine, collects it in the dust collector, collects and stores it, and mentions it in the finished product warehouse through the hoist. The whole process belongs to the closed loop system and operates under negative pressure. It is equipped with a pulse dust collector to ensure the clean and tidy production site.

3. The system efficiency is low, the separation effect of the product collection system is not ideal, and a large amount of fine powder can not be effectively collected and repeated in the system to cause power waste.

4. There are mistakes in the design of the main air box air duct. The larger particles entering the material in the grinding area and the particles that have been mined in the future are often thrown into the bellows and gathered at the tail of the volute, and continue to extend forward, so that the amount of over-wind is gradually reduced. Causes traffic jams, no powder or less powder, affecting production.

According to accumulation and experimental analyses of on-site test data for more than thirty years, SBM, a Chinese grinding mill manufacturer, has researched and developed the fifth-generation pendulous hanging grinding mill MRN Grinding Mill. All non-combustible and non-explosive brittle mineral products whose Moh's hardness are below Grade 7 and water content below 6% could be ground by this grinding mill.

MTW European Grinding Mill is innovatively designed through deep research on grinding mills and development experience. It absorbs the latest European powder grinding technology and concept, and combines the suggestions of 9158 customers on grinding mills. This grinding mill perfectly satisfies the production demands of the customers on 200-33m (80-425Mesh) fine powder.

MTM Medium-speed Grinding Mill is a world leading tool for powder grinding. MTM grinding mill absorbs world first-class industrial powder milling technology and organizes the technical experts and related engineers for elaborate design, test and improvement.

raymond mills - raymond roller mill - grinding mill | agico cement

Raymond mill is also called Raymond roller mill. It is a new type of high-fineness grinding mill with high efficiency and closed circulation, which can completely replace the cement ball mill. This kind of machine is commonly used in cement plant for raw materials fine grinding, such as limestone, coal, gypsum, etc. Under normal conditions, these materials Mohs hardness should not be greater than 9.3 and the humidity should be under 6%. AGICO is one of the Raymond mill manufacturers in China. The Raymond roller mill we produced has the characteristic of stable performance, strong adaptability and high-cost performance. Its finished product fineness is usually between 0.61 and 0.033 mm, which can meet the requirements of different users.

When materials uniformly and continuously enter the machine body, they will be transported to the middle of the grinding roller and grinding ring by scraper blades,and during the grinding process, the materials will be stirred repeatedly by them. The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force so that the material is crushed into powder under the action of grinding pressure, and then entered into the analysis machine by the cycle wind of the blower. After that, the qualified materials will pass through the analysis machine and enter the classifier for separation and collection. Otherwise, they will be sent back to the grinding disc for further grinding.

AGICO Group is an integrative enterprise group. It is a Chinese company that specialized in manufacturing and exporting cement plants and cement equipment, providing the turnkey project from project design, equipment installation and equipment commissioning to equipment maintenance.
