Introduction of Raymond Mill For Sale 325 Mesh
Raymond mill widely used in grinding equipment of mine, cement, chemical industry, is one of the important equipment of non metallic mineral deep procession. Since its strong stability,adaptability and high cost performance it has popularized in non metallic mineral processing field. Applied in grinding various non plastic ore, mineral soil,metallic oxide, chemical composition etc. which Mohs hardness not more than grade 7,humidity less than 6% non flammable and combustible material such as speckstone, dinas rock, graphite, fluorite, magnesia stone, bentonite, kaoline, pottery clay etc.
Features of Raymond Mill For Sale 325 Mesh
1. High capacity, 1-20t/h.
2.The fineness can be adjusted between 50 and 325 mesh (315-45 micron).
3. Fixed with 1000-1500kg pressure springs, and its capacity increase 20% to 30%; When the grinding roller and grinding ring, stable capacity and fineness can be guaranteed.
4. Easy maintenance, simple structure, low investment
5. Environment-friendly. Application of pulse bag filter & muffler greatly alleviates dust pollution and noise.
6. Advanced intelligent speed control device. Convenient adjusting, uniform particle size.
The machine has the following characteristics:
1. The reducer adopts a new type of deceleration device: the main engine speed can be adjusted according to different working conditions, and the main engine speed can be adjusted to adapt to different hardness materials.
2. Large amount of shovel: use an enlarged blade to maximize the feed of material into the grinding roller and the ginding ring.
3. The mainframe structure is advanced: the main machine adopts the buffer device, the main cover tube structure is optimized, the operation is stable and the noise is low; the main machine and the analysis machine adopt the quick change pressing device, and the maintenance is convenient. The base of the main unit is raised, the grinding roller and the grinding ring are raised to 280 mm, which increases the grinding area.
4. High classification precision: The use of ultra-large grading turbines has a high pass rate and a large air volume. And the end surface of the classifying impeller sealing blade and the sealing end surface of the powder discharging port form a palace seal, and it is not easy to form a short circuit powder, and the classification precision is high.
5. Double cyclone collector: Parallel double cyclone collector, collection efficiency of up to 80%,10% higher collection ffciency than single cyclone ollector.
6. Curved non-resistance air duct: The air duct adopts a curved non-resistance air duct design to reduce wind resistance, reduce air volume loss, and make material flow direction good, thereby increasing the analyzer's powder selection rate.
7. New grinding roller device: The grinding roller device adopts a new maintenance-free structure, and the sealing is reliable. The bearings are lubricated with oil, low fuel consumption and low maintenance cost.
8. Large conveying capacity: the air blower adopts a high-pressure centrifugal fan, and the air volume and air pressure increase, which greatly improves the pneumatic conveying capacity.
9. The wind is collected in a cloth bag, no dust pollution.
Working Principle of Raymond Mill For Sale 325 Mesh
Big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The bevel gear drives the central shaft to the rotate ,the shaft top is connected with a grinding roller hanger,on which a grinding roller device is mounted to form a swinging pivot. The grinding roller device rotates around not only the central shaft but also along the grinding ring,with the grinding roller rotating itself under the action of the friction. The grinding roller hanger has a shovel blade installed at the bottom of roller, the shovel blade and grinding roller throw up and feed the material between the grinding rollers and ring during mutual rotation to form a bedding layer ,which will produce an outward centrifugal force ( an extrusion force ) by the rotation of grinding roller to crush the materials.The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there. They are discharged at the discharging valve to become finished products; the airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
