The working principle of  HD2500 Raymond Mill
 
1.Firstly,the crusher will crush the raw ore material .
2.The elevator will transport the crushed material to the feeding hopper .
3.The electronic magnetic vibration feeder feeds raw material into the main mill from the feeding port.
4. Driven by the actuator facility, the center shaft rotates the Plum Blossom Rack assembly , roller assembly and shovels together.
5.The rotating roller assembly installed on the Plum Blossom Rack high centrifugal to pull the roller close to the ring.
6. Meanwhile, the materials are shoveled into the gap between the ring and roller by the shovel blades.
7.Thus, the raw material will be grounded,extruded and stroke into fine powder by the rotary rollers and the ring .
8. After grounding , the blower will blow up the powder to the classifier and the classifier will separated the powder with the air.
9. Finally, the qualified fine powder pass from the classifier, then to be collected by the cyclone. Meanwhile, the unqualified products will fall back to the main mill for regrinding till be qualified.

 
With scientific & reasonable design and its unique advantages ,HD2500 Grinding Mill are applied widely in power, metallurgical, cement, chemical and non-metallic industry, for grinding of various materials, such as cement raw material, clinker, limestone, slag, manganese, gypsum, coal, barite, calcite etc.. The grinding field is wide and grinding type is abundant.
 
1. Humidity of grinding materials: from materials of less than 6 %(such as cement clinker), wide range of materials.
2. Grindability of materials: from high grindability(such as quartz sand, steel slag, mining slag, pyrophyllite, iron ore etc.) to low grindability (such as gypsum, calcite, etc).
3. Fineness of grinding product: from 2-5mm(such as raw shale for making brich in new wall material industry, sand for construction industry, etc) Product fineness is easy to adjust and simple operation.

 
HD2500 Grinding Mill consists of main mill, constraint turbine classifier, pipe system, high pressure blower, double cyclone collector system, pulse air collector, feeder, electronic control motor and jaw crusher, pan elevator. The main mill consists pedestal, return air box, shovel, roller, ring, housing and motor. The roller and ring are cast by wear-resistant material. Double gearing device and reducer device can be applied in the power unit of the whole system.

 
Technical Data
Note: The capacity is for  limestone powder , and specification is just a reference. The actual production depends on these materials being processed.
1. Large grinding power: HD2500 Grinding Mill uses four-roller pressurization to increase grinding power.
 
2. Large grinding area: Grinding height of grinding roller and grinding ring increased from 160mm to 200mm.
 
3. Large amount of shovel: use an enlarged blade to maximize the feed of material into the grinding roller and the grinding ring.
 
4. High classification accuracy: The use of ultra-large grading turbines has a high pass rate and a large air volume. Moreover, 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 accuracy is high.
 
5. Double cyclone collector: The parallel double cyclone collector is used, the collection efficiency is up to 80%, and the collection efficiency is increased by 10% compared with the single cyclone collector.
