The working principle of HD1280  Coal Pulverizer
 
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 ,HD1280 Coal Pulverizer 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.

 
HD1280 Coal Pulverizes 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 Date

Note: The capacity is for limestone powder, and specification is just a reference. The actual production depends on these materials being processed.
Performance Advantage
HD-1280 improved mill is a kind of machine between 4R and 5R mills. It is developed by our engineers and technicians according to the development of the market. This model has high output and low energy consumption.
 
 
1). High output. The output of this model is more than 50% higher than the output of GYM9720 Raymond machine.
 
2）. Large conveying capacity.The air blower adopts a high-pressure centrifugal fan. By doing this, the air volume and air pressure increased to greatly improve the pneumatic conveying capacity.
 
3）. High classification precision.The classifier adopts the built-in squirrel cage cone turbine classifier. As a result, the finished product granularity can be adjusted arbitrarily within 80-500 mesh.
 
4）.Advanced main engine structure . The main engine adopts the buffer device. The main engine cover structure is optimized design, the operation is stable and the noise is low; the main engine and the classify machine adopt the quick change pressing device, which is convenient for maintenance.
 
5）. 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.
