Application of HD1280 Coal Pulverizer

With scientific & reasonable design and its unique advantages ,HD1280 Raymond 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.

Structure of HD1280 Raymond Mill 

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 of the Raymond Mill consists of pedestal, return air box, shovel, roller, grinding ring, housing and motor. The grinding roller and grinding ring are cast by wear-resistant material. Double gearing device and reducer device can be applied in the power unit of the whole system.

Data of HD1280 Raymond Mill 

Note: The capacity is for limestone powder, and specification is just a reference. The actual production of the pulverizing equipment depends on these materials being processed.

Advantages of HD1280 Coal Pulverizer

HD1280 Raymond Mill  is a kind of grinding machine between 4R and 5R mills. It is developed by our own engineers and technicians according to the development of the grinding 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 Mill.

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 mill structure . The main mill of the Raymond Mill  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.
