Gypsum powder making machine Raymond Grinder Mill for gypsum board making

Same as other pulverizing equipment, HD1280 coal pulverizer has a simple working principle.

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 of the Gypsum powder making machine 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 separate 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 to be qualified.

Application of Gypsum powder making machine Raymond Grinder Mill for gypsum board making

With scientific & reasonable design and its unique advantages, HD1280  Metal Grinding mill is 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. The humidity of grinding materials: from materials of less than 6 %(such as cement clinker), a 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. The fineness of grinding product: from 2-5mm(such as raw shale for making brick in new wall material industry, sand for the construction industry, etc) Product fineness is easy to adjust and simple operation.

Structure of Gypsum powder making machine Raymond Grinder Mill for gypsum board making

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 Metal Grinding 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. A double gearing device and reducer device can be applied in the power unit of the whole system.

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 Gypsum powder making machine Raymond Grinder Mill for gypsum board making

HD1280  Raymond Grinder 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 a high output and low energy consumption.

1. High output. The output of this model is more than 50% higher than the output of the GYM9720  Raymond Grinder 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 Grinder 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.
