Application of HD9720 Raymond Mill

With scientific & reasonable design and its unique advantages ,HD9720 Raymond Mills 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 HD9720 Raymond Mill

HD9720 Raymond Mills 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。

Data of HD9720 Raymond Mill

Note: The capacity is for limestone powder Raymond Mill, and specification is just a reference. The actual production depends on these materials being processed.

Performace advantages of HD9720 Raymond Mill

1）.The reducer of HD9720 Raymond mill 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 grinding ring.

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.

3）. 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.

4）. Double cyclone collector: Parallel double cyclone collector, collection efficiency of up to 80%, 10% higher collection efficiency than single cyclone collector.
