Due to the impact of COVID-19 on foreign exporting trade, the export contracts of Raymond mill for limestone signed by our company with foreign companies in India, Africa and South America have been extended until now.

With the gradual opening up of the international trade market, our company is carrying on the export and delivery of Raymond mill in an orderly manner.This model of raymond mill is for limestone grinding.

Following the shipment of HD-1620 Raymond mill to India last week, another HD-1620 Raymond mill for exporting to South America is being shipped to Shenzhen Port for overseas customers.

For a long time, Hangda Mining Machinery Co.,Ltd has laid a solid foundation for the cooperation between customers with excellent product quality and meticulous service.

At the same time we also accumulated a lot of export experience, and actively expand overseas markets, let the products to the world, won the praise and trust of overseas customers.

Advanced structure of the Grinding mill for limestone:

1.The main mill of the raymond mill adopts buffer device, and the structure of the housing barrel is optimized for stable operation and low noise.

The main mill and the analysis machine adopt the quick change pressing device, the maintenance is convenient.

2, large conveying capacity: the blower of the raymond mill adopts high pressure centrifugal fan, the air volume and air pressure increase, greatly improving the pneumatic conveying capacity.

3. High classification accuracy: the classifier of the raymond mill adopts squirrel cage cone turbine classifier, and the granularity of finished products can be adjusted arbitrarily within 80-400 mesh.

4, arc frictionless air duct: the air duct adopts arc frictionless air duct design to reduce the wind resistance, reduce the loss of air volume, so that the flow direction of materials is good, so as to increase the powder separation rate of the analysis machine.

5. New type of roller grinding device: the roller grinding device of the raymond mill adopts new type of maintenance-free structure with reliable sealing. Its bearings are lubricated with oil, thus reducing fuel consumption and maintenance cost.

6. Large amount of shoveling: super large shoveling knife is adopted to make the most amount of material sent into the grinding roller and grinding ring for grinding.The blade is made of alloy steel and durable.
