The Hd2150 Raymond Roller Grinding Mill from Guilin Hengda Ming Machinery Co., Ltd. is designed as one of Asia’s largest grinding machines, with a processing capacity of 60 t/h. This capacity exceeds R-type Raymond mills by approximately 30%, making it a preferred choice for large-scale non-metallic mineral powder processing. The machine achieves a production fineness of 80 to 400 mesh, suitable for industries requiring fine to ultra-fine powders.
The HD series incorporates a linkage pressure mechanism for the rollers, which extends equipment life and boosts capacity by 20% under the same power input. A patented variable frequency squirrel cage classifier ensures high-precision powder selection, with an efficiency of 99% and adjustable ranges between 80 and 600 mesh. The mill operates with low noise and vibration, even when grinding to 325-400 mesh, due to optimised airflow and grind space.
This mill is ideal for processing non-metallic, non-flammable, and non-explosive minerals with moisture content below 6% and Mohs hardness under 6. Common applications include limestone, marble, and dolomite for use in construction, chemical, and agricultural industries. The high-efficiency centrifugal blower, another patented feature, improves energy savings compared to traditional straight-blade fans. Buyers should confirm packaging, MOQ, and lead time directly with the supplier.

Prior to ordering, validate that the HD2150’s capacity and fineness range align with your production requirements, as its 60 t/h throughput and 80-400 mesh output are tailored for large-scale operations. Request a detailed technical specification sheet and, if possible, a sample test to ensure compatibility with your feedstock. Clarify whether the supplier offers customisation for specific applications or material types.
Logistics planning is critical for the HD2150, as its size and weight may require special handling. Discuss shipping terms, including Incoterms like FOB or CIF, and confirm the port of loading in China. Payment terms often involve a deposit followed by progress payments, so negotiate these upfront. Lead time can vary based on order volume and customisation, so insist on a written delivery schedule.
For quality assurance, inspect the mill’s classifier and blower assemblies upon delivery to ensure they meet patented design specifications. Request certificates of compliance for industry standards, if applicable, and confirm the warranty period for parts and labour. A pre-shipment inspection by a third party can help identify potential issues before the equipment arrives at your facility.
