Import 325mesh Marble And Tacl,Limestone Powder Grinder — Buy in wholesale FOB from Supplier in China

Shanghai Dingbo Machinery Co. manufactures a limestone powder grinder series capable of producing 325 mesh fineness, with models designated MTM100, MTM130, and MTM160. The machines use a trapezium grinding surface with roll-linked pressure boost, a departure from traditional Raymond mill architecture. The MTM100 carries four roller sets with a major roller diameter of 310 mm and width of 170 mm, revolving at 130 r/min, while the MTM160 scales to six rollers at 440 mm diameter and 270 mm width, turning at 82 r/min. Maximum feed size and throughput vary by model, with the range spanning 3-22 tonnes per hour. The 325 mesh capability means the mill can reduce limestone, marble, or talc to a median particle size near 44 microns, suitable for filler, coating, or chemical feedstock applications.

The grinding system is designed as an integrated production line from raw material feeding to powder collection and packaging. The drive train uses a confined gear box and pulley arrangement rather than direct motor coupling, intended to improve transmission stability. Key wear components are cast and machined from alloyed materials, though exact alloy specifications are not published. The electrical control system is centralised, with automated sequence control for start-up, operation, and shutdown. The trapezium mill geometry is claimed to improve classification efficiency, with a screening rate up to 99 per cent, though this figure should be verified against the buyer's specific feed characteristics and target fineness.

This equipment targets quarry operators, mineral processing plants, and construction material producers who need to comminute calcium carbonate or talc ore into fine powder for downstream industries. Applications extend to paper filler, plastic compounding, paint extender, and agricultural lime manufacturing. Buyers must confirm with Shanghai Dingbo Machinery Co. the exact motor power, dust collection configuration, and whether the quoted 3-22 t/h capacity applies to limestone, marble, or talc, as grindability varies significantly among these minerals. Spare parts availability, installation supervision, and commissioning support also require direct negotiation, as they are not detailed in the source material.

Shanghai Dingbo Machinery Co. is located at No. 17 Jinwen Road, Pudong Airport Industrial Park, Shanghai, in the 201323 postal area. The harbour trust tier indicates platform registration without supplementary accreditation. No response-rate statistics or average response time data is available, suggesting limited or untracked buyer communication history. The company profile does not disclose year of establishment, registered capital, number of employees, annual revenue, or installed machine base, so operational scale must be assessed through factory audit or direct disclosure.

The listing centres on trapezium mill equipment for limestone, marble, and talc comminution, with no evidence of unrelated product lines in the source material. The technical description emphasises in-house engineering and adoption of world-leading powder processing technology, though no patent numbers, R&D staff credentials, or collaboration partnerships are named. Buyers should request a company brochure, ISO 9001 or CE certification status, and reference installations with contactable end users to validate manufacturing capability and after-sales support infrastructure.
