Import Best Selling Natural Rubber Crusher — Buy in wholesale FOB from Supplier in China

The YB-250X500 and YB-450X650 are double roller crushers purpose-built for flattening and processing natural rubber in industrial settings. These machines employ two counter-rotating rollers to compress and shear rubber sheets or bales into thinner, uniform layers ready for downstream manufacturing. The YB-250X500 designation indicates a 250mm by 500mm working roller dimension, while the YB-450X650 scales to 450mm by 650mm for higher throughput requirements. Both models feature adjustable roller gap settings to accommodate varying rubber hardness and thickness inputs. The frame construction is welded steel with roller surfaces typically hardened to resist abrasion from raw rubber contact. Drive systems are powered by electric motors with gearbox reduction, though exact kW ratings require supplier confirmation. Standard feed methods include manual loading of rubber slabs or conveyor-fed continuous operation, depending on plant layout.

Natural rubber processing demands specific material handling due to the polymer's tackiness and elasticity at ambient temperatures. The crusher rollers are typically manufactured from chilled cast iron or alloy steel with surface hardness in the range of 65-72 HRC, a standard for rubber processing equipment. Roller journals run in self-aligning spherical roller bearings to maintain parallel gap settings under load. The YB series employs mechanical or hydraulic gap adjustment, with typical adjustment ranges of 0.5mm to 20mm depending on roller diameter. Safety guards and emergency stop systems are standard provisions per GB/T 15706 machinery safety guidelines. The working surface is typically ground to a roughness of Ra 3.2 or better to prevent rubber slippage during compression. Cooling channels through the roller body are optional for heat-sensitive compound processing, though not confirmed for these specific models.

Primary applications include tire manufacturing where crushed rubber feeds calendering and extrusion lines, footwear production for soling material preparation, and rubber recycling operations for size reduction prior to devulcanisation or pyrolysis. Buyers are typically tyre makers, industrial rubber goods manufacturers, and recycling processors in Southeast Asia, India, and Africa. The YB-450X650 suits integrated production lines with outputs exceeding 2 tonnes per hour, while the YB-250X500 serves batch operations and smaller compounders. Trade terms mentioned include FOB and CIF from Chinese ports, though specific port, loading time, and payment instruments require direct negotiation. Documentation for import includes commercial invoice, packing list, bill of lading, and certificate of origin; machinery may require CE or local safety conformity depending on destination market.

Zhanjiang Weida Machinery Industrial Co., Ltd. is located in Zhanjiang, Guangdong Province, China, with postal address 524000. The company's trust tier is classified as 'harbor' with a 0.00% response rate and 0 average response hours, indicating minimal or no recorded engagement through the platform's messaging system. This absence of response data means buyers should initiate contact through multiple channels, including direct email, telephone, or trade show meetings, to assess supplier responsiveness. The supplier lists model-specific rubber crushers rather than generic machinery, suggesting some degree of product focus, though the extent of their specialisation in rubber processing equipment versus general machinery manufacturing is not stated.

The supplier's profile does not disclose manufacturing floor area, employee count, annual revenue, export percentage, or domestic versus international sales split. No ISO certifications, quality management systems, or third-party audit credentials are mentioned in the available data. The source description references 'manufacturer direct pricing' and flexible MOQ, but these are marketing claims without substantiating figures. Buyers should verify factory existence through video calls, request reference customers in their target market, and confirm whether Zhanjiang Weida owns production facilities or operates as a trading company. The Guangdong location places the supplier within China's southern manufacturing corridor with access to Shenzhen and Guangzhou ports, though the specific export port for these crushers requires confirmation.
