Import Banbury Mixer For Rubber /Internal Mixer — Buy in Bulk from Supplier in China

The Banbury mixer for rubber from Qingdao Wanxiang Rubber Machinery Co., Ltd. is an internal mixer featuring a chilled mixing chamber construction for rapid thermal exchange during compound processing. Its inner wall carries hard chrome plating to extend wear life, while the rotor ridges and sides are protected by hard alloy build-up welding with subsequent hard chrome coating. Cooling and heating media pass through hollow passages in the rotor, with support for tangential linear type, mesh type, and synchronization type rotor configurations. The source does not specify chamber working volume, installed motor power, or rated batch capacity; buyers must request these to size the unit for production requirements.

The top of the rotor employs a constant hydraulic pressure seal with high-pressure lubrication and automatic low-oil alarm, a design that extends seal life and reduces unplanned maintenance. The upper bolt relieves pressure automatically under overload conditions to protect the machine from damage during extended high-torque operation. Both upper and lower working bolts are hard chrome plated for abrasion resistance, and the lower bolt contains internal hollow passages for cooling or heating medium circulation. These features indicate a machine built for continuous industrial duty, though exact pressure ratings, bolt dimensions, and alarm setpoints are not stated in the source material.

The discharge door uses a rotary oil cylinder for smooth operation and accurate positioning, while power transmission relies on a two-shaft output hard-tooth reducer with gear coupling or cross-type universal joint. This driveline is described as smooth running, efficient, low noise, and durable, though no decibel ratings, efficiency percentages, or service life metrics are provided. This internal mixer targets rubber compound manufacturers, tyre producers, and technical rubber goods factories where dispersion quality and thermal control directly affect product performance. All performance guarantees, warranty terms, and after-sales support scope must be confirmed directly with Qingdao Wanxiang Rubber Machinery Co., Ltd.

Qingdao Wanxiang Rubber Machinery Co., Ltd. is based at Lanzhou West Road, Qingdao 266300, Shandong Province, China. The supplier holds imported tier classification and harbour trust tier status on the platform. The response rate is recorded at 0.00 percent with zero average response hours, indicating no tracked communication history. No data is available on year of establishment, factory floor area, number of employees, annual turnover, export volume, or specific countries served.

The company lists a Banbury mixer with detailed mechanical features including chilled chamber construction, multiple rotor options, and hydraulic sealing, suggesting engineering involvement in the product description. However, no verified factory audit results, quality system certifications, customer references, or after-sales service commitments are included in the source. Buyers should independently verify production capability, request video factory inspection, and confirm that the described technical features are standard on the quoted model or optional upgrades before contract signature.
