One Size, Color Black. Pneumatic Tamping Machine for impact ramming of foundry sand and for compacting bricks and concrete in construction. Designed for large casting sand types and heavyduty tamping tasks using compressed air. Key benefits Fast, efficient tamping: impact frequency and large working capacity reduce time to consolidate sand and concrete. Durable construction: Forged components deliver wear resistance and shock resistance for extended use on job sites. Simple pneumatic operation: Runs on compressed air and connects to standard air compressors and hoses for easy integration. Versatile applications: Suitable for foundry sand ramming, mold consolidation for large castings, and brick or concrete compaction in construction projects. Specifications (D9) Model identification: D9 Pneumatic Tamping Machine Length: 9501095 mm Weight: 6 kg Use air pressure: 0.63Mpa Impact frequency: >=14 Hz The use of gas: <= 13 L/S Piston stroke: 100 mm Piston diameter: 25 mm Trachea inner diameter: 13 mm Hammer head diameter: 42 mm Package included: 1 x D9 Pneumatic Tamping Machine capacity specification Length: 1180 mm Weight: 9 kg Use air pressure: 0.63Mpa Air consumption: 0.65 l/s Impact frequency: 600 Hz The use of gas: <= 15 L/S Piston stroke: 207 mm Piston diameter: 32 mm Trachea inner diameter: 13 mm Hammer head diameter: 54 mm Materials and performance Forged from quality materials for long service life, wear resistance, and strong shock tolerance. impact frequency and substantial piston stroke options enable rapid and thorough tamping across a range of materials and mold sizes. Compatible with standard compressed air systems; requires an air supply at 0.63Mpa and a hose with at least 13 mm inner diameter. Typical applications Foundry work: Impact ramming of casting sand to consolidate molds for large castings and improve mold strength before pouring. Construction: Compacting bricks and precast concrete elements during molding and forming operations to improve density and dimensional stability. Heavyduty tamping: Onsite consolidation of fill, mold cores, and other mass sand or aggregate preparations where pneumatic impact ramming is required. Operation notes Ensure air supply meets the specified pressure and flow requirements for the selected specification. Use a hose with 13 mm inner diameter to match the trachea requirement. Select the specification that matches job scale and required impact frequency and stroke. Package contents 1 x D9 Pneumatic Tamping Machine
