The Sandvik Jammaster JM12 Crusher is a mobile tracked jaw crushing unit designed for primary and secondary stone and aggregate reduction. Sandvik is a globally recognised manufacturer of mining and construction equipment, known for building robust crushing, screening, and material handling systems for quarrying, demolition, and recycling industries.
This 2005 unit comprises a complete integrated crushing and screening plant mounted on a tracked chassis. The jaw crusher itself features a feed opening of 1200 × 830 mm, suitable for handling large run-of-mine or quarried stone. The primary electric motor is rated at 132 kW and is backed by a diesel-powered generating set: a Deutz diesel engine of 338 kW output coupled to a MECC ALTE generator operating at 400 V, ensuring operational independence on site.
Material handling is managed through a 10 cubic metre hopper feeding into an SBM feeder unit measuring 4290 × 1340 mm and powered by an 18.5 kW motor. Crushed material is discharged across an SBM pre-screening deck (1200 × 2000 mm) and then onto a main extraction conveyor belt (1400 × 11400 mm), with a sub-screen conveyor belt (1000 × 1800 mm) for finer material separation. The plant is fitted with a Rammer impact hammer (model C285) for secondary crushing or material conditioning. The overall width of the tracked chassis is 3 metres.
The machine is located in Italy and is offered in used condition consistent with its 2005 manufacture year.
