The Tesab 824TR is a mobile impact quarry crusher designed for on-site aggregate production and processing. Tesab manufactures a comprehensive range of crushing, screening, and conveying equipment for the quarry, mining, and recycling industries. This unit combines a primary impact crusher with integrated screening and conveying systems to deliver finished product fractions in a single mobile platform.
The crusher is powered by a Volvo D8 diesel engine producing 188 kW (252 horsepower), operating at 1750–1900 rpm. The rotor measures 900 mm in diameter by 820 mm in length and operates at 678–756 rpm with a direct-drive configuration. The crushing chamber inlet accepts material up to 860 × 650 mm, with a rated throughput capacity of 200 tonnes per hour. The rotor is equipped with four replaceable impact bars and a single impact plate. Closed-side setting (CSS) is hydraulically adjustable via actuators and spring tension, and the unit incorporates engine load monitoring and rotor speed sensing.
The hydraulic system is supplied by two Turolla pumps—a flywheel pump (31.8/31.8/22.5) and a PTO pump (25.4/22.5)—delivering a combined flow of 263.7 litres per minute to a 350-litre main tank fitted with a hydraulic oil cooler. The machine runs a 1.6:1 overall transmission ratio.
Material processing continues through a single-deck grizzly feeder (800 mm wide, 3750 mm long) with adjustable bar spacing of 30–50 mm or 45–65 mm, powered by a Turolla 42.9 cc/rev motor. The screen deck measures 2000 × 4215 mm with a volume of 2.75 m³. Screened material is distributed across four conveyor systems: a main inclined conveyor (900 mm belt, 3006 mm discharge height), a fines conveyor (900 mm belt, 3015 mm height), an upper-deck conveyor (500 mm belt), and a reversible radial tail conveyor (400 mm belt) articulated through 180 degrees. A single-deck vibrating screen (2000 × 1100 mm) with SKF 22215 bearings and 8 mm stroke operates at 970 rpm and 5.05 G acceleration. A magnetic separator with a 559 mm belt and dual-pole, reversible drum completes the system.
The machine is mounted on rubber crawler tracks 400 mm wide and features a Bonfiglioli 709 gearbox with a MAG 85VP motor for independent ground travel at up to 1 km/h. All conveyor and processing belts are hydraulically foldable for transport and can be deployed on-site in approximately 20 minutes. In transport configuration, the unit measures 14.021 m long, 2.55 m wide, and 3.056 m high, with a total operating weight of 26,300 kg. Fuel capacity is 280 litres. The machine includes four full-size impact bars, external belt-tracking adjustment points, centralized lubrication stations, emergency engine shutdown systems, and pinch-point guards. This unit was manufactured in 2025 and has accumulated just 1 hour of engine runtime.
