How Does the Jaw Crusher Handle Primary Crushing?
The tracked mobile jaw crusher is defined by its 1,000mm x 600mm feed opening, which accepts rock and rubble up to 500mm in size. This geometry is optimized for primary crushing, where the material is reduced to a typical 100mm to 150mm product size. The crusher operates at a throughput of up to 250 tonnes per hour, depending on the material's bulk density and hardness. The hydraulic drive allows the operator to adjust the jaw speed from 220 to 300 rpm, which is critical when processing recycled concrete with embedded rebar or quarry rock with variable fracture toughness. The unit's 34,000 kg operating weight provides the necessary inertia to handle large feed lumps without excessive vibration, while the track-mounted chassis enables movement across uneven terrain.
Typical applications include primary crushing in aggregate quarries, processing of demolition debris, and recycling of construction and demolition waste. The 500mm maximum feed size makes it suitable for accepting run-of-crusher material from excavators or wheel loaders without the need for a separate scalping screen. The integrated grizzly feeder with a 1,200mm wide belt and a two-stage pre-screen removes fines below 40mm before they enter the crushing chamber, reducing unnecessary wear on the jaw plates and increasing the net throughput by up to 15%. This is particularly beneficial in recycling applications where the feed contains a high proportion of soil and small fragments.
Compared to smaller track-mounted jaw crushers with 700mm x 400mm feed openings, this model offers a 2.5 times larger feed area and a 40% higher throughput, making it suitable for medium to large-scale demolition projects. Unlike static primary crushers, the tracked chassis allows the unit to be repositioned within the quarry face, reducing the need for haul trucks and lowering operational costs. The 242 kW engine meets EU Stage V emissions standards, enabling operation in urban areas with strict emission regulations. The remote-controlled tracking system allows the operator to move the crusher while standing at a safe distance, improving site safety during repositioning.
- Feed opening of 1,000mm x 600mm accepts up to 500mm feed material, reducing the need for secondary breaking.
- Hydraulic drive with variable speed control (220–300 rpm) adapts to different material hardness and recycling conditions.
- Integrated pre-screen removes fines below 40mm, increasing net throughput by up to 15% and reducing jaw plate wear.
- EU Stage V engine (242 kW) complies with urban emission regulations, allowing operation in city centers and sensitive environments.
