The mobile jaw crusher with a capacity of 700 tons per hour (TPH) represents one of the most robust and efficient solutions in modern crushing operations, particularly in large-scale quarrying, mining, and construction waste recycling applications. Among the various models available in the market, units such as the Terex® Finlay J-1580 or the Metso Lokotrack LT1213S are often cited for achieving or exceeding this throughput when properly configured and fed with suitable material.
These high-capacity mobile jaw crushers are engineered to deliver maximum productivity while maintaining mobility and ease of operation. The core component—the jaw crusher—is typically a heavy-duty single-toggle design with deep crushing chambers and optimized kinematics to ensure high reduction ratios and consistent output. For instance, the Metso Lokotrack LT1213S features a Nordberg® C1213 jaw crusher capable of processing up to 700 TPH depending on feed material characteristics, moisture content, feed gradation, and discharge settings..jpg)
Mobility is achieved through tracked undercarriages equipped with diesel-electric or hybrid power systems, allowing rapid deployment across sites without disassembly. These units often include integrated vibrating grizzly feeders (VGF) that pre-screen fines and regulate material flow into the jaw chamber, reducing wear and optimizing throughput. The Terex Finlay J-1580, for example, incorporates a heavy-duty vibrating grizzly feeder with variable amplitude control to match varying feed conditions.
Crushing efficiency at this scale depends heavily on feed material properties. Hard rock materials such as granite or basalt will yield lower throughput compared to softer limestone under identical settings. According to technical specifications from Metso (now Metso Outotec), the LT1213S achieves 700 TPH when processing limestone with a feed size up to 90% passing 450 mm and closed-side setting (CSS) adjusted to around 100–150 mm..jpg)
Environmental and operational considerations also play a role. Modern 700 TPH mobile jaw crushers are designed with dust suppression systems, noise-reducing enclosures, and onboard diagnostics for real-time monitoring of engine performance, fuel consumption, and wear part status. Many models comply with Tier 4 Final/Stage V emission standards through advanced diesel engine technology.
In practical applications, these machines are often used as primary crushers in multi-stage crushing plants. Their ability to be relocated quickly makes them ideal for large infrastructure projects such as highway construction or open-pit mining where operational zones shift over time.
It should be noted that achieving sustained 700 TPH output requires proper upstream logistics—adequate loading equipment (e.g., large excavators or wheel loaders), well-graded feed material, minimal tramp metal, and minimized downtime through preventive maintenance.
In conclusion, mobile jaw crushers rated at 700 TPH are high-performance machines designed for demanding environments. Their specifications are grounded in proven mechanical engineering principles and field-tested performance data from manufacturers such as Metso, Terex Pegson, Sandvik, and others. When deployed appropriately within well-planned operations, they significantly enhance productivity and cost-efficiency in bulk material processing industries.
