Sandvik CJ412 Primary Jaw Crusher

The Sandvik CJ412 Primary Jaw Crusher is a heavy-duty, single-toggle jaw crusher designed for the first stage of size reduction in aggregate quarrying, open-pit mining, and construction material processing. With a feed opening of 1,200 × 830 mm and a throughput capacity of up to 1,100 tonnes per hour, the CJ412 accepts run-of-mine material from blasting operations and delivers a crushed product suitable for downstream secondary crushing by cone or impact crushers. The 132 kW to 160 kW drive range allows the crusher to be matched to the available power supply at remote Saudi quarry and mining sites, and the robust cast steel pitman, forged eccentric shaft, and hydrodynamic bearing lubrication system are engineered for continuous operation in the abrasive, dusty conditions typical of Saudi Arabian hard-rock quarries.

The CJ412 incorporates Sandvik's wedge CSS adjustment system, which allows the operator to change the output size setting without removing jaw dies or inserting shim plates — a significant maintenance time saving at high-production quarry sites where the jaw gap must be adjusted periodically to compensate for jaw die wear. The hydraulic shim adjustment option further speeds the process, reducing jaw-gap adjustment from a multi-hour manual task to a 30-minute hydraulic operation achievable by two technicians. The deep, symmetrical crushing chamber promotes consistent nip angles across the full jaw face width, improving material draw-in and reducing the proportion of oversized product that requires re-crushing.

Saudi Arabia's massive quarrying sector — driven by NEOM's requirement for tens of millions of tonnes of aggregate on the northwest coast, the Saudi Ports Authority's port expansion programme, and the National Roads Programme's highway construction — has created sustained demand for reliable primary jaw crushing capacity. The Sandvik CJ412's combination of high throughput, robust build quality, and relatively compact footprint for its capacity class makes it particularly well matched to the mobile and semi-mobile plant configurations favoured by Saudi aggregate producers who need to follow the construction front or relocate when quarry reserves are exhausted. Maaden's limestone quarrying operations that supply its industrial mineral and cement raw material requirements also operate heavy-duty primary jaw crushers of this class.

Razz Middle East supports Saudi customers in selecting the correct jaw die alloy — from standard manganese steel for limestone and soft aggregates to high-chrome cast iron for the abrasive quartzitic sandstone and basalt formations in western and central Saudi Arabia — and stocks the most common wear parts locally for fast exchange at planned maintenance intervals. Our field engineers provide jaw die change-out assistance, bearing and lubrication checks, and throughput optimisation advice for new plant installations and existing crusher refurbishment projects across the Kingdom.
