We offer you four models to choose from for feed sizes up to 50 mm, 80 mm, 90 mm and 110 mm. All are well suited to high-volume mineral laboratories. Great value, high-volume crushing – Among the fastest and most precise crushers on the market, with a robust design and superior structural rigidity that delivers long life and excellent value for money. Low maintenance – You will appreciate the user-friendly reversible and interchangeable jaw plates. The grease joints are easy to reach, meaning simple greasing to save you time. Safety-focused design – Enhanced safety features protect your workers from dust exposure and fly rock. We also incorporate full drive guarding, auto-stop functions and offer you optional safety extras.
Our Essa® JC1250 Jaw Crusher is small but strong. Modelled off the tried and tested larger JC2501, the JC1250 can handle a high workload – up to 5 kg samples comfortably with a throughput up to 140 kg/hr. With a heavy duty 7.5 kW electric motor, the JC1250 equals that of our JC2501, but with half the crushing chamber width, providing extra torque and power for high volume mineral laboratories.
Our JC1250 can handle 80 mm maximum feed size and has a 40:1 reduction ratio for 2 mm minimum product size. On request, your JC1250 can include a safety feed hopper. Other safety features include a single dust extraction spigot that can be easily connected to your laboratory ducting system to protect your workers from dust exposure.
Our heavy-duty Essa® JC2501 Jaw Crusher allows for a larger feed size of up to 110 mm. It delivers greater throughput at 180 kg/hr, with a higher reduction ratio of 50:1 producing a consistent 2 mm product size. As well as greater productivity, the larger feed size reduces and often removes the need for pre-crushing, thereby reducing the risk of contamination and saving time.
While also well suited to high-volume mineral laboratories, we purposely designed our JC2501 to assist exploration laboratories undertaking two-stage sample reduction protocols. Like its smaller brother, it is designed for crushing ores, minerals, metallurgical samples, clinker, ceramics and similar particulate. It is built for speed and precision and has been tried and tested in the workplace.
Designed to crush and pre-crush hard and brittle materials, our HSC550 Jaw Crusher is suited for use with a wide variety of materials including alloys, slag, minerals, ores and quartz rock with a feed size up to 50 mm. A proven trouble-free performer, it reliably delivers consistent crushing results across all materials – crushing to a final fineness of < 4 mm and with a selectable gap width of 0 – 20 mm.
Smart engineering allows the HSC550’s jaw to be easily locked and unlocked using a wide non-slip handle. This facilitates easy inspection and cleaning of the crushing chamber. Additionally, a width display ensures easy adjustment of the gap width, including easy zero-point adjustment for wear compensation.
Safety features like no-rebound feed hopper and brake motor minimizes the risks of personal injury of the operator. The feed funnel cannot be reached into and can be simply hinged open for a fast cleaning of the grinding chamber.
A safety switch and brake motor ensure immediate shut-down if the unit is incorrectly opened or switched on. The fixed crushing arm can be removed easily for cleaning and jaw replacement.

FAQs for laboratory crushing equipment
Laboratory sample crushing is a size reduction process in which the goal is to break down raw materials into smaller, more manageable particles. This is an essential step in many mineral laboratories as it allows for representative sample division (splitting) to manageable volumes for further preparation (such as pulverizing, pressing, fusion, digestion, ect.) and analysis (such as XRF, XRD, titration, ICP, AAS, ect).
