Boost sample preparation efficiency with coarse and fine crushing from FLS

Essa® RC2000 is a proven mid-range secondary crusher that has a maximum feed size of 30 mm. The RC2000 is designed for fast and controlled size reduction of various sample types. With a tight footprint, it’s the smaller of the two rolls crushers in our Essa® fine crushing range.

The standalone configuration of the RC2000 allows for simple and low-cost installation. It’s mounted on a sturdy floor stand and fitted with a feed hopper and easily accessible aluminium sample draw. This ergonomic design makes it easy to use and offers your workers greater protection.

Other safety features include mesh guarding fitted on the feed hopper and a dust extraction point to remove airborne dust from the operating environment.

This rolls crusher is a dependable and sturdy mid-range secondary crusher that has a maximum feed size of 40 mm. It’s also packed with considerably more power. 
We’ve made the RC3000 versatile, giving you two installation options to choose from: a floor mount standalone version suitable for batch use, or a low-profile bench mount version. If you need continuous use, such as in mechanical sampling plants, automated laboratories or pilot plants, the bench mount version is the ideal configuration for you. Both configurations are easy to install and provide you with a safe, sturdy, ergonomic crusher that gives you accurate and consistent results while producing hardly any dust.

Like the smaller model, the RC3000 is fitted with a range of safety and usability features. Your workers will appreciate the contra-rotating rolls, fitted feed hopper, easily accessible aluminium sample draw, mesh guarding, and dust extraction point.

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.

Choose to fit your HSC550 Jaw Crusher with manganese steel, stainless steel, tungsten carbide or special steel grade jaws, on request. You also have the flexibility to collect crushed material in a drawer with a capacity of two litres, or, in the case of large samples, to work without a drawer.

With the ability to crush material with a feed size of up to 90 mm, our HSC590 Jaw Crusher is a real workhorse. It crushes to a final fineness of < 4mm and with a selectable gap width of 0-30 mm.

Easy to use and safe, the jaw of the HSC590 can be quickly and easily locked and unlocked using a wide non-slip handle to speed cleaning and inspection of the crushing chamber, and to make cleaning hassle free. A width display ensures any adjustment to the gap width also happens quickly and easily. This includes zero-point adjustment for wear compensation.

Choose manganese steel, stainless steel, tungsten carbide or special steel grade jaws, on request. You also have the freedom to collect crushed material in a drawer with a capacity of five litres, or to work without a drawer.

The Essa® JC1000 Jaw Crusher is the smallest of the range. It is a medium-duty, entry-level machine designed for crushing smaller samples across a wide range of applications. The JC1000 accepts a variety of sample types up to 85 mm. It has a good reduction ratio with 6 mm product size and 250 kg/hr throughput. A single toggle and easy jaw gap adjustment add to its uncomplicated operation and control features. The jaw plates are made from hard-wearing BISALLOY® Wear steel, further reducing sample contamination.

The Essa® JC2000 Jaw Crusher is dependable, hard-wearing, and has proven itself in exploration and grade control primary sample crushing across the exploration and mining industries. Suitable for drill core, rock chip and grab samples, it is the industry standard crusher for the geochemistry laboratory.

The crusher accepts samples up to 110 mm and has a very good reduction ratio with 6 mm product size. It delivers rapid and powerful crushing at 500 kg/hr throughput. Choose an upright, stand-alone configuration or a low-profile bench-mountable version.

The heavy-duty, general-purpose Essa® JC3000 Jaw Crusher is a well proven, highly productive primary crusher used in sample preparation and plant applications. More powerful than the JC2000, it is suitable for higher workloads and can handle large core and lump crushing. It effectively crushes soft to very hard ore, drill core, rock and similar particulate.

The single toggle JC3000 has been tried and tested for analytical and metallurgical laboratory use. It is well regarded as a high performing, low maintenance choice. It has large input feed size up to 170 mm, with an efficient reduction ratio with 24 mm product size and rapid crushing at 3000 kg/hr throughput.

Choose from upright stand-alone or low-profile configuration.

The rugged and dependable Essa JC5000 Jaw Crusher is the largest model in the Essa® range. It has a throughput five times as large as the next model down, at 15,000 kg/hr. It also has a larger input feed size up to 250 mm, with a 30 mm product size.

Typical applications include primary crushing of large lump ore in sampling stations and pilot plants, the pre-crushing of materials being prepared for analytical or metallurgical laboratory use, and in industrial production facilities. The JC5000 is suitable for soft to very hard ore, rock and large industrial particulate. Its flexibility of use allows for continuous or batch use in laboratory and plant applications. It is a highly desirable crusher, requiring fewer processes and less handling.
