For its extensive practical experience, 911 Metallurgisthas a clear understanding of what successful mineral processing engineering is and how to go about achieving it. Your goal is the production of a material that is marketable and returns you and your investors sustainable revenues.
Although improvements to the metallurgical processes have been made over the years the fact is that the unit operations, the machines, those too often called black boxes involved have not evolved or changed much since inception. Ore is reduced in size, chemicals are added and minerals separated and upgraded to produce a marketable product. Much of this process is mechanical and generally mistaken for some dark alchemy.We are the Anti-Alchemists.
Our vast experience has been gained through operation and start-up of both small and large scale mining/metallurgical operations in a range of commodities in thebase metals (Cu, Pb, Zn) and theprecious metals (Au, Ag,)
A solid metallurgist understands, the most important aspect of an operating process is its stability. Simple to say, but generally the most ignored in mineral processing. Linked unit operations require each to be stable, and each contains a different set of variables that have to be contended with. Thanks to some degree of stability: operating changes can be made and evaluated; increases in throughput can be made; and equipment performance improved. The more complicated the processes become, the more difficult it is to achieve and maintain stability. In mineral processing, unlike most processing operations, we have limited control of the main input, the feed ore. In most cases this inherently is variable and usually outside of the processors control.
Because you are too close to your own story, you might not see the forest for the trees and have chaos mistaken for stability. We, you, and your group have been battling plant problems for weeks, you start to accept chaos as a daily state of affair and consider it your new stability.
Each mineral processing plant is different: with varied ore types, mining equipment, and management (operating) philosophy. The evaluation and prioritisation of variables that affect the plant performance is the primary function. Implementing changes within the constraints imposed can be difficult, as resources may be limited.
Invariably the ability to solve problems can be confusing due the large numbers of variables that may impact the processes. In most cases problems are not metallurgical in nature but rather operational and mechanical. Problem solving is a process and in many operations this ability is absent. All too often many changes are made together without a solution resulting, on more confusion. Most plants learn to live or survive their problems, not to solve them.

Essa Jaw Crushers have set the industry standard for over 30 years so you can be assured the designs have stood the test of time. They offer fast sample throughput with good reduction ratio and reduced sample contamination.
The crushers are easy to maintain and repair, and have hard-wearing parts, such as the long-life roller bearings and strong jaw plates. These decrease downtime and maintenance costs important factors that affect your bottom line. Additionally, their simple mechanical design makes them easy and safe to operate.
With high productivity and low maintenance costs being a priority, Essa has designed these sturdy machines to operate efficiently and safely. The mechanics have been kept simple for easy repair so that downtime is kept to a minimum.
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. Known in the industry as a steady-going and reliable machine, it is productive and hardy, with reduced operating and spare parts costs.
To maximise your available space, the JC1000 has a compact footprint. It is mounted on a sturdy floor stand and is fitted with an ergonomically designed feed hopper and easily accessible aluminium sample drawer. It features a simple stop/start button. Along with a dust extraction point to remove airborne dust, these features improve the operating environment and reduce sample contamination.
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 known as a workhorse in the industry, and for good reason. It 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.
Its two installation options offer improved flexibility. Choose an upright, stand-alone configuration or a low-profile bench-mountable version. Both can easily be configured to operate in a sampling station or pilot plant application.
This crusher represents excellent value and promises high productivity for any laboratory, field or plant application. The mechanically simple single toggle design is reliable and easy to maintain and repair.
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.
You are offered flexible installation options, with the machine available in upright stand-alone or low-profile configuration. The low-profile configuration has a fabricated steel base for mounting on a support frame or concrete footing.
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.
Standard features include rugged, fabricated steel construction, electric pre-wiring with an IP65-enclosed stop/start and motor protection station. The vertically serrated chrome steel jaw plates are reversible and interchangeable for extended life.
With safety a top priority, the JC3000s features include full drive guarding. The two dust extraction points remove airborne dust at the inlet and sample drawer, greatly improving the health of the operating environment. Theres also an ergonomically designed feed hopper and easily accessible aluminium sample drawer.
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.
The crusher has a number of features which make it easy to maintain and repair. These include the mechanically simple single toggle and the jaw gap adjustment mechanism. It offers extended wear part life with the reversible and interchangeable manganese steel jaw plates. The long-life roller bearings allow for a high load capacity and also decrease downtime and maintenance costs.
