The type of mining relates to hard rock,eluvial, or placer; alluvial deposits. The capital budget you have to invest in buying your equipment with dictate the scale at which you want to mine and influence the long-term operating costs of your mining operation.

Since most of the information online provides lists of gold mining equipment for amateur level mining with equipment like: gold pans, metal detectors, mini sluice box, blue bowl, geologist rock pick, soil scoop, hand screens/classifiers. The items listed just now fall closer to gold prospecting tools and equipment than actual mining.

I will present here what I consider are major equipment lists for 3 types of mining operations. Remember now, a metallurgist is writing. This will not be flawless and since my speciality is process equipment, that is mostly what will be discussed.

Some amateur level gold prospecting equipment such as metal detectors are often classified as mining equipment by small miners/prospectors operating as a hobby. These items include but are not limited to:

mineral processing equipment | african pegmatite

mineral processing equipment | african pegmatite

As a leading supplier, processor and miller of a wide range of minerals, African Pegmatite has the technology and ability to manufacture high grade minerals to any customers exacting standards. For a broad array of materials whether they need grinding, granulating or drying, African Pegmatite stands ready with the cutting edge equipment and specialist knowledge required to get the job done.

There are a number of machines ideally suited to processing of a variety of minerals, depending on the type of mineral involved. This article will give an overview of some of the wide range of mineral refining processes available through African Pegmatite.

Many of the processes are available on a toll basis, meaning that African Pegmatite will mill, dry or refine a product that has been supplied by a third party. Economically attractive, these services mean that customers do not need to invest in their own dedicated processing equipment and can take advantage of African Pegmatites extensive experience and wide machinery selection, ensuring the optimal processing pathway for any mineral supplied. Using a dedicated mineral processing company for custom milling and refining services will ensure a superior final product, produced to a customers exacting specifications.

The machining of minerals is a topic as broad as it is essential to modern industry. The choice of techniques is governed by many factors, not limited to but including, the identity of the mineral itself, the desired final product and machine suitability, amongst others. Machining can be broadly thought of in four categories; crushing, milling, granulating and heating. For a particular outcome, these may be sequential, or only one or two processes may be used. Machining is a high energy process that requires highly specialised equipment and highly trained operators.

Crushing/grinding is typically the machining technique used in the first instance with freshly mined/quarried rocks, ores and minerals. Tolerant of large sized raw input materials, crushing can be thought of as a cruder technique than milling for example, as it produces comparatively larger sized output products; such as aggregates for construction and infrastructure building, small to medium sized rocks for landscaping, and materials that can be further processed using other techniques.

A cone crusher operates by dropping hardcore materials down a funnel onto a steel cone-shaped cylinder spinning in an off-centre pattern. The cone is set to a predefined crushing measurement, usually of a 4:1 to 6:1 reduction ratio. The materials work their way down past the cylinder which crushes them to the desired size before releasing them into the filters below. Rocks can pass through up to four different sized crushers in order to achieve the desired size. When a rock passes through a crusher its size is further reduced each time, this is referred to as the ratio of reduction.

Unprepared rocks and freshly mined ores, alongside other aggregates, are the most common applications that cone crushers are used for, producing rocks for landscaping, erosion control, road building, and ore mining.

There are two main types of roller crushers. The first is where the rolls of each two parallel rollers are rotating in the opposite direction and where one roll is spring loaded. In this instance, the mineral particles are trapped and crushed as they pass between each of the two rolls.

The second type is known as high pressure grinding roll (HPGR), in which each of the minerals or rocks are reduced in size by using compressive and interparticle pressure which is mathematically configured beforehand.

A jaw crusher is the main type of primary crusher utilised in a mine or ore crushing facility. The size of the feeder at the top of the crusher usually denotes the size of the jaw crushers and the size of unprepared aggregate or ore the machinery can handle. As the name suggests, the jaw crushers are aligned into a V shape and act with a jaw movement using hydraulic or pneumatic compression to crush materials to the desired size.

Essentially, the outward motion of the jaws allows gravity to draw the rocks (or material) down further into the V-shaped jaws where they become trapped. Then the inward motion of the jaws crushes the rocks. This process continues until each rock has reached the base of the machine and is finally compressed to the right size. The rock will remain in the machine until it has been sufficiently crushed to allow it to pass through the gap at the base which only allows a specific gauge on size.

In contrast to crushing, milling is a technique that produces a much finer physical product. Oftentimes, minerals are required for use in a ground or powdered form, making them much easier to add to the process that needs them. Be it a refractory material for furnace lining production, ground glass for filtration applications, or milled anthracite for solvent extraction, milling is the key to getting the right product.

With in-house fully customised equipment to effectively mill all across the mineral spectrum, easily down to grind sizes as low as 45 m, African Pegmatite offers the broadest tolerance of materials and reliable results at any scale. The following milling technologies are offered:

The ball mill could be thought of as a type of grinder. The principle of which has been used for hundreds of years, but has been refined in the modern era to be more tolerant of a wider profile of minerals, operating for longer time periods, offering better performance. The machine is partially filled with balls and serves to offer repeated and constant impact using the movement of the balls to crush and grind the materials.

The types of material that the balls are made of is dependent on the type of mineral to be treated. Steel is the most widely used material, but stainless steel, rubber or ceramic could all be used depending on the material that needs to be ground and the desired product outcome.

The balls are placed inside a long hollow cylinder which is about as long as it is wide, the tube is often lined with abrasive wall linings or in some cases an incredibly hard material like manganese. The cylinder is rotated around a central axis, the minerals inside are slowly spun along with the ball contents and are subjected to constant impact and attrition from the balls to ultimately crush and mill the contents to a specific size or powder ratio.

Water powered hammer mills were used as far back as 488 CE. Essentially, a hammer mill is a steel drum housing a horizontal rotating shaft mounted vertically or horizontally on which numerous hammers are mounted. They can be used as a secondary or tertiary means of crushing, and the primary means on occasion.

The hammers are spun on their axis at high speed and as the material is fed in through the hopper it shatters on impact, all the way down the mill, becoming smaller as it goes. This can be a small or larger scale. Fragments exit through the bottom of the mill, and can then be sieved or filtered depending on the size requirements. Medium to large sized aggregates are most suited to this technique.

The Raymond mill is a superior choice for small scale powder making projects and is used widely in the mining industry. The Raymond mill will easily satisfy the demand for 80 to 600 mesh (180 to 23 m) powder tasks.

A large upright cylinder houses a central shaft, which spins at high speed. The shaft has attached to it a number of heavy high-speed rollers that act with a grinding motion as large material particles are fed into the side of the machine. The result is almost instant powder residue resulting from the grinding motion which is then fed out using specialist filtering tubes.

Common applications that use Raymond mills include barite, calcite, potassium feldspar, limestone, talcum, dolomite, gypsum, marble, clay and glass. Such wide material scope is testament to the Raymond mills extensive utility.

Attritors can be found in many sizes and a variety of places, from small scale laboratories or pilot plants to factory production floors. Attritors, also referred to as stirred ball mills, work by use of shear and impact methods on a given material by another stronger media.

The attritor mill is similar to the ball mill and uses much the same principles, but with slight variations. Essentially, the material is put into a fixed tank which contains a grinding media, this media could be carbon steel, ceramic, stainless steel, tungsten carbide, ceramic or, most commonly, chrome steel balls. These balls are then violently agitated, propelled by a fast-moving shaft with arms which causes them to impact upon and break up mineral material. After a period of attrition the material is pulverised, often into a fine powder.

Often thought of as similar to milling, to which many extents it is, granulating is the process by which materials are processed to granule size, as opposed to all the way to a powder. Granules are particle sizes larger than powders and typically find applications in areas such as filtration and construction materials. Many of the aforementioned milling techniques can achieve a granulated product if the machinery is suitably configured, however African Pegmatite provides a range of decks and screens to ensure clearly defined particle sizes. Shaker tables and vibrating screens use the principles of size exclusion, bulk density and specific gravity to ensure particle size.

Sometimes an overlooked aspect of mineral processing, drying is often an essential component in the production of a refined mineral that is ready to use by the customer. Future applications may be sensitive to moisture, for example excess steam could be generated during thermal molding processes. African Pegmatite offers solutions to moisture problems, with the capacity to reduce moisture in a given mineral powder to less than 1%. In addition, heat treatment/drying can drive off contaminants which may be residues from earlier processing, or those which may inhibit a further process; and drying can remove bacteria and pathogens for some of the most sensitive applications. The primary method of drying is via the use of a rotary dryer, which provides comprehensive and efficient removal of moisture by tumbling the mineral through drums and through heat of between 200 to 250 C. Naturally, this process is applicable to materials with a higher melting point than the operational temperature of the dryer.

This article only scratched the surface of the broad field of mineral processing, and highlighted some of the broad range of equipment and processes on offer. With all this in mind, African Pegmatite can, therefore, cover almost any crushing or milling task that is required. It is important to note that a full programme of processing may require the use of multiple pieces of machinery and work systems - all of which can be accommodated for.

Future articles will look deeper into some of these processes and provide a more detailed discussion on the services offered by African Pegmatite, from contract and toll milling all the way through to specialised granulation and drying.

African Pegmatite is a leading supplier and processor of minerals and has the ability to refine a broad range of materials to the exact specifications of a customer, including milling and drying services on a toll basis. Utilising proven and reliable processing methods as well as cutting-edge technologies and a knowledgeable and specialised staff, African Pegmatite is the ideal mineral processing partner.
