This is a good unit for faceters or anyone needing a complete, compact, portable lapidary unit to grind, cut and polish small stones.

This unit is speed controlled with a foot pedal which makes it great for freeing up your hands to create masterful pieces. The 55 pieces includes attachment for grinding, drilling and cutting. Comes in a sturdy case.

3" Posts and 5" Posts Slab Grabber Made to get the Slabs left in the nub-ends. One slab saved, usually pays for the SLAB-Grabber. Chucks level and parallel in your saw vise for uniform slices. Made of aluminum for blade safety, and positive nub holding. Made in the USA. 11" Posts Slab Grabber The larger version of the famous Slab Grabber introduced by Rock's many years ago. The 11" model will hold slabs in wide range of sizes: 3" to 11" in diameter. It will also hold those more common odd shapes as there are 12 different spots for locating the holding studs. Made of aluminum for blade safety.

Never run a diamond cutting blade dry as it can immediately damage your blade. Coolant oil should be kept clean and below 100 degrees F. Sludge should be removed periodically and replaced with fresh coolant oil so your cuts will be clean and your blades will not be damaged.

This Non-hazmat replacement oil excellent lubricating properties for blades and saw parts. It flushes sludge from rock easily, degreases easily and sludge settles in the saw tank well. Comes in a one gallon plastic jug.

A heavy duty water soluble synthetic cutting and grinding fluid with lubricant. Most advanced 100% synthetic coolant on the market today. 100% Biodegradable - mix with water only. Does not contain any nitrosamines, phenols, nitrates, sulfur, chlorine, phosphates or oil. Comes in a 8 oz plastic bottle.

A thermostatically controlled ceramic electric heater for melting and keeping your dop wax at the perfect temperature along with built in storage for your tools! Key Features include:

110/60HZ Wire Plugs UL Approved 3 Variable Speeds: - 0 to 5000 - 0 to 6400 - 0 to 8600 Work Surface Dimension: 6 9/16" x 6 9/16"

This is 5 - 1 1/2 mm diamond wire drills for drilling holes in stones. Use these to drill a hole for a bell cap, or to glue a finding in to hold a pendant or to run a cord through. These wire drills and burrs are made in the United States.

small scale hard rock grinder and upgrade plant: apt rocsmasha appropriate process technologies | mineral processing plants

small scale hard rock grinder and upgrade plant: apt rocsmasha appropriate process technologies | mineral processing plants

APT have added an innovative, cost effective new product to their Groundbreaker Range with this small scale hard rock grinder, the Roc Smasha. This small scale hard rock grinder offers a much larger range of miners the option of mechanical grinding. This means that more material can be processed increasing the probability for successful results. Its simple but functional design ensures easy use and maintenance features. The RocSmasha is portable and offers dry and wet grinding options, wet grinding ensuring no dust contamination on the environment following APTs environmentally conscience philosophy. The RocSmasha is sold alongside the APT GoldMasta gold sluice as well as 2 panning dishes, making this a complete, affordable gold liberation kit. Interchangeable screen cartridge for ware replacement and tuning is provided. This small scale hard rock grinder plant can be purchased on APT's online store here, and more can be read about it on our website here. The RocSmasha small scale hard rock grinder has a maximum feed size of 20mm with a throughput of 50-100kg/h. Portability makes it perfect for moving from site to site either for small scale production or exploration. A3kW Gasoline engine drive means low energy consumption. The hard rock material is fed through the feed chute using a small shovel or by hand, it is then crushed to size.The hard rock is reduced by RocSmashas unique offset blade hammers ensuring a high kinetic impact and early liberation of free gold from the inherent fracture planes, further reduction grind is imparted through the grinding path within the easy change screen plate cassette.

The wet slurry discharge is fed onto a GoldMasta Sluice over the unique APT GoldMatt ensuring very efficient recovery of free gold, (the APT GoldMatt being washed out at intervals for free gold collection). This small scale hard rock grinder plant is the perfect affordable mining solution.

For minerals such as tantalite, tin, tungsten etc. the screen plate cassette aperture can be changed easily to suit mineral type and a special type ofvortex mattingis placed in the sluice tray for best recovery of these minerals.

rock crushers

rock crushers

The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.

Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.

In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.

All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.

Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.
