High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals.
world class rolls of the highest quality for over 100 years. The WHEMCO companies in Pennsylvania and Ohio, USA manufacture a full range of mill rolls spun cast iron, cast steel and forged steel. Each of our roll manufacturing facilities has the expertise, equipment and experience to meet the most demanding rolling mill applications.
Designing a plate mill is far more than an exercise in mechanical engineering. It is a special and unique example of combining operational efficiency and metallurgical function. Plate products derive their properties from the deformation and temperature path they follow, and this means that the flexibility to roll a broad mix in a single mill

A brief history of metal rolling for sheet and plate products. On the first day of our Aluminium Rolling Technology Course I run a session entitled “Machinery and Process Overview”. Part of this covers the history of metal rolling from the first known drawings of a mill to the state-of-the-art rolling

Wear plates can be made of mild steel, abrasion resistant grades ranging from A514 to AR400 or AR500, flame hardened grades such as 1045 or 4140 or through
Crushers or rock crushers are machines used to reduce the size of rocks and stones in aggregates production, construction material recycling applications, and in mining operations. Metso has designed, engineered and manufactured crushers for more than 100 years.
Stamp mills are used by miners to crush valuable ore and extract the metals within them. Gold, silver, and copper are common metals that are found within ore, and stamp mills allow these metals to be released from rock for further processing and refining.
It is true that once you get to processing large enough amounts of ore you are likely to need environmental permits, etc., depending on the location you are working in. Most prospectors will choose to stay small, but even on a small scale, you can be processing gold-quartz ores recovering some very good gold and getting into real hard rock mining.
DOVE manufactures full range of processing plants for hard rock (Primary deposit) of gold and other metals and minerals mining projects. DOVE supplies hard rock processing plants with capacity range of 5-2000 Tons/Hour. Each processing plant is designed specifically according to the ore characteristics and the mineral composition, and for the
In the USA, Mt. Baker Mining and Metals (MBMM) builds high quality, robust, industrial machines used across many industries. Select an industry below to learn more
Anode A rectangular plate of metal cast in a shape suitable for refining by the electrolytic process. Anomaly Any departure from the norm which may indicate the presence of mineralization in the underlying bedrock. Anthracite A hard, black coal containing a high percentage of fixed carbon and a low percentage of volatile matter.
Mining drills are more common with underground mining. Drilling helps to bring material to the surface so that it can be further processed. Crushing equipment breaks down the hard rock or gravel so that it can be either transported or sent on the conveyor for sorting.
Gold Mining Equipment List. Making a complete list of gold mining equipment starts with defining the type of gold mining you are doing and the budget you have at your disposal. 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
Tunnels and underground excavations Tunnels and underground excavations Tunneling techniques: Tunnels are generally grouped in four broad categories, depending on the material through which they pass: soft ground, consisting of soil and very weak rock; hard rock; soft rock, such as shale, chalk, and friable sandstone; and subaqueous. While these four broad types of ground condition require
The Sandvik range of rock support drill rigs is designed for a wide array of hard-rock mining operations, tunneling and civil engineering applications. Thanks to on-board cement mixers, cement bag platforms, and optional cement silos and steel strand reels, the rigs can operate autonomously for
Hardox® wear plate is the world's leading abrasion-resistant (AR) steel. Hardox® is hard through and through, from the surface deep down to its core, giving you extended service life and high productivity in the most challenging environments.
Triple Roll Crushers. Triple Roll Crushers are ideal for producers who want to accomplish two stages of reduction in one pass. They can be used in coal, salt, coke, glass, and trona operations, among others. Triple Roll Crushers combine a Single Roll Crusher with a Double Roll Crusher to form a crusher that is capable of achieving a 6:1 reduction ratio in the primary stage and a 4:1 reduction
