Run of mine ore is usually too large to be useful for construction or metallurgy Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations or facilitate mineral liberation; therefore in the aggregates and mineral processing industries run of mine ore is broken in crushing circuits by cone crushers
To accommodate this requirement the team decided to move the run of mine ROM pad and build the new circuit on the site of the old ROM pad While this achieved the brief of zero downtime it introduced a new challenge This means the crushers can be run tighter producing smaller product During the design stage the crusher output was
Typical crusher types evaluated for a specific project include Jaw Crushers Cone Crushers high speed Impactors or Hammermills and low speed Sizers Preparing the Run of Mine ROM bauxite for the grinding mill circuit must be completed
Independent miners particularly in South Africa often face the challenge of turning lower grade materials like 30/32 and 32/34 ROM Run of Mine or sweepings into a high quality 40/42 chrome concentrate
part of mine production Haul trucks transport and stack the mined ore into Run of Mine ROM stockpiles As the next step in the value chain to prepare a delivery to the client stockpile schedulers select a blend of the material in ROM stockpiles to be sent to the crushers for processing We refer to this blend
Primary & Secondary Crushing Vaal University of Technology • Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue • It is generally a dry operation and is usually performed in two or three stages • Lumps of run of mine ore can be as large as m across and these
Crushers are machines which are in operation to reduce large rocks into smaller rocks gravel sand They are predominantly used for the production of crushed mineral materials from stones In primary crushing larger run of mine materials for example rocks or ore lumps are reduced to smaller fragments If not already the desired end
In a single step TITAN ® double shaft hammer crushers crush run of mine ROM material to the required product size for either roller mills or ball mills TITAN ® double shaft hammer crushers are re nowned for their reliability and their state of the art heavy duty design that ensures a long service life

Welcome to Yadadri Engineering Systems YES designs and manufactures a wide range of crushing screening washing equipment and material handling systems for aggregate plants and ore metallic and non metallic processing The core strength of YES is its ability to interpret customer s crushed product needs and partner him in achieving his
Run of mine ore ROM is an important source of disturbances for mineral processing plants especially when autogeneous AG or semi autogeneous SAG grinding mill are used These systems are then used for troubleshooting and/or are implemented within feedforward/feedback control loops for crushers and grinding mills

ROM stockpiles to be sent to the crushers for processing Mo delling and optimization of run of mine stockpile recovery In 36th Annual ACM Symp osium on Applied Computing page 450 458
A primary crusher is designed to receive run on mine ROM rocks directly from the mines How Gyratory Crushers Work ROM ore from the mine is typically transferred by haul trucks which discharge into a feed hopper at the upper level; crushed ore is then discharged from the bottom shell assembly
Crushing and pulverizing reduces the material to a uniform size or to a graduation of sizes for immediate use or further processing The various manufacturers make specialized crushers for various processes such as reduction of long coils of metals into short lengths reduction in size of run of mine coal down to one inch and under in one operation and crushing of rock or ores
Magnetite ore known as Run of Mine ROM material is direct dumped by haul trucks from the mine into the primary crusher Primary and secondary crushers crush the ROM ore to a product size of <60 mm The crushed ore is then transferred to the Coarse Ore Stockpile COS which has a holding capacity of up to 500 000 tonnes of material for
As a part of its investigation into run of mine ore fragmentation Highland Valley Copper discovered the role of primary crushing in the optimisation of mill feed size Image analysis methods were used to quantify the effect of feed size on mill throughput and showed the in pit crushers to
Besides crushers and screens with associated equipment are needed for crushing and screening of ore to merchantable product Following blasting the fractured ore is known as run of mine ROM ore ROM ore is loaded by huge electrical shovels hydraulic excavators or front end loaders onto large capacity dump trucks which haul it to
