possible application. crushers queensminedesignwikicrushers play an important role in the material handling process for underground mine operations. the main purpose of a crusher is the size reduction of the feed. this size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces. there are two categories of crushers based on the way the force is applied to the material. for crushers of the first category apply force via pressure, the crushers of the second category apply force via impact. in underground mine operations, size reduction is necessary to facilitate the transport of the material to the mill. resizing of material often is the first step in the concentration process of the ore (de la vergne, 2003). since crushing is an important step of the ore concentration process, the selection and sizing of crushers should be given sufficient consideration during the mine design process. the objective of this article is to outline t see full list on minewiki.engineering.queensu the location of the crusher in an underground mine operation has a great impact on the design and development of the mine. the reason for this great impact is the role of the crusher on the design of material handling and skipping. two possible locations for an underground crusher exist: near the shaftand under the orebody. factors that determine the location of the shaft are the steepness of the orebody, the production schedule of the mine and the ground stress. it will take approximately six to twelve months to excavate, install and commission an underground crusher station (de la vergne, 2003). see full list on minewiki.engineering.queensu the material handling portion of crushing is the means by which the ore travels from the grizzly all the way to the skip in an underground mining operation. this can easily be broken down in to three sections, precrushing, crushing, and post crushing. precrushing is the movement of material through the grizzly, down the ore pass, and finally into the crusher itself. the crushing section is the ores movement through the crusher. this will vary, of course, depending on which crusher is utilized. lastly, the postcrushing phase is the movement of the material when it exits the crusher and gets released in to the ore bin and then continues its path towards the loading zone at the skip. see full list on minewiki.engineering.queensu in any operation that incorporates size reduction, selecting the primary crusher is vital to the overall success. the main parameters to first decide on a general type of crusher are the impact strength, product size and material hardness. the final design for a crusher will be selected primarily based on required capacity, feed and product size. it should be noted that further crusher selection could be defined based upon the location and the degree of mobility. technological advancements, from 1830 when the first crusher design was patented, have allowed todays crushers to take blasted rom (run of mine) feed up to 1500mm (60 inches) and reduce them to sizes ranging from 300mm to 38mm (mular et al, 2002). see full list on minewiki.engineering.queensu operating costs the primary operating costs of a crusher are parts and labour for maintenance, which can vary approximately twice as much as the power for the motor. gyratory crushers generally cost less than 1500 per hour to run, while jaw crushers cost less than 200, including electricity (infomine, 2008). rules of thumb a 42inch gyratory crusher produces approximately 2.4 tons per horsepowerhour (2.9 t/kwh). when idling jaw crushers consume approximately 50% of the power of full operation and gyra see full list on minewiki.engineering.queensu throughout the process of crushing, large amounts of dust are produced. dust has the capability of destruction of the equipment. left uncontrolled the dust is liable to increase wear and cause severe backups in the system thus causing expensive maintenance and heavy losses in production. even though compressive crushing results in higher dust creation then impact crushing, a large amount of dust is still created and must be managed and controlled in an efficient manner. regardless of the types of crusher utilized the movement of material through the crusher will create airflow, thus creating airborne particulates. this is not to say that dust always becomes airborne, but it is challenge that must be considered thoroughly. the most common ways of dust management in underground crushing are by water sprays and local exhaust ventilation. primary considerations while deciding which method of dust controlled shall be used are analysis of material type and arrangement around the crusher u see full list on minewiki.engineering.queensu in most underground mining operations, the material size of the excavated material will be too big for efficient transportation and processing. an underground crusher assures the size reduction to practical sizes and therefore plays an important part in the mining operation as a whole. there are two possible locations for an underground crusher: near the shaft and under the ore body. the location is mainly determined by the steepness and shape of the ore body, the depth of the ore body and the production schedule of the mine. the location of the crusher has to be determined in an early design stage, since it has a great impact on the other steps in the mine design. for underground crushing, three stages of material handling are defined: precrushing, crushing, and postcrushing. the precrushing stage prepares the material for the crusher. a grizzly will prevent oversize material from entering the crusher. a rock breaker reduces the size of this material to manageable sizes. the cru see full list on minewiki.engineering.queensu cavasin, c., reeves, s., english, j., resoort, p.
