·A variety of dust control methods are often applied in coal mines among which the application of wet scrubbers has proven to be an efficient technology for the removal of dust in airstreams rather than diluting or confining the dust In this paper a wet scrubber design was developed Based on a self designed experimental test platform the total dust concentration
·the excavated coal to the beam stage loader BSL BSL transfers the coal to its crusher and the crusher reduces the size of the coal transported from the face As a result belt conveyors convey the coal out of the mine On the other hand the operation area is supported by shields in mecha nized longwall faces Besides shields enable the
·When metal gets introduced in the coal crusher then crusher draws a large amount of current to increase the torque this large inrush of the current into the windings may cause excessive heating
·Coal Pulveriser Mill Function and Operation details Pulverizer as shown in is used in power plant to reduce the size of the incoming raw coal to a fineness that will efficiently burn in a furnace [1] Fig 1 H P Pulveriser actual view and parts As in the raw coal normally 25 mm is fed into a
Mozambique Vale the Brazilian based parent of Toronto based mining exploration company Vale Canada Ltd has signed a major contract with to deliver 110 heavy duty slurry pumps to its Moatize coal mine in Mozambique
·Exploring the performance of coal based solid waste filling is mainly characterized by its compressive strength Hao et al 2021a Uniaxial compressive strength The large gangue is crushed by a small jaw crusher and screened into coal gangue with a particle size of 0 5 mm through a standard screen The cemented block in the material is
·Based on the distances between the 3# coal roof and major aquifers within the scope of the 302 panel area as shown in Table 1 it is observed that the Zhenwu Cave Sandstone is located at a distance of to m from the coal seam which is too close to be protected through goaf backfilling On the other hand the Qili Town Sandstone is
·A combination of Taguchi experiments NN and CFD is used to study the impacts of coupling between characteristic parameters on the classification performance of the straw micro crusher s classifying device to determine the influence of each characteristic parameter on the classification performance and predict the optimal parameter combination
·Construction of typical coal and rock particle models To enhance the realism of the particle models in the discrete element model of the coal wall three primary shapes of coal and rock particles
·When metal gets introduced in the coal crusher then crusher draws a large amount of current to increase the torque this large inrush of the current into the windings may cause excessive heating
·crusher performance This will enable experiments and tests of virtual prototypes in early product development phases It will also actualize simulation and provide further understanding of existing crushers in operation for optimization purposes The platform is based on the Discrete Element Method DEM which is a numerical technique
·The influence of rock strength properties on Jaw Crusher performance was carried out to determine the effect of rock strength on crushing time and grain size distribution of the rocks Investigation was conducted on four different rock samples namely marble dolomite limestone and granite which were representatively selected from fragmented
4 ·One of the original equipment manufacturers OEM for crushers will soon roll out a new gyratory model The improvements included in it were based on what the OEM and the mines have learned in the last 20 years Making the decision as far as replace or rebuild is not always easy Rebuilding these machines requires an investment and time
·With the aim of solving the problem of coal congestion caused by big coal blocks in underground mine scraper conveyors in this paper we proposed the use of a YOLO BS YOLO Big Size algorithm to detect the abnormal phenomenon of coal blocks on scraper conveyors Given the scale of the big coal block targets the YOLO BS algorithm replaces the
·Synergistic performance of microwave activated coal gangue with limestone in low carbon cement Firstly the raw CG is dried in a blast drying oven 100 °C 2h then crushed and ground using a crusher particle size range 30 100 μm The strength of coal gangue based cementitious materials under different microwave activation
·coal dust is typically present Careful protection of this asset is critical to reliability and productivity as well as personnel safety Solution Protect coal pulverizers with synthetic lubricants designed to minimize maintenance through their outstanding viscometrics The use of high performance synthetics can help limit frictional
·In this paper based on the coarse broken iron ores in the rotary crusher the ore particle model was established by using DEM software The dynamic characteristics of the model were simulated by combining with the three dimensional cone crusher model in order to study the influence of relevant parameters on the performance of the crusher
