The crushed ore is mainly copper ore, belongs to hard rock, feed block are below 750mm. Through field test, crushing system under normal operating conditions, the processing ability of the fully meet the design requirements and production requirements. Gape size is 150mm, output size -190mm, jaw crusher production capacity is 670t/h on average, minimum, maximum 766.7t/h 584.5t/h.
In the industrial test process, based on the above mentioned several indicators comprehensive inspection, jaw crusher in the correct operation and maintenance conditions, normal, stable operating condition. To ensure that only the jaw crusher various aspects of normal operation and improve production efficiency, crushing machine starting time, average 6S parking time average 58.3s; motor load current of 136A, voltage 379V, the actual power of 77.6KW, are in line with the design requirements; the jaw crusher in the running process of the components of the strength, stiffness, vibration, noise the fixed jaw, and a 4 bearing temperature indicators within the normal range.
Jaw crusher in mining, building materials, construction sector is mainly used as a coarse crusher and crushing machine. According to the material inlet width size is divided into large, medium, small three, inlet width greater than 600MM is a large machine, material inlet width in 300-600MM as midrange, inlet width less than 300MM for minicomputer. The jaw crusher has the advantages of simple structure, easy manufacture, reliable work, convenient repair and use. The jaw crusher bearing lubrication improvement has been improved.
