High weir spiral classifier opening height, the opening size of the next grading machine, grading machine opening height, size of the opening on the grader during equipment installation site production, in many plant, because the equipment is installed in the classifier size of the opening level of no adjusted, spiral classifier, and workers during operation and do not pay attention, but also affect the grinding invisible job. Under grader opening low, ore precipitation area is relatively large, so the large amount of sand back, relatively fine grinding fineness, Zhuhai grader, grader at opening large ore precipitation area is relatively large, the flow is more gentle, So back to the amount of sand will be large, relatively fine grinding fineness, grading machine opening lower, return sand is relatively large, tcf grading machine, grinding fineness relatively thinner, grading machine opening large relative return sand is relatively large, ground fineness relatively thinner. Otherwise the opposite. Angel machinery companies win the trust of customers first, honest-cast brand. The main production full set of processing equipment. Ball mill, energy-saving ball mill, overflow ball mill, lattice-type ball mill, flotation machine, magnetic separator, grading machines, dryers and processing equipment auxiliary equipment. Welcome to inquire order. Two consecutive days of severe pollution, Zhengzhou air is drunk people, and in this weather, small still wore Kulie haze to work for you on some knowledge grader, customers and friends must be more support for Angel Xiao Bian yo! Today, we bring back the amount of sand is reduced when spiral classifier work reasons. In the process of sand production line, the spiral classifier using it properly plays an important role. We can verify the amount of sand from the back of the fineness number and ball mill, the following mechanical Henan Angel on these issues to tell us something; first spindle lifting height is an important factor affecting the amount of sand return, normal production Requirements grading machine spindle into place. Because some of the concentrator in the equipment maintenance, ore grading machine not clean, the sink set in a long time, heavy sludge than real, fc grading machine, grading machine spindle at the lower levels, because they do not care, did not spindle completely down, resulting in less than normal amount of sand back situation. Also do not put down the spindle may be due to the spindle long time to clean up oil, so during the operation should be noted. Zhuhai grader, fjc grader, Angel Machinery (certified merchants) are provided by Gongyi City Angel Machinery Manufacturing Company Limited. Road Zhiyuan, temper forward. Gongyi City Angel Machinery Manufacturing Co., Ltd.
