This product is mainly used for grinding medium hardness of ore, metallurgy, geology, mining, building materials and chemical industry departments and universities and scientific research units laboratory use.
B.the main working principle
This machine is mainly composed of the body, base, spindle, moving mill disc, fixed mill disc, end cover cover and hopper. The power is transferred to the belt wheel through the triangle belt to drive the spindle rotation, so that the grinding disc fixed grinding disc relative motion, so as to crush the sample. The discharge particle size can be adjusted by the size of the handwheel, spindle and other grinder clearance to control the purpose of particle size.The body is installed on the base, and its transmission part is composed of a transmission shaft, bearings,dynamic grinding disc, pulley, studio end cover, adjusting shaft, fixed grinding disc, hand wheel, feeding port.The material is crushed in the working room. The material is added from the feed port above the end cover and enters the middle of the two millstones. Due to the crush test, the sample after crushing flows out from the gap between the two millstones and falls into the hopper below.The principle of adjusting mechanism is, normal starting, unscrew and adjust the nut on the handwheel side,unscrew the screw, adjust the handwheel connection shaft forward or backward (small or large grinding plate clearance), to achieve the finness of the required material after locking nut, can only work normally.
C.Precautions for installation and use
Before the test run, it is necessary to check whether the fasteners are tightened, and whether the pulley is flexible by rotating by hand. Abnormal results should be excluded before the test run.When driving, it is inconvenient to make the two grinding disks tight, in case of start-up difficulties.The hardness of the sample shall not exceed medium hardness, otherwise it will affect the grinding property of the grinding disc.It is found that the crushed material can not reach the technical requirements through the adjustment of the adjustment mechanism, then the adjustment of the grinding disc clearance should be considered to adjust the parallelism of the grinding disc. When replacing the sample, in order to make the test data accurate, you can relax the screw, open the end cover, and brush the residual material left in the studio with a brush.
