Investigation on operating parameters of Raymond Bowl Mill

Traditional Raymond Bowl Mills have been used in the field of grinding for over a hundred years, and the grinding mechanism research is more in-depth, playing an important role in the field of grinding. However, with the depletion of the earth’s mineral resources, the proportion of lean ore and refractory ore is gradually increasing, and the size of the useful minerals is becoming finer and finer. Only sufficient monomer dissociation can be recycled efficiently, so it is necessary to break the Raymond Bowl Mill development and upgrade, the development of advanced grinding equipment to meet the needs of fine grinding.

In order to shorten the technological gap with foreign Raymond Bowl Mill research, domestic Raymond Bowl Mill not only needs to carry out the basic theory research of fine grinding, firstly starts from the technical knowledge of process parameter optimization of Raymond Bowl Mill, and carries out various technical parameters of Raymond Bowl Mill. And the experimental study of the matching of operating parameters provides scientific guidance for the technical research, industrial selection and application of Raymond Bowl Mills.

Parameter inspection

1. The test ore sample is purchased quartz sand. Before the test, the material is crushed into 0.2mm or less, the density of the ore sample is 2.5~2.8g/cm3, and the Mohs hardness is 7.

2. The test condition has a grinding concentration of 45%, a medium addition of 40 kg (filling rate of about 30%), and a grinding time of 10 min.

3. The test process test is carried out according to the steps of mixing, weighing, pulping, timing grinding, grinding product screening and data analysis and processing, and the screening particle size is -120, -200 and -325 mesh respectively.
