Since the cost of limonite ore crushing and grinding account for a large proportion of the total limonite ore processing cost, it is of great importance for mine owners to choose a trusted mining equipment machine brand and high-quality and suitable limonite ore crushing machine.
2, in order to make the 10 mm under sieve , in the case of coal with HGI of 50 (hard and poor quality), the peripheral speed of the hammer 4 It is understood that it is sufficient to set the HGI to 100 m / s or more, and in the case of coal with HGI of 100 (soft and good quality), the peripheral speed of the hammer 4 should be set to 18 m / s or more. 3, in the case of coal with HGI 50, the peripheral speed of the hammer 4 may be set to 68 m / s, and the HGI is 100 (soft and good quality).For example, in the case where the upper gap W 1 and the lower gap W 2 are 20 mm from FIG. Further, in order to increase the 0.3 mm sieve by 10% from FIG. ), It can be seen that the peripheral speed of the hammer 4 should be 15 m / s.

While developing the testing method, the authors tried to make the greatest possible use of the determined parameters, independent of the subjective feelings of the personnel. Therefore, the efficiency of production and the results of chemical analyses conducted by external bodies to assess the quality of the excavated coal material were verified using the registration results of the machines’ diagnostic parameters and surveying measurements.The application of industrial automation systems has allowed for a very objective and reliable assessment of the utilisation rate of these machines. Such an approach to the issue of the analysis of machine effectiveness made it possible, at that stage, to assess the machines in a very objective manner.
As shown in Table 9, the unit weight of each fresh mixture ranged from 1994 to 2324 kg/m3, which is within the range of normal CLSM reported by ACI Committee 229 .Table 9 presents the fresh unit weight of the different tested mixtures. Among them, the M15 mix had the smallest unit weight (1994 kg/m3), and the M1 mix had the highest unit weight (2324 kg/m3). This fill can be applied to reduce the load on buried structures and underlying soils or fills. The low unit weight mixtures may be used as a lightweight fill.
By comparing the power (torque) curves at the same speed, the growth trend of the experimental curves is consistent with the results of the theoretical analysis and simulation curves.The theoretical and simulation results are verified by experiments.
