Details and application of mineral sizers At present, the commonly used mineral sizers module particle size has roughly the following two adjustment modes: 1) Adopt eccentric ring to adjust the roller spacing, the adjustment range is less than 40mm. Advantages: The adjustment is simple and the workload is small. Disadvantages: the center distance and center height of crushing roller will be changed after adjustment. Therefore, the transmission part needs to be adjusted greatly. The adjustment mode is mainly used for through crusher.

When mineral sizers are used in the open pits in the cold area, it is common to see the broken material sticking to the roller, especially in winter. The material makes the rollers sticky, the tooth tip can not be exposed, so that the tooth roller can not complete the hammer operation, becoming the smooth roller, the material can not be broken. So that the upper conveying mechanism material accumulation, it can only stop for cleaning. Cleaning labor is intensity and waste time, greatly affect the work efficiency. The phenomenon of parking cleaning should be carried out several times a day, so

The vibration of mineral sizers affects the stability of crusher operation, so their vibration problems must be investigated. Firstly, the theoretical model of the crushing roll was established based on the common rigid disc model, elastic shaft model and elastic support model in the rotor system; and the equations of motion were obtained. Secondly, the finite element model was established in ANSYS and the modal analysis was carried out to verify the correctness of the finite element model by comparing the modal analysis results with the analytical solution. Finally, based on the operating con

Roller teeth are the key parts of mineral sizers, and the damage of roller teeth is the most serious. Using the finite element method to simulate the stuck-turn phenomenon and analyze the strength of the roller teeth, the results show that this strength design can provide a reference.

Apron feeders is an important equipment for mining, metallurgy, port and chemical industry. For a long time, there is no unified and systematic theory for calculating the shear resistance at the feed opening and the frictional resistance between the material and the skirt plate in professional manuals, and some even contradict each other. The traction theory of plate feeders applied to inclined skirts has not been studied. A series of analytical solutions for the drag calculation are derived starting from the establishment of differential equations. This theory is of great importance for the d

In order to ensure the safety of personnel and production needs, a regulating wall is built in the mine and a regulating window is opened in the belt conveyor cover. According to the needs of mine transportation and ventilation, part of the transport belt has to pass through the regulating wall. When the wind flow passes through the belt hole of the regulating wall, the wind speed through the belt hole will become bigger because the ventilation section suddenly becomes smaller. During the experiment, the utility modeler found that if the hard wind shield was used, the coal on the belt conveyor

Why should I use a Mineral Sizer over a Jaw Crusher, Gyratory Crusher or Impactor? A Mineral Sizer offers a more effective means for crushing clay-ridden sticky material, eliminating the need for recirculation of oversized material as produced by Jaws, Gyratories or Impactors. Mineral Sizers have a lower capital cost than other primary crushers as well as a lower infrastructure/structural cost.
