What is the inclination angle of the spiral classifier machine groove?
The structure of the spiral classifier itself has three main factors that will affect its classification efficiency: the inclination angle of the spiral classifier machine groove, the height of the overflow weir and the spiral speed.
The inclination angle of the machine groove of the classifier affects the settlement area of the classifier, but since the machine groove of the spiral classifier is fixed after installation, the inclination angle of the machine groove of the classifier needs to be adjusted to an appropriate angle during installation. Generally speaking, it is advisable to install the classifier with an inclination angle between 16-18°.
If the inclination angle is too large, the subsidence area will decrease, the coarse-grained material will easily slide down, and the overflow particle size will become coarser, but the fine-grained material in the returned sand will also decrease correspondingly; Medium and fine-grained materials will also increase. Therefore, when designing the dressing plant, it is necessary to comprehensively determine the size of the inclination angle according to the nature of the material, the fineness of the classification and other factors.
