Features and development direction of air classifier ALPA

Airflow classifier is a kind of equipment that uses centrifugal force of impeller rotation and drag force generated by airflow to classify materials. It is widely used in the classification and purification process of quartz, feldspar, mica, kaolin, and magnesium oxide. It has the characteristics of high classification accuracy, energy saving and high However, this difference is negligible and does not change significantly in different configurations. The narrow body with the diameter D1 is the same in both the separator and the classifier cyclone. The main resistance occurs in this region. In the virtual body containing the racks, the resistance increases slightly due to the racks.Investigation into the effects of various parameters on the

Experimental investigation of energy efficiency of an air classifier

A pilot-scale air classifier mill was utilized to evaluate the influence of impact velocity, number of hammers, and air mass flow rate on the grinding performance. By measuring the input torque and speed, the input energy of the grinding process was obtained and used to quantitatively investigate the no-load power consumption, total An approach to quantifying the impact grinding performance of dif ferent materials is presented. Based on a dimensional analysis and on fracture mechanical considerations, two material parameters, fMat. and Wm,min, are derived theoretically. fMat . characterises the resistance of particulate material against fracture during impact comminution.
