Separation performance of a hydrocyclone with a spiral guide feeding body structure using the response surface method

This study aimed to develop a hydrocyclone with a spiral guide feeding body structure to improve classification efficiency and classification accuracy. The spiral guide feeding body structure could pre-arrange the particles before they entered into the separation chamber, thus avoiding the turbulence of the flow field and effectively improving the separation efficiency and separation accuracy. The flow field features and separation performance of a hydrocyclone were studied using the response surface method to obtain the prediction model of separation efficiency and cut-size and the interaction law between influencing factors and the optimal combination of parameters under multiple response indicators. The industrial application showed that the classification efficiency was improved by 4.56% over the conventional feeding body structure. This indicated that the hydrocyclone with a spiral guide feeding body structure had potential industrial application value and certain advantages in improving the separation performance.
