KF Series Unpowered Air Powder Classifier

The KF series air classifier utilizes gravity drop and air vortex disturbance to effectively reduce the content of particles smaller than 0.075 mm in the finished sand, achieving linear classification of coarse and fine materials. It is used for the subsequent de-powdering treatment of manufactured sand, producing high-quality sand with stable gradation and adjustable powder content. Compared to traditional heavy-duty classifiers, the KF series air classifier is characterized by its compact size, maintenance-free operation, long service life, and environmentally friendly features.
