This article describes a method of grinding a solid mineral material (zeolite), which can be used in medical applications, for the preparation of starting components for biologically active additives. Our method of preparing a solid natural material includes mechanical grinding, ultrasound comminution, and grading of natural zeolite. It differs from previously described methods in that material already ground mechanically to particle sizes of 5 – 20 mm is subjected to comminution and this process continues until particles of 1 – 2 to 10 m are obtained. Zeolite particles obtained after processing in the homogenizer have greater roundness and smaller sizes than those obtained by mechanical crushing. Furthermore, our ultrasound method of comminuting zeolites also reduces the comminution process time by factors of 1.5 – 12.
