Impact - based grinding machines, such as impact crushers and certain high - speed grinding mills, rely on the impact principle to process talc. In an impact crusher, large talc pieces are fed into the machine. Inside, the talc is struck by high - speed rotating hammers or plates. The force of these impacts fractures the talc into smaller fragments. The high - velocity impacts cause the talc to break along its internal weaknesses,
effectively reducing its size. In high - speed grinding mills, the impact principle is often combined with other grinding mechanisms. Talc particles are accelerated and then collide with each other or against the inner walls of the grinding chamber, further breaking them down. By adjusting the speed of the rotating components or the design of the impact elements, operators can control the intensity of the impact and the resulting particle size of the talcum powder.

Some talcum powder grinding machines, like roller mills, utilize the shearing principle. In a roller mill, two or more rollers rotate in opposite directions. The talc is fed between these rollers, and as they rotate, a shearing force is applied to the talc. This shearing action splits and crushes the talc particles.
The gap between the rollers can be adjusted to control the particle size of the ground talcum powder. A smaller gap results in a more intense shearing action, producing finer - sized particles, while a larger gap yields coarser particles. The shearing principle is effective for talc as it can break the mineral along its internal planes of weakness, facilitating efficient grinding.
