In grinding wheels, the abrasive particles are bonded together in a matrix. When the wheel rotates, these particles scrape against the marble, removing material and achieving the grinding effect. The size and hardness of the abrasive particles determine the rate of material removal and the fineness of the ground product.
Impact Principle
Impact - based grinding machines, such as impact crushers and some high - speed grinding mills, rely on the impact principle to process marble. In an impact crusher, large marble pieces are fed into the machine. Inside the crusher, the marble is struck by high - speed rotating hammers or plates. The force of these impacts fractures the marble into smaller fragments. The high - velocity impact causes the marble to break along its natural weaknesses and internal stress points.
This principle is very effective for quickly reducing the size of large - sized marble feedstock. In high - speed grinding mills, the impact principle is often combined with other grinding mechanisms. The marble particles are accelerated and then collide with each other or against the inner walls of the grinding chamber, further breaking them down. The intensity of the impact can be adjusted by changing the speed of the rotating components or the design of the impact elements, allowing for control over the particle size of the ground marble.
