Working Principles of Lignite Grinding Machines
Lignite grinding machines operate based on several fundamental principles that enable the transformation of large lignite chunks into fine powders. Understanding these principles is crucial for optimizing the performance of the machines and ensuring efficient lignite processing.
Impact Principle
The impact principle is widely utilized in many lignite grinding machines, such as impact crushers and some high - speed grinding mills. In an impact crusher, large lignite pieces are fed into the machine. Inside, the lignite is struck by high - speed rotating hammers or plates. The force of these impacts fractures the lignite into smaller fragments. The high - velocity impacts cause the lignite to break along its internal weaknesses and natural cleavage planes.
This principle is very effective for the initial size reduction of large - sized lignite feedstock. In high - speed grinding mills, the impact principle is often combined with other grinding mechanisms. The lignite 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 ground lignite.
