The working principle of the stone millstone is based on the combination of traditional mechanical principles and modern technology, mainly involving the grinding and flow of materials. The design of the millstone of the stone mill flour machine takes into account multiple factors to ensure an efficient and high-quality grinding process.
Material grinding process: The surface of the stone millstone usually has regular grooves or lines, which are designed to increase friction so that the material is squeezed and rubbed into powder between the millstones. After entering the millstone, the material needs to be properly stopped and ground to ensure that the required fineness is achieved.
Flow control: The running speed of the millstone, the force between the material and the millstone, and the installation method of the millstone will affect the material flow. For example, the rotation speed of the millstone directly affects the size of the centrifugal force, which in turn affects the flow and grinding effect of the material.
Grinding disc direction: The millstone of the stone mill usually needs to rotate counterclockwise, which is determined by its internal structure to ensure that the material can smoothly enter the grinding center through the guide groove to achieve efficient grinding.
Material selection: Stone millstones are usually made of hard and wear-resistant stones, such as granite or granite. These materials have high hardness, toughness and abrasiveness, ensuring long-term use without wear or breakage.
So the upper half of the millstone, as shown in the figure, the direction of the material is the counterclockwise yellow line, and the direction of the millstone rotation is the clockwise red line, so that the material can pass through the guide trough and enter the grinding center well. If the direction is opposite, it will affect the feeding and efficiency. The millstone we are looking at now is turned over. In actual use, it has to be turned back, so the direction is opposite to the picture, that is, the millstone must rotate counterclockwise for high efficiency. If the direction of the guide trough is opposite to the picture. The millstone must rotate clockwise for high efficiency
