Working principle of stone mill grinder
We know that the core components of stone grinding machines include grinding stones, main machines, transmission systems and feeding systems. Its working principle is mainly divided into the following steps.
One is the feeding system. The feeding system includes feeders, belt conveyors and other equipment. The raw materials are input into the grinding machine chamber through the feeding system.
The second is the grinding process. The grinder is equipped with one or more pairs of grinding stones, which are usually composed of natural sandstone, granite or artificially manufactured abrasive stones. These grinding stones rotate and exert a certain amount of pressure, causing the raw materials to be squeezed, rubbed and sheared between the grinding stones. The raw materials are gradually crushed, compressed and sheared under the repeated action of the grinding stones. In this process, the raw materials are ground into fine particles to achieve the grinding effect.
Third, it is the discharging system. After the grinding process, the materials may pass through screening equipment such as vibrating screens. Materials that do not meet product requirements will be conveyed back to the feeding system by the conveyor belt for grinding again. The finished products that meet the requirements will be discharged through the discharge system to form finished powder.
Features and advantages of stone grinding machines
Stone grinding machines have unique features and advantages compared to other grinding equipment.
Start with a gentle grind. The grinding process of the stone mill grinder is relatively gentle and does not generate a lot of heat due to high-speed operation, which helps to maintain the natural flavor and nutrients of the raw materials.
The second is careful dispersion. While the grinding stone is running at high speed, it can grind the raw materials into very fine particles, improving the uniformity and fineness of the product.
Then there is the resistance to thermal damage. Due to the relatively low temperature of the grinding process, the stone mill grinder is not prone to thermal damage to the raw materials during the grinding process, and is especially suitable for some temperature-sensitive raw materials.
Application areas of stone mill grinders
Stone grinding machines are widely used in different fields.
food processing. Used for grinding grains, beans, spices, etc., and preparing flour, condiments, etc.
Cosmetic and pharmaceutical manufacturing. In the production of cosmetics and pharmaceuticals, it is used to grind ingredients to ensure the fineness and uniformity of the product.
Building materials industry. It is used to grind raw materials such as ore and limestone to produce cement and building materials.
Ceramics and glass industry. Used for grinding ceramic raw materials and glass raw materials to ensure the uniformity and fineness of the product.
Maintenance and maintenance of stone mill grinder
In order to ensure the long-term and efficient operation of the stone mill grinder, regular maintenance and upkeep is required.
Lubrication system. Regularly check and replace lubricating oil to maintain the normal operation of the grinding stone.
Grinding stone inspection. Regularly check the wear of the grinding stones and replace excessively worn grinding stones in a timely manner.
transmission system. Check the tightness of the transmission system to ensure stable transmission effect.
Clean up. Regularly clean the debris and dust in the grinder to keep the equipment clean.
Through the above maintenance and maintenance work, the service life of the stone mill grinder can be extended and ensure that it maintains efficient and stable grinding performance in production.
