Ceramic balls are lighter than steel balls, allowing for higher rotational speeds and thus increasing the grinding efficiency. They also do not contaminate the limestone powder, which is crucial for applications where high purity is required, such as in the pharmaceutical and food - additive industries.The materials used for the inner linings of grinding chambers and the surfaces of grinding wheels have also evolved.
Wear - resistant alloys and composite materials are now employed to withstand the harsh conditions of the grinding process. These materials can resist the abrasion and impact forces exerted by the limestone, ensuring a longer service life of the machine and maintaining consistent grinding performance.
Precision Control and Automation Modern limestone grinding machines are equipped with advanced control systems that enable precise regulation of the grinding process. Automation technology has been integrated into these machines, improving their performance and reducing human error. Variable - frequency drives are commonly used to control the speed of motors in grinding machines.
