The Model 0918 dry ball mill is specifically designed for grinding hard minerals such as ferrosilicon and molybdenum oxide; its technical parameters are optimized to meet requirements for efficient and stable grinding.

The "0918" designation refers to the mill's shell dimensions: a diameter of 900 mm and an effective length of 1800 mm. This specification strikes an optimal balance between grinding efficiency and energy consumption when processing medium-hard materials like ferrosilicon and molybdenum oxide. The shell rotation speed is typically set between 36 and 38 revolutions per minute, ensuring that the grinding media (such as steel balls) are lifted to the appropriate height before cascading down, thereby generating effective impact and grinding action.

Regarding the grinding media charge, the Model 0918 has a maximum capacity of approximately 1.5 tons, with the steel ball grading adjustable based on material hardness and fineness requirements. Feed particle size is generally controlled to below 25 mm, while the discharge particle size ranges from 0.074 mm to 0.4 mm; product separation at various levels of fineness can be achieved by adjusting the classification equipment. The mill is powered by a motor with an output of 18.5 to 22 kW to ensure stable operation.

Utilizing a dry grinding process that requires no water, this model is particularly suitable for regions with water scarcity or for applications with strict limitations on material moisture content. Featuring a simple structure and ease of maintenance, it is widely used in the metallurgy, chemical, and building materials industries, making it an ideal choice for grinding materials such as ferrosilicon and molybdenum oxide.
