India is the world's second largest producer of cement and produces more than 8 per cent of global capacity. Due to the rapidly growing demand in various sectors such as defense, housing, commercial and industrial construction, government initiative such as smart cities PMAY, cement production in India is expected to touch 550600 million tones per annum (MTPA) by the end of year 2025.

WhatsApp: +86 18203695377Cement ball mills are typically two chamber mills (Figure 2), where the first chamber has larger media with lifting liners installed, providing the coarse grinding stage, whereas, in the second chamber, medium and fine grinding is carried out with smaller media and classifying liners.
WhatsApp: +86 18203695377One potential method is strengthening the internal and external ventilation of the grinder. Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature.
