In a cement crusher mill, the dust bags typically used are referred to as "filter bags" or "dust collector bags." These bags are part of a dust collection system designed to capture and manage cement dust generated during the crushing and grinding processes. The specific types of dust bags can vary, but they often include:
Polyester Filter Bags: These are commonly used due to their durability and resistance to high temperatures, which are typical in cement mills.
Nomex (Aramid) Filter Bags: Known for their high-temperature resistance (up to 200°C or higher), these bags are suitable for applications with high thermal stresses.
Fiberglass Filter Bags: These are chosen for their excellent temperature tolerance and chemical resistance, making them ideal for challenging conditions.
PPS (Polyphenylene Sulfide) Filter Bags: These are used for their excellent chemical and thermal resistance, particularly in environments where acid and alkali resistance is critical.
The choice of dust bag depends on several factors, including the specific requirements of the cement mill, the temperature, the type of dust being collected, and regulatory environmental standards. Proper maintenance of these dust bags is crucial to ensure efficient dust collection and compliance with environmental regulations.
