Slag grinding mills are widely used in India to process granulated blast furnace slag (GBFS) into ground granulated blast furnace slag (GGBFS), a key supplementary cementitious material (SCM) that enhances the durability and sustainability of concrete. Here’s an overview of slag grinding mills in India:
1. Types of Slag Grinding Mills in India
– Vertical Roller Mills (VRM):
– Most common for slag grinding due to high efficiency and lower power consumption.
– Brands: Loesche, Gebr. Pfeiffer, FLSmidth, ThyssenKrupp.
– Ball Mills:
– Traditional but less energy-efficient compared to VRMs.
– Used in older plants or where cost is a constraint.
– Roller Press with Ball Mill (Hybrid Systems):
– Offers better energy efficiency than standalone ball mills.
2. Key Manufacturers & Suppliers
– Loesche India – Supplies VRMs for slag grinding (e.g., JSW Cement, UltraTech).
– FLSmidth – Provides vertical mills for slag and cement grinding.
– Gebr. Pfeiffer – Known for MVR mills used by ACC, Ambuja, etc.
– KHD Humboldt Wedag – Offers roller press solutions.
3. Major Indian Cement Companies Using Slag Grinding
– JSW Cement – Operates multiple slag grinding units near steel plants.
– UltraTech Cement – Uses VRMs for GGBFS production.
– ACC & Ambuja Cements (Adani Group) – Have dedicated slag grinding facilities.
– Dalmia Bharat, Shree Cement, Birla Corporation.jpg)
– Also invest in slag grinding for blended cement.
4. Locations of Slag Grinding Plants
– Near steel hubs like Jamshedpur (Tata Steel), Rourkela (SAIL), Dolvi (JSW Steel), Vizag (RINL), Bhilai.
– Standalone grinding units in states like Odisha, Karnataka, Maharashtra, Tamil Nadu.
5. Market Trends & Drivers
– Growing demand for blended cement (PSC/PPC) due to sustainability norms (BIS standards).
– Government push for low-carbon cement (slag
