Complete Guide to Setting Up a 30 TPH Blast Furnace Slag Grinding Plant for 300-Mesh Powder Production

We provide a wide range of mills — including Raymond mill, trapezoidal mill, vertical mill, ultrafine mill, and ball mill, obtained ISO9001 international quality certification, EU CE certification, and Customs Union CU-TR certification. Suitable for processing minerals such as limestone, phosphate, quicklime, kaolin, talc, barite, bentonite, calcium carbonate, dolomite, coal, gypsum, clay, carbon black, slag, cement raw materials, cement clinker, and more.

The discharge range of these mills can be adjusted to meet specific processing needs, typically from 80-400 mesh, 600-3250 mesh, and can achieve the finest particle size of up to 6000 mesh(D50).

Introduction

Setting up a 30 TPH blast furnace slag grinding plant for 300-mesh powder production requires careful planning and selection of the right equipment. Blast furnace slag, a byproduct of iron production, is widely used in cement and concrete industries due to its pozzolanic properties. Grinding it to a fine powder (300 mesh) enhances its reactivity and market value. This guide covers key considerations, from raw material preparation to final product collection, with a focus on optimizing efficiency and sustainability.

Blast furnace slag grinding process

Key Requirements

  • Capacity: 30 TPH
  • Fineness: 300 mesh (D97 ≤ 45 μm)
  • Moisture: ≤5% (pre-drying may be required)
  • Energy Efficiency: ≤30 kWh/t

Equipment Selection

For high-capacity fine powder production, vertical roller mills (VRMs) are ideal due to their lower energy consumption and compact footprint. Our MW Ultrafine Grinding Mill is particularly suited for this application:
