Product Details

Introduction

GGBS grinding Plant refers to a complete production line that uses Granulated Blast Furnace Slag (GGBS) as raw material and processes it into high-fineness slag micro-powder through grinding technology. The GGBS grinding line is an important supporting process in the cement and concrete industries, aiming to convert blast furnace slag into high-performance admixtures, enhance the durability of concrete and reduce carbon emissions.

Process Flow

1.Raw material pretreatmen

Cooling and crushing: High-temperature liquid blast furnace slag is quenched in water and cooled to form granular slag (with a particle size of approximately 5 to 20mm), which is then roughly crushed by jaw crushers and cone crushers.

Iron removal and screening: Magnetic separators are used to remove metal iron impurities, and vibrating screens are used for classification to ensure the uniformity of particles.

2.Grinding and classification

Grinding equipment:The vertical mill is characterized by high efficiency and energy conservation, and is suitable for large-scale continuous production.Ball mills are suitable for small-scale applications or scenarios with extremely high requirements for product fineness

Grading system:The fineness of the finished product is controlled by an air flow classifier (specific surface area ≥400㎡/kg, usually 420-500㎡/kg is required). The substandard particles are returned to the grinding chamber for recycling treatment.

3.Dust removal

Equipped with pulse bag dust collectors and wet dust removal systems, the dust emission concentration is ≤10mg/m³ (conforming to the GB 4915-2013 standard).

4.Finished product storage and packaging

The finished slag micro-powder is pneumatically conveyed to the silo for moisture-proof storage.

The packaging specifications are bulk (for direct use in cement plants) or bagged (50kg/ bag).

Production Line

Colombian Client’s Daily Production Line of 200 Tons Gypsum Powder Grinding

The gypsum grinding and calcining production line of Colombian customers was put into production in March 2017. It is mainly used for processing gypsum with raw material size less than 30mm and finished products with fineness of 200-500 mesh.

Bolivia Customer’s Mill Production Line of Glass Crushing Powder

Bolivian customers' glass crushing and grinding production line is mainly used for waste glass crushing and grinding, etc.
