Slag is also known as granulated blast furnace slag, it is a by-product of blast furnace iron-making and has high potential activity and hydraulic properties. Its main purpose is to directly incorporate cement in a certain proportion in cement production, and is a component of slag Portland cement production. Materials to improve the performance of cement and reduce production costs and energy consumption. The amount of water slag added to the slag Portland cement is 20% to 70% by weight; equivalent replacement or excess substitution in ready-mixed concrete and cement products. Some cements are used as cementitious materials to directly mix concrete and mortar to improve their working performance. As a separate product, slag powder appears in the construction market and is widely used in concrete. It can replace about 50% of cement.

Slag powder production process equipment

The current slag ultra-fine powder preparation is mainly based on vertical roller grinding mill. The characteristics of slag vertical mill system produced by chaeng , the materials are suspended in the inside of the mill and the cycle of coarse powder is repeated. The heat exchange is fully efficient and the power consumption is low. The grinding, powder selection, and drying are completed in the mill at the same time. Simple, fine and easy to adjust, the stability of the material bed to prevent vibration. The ball mill system has a simple process system and is easy to operate. However, the system has low efficiency, high power consumption, high finished product temperature, and inconvenience in adjustment of finished product fineness.
