Why is vertical mill better than ball mill in slag powder processing? Slag, also known as granulated blast furnace slag, is a glassy substance that is mostly formed when the slag melted by blast furnace ironmaking is quenched and has no time to crystallize. Its main components are calcium oxide, silicon oxide and aluminum oxide. It has high potential. Activity, under the action of the intensifier, and hydration can generate a cementitious material with hydraulic properties.
Therefore, after the slag is ground into powder, it can be added into cement and concrete products in the same amount. The specific uses are as follows:
1.In cement production, it is directly mixed into cement according to a certain proportion. It is a component material for the production of slag Portland cement to improve the performance of cement and reduce production cost and energy consumption. The addition amount of water slag in slag Portland cement is 20% - 70% by weight.
2.In ready mixed concrete and cement products, equivalent or excessive replacement of some cement can be used as cementitious materials to directly mix concrete and mortar to improve its working performance. Slag powder appears in the construction market as an independent product, which is widely used in concrete and can replace about 50% of cement.
Production test surface, slag powder used in cement and concrete can not only greatly reduce the production cost, but also improve the performance and quality of cement and concrete, which is greatly recognized and welcomed by the building materials market.
In the process of making slag powder from slag, it is inseparable from the participation of pulverizer. In the past, ball mill was widely used in the processing of slag powder, but it was gradually eliminated by the market due to its disadvantages such as high power consumption (when grinding high fineness products of more than 420m2 / kg, the unit power consumption reached more than 85kwh / T), high noise, large wear and tear, etc. The slag vertical grinding system with powerful function and excellent performance has become a new choice for mineral powder processing.
SMMVIK Machinery slag vertical mill integrates crushing, drying, grinding and graded transportation. The system is simple and compact. The floor area is about 50% of the ball milling system, and can be arranged in the open air. Therefore, the investment cost can be greatly reduced. Moreover, the grinding roller directly rolls and grinds the materials on the grinding plate, which has low energy consumption. Compared with the ball milling system, the energy consumption is saved by 30% ~ 40%, and the later operation cost is also reduced.
SMMVIK Machinery can provide a slag processing vertical mill production line with an annual output of 50000-200000 tons. At present, there are many production sites for on-site investigation. You can contact and make an appointment.
