The open circuit grinding process is the earliest slag powder grinding technology. It has the advantages of simple process, low technical requirements for operators, and low investment ...
Why choose vertical mill for slag grinding ? Energysaving, environment friendly, simple process, high intelligences. Nowadays, the slag vertical roller mills are widely accepted by customers, but some customers may still doubt about the vertical roller mill and ball mill. By doing research in more than 10 factorys of customers, we have summed ...
of the grinding material is poor; (4) The system power consumption is 80kwh/t, and the roller press system has a large circulation amount, and it has to be transported by the belt conveyor and the lifting conveyor, so the system is dusty; (5) System operation rate: 85%90% Vertical mill process features: (1) The structure is simple, the vertical mill installation is adopted, the floor space is ...

Steel slag ball mill is the key equipment of steel slag processing production line. The steel slag ball mill is different from other ball mills. It is a special steel slag grinding equipment ...
The length of the first bin can be shortened to and the second increased to to enhance the grinding capacity of the ball mill. Secondly, transform the partition board to 2mm, so that the slag can be well broken in the first bin and the slag with particle size <2mm enters the second bin for grinding.

(granulated blast furnace slag, fly ash, pozzolanes, limestone etc.). The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press.
1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

The difference between ball mill and vertical mill in cement grinding Over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.
Ball mill: 38kWh/t. HPGR plus ball mill: 3034kWh/t. VRM: 2832kWh/t. Grinding is a very energy intensive process that accounts for a significant amount of production costs. 7 This is why advances in classifier technology have been vital in increasing production efficiency. Since GBS and pozzolan require a large surface area for reactivity, the ...
