Attapulgite Powder Vertical Mill
Attapulgite powder vertical mill is the equipment used to grind attapulgite into "rawmix" during the manufacture of cement. It's mainly used in grinding attapulgite and end products in cement plant.
Attapulgite powder vertical mill is made up of feeder part ,discharging part ,rotating part ,transmission part(reducer,samll transmission gear ,motor,electric control) etc. It's a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, ore dressing of ferrous metal and non-ferrous metal, etc. Do your know how does the attapulgite powder vertical mill work in the cement plant? This paper mainly introduces the attapulgite powder vertical mill in cement plant.
In order to achieve the desired setting qualities in the finished product, a quantity (2-8%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement attapulgite powder vertical mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the "specific surface area", which is the total particle surface area of a unit mass of cement. The rate of initial reaction (up to 24 hours) of the cement on addition of water is directly proportional to the specific surface area.
The cement is conveyed by belt or powder pump to a silo for storage. Cement plants normally have sufficient silo space for 1–20 weeks production, depending upon local demand cycles. The cement is delivered to end-users either in bags or as bulk powder blown from a pressure vehicle into the customer's silo. In industrial countries, 80% or more of cement is delivered in bulk.
- Large application range, simple structure and convenient maintenance;
- Installation and adjustment are very convenient and easy to be operated;
- Large capacity and continuous work are very obvious;
- Barrel lining and grinding media can apply various abrasive materials;
