Slag Dryer for Portland slag cement Production

04-24-2023 Hits：

Portland slag cement is abbreviated as slag cement. It consists of Portland clinker, 20% - 70% granulated blast furnace slag and appropriate gypsum. Before to use slag for Portland slag cement Production, the Water-cooled blast furnace slag is wet, and need to dry and get rid of the water in advance, then rotary slag dryer machine is one necessary equipment.

Application of Portland Slag Cement:

Used in ordinary concrete, various high-grade, high-performance concrete, and cement products to replace cement in equal quantities, in order to improve the durability of concrete and cement products in various harsh environments. The addition of ultrafine powder such as slag enhances the compactness of concrete and cement products, resulting in high later strength and reduced costs of concrete and cement products.

1. It is used in industries such as high-strength, ultra-high strength, high-performance concrete, prefabricated pre mixed poles, pipes, and large bridges, with high strength and smooth surface.

2. Used in marine engineering, dock, reservoir, and tunnel engineering that are subject to seawater erosion.

3. Used for basic engineering in various environments.

4. Used in highways, airport runways, heavy-duty vehicle road engineering, etc.

Before to use the slag to produce ortland slag cement, firstly needs to dry and get rid of the water, then grind the dry slag into powder accordingly. Slag is also kown as Water-cooled blast furnace slag which is by product of Blast furnace iron making plant， and it is wet, and its moisture content varies from 15%-20%. Obviously, it is too wet to be processed and grinded into powder.

Then, Rotary Slag Dryer is the ideal drying equiment for dewatering the wet slag. Slag Dryer also is called slag drying machine, and it is developed from rotary drum dryer.

Slag Dryer, Slag Drying Machine, Rotary Slag Dryer, Slag Drying System,

Slag Dryer Machine is to use high temperature flue gas to heat and dry the wet slag quickly and continuously, and usually there is burner and hot air furnace to burn the fuel to creat the hot air for the slag drying system.

For one unit of slag drying system, except the key drying equipment slag dryer, the other related machines mainly are mechanical feeding hopper, input belt conveyor, output belt conveyor, cyclone separator, induced fan, pulse bag filter, chimney, etc.
