Product Description:

Spherical asphalt has fixed carbon, Toluene insolubles, High resin content and low ash content, which is widely used in Iron trough castable, gunning in blast furnace, Ramming materials and unshaped refractory castables. Additive carbon material. Spherical asphalt binder can also play a role in increasing carbon, product temperature and resistance to erosion.

Spherical asphalt is made from coal tar pitch which is processed by heating, spraying, cooling and molding. Put the test material asphalt into dissolved kettle for heating and dissolving. At the same time turn on the power electric lap and liquid asphalt is ejected from the nozzle, the air make it atomized into fine particles. Asphalt particles in the cooling tower come into semi-finished products which sent into the three million vibration screening filter from the cooling bottom to get the final spherical asphalt products.

Softening point: 110 ℃,
