china supply Best price of spherical / globular coal tar pitch
pherical asphalt is a kind of high temperature coal tar, which is made from coal tar pitch by heating, dissolving, spraying and cooling forming process. Asphalt is divided into two categories, namely, coal tar pitch and petroleum asphalt. The bituminous binders used in refractories are mainly coal tar pitch. The test material of asphalt adding heating asphalt dissolving dissolving kettle, electric heating coil power supply connected at the same time, the asphalt is ejected from the nozzle, into small particles from air atomization, asphalt particles in the cooling tower with natural air cooling into semi-finished products, by the cooling tower bottom into the three dimension vibration screening filter classification, which was consistent with the spherical asphalt produc
