[0027] The present invention will be further described below in conjunction with embodiments:
[0028] 1. The ingredients of crushed attapulgite refractory ceramsite are composed of the following components in weight percentage: high-viscosity attapulgite clay powder 5%, attapulgite clay tailings powder 24%, granulated blast furnace slag powder 36%, iron 15% of tailings powder, 12% of coal gangue powder, 6% of bauxite tailings and 2% of diatomite tailings.
[0029] 2. The production method of crushed attapulgite refractory ceramsite: (1) Add the ingredients of the crushed attapulgite refractory ceramsite into a mixer and mix it and then enter the extrusion granulator for granulation. The particle diameter is controlled at 16 mm and the particle length is controlled. In the range of 30-40 mm; (2) The granulated particles are fed into the internal heating rotary kiln for roasting, the roasting temperature is controlled at 800-900℃, and the roasting time is controlled at 5 hours; (3) ...
