The invention designs a ball producing process and a ball producing
system in the process of producing inorganic fibers by using
red mud. The process comprises the following steps: firstly, adding materials into a stock bin; secondly, feeding the
red mud, a curing agent, an acidity coefficient modifier and a cosolvent respectively into a crushing mixer according to a
mass ratio; thirdly, feeding the crushed and
mixed materials into a ball press
machine, wherein the tangential pressure of a ball pressing part in the ball press
machine is more than or equal to 2 tons / cm<2>; fourthly, sending ball-shaped materials into a ball bin tank body for curing and
drying in shade. The ball producing
system comprises a dosing
machine, the crushing mixer, the ball press machine and the ball bin tank body, and the devices are connected with one another by a conveyor. The ball producing process disclosed by the invention has the advantages of low cost and high dosing precision, and the process flow is simple and convenient for programmed operation; in addition, the obtained ball-shaped materials have the advantages of low
frangibility and
uniform size, thereby facilitating transportation; when the inorganic fibers are produced, all that is needed is to proportionally mix the
red mud with
coke, the operation is convenient, and the produced inorganic fibers and inorganic
fiber products are stable in quality.
