  • Rotary Kiln an overview ScienceDirect Topics

    Rotary kilns have been used in various industrial applications (e.g., oil shale retorting, tar sands coking, incineration, cement production, etc.). The rotation of a cylinder-shaped vessel positioned longitudinally approximately 30° of the horizontal position ensures a continuous motion of catalyst between the entrance and exit of the kiln.

  • Cement Kilns: Rotary Coolers

    The largest British rotary cooler, by Vickers Armstrongas installed at Kentand Shoreham, 92' long and 9' in diameter. The design necessitated tall and massive kiln piers, but was easy to maintain and run. Rotary coolers were installed on the vast majority of kilns in the first quarter of the twentieth century.

  • Cement kiln Wikipedia

    01/10/2006· The rotary kiln consists of a tube made from steel plate, and lined with firebrick. The tube slopes slightly (1–4°) and slowly rotates on its axis at between 30 and 250 revolutions per hour. Rawmix is fed in at the upper end, and the rotation of the kiln causes it gradually to move downhill to the other end of the kiln.

  • The cement kiln

    The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.

  • Cement Kilns: Rotary Coolers

    Rotary coolers were installed on the vast majority of kilns in the first quarter of the twentieth century. They were installed either beneath the firing floor, as in the original Hurry & Seaman designs installed by Fellner & Ziegler, or beneath the kiln.The latter design had the advantage that floor space required for the kiln system could be reduced, but meant that the cooler had to pass

    Manufacturing the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the hot end where it eventually drops out and cools
