Abstract
857,818. Preheating and charging granular materials. POLYSIUS G.m.b.H. Aug. 18, 1959, No. 28247/59. Class 51 (2). In apparatus for preheating and charging cement raw materials of the type comprising serially interconnected cyclone separators through which the material passes generally in counterflow to hot kiln gases, the centre lines of the cyclone separators 2, 3, 4 and 5 are inclined at approximately 45 degrees to the vertical forming a zig-zag, Fig. 2 (not shown), and the exhaust gas pipes 6a, 6b, 6c between cyclones are straight. The last exhaust gas pipe 6d leads to a fan or a filter, and raw material enters the system through a pipe 7d. The exhaust dust pipes 7, 7a, 7b and 7c are approximately at right angles to the exhaust gas pipes, pipe 7 forming a short feeding preheated material into the kiln 1. The exhaust dust pipes leave the bottom of their respective cyclones as wide, radial, tapering pipes narrowing to enter the exhaust gas pipes, Fig. 3 (not shown). Alternatively, Fig. 4 (not shown), each dust exhaust pipe may leave its cyclone tangentially. The diameter of the cyclones may decrease upwardly.
