s1, raw material processing, namely, throwing natural magnesite into the interior of a crusher (1) through a feeding hopper (2), crushing the natural magnesite through two crushing toothed shafts (3), leading the crushed natural magnesite into the interior of a connecting hopper (5) through a discharging hopper (4), then sending the crushed natural magnesite into the interior of a mixing tank (8) through a first feeding machine (6), leading an air blower (18) to work during crushing, leading air to be sucked into the interior of a filter (16) through an air suction pipe (21), leading wind power to enter the interior of a dust suction pipe (23) through a collecting tank (15), sucking floaters generated during crushing of the crusher (1) through a horn cover (26), leading the sucked floaters to enter the interior of the collecting tank (15), being filtered by a dust filter bag (24) and a filter screen (25), and being intercepted in the interior of the collecting tank (15), so as to effectively collect the floaters, after the device is used for a certain time, the collected waste is discharged through the discharging pipe (19) only by opening the sealing cover (20);
s2, mixing and stirring, after the crushed materials enter the mixing tank (8), people add external materials in the mixing tank (8), start the mixing motor (9) to work, the mixing motor (9) drives the stirring shaft (27) to rotate, the stirring shaft (27) drives the stirring paddle (28) to rotate, so that the added materials are stirred and mixed, the stirring shaft (27) drives the driving gear (33) to rotate while rotating, the driving gear (33) drives the driven gear (34) to rotate, the driven gear (34) drives the rotating shaft (30) to rotate through the shaft seat (31), the rotating shaft (30) drives the spiral blade (32) to rotate, the materials can be conveyed to the inside of the second feeder (11), and the phenomenon that the materials are blocked in the discharging pipe (10) can be avoided;
and S3, sintering, namely feeding the material into the shaft kiln (13) through the second feeding machine (11), and sintering through the shaft kiln (13).
