摘要： PROBLEM TO BE SOLVED: To prevent the generation of deposition of a wet material to be supplied in a raw material transporting apparatus by introducing a hot gas into the raw material transporting apparatus and mixing the dry tailing which comes out of a wind sorting apparatus, with the wet raw material to be supplied in the raw material transporting apparatus. SOLUTION: In a roll mill in which a wind sorting apparatus 4 is installed above a lower part mill part 3 provided with a rotatable crushing stand 7 and a crushing roll 8, to dry and crush a wet material 13 such as wet cement, the material 13 is transported to the crushing stand 7 through a raw material- introducing path 12 and crushed in the stand. At least a part of the crushed material is sent to the wind sorting apparatus 4 with the ascending current of a heated gas and dried, and rough particle of the material is turned back to the crushing stand 7 as the tailing. In this case, in order to carry out preheating of the material 13 in the introducing path 12, the heated gas is introduced into the introducing path 12 and the material 13 is mixed with the tailing coming out of the sorting apparatus 4 in the introducing path 12 and then the resultant mixture is supplied to the crushing stand 7.

摘要： PROBLEM TO BE SOLVED: To prevent pulverized matter from being stuck by temperature rise of the upper surface of a rotary table to stably pulverize petroleum pitch with respect to a vertical roller mill for pulverizing petroleum pitch, coal and the like. SOLUTION: There is a rotary table 12 in a lower chamber 7 of a mill casing 8, and petroleum pitch raw material 1 is fed from above onto the upper surface of the table 12 and gets biting in a roller 4 to turn it into pulverized matter 5, which is blown up from below by hot air 6 and is sent to a classifier. Since the upper surface of the table 12 is made a surface having gentle curvature continuously from the outer peripheral part thereof and furthermore, heat insulating material 9 made of plastic is fitted on the lower surface and the outer peripheral end surface of the table 12, temperature rise of the upper surface of the table 12 by hot air is restrained (to keep the temperature of the upper surface at

摘要： PROBLEM TO BE SOLVED: To provide a crusher having improved crushing efficiency. SOLUTION: In a crusher having a plurality of rollers 11 disposed on the peripheral surface of a rotational table 4 to crush raw material between the rollers 11 and the table 4, a scraper is located upstream of each of the rollers 11 and one end of each scraper is axially supported on a casing 3 so as to be rotatable along the peripheral edge of the table 4, and a rotating means for the scraper is disposed between the scraper and the casing 3 so that the scraper can rotate within the width of the roller 11.

摘要： PURPOSE: To effectively crush substances different in particle size by adjusting fluid supply flow by a reinforcing cover member in the vicinity of a blade ring and moving crushed material particle flow by a flow envelope. CONSTITUTION: A crushing roll 7 is rotated on a crushing surface 5 in the vicinity of the crushing pan 6 of an air streamer type mill 4 being a crusher. A material to be crushed is supplied to the central part of the crushing pan 6. An annular space 8 is formed between the crushing pan 6 and a wall surface 3 and a blade ring 12 is arranged to the annular space 8 and blades are tangentially set to a predetermined angle α and an annular gas guide mechanism 14 is formed. Further, liquid supply flow 1 is discharged by the action of the flow channel 15 of the annular gas guide mechanism 14 and a reinforcing cover member 10 is arranged to the upper part of the blade ring 12. Crushed material particles are involved in fluid supply flow 13 to form a flow envelope and this space arranging structure or a vertical extension line is adjusted by the liquid supply flow 13.
