TH26331C3 - The grinder is fine powder and the method of grinding it into fine powder. - Google Patents

Abstract

DC60 (22/09/42) a fine powder grinding machine (10) has been revealed, consisting of a fan (12) which draws air through a duct (28), a feed hopper (42) receives the material, which is then milled to Fine powder, the feed hopper (42) has an open bottom end that contacts the pipe (28). Between the feed hopper (42) and the fan (12) there is an isthmus (36). The air flows through the isthmus (36) at a speed of 1 Mach or More fragile fragments that fall into the feeder hopper (42) are sucked into the isthmus (36), where the material is obtained. By blowing apart and reducing its size to powder, a fine powder mill (10) has been revealed, consisting of a fan (12), which draws air through a duct (28). The feed hopper (42) receives the material, which is then cooled. Grinded into fine powder, the feed hopper (42) has an open bottom end that contacts the pipe (28). Between the feed hopper (42) and the fan (12) there is an isthmus (36) .Air flows through the isthmus (36) at speed 1. Mach or rather fragile material dropped into the feed hopper (42) will be sucked into the isthmus (36), where the material will be Blowing apart and reducing its size to powder

Claims (9)

1. A pulverizer is a fine powder consisting of air-flow ducts (28) including isthmus (36), air drive devices (12) for inducing air flow through the isthmus. Such at a speed Mach 1 or faster and the channel enters There is also an air duct at the isthmus flow origin where fragments of fragile material (SP) can be fed into the Such air ducts Such an air drive device that has an inlet (30) of that device connected to the The output of the isthmus. 2. The grinder is a fine powder, as has the right in Clause 1, with the characteristics of which the air drive device. As a fan swinging from the center With the suction inlet (30) of it is in the same axis as The fan spinner of the device and its outlet (32) are in the direction of the fan spindle. 3. The grinder is a fine powder as it holds the right in Clause 1, with its characteristics. Which is the isthmus It is composed of the neck portion (54), the convergence part (52), which has a reduced area from the end of its air intake to the throat. It and the detach (56), which increases the area from the throat to the end of its air intake. 4. The grinder is a fine powder, as it holds the right to claim 3, with its characteristics in which the aforementioned sections (52, 56) have both circular sections. 5. The grinders are fine powder, as claimed in claim 1, and include a separate sieving device (64) where the material is ground to a fine powder to prevent chipping. Which is larger than the specified size To the isthmus 6.The mill is a fine powder as claimed in Clause 1 and includes equipment for feeding the scraps. Such a solid piece is a stream of scrap. Which have been spaced from each other in the direction in which they are moving 7.The grinder is a fine powder, as claimed in Clause 6, where the equipment consists of Slanted-type swivel-feed screw (62) for lifting debris that pass through the screen, which prevents debris larger than a specified size from entering the feed screw. The debris has been drained. From the top end of the feed screw to fall into the duct. 8. The grinding method is a fine powder of a fragile material (SP) in which air is drawn through the isthmus (36) at a speed equal to or greater than 1 bundle, and the fraction of the material being ground to a fine powder is taken. To air at Is flowing to the isthmus to be carried to the isthmus by flowing air. 9. The pulverizer is a fine powder as claimed in Clause 8 and consists of separating pieces of The material (SP) goes out into the scrap stream. Which will reach the isthmus, respectively 1 0. The mill is a fine powder, as entitled in Clause 9, and consists of separating the said material to prevent debris larger than a predetermined size to reach the isthmus. have
