を提供することを目的とする。2. Description of the Related Art Conventionally, in the briquette machine as described above, it is easy to supply the powder or granular material between the rotating rolls, and in the low pressure briquette machine, the gravity dropping method is used. For powders and high-pressure briquette machines that are difficult to achieve, a method of forcedly feeding by using a screw is generally used as disclosed in Japanese Utility Model Publication No. 2-1595. However, when the powdery or granular material is forcibly supplied by using the screw, the screw is rotated to make a circular motion, and therefore the screw or powdery material is located at both ends of the width of the roll. Since the effect of the above is hardly reached, the raw material could not be sufficiently pushed and supplied in this part, and the granulated briquette was inhomogeneous over the entire roll width, and low quality briquette was produced at both ends of the roll. It will be grained. The present invention has been made in view of the above problems, and an object of the present invention is to provide a briquette machine capable of uniformly supplying a powdery or granular material over the entire width of a rotary roll.

１．１により加圧造粒された。The above-mentioned structure has a rotary roll 1.1 pressure (maximum) 150 t (140 to 130 t during operation), a rotary roll diameter of 520 mm, a roll width of 284 mm, and a roll pocket size of 28.5 mm. × 20mm × 5.6mm × 9 rows, high speed rotary projection rotor 5 diameter 400mm, throwing blade width 280mm,
Rotation speed 1450r. p. m and a projection speed of 30 m / sec. Using this device, lime powder was supplied to the high-speed rotation projection rotor 5 by the screw conveyor 6 in an amount of 6 ton / hr. The supplied lime powder is scooped by the throwing blades 4.4 of the high-speed rotation projection rotor 5 to rotate at high speed, and is given a sufficient speed to rotate from the cut portion of the guide 7 to the rotation roll 1 as indicated by an arrow. No. 1 was sequentially projected toward the intermeshing portion and uniformly supplied and adhered over the entire width of the roll, and granulated under pressure by the rotary roll 1.1.

It was confirmed that a homogeneous granulated product was obtained over the entire roll width. On the other hand, under the same conditions, when a conventional method of supplying lime powder with a screw was used without using a high-speed rotating projection rotor, the granulation in the central 5 rows of roll 1.1 was crushing strength. The granulated product in each of two rows of 25 to 20 kg rolls had a crushing strength of 18 to 12 kg.
