Abstract

PURPOSE: To briquette pulverized coal into the shape of a regular hexahedron, by a method wherein pulverized coking coal is supplied to an open-top briquetting mold composed of two side rollers, two side plates and a bottom plate, and compacted from upper side by means of a roller to form a thin film, and this operation is repeated.
CONSTITUTION: A briquetting mold is composed of two side rollers 1,2, two side plates and a bottom plate 5 which is movable downwards and supported horizontally by means of a cylinder 6. Said rollers 1,2 are spaced away from each other by a gap B, and arranged in parallel. Said side plates are spaced away from each other by a gap L, and vertically arranged at both sides of said rollers and along the length of said rollers. Pulverized coking coal 10 is supplied from a hopper 8 to said briquetting mold in a definite height. The supplied coal 10 is compacted from above by rolling a main roller to form a band having a thickness of h, a width of B and a length of L. Then the bottom plate 5 is made to descend by h in height. At the same time, the side rollers 1, 2 are rotated to compact the both ends of the band. Then the pulverized coal 10 is supplied onto the band in a definite height, the coal is compacted by the main roller and the bottom plate is lowered. This stage is repeated H/h times to obtain a regular hexahedral compacted product having a thickness of H, a width of B and a length of L.
