PRESSING AND BRIQUETTING DEVICE Russian patent published in 2023 - IPC B30B11/24 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in devices for producing briquettes. A shaft with an auger is placed in the body of the device. A pressing unit in form of a die formed by cylinders of various lengths is detachably connected to the body. The cylinders are made with stacked sets of elliptical through holes, which have different lengths and cross-sectional areas. Cylinders are arranged in steps and with offsets relative to the axis of the shaft to ensure breakage of the obtained briquettes of a certain length under the action of a bending moment arising from the gravity of the briquette, and their fall into the corresponding zone of accumulation of briquettes.

EFFECT: need to use a cutting device is eliminated, which leads to a reduction in energy costs, a simplification of the design of the device and an increase in the reliability of its operation.
