BRIQUETTE MACHINE

A briquette machine 10 is disclosed that equalizes the profile of the thickness and weight of the produced briquettes. The briquette machine 10 includes a hydraulic cylinder 106 that is located at the side opposite a stationary-side bearing unit 56 in relating to a movable-side bearing unit 46 such that the axial direction is along the radial direction of a first roll 12 and a second roll 14. The hydraulic cylinder has a cylinder rod 110 in which one end is provided with a positioning mechanism 120 for adjusting the position of the cylinder rod in the axial direction. The briquette machine 10 also includes a pressure detector 124 that is located between the other end of the cylinder rod 110 and the movable-side bearing unit 46 for detecting the pressure that affects an area therebetween and a controller for controlling an adjustable speed motor 26 such that the number of rotations of a feeder screw 24 is increased or decreased based on the increase or decrease of the detected value of the pressure by the pressure detector 124.
