The present disclosure provides a burr grinder, which relates to the technical field of grinders and comprises a outer grinder and a grinding core. The grinding core is rotatably matched in the outer grinder; the inner wall of the outer grinder is provided with an inner grinding layer, and the outer wall of the grinding core is provided with a corresponding outer grinding layer; a gap between the inner grinding layer and the outer grinding layer constitutes a grinding channel; the size of the grinding channel is decreased successively from a feeding place to a discharge place, and is successively divided into a crushing region. The burr grinder increases the discharge speed while ensuring the grinding fineness. Moreover, the grinding is smooth and the grinding channel is difficult to cause blockage. The burr grinder has simple structure, low production cost and strong practicality.

An automated coffee machine grinder (1, 25, 30) features two grinding bodies (4) that are rotatable relative to one another about a rotational grinding axis (5) by means of a driveshaft device (10, 31), as well as an outlet opening (2) for ground material arranged laterally of the grinding elements (4). The driveshaft device (10, 31) is positioned divergent from the rotational grinding axis (5). The output opening (2) and the driveshaft device (10, 31) can be positioned differently relative to one another.
