Abstract: Aspects of the present invention relate to an apparatus and a method of determining when a cow may be in oestrus (in-heat), or when the cow is about to calve. The method comprises monitoring movement of the cow using a motion sensor or sensors attached to the cow. The method further comprises determining a mathematical function of the movement pattern of the cow based on the monitored movement of the cow over a period of time, and determining when the cow is in heat or about to calve by analysing and comparing the mathematical function to threshold values which are adjustable by a machine-learning self-adjusting algorithm.

Abstract: A cone crusher including a conical body; a mantle removably positioned over the conical body, and an assembly for securing the mantle on the conical body. The assembly includes a retainer for pressing the mantle onto the conical body, and an adapter located between the retainer and the conical body. The adapter is secured on the conical body and the retainer is movably mounted on the adapter.
