[0002] The conical mill adopts the principle of continuous and repeated extrusion grinding. The material enters from the top and exits from the bottom. The conical mill has a simple and scientific structure. The material is fed from the top, and the material layer is formed between the roller and the ring cone liner by its own weight and the upper pusher. It is repeatedly crushed by the roller and becomes powder, which is discharged from the discharge port at the bottom of the mill. The roller and the liner are not in direct contact, and the gap is adjustable. The force on the material layer mainly comes from the pressure given by the device and the extrusion force between the materials, thereby avoiding the wear and energy consumption caused by the collision of the grinding media. When the gap between the roller lining, the main shaft speed and the material layer thickness of the conical mill are all adjustable, the product fineness can be adjusted very conveniently and the system can reach the best operating state.

[0003] Among the coffee machines in the prior art, conical grinders are the most suitable choice, considering the different grinding requirements of different coffees. The vertically placed conical grinder relies on the structure that the material enters from the upper end and exits from the lower end. Firstly, it takes up a large space. Secondly, for a coffee machine used on a desktop, considering the size of the equipment, the bean powder channel is also relatively limited. When the coffee beans enter the grinder through the bean bin and are ground into bean powder and then flow out through the bean powder channel, the conical grinder with grinding components arranged above and below is prone to powder jamming, and the coffee powder is not easy to fall into the powder storage tank, which may cause the coffee machine to malfunction in serious cases.
