Description

Technical Field

[0001] This utility model relates to the technical field of bone particle sorting and pulverizing machines, specifically to a bone particle sorting and pulverizing device. Background Technology

[0002] Bone grains, also known as skeletal grains, biological grains, or fossil grains, are a type of heterogeneous grain found in carbonate rocks, composed of hard remains secreted by organisms. Rich in nutrients such as phosphorus and calcium, bone grains have numerous applications in agriculture, industry, and even the food sector.

[0003] Bone particles are usually crushed into bone chips during processing using a crushing and sorting machine. However, current crushing and sorting machines for bone particle crushing have the following drawbacks: the amount of bone particles fed into the crushing chamber from the feed inlet cannot be well controlled. If all the particles are fed in at once, it will cause incomplete crushing and large differences in particle size. At the same time, since a lot of dust often remains inside the machine after crushing, there is a risk to the health of operators if the dust cannot be controlled. Utility Model Content
