TECHNICAL FIELD

[0002] In the production of positive electrode material, the sintering process is the core process of the solid phase method for preparing the positive electrode material. At present, the sintering equipment is usually a roller kiln, which is generally provided with an outer rail line matched with the roller kiln. The outer rail line is mainly used to realize the material transportation process of loading into the bowl → shaking and vibrating → material cutting → combination of the bowl → sintering in the roller kiln → separation of the bowl → material crushing → unloading into the bowl, etc.
[0003] The existing method for counting the actual capacity of the roller kiln per day is generally to count the number of the discharged bowl, the weight of the single bowl material and the material loss rate obtained by the laboratory to count the capacity of the sintering process on the same day. For example, the production line personnel count that the single bowl setting loading amount is 8 kg per day, the number of the discharged bowl is 1000, and the experimental loss rate is 28%, so the capacity on the same day is 5760 kg.
