2results about How to "Reduce grinding efficiency" patented technology

This invention discloses a silicon nitride grinding device, relating to the technical field of silicon nitride grinding devices. The device includes a support frame and a collection box. A conical cylinder is fixedly mounted on the upper surface of the support frame, and the collection box is disposed on the lower surface of the support frame. A feed trough is fixedly mounted on the upper surface of the conical cylinder, and a water storage tank is fixedly mounted on the circumferential surface of the conical cylinder. A water spray head is provided on the inner wall of the conical cylinder. A rotating shaft is rotatably mounted on the upper surface of the inner wall of the conical cylinder, and a grinding head is fixedly mounted on the lower surface of the rotating shaft. A grinding disc is fixedly mounted on the inner wall of the conical cylinder. A material unblocking device is also provided inside the conical cylinder. When the feed trough is blocked, it affects the grinding efficiency, potentially causing a decrease in output or production stoppage. Blockage causes material to accumulate in the feed trough, increasing the pressure and stress on the material. If this blockage persists for a long time, it may damage the feed trough.

This application provides a method for finely grinding self-produced coke fines, comprising the following steps: Step S1, coke produced from the coking process is screened at least twice to obtain coke fines; Step S2, the coke fines are finely ground using a ball mill to obtain coke fines slurry; Step S3, the coke fines slurry is fed into a hydrocyclone for classification, and the overflow of the hydrocyclone is a fine-grained slurry; Step S4, the fine-grained slurry is concentrated and filtered to produce fine coke fines. This method can develop a high-quality pulverized coal resource for blast furnace injection systems and can be applied to industrial production, solving the problem of imbalance between the production and consumption of self-produced coke fines in steel companies.
