Description

Technical field:

[0001] The utility model relates to the technical field of calcined coke production, in particular to a calcined coke production system. Background technology:

[0002] High-quality calcined coke: narrow particle size distribution, finished product particle size D10>4.0μm, D50=7.4~7.6μm, D90=13~13.5μm, tap density ≥0.80g / cm3. The production process of high-quality calcined coke is generally roller mill crushing + shaping, and the shaping is continuous shaping or intermittent shaping; the particle size distribution is mainly controlled by roller mill, and the tap density is mainly controlled by shaping; at the current particle size, the tap density processed by conventional shaping equipment is low. If you want to further improve it, there are two measures: first, increase the number of shaping times. As the number of shaping times increases, the tap density increases accordingly; second, use an intermittent shaping machine to increase the shaping time. However, an increase in the number of shaping times or time means a decrease in production capacity, a decrease in yield, and an increase in energy consumption. Utility model content:

[0003] The utility model aims to provide a calcined coke production system with improved tap density.

[0005] Furthermore, an iron remover is provided between the buffer silo and the roller mill, the outlet of the buffer silo is communicated with the inlet of the iron remover, and the outlet of the iron remover is communicated with the inlet of the roller mill.

[0006] The utility model has the following advantages: a horizontal shaft crusher is added before the roller mill to carry out coarse crushing of the calcined coke, which helps to improve the fine grinding efficiency of the roller mill, and a classifier is arranged after the roller mill to classify the product, and the fine powder produced by the fine grinding and the classifier is separated out in time, which reduces the load of the intermittent shaping machine, so that the product entering the intermittent shaping machine can be better shaped, which is beneficial to improve the tap density.
