Recently, there are a lot of reports about production line replenishment. Generally, it is a small batch to build a large one, and the large part should be supplemented. To determine whether it is big or small, it is calculated according to the cement clinker capacity conversion table in the Implementation Measures for Capacity Replacement of Cement Glass Industry. The Implementation Measures stipulate that the capacity indicators used for replacement shall be determined according to the design capacity on the project filing or approval documents. If the actual capacity is less than registered or approved capacity, it shall be determined according to the actual capacity, and if the actual capacity is greater than registered or approved capacity, it shall be determined according to the registered or approved capacity. The actual production capacity of the project is calculated and determined according to the cement clinker production capacity conversion table in Annex 1.
As a productivity indicator, it is very valuable, and one ton can not be wasted in the replacement process. Therefore, after the reverse calculation of the replacement capacity, there is a capacity scale that is not usually 100 tons per day. For example, there is just a project with a production capacity of 7266 tons per day. Because the kiln diameter is 5.45 meters from the production capacity scale. Therefore, the kiln diameter is not usually 100 mm into the first gear. To put it in a vulgar way, the scale of "pheasant" production capacity and kiln diameter are a little more.
In the practice of capacity replacement, why do we have to haggle over 1 mm and 1 ton per day? It should be the consideration of leaving a way out for the project. If capacity replacement is to be carried out again (although it is still a matter of ten or twenty years later), if the registered capacity is to be compared with the actual capacity, the smaller one will affect the "overall situation".
Recently, there have been cases of additional production capacity. There is a Φ4.8m production line built as early as 2008, with an approved capacity of 4000 tons per day. Most of the early 4000 tons/day production lines fixed the kiln diameter at 4.8 meters. With the development of new dry technology and skilled management and operation, the production capacity of 4.8 meters kiln can reach 5000 tons per day. As a result, the production capacity of 4.8 meters kiln has gradually become 5000 tons per day. It is similar to the situation that the capacity of 4 meters kiln is changed from 2000 tons/day to 2500 tons/day. According to the
original calculation of 4.8 meters kiln, it should be 5000 tons/day, but now it is 4000 tons/day, so it only needs to make up 1000 tons/day. According to the requirement of reduction replacement of 1.5: 1, the production capacity of 1500 tons/day should be replaced from outside. However, there is no such suitable one. If there is, it should also be used as a restricted category. According to the stipulation that the replacement ratio of the production capacity of the restricted cement clinker production line in the national industrial structure adjustment catalogue should not be less than 2:1, the target of 2000 tons per day is required.
At present, there is a 2500 tons/day production line in the province, and the production capacity index is sold according to the reduction ratio. It can replace 1666 tons/day. If only 1500 tons/day are used, the remaining 1000 tons/day will cause subsequent trouble to the transferor. Because according to the current replacement method, the capacity of the cement clinker production line used for replacement can not be transferred more than two projects. It also stipulates that the production line used for capacity replacement must be shut down and dismantled before the construction project is put into operation, and the replacement index project used for splitting shall be calculated according to the time of the first construction project completed and put into operation. That's a lot of "trouble". So eat it all, besides, 5000 tons/day production line to 6000 tons/day is not a "secret" in the industry. From this point of view, it is not inconceivable to reduce the production capacity of 1000 tons per day to 666 tons per day.
However, in case of capacity replacement, the registered capacity of the Φ4.8m production line (according to the current cement clinker capacity conversion table) is 5666 tons/day, and the actual capacity is 5000 tons/day. If you want to replace it, take the smaller one, which can only be 5000 tons per day. Unfortunately, the production capacity index of 666 tons per day can only be watched helplessly!
