Background

After the iron ore concentrate or the iron-containing powder and the additive are pelletized on a pelletizing machine to generate qualified green pellets, the qualified green pellets automatically fall onto a transfer belt, the green pellets are transferred to drying and roasting equipment by a belt conveyer, the green pellets fall and collide for many times in the process of transferring the green pellets, if the falling strength of the green pellets does not meet the production standard, the green pellets are cracked or crushed before drying and roasting, so that a large number of cracks are generated after roasting the green pellets or a large number of powder is generated in the roasting process, the process operation of the green pellet roasting equipment is seriously damaged, various accidents are induced, the operation rate, the yield and the quality index of products are seriously influenced, and the operation and the smooth operation of a blast furnace are damaged.

In the existing pellet falling strength detection process, no special detection equipment is provided, so that production personnel often fall from a certain height according to subjective consciousness and repeatedly perform the process until green pellets crack, and the falling frequency is recorded. The subjective factors of the green pellet detection process are too many, so that the falling strength of the pellet is inaccurate, necessary technical support is difficult to provide for actual production, and after the green pellet falls onto the steel plate and is broken, if the green pellet does not fall into the steel plate in time or residual broken pellet powder on the steel plate is not cleaned, the impact force of the green pellet and the steel plate is reduced if the falling green pellet falls onto the broken pellet powder next time, and the green pellet detection accuracy is also influenced. Therefore, in order to solve the above problems, we propose a ball drop strength detection device.
