The invention describes a method for controlling pellet quality in iron ore production, comprising the steps of mixing water, binder and iron ore particles in at least one mixer to form a mixture (step (i)) and pelletizing the mixture into green pellets (step (ii)). Between step (i) and step (ii), a part of the mixture is taken in a sampling operation, formed into a test specimen and subjected to a test. 本发明描述在铁矿石生产中控制球团品质的方法，其包括以下步骤：在至少一个混合器中混合水、粘合剂和铁矿石颗粒以形成混合物(步骤(i))，和将将混合物造球为生球团(步骤(i i))。在步骤(i)和步骤(i i)之间，将一部分混合物在取样操作中取出，成形为测试试样并经历测试。
