A production line is a factory configuration that features a series of manufacturing steps. Items flow from step-to-step moving closer to becoming a finished product, part or component with each step. Batch Production vs Mass Production Production lines are used both in batch production and mass production.
The main equipment used in the production line is the jig machine, and a single machine capacity is about 100~120 tons per hour. Its feeding size ranges from 5 to 50mm in different beneficiation systems. It's widely used in metal or non-metal gravity separation, such as fluorite, barite, gold ore, iron ore, manganese ore, etc. FEATURES
