Method for producing cold compression blocks

A method for producing cold compression blocks includes the steps that mill scale is naturally dried in the sun; raw materials comprise, by weight ratio, 53% of scale, 31% of extracting vanadium fly ash and 16% of blast furnace fly ash, and binder is added for the first time; the raw materials are mixed in a kollergang, and the binder is added for the second time during mixing and crushing; the binder is added for the third time after the raw materials are evenly mixed and crushed and discharging is performed; the raw materials are machined to balls through a ball press machine; and the ball-shaped cold compression blocks are roasted at a chain grate to obtain finished products. The binder is added for three times and in batches to prevent higher temperature in the kollergang from damagingcomponents of the binder, the mixing of materials and the binder can be effectively guaranteed, and water in the binder can help dissolve CaO of the raw materials and can effectively improve the binding effect between the ma
