The reformed crusher has been used in Bayangol Coal Preparation Plant for 12 months and has been running smoothly without any production and safety problems. It has high reliability and safety; Low crushing rate and the discharge particle size is adjustable, the product size is controlled below 50mm, the product structure composition is optimized, and the product price is increased. It successfully solves the inadequacy of the original equipment and brings direct economic benefits of more than 1.5 million yuan per year.
