  • Selecting the Right Crusher for Quarry Operations Agg-Net

    For example, if a company can sell 500,000 tonnes per year, its crushers need to produce just short of 42,000 tonnes each month. If the crusher is set up to run three days a week (approximately 13 days a month) for 8h a day, the operation will require a machine capable of processing 400 tonnes/h.

  • Cold Crushing Strength ReStaR

    The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion. Refractories with high CCS are also expected to have higher

  • Lubricating crushing machines in quarries Rock to Road

    The actual crusher can be in the form of a cone, gyratory, impact, jaw, etc. type machine. Common to all crushers is the requirement for lubrication, be it oil lubrication (e.g. for gear boxes) or grease (e.g. for bearings). The pure nature of crushing rocks produces many possible issues and considerations to tend with on a daily basis.
