Horizontal Impact Crushers (HSI) are designed for high volume and high reduction ratio impact crushing. They are particularly suitable for limestone or in applications where typical compression crushers such as Jaw and Cone would have difficulty in dealing high clay content or meet strict particle shape requirements. Horizontal Impact Crushers are generously and properly designed for primary crushing in a wide range of applications when processing low abrasive materials. These machines are known for their unique ability to process rocks at reduction ratios up to 16 to 1.
HIS Crushers (Horizontal Shaft Impact crusher) are widely used for sand and rock producing in the industry of roads, railways, reservoir, electricity power and building materials and so on with cubical shape.
The HSI crushers break rock by impacting the rock with hammers that are fixed upon the outer edge of a spinning rotor. HSI’s are used in recycling, hard rock and soft materials. In earlier years the practical use of HSI crushers is limited to soft materials and non abrasive materials, such as limestone, phosphate, gypsum, weathered shales, however improvements in metallurgy have changed the application of these machines.
