1. Main use Impact hammer crusher is suitable for mining, building, chemical industry, electricity, metallurgy and others. Various materials with compressive resistance than 140 Mpa such as mining stones, limestone, coke, coal, etc can be crushed. This machine can not be used for ore or viscous material which surface moisture content≥10%. 2. Advantages a. Advanced structural design, the perfect combination of advantages of Impact crusher, hammer crusher and single-stage hammer crusher. 600-1500mm initial materials can be crushed directly to the finished material. b. Long enough crushing chamber, and is continuous. Materials can be fully crushed, little over crushed and high percent of pass of finished products. c. Impact plate is fixed, good rigidity and high strength. d. Without sieve structure, the materials are discharged smoothly. Effectively increase production while reducing the hammer wearing. e. Advanced pad device an effectively control the particle size. f. Racks hydraulic opening; repair and maintenance easy and fast. g. Hammerhead use high quality wear-resistant materials, much more wearing than ordinary ZGMn13 and can be more using life. The processing capabilities listed in the form shall vary according to different working conditions.
