It is a newly developed product of hammer crusher, named according to its no-grate and reversible characteristics. It can solve the blockage problem due to high humidity, improve the utilization rate of hammer head, reduce its exchanging  frequency and ensure the even
granularity  of products. This series of product is the main equipment applied in metallurgy, building material, chemical, hydropower and other industries for fine crushing of materials with medium hardness and below such as coking coal, small-size limestone, plaster, alum,
brick, tile, etc. The crushed material should have compressive  resistance less than 150Mpa and surface moisture less than 15%.

The main part consists of

1.Frame         
2.Rotor
3.1mpact rack   
4.Adjusting part

Parameters:

• No grate               
• large crushing ratio
• large production   
•Small over-crushing amount
• Reversible rotor    
• Long service life of hammer head
• Low operating cost
