1. The structure is simple and compact, the noise is low, the efficiency is high. 
2. The installation is flexible, basically needs no foundation.
3. The rollers' surface adopts anti-abrasive welding rod or exchangeable dental plate, the maintenance is simple.
4. Self-preservation ability is strong, the high-hardness materials (such as all sorts of metal block) won't break the equipment's parts when they enter the shredding breach.
5. The discharge gram size is adjustable, the minimum can reach 2-10 mm.   
Applicability
1. Widely applied to fine processing of building materials, metallurgy, chemical industry, coal etc crafts.
2. Especially applied to the finement of the clinker, adjusting the grinding mill grading can increase productivity 30-50%.
