1、 Different sizes of shredder manufacturers There will be scale differences among shredder manufacturers. Some manufacturers are only small and medium-sized processing manufacturers, and they will have great differences in equipment quality control and production process. Because the scale is larger, it represents the production strength. The scale manufacturers have strength advantages in technology, equipment and other aspects, and because they have the scale of manufacturers, they will also recognize the materials of equipment The real choice can guarantee the quality of products. On the contrary, if it is a small-scale manufacturer of dual shaft shredder , one of them has no strength in production. In order to reduce the price of equipment, the production cost will be reduced from many aspects. Therefore, in production, both the material and selection and the technology will be greatly reduced. 2、 Different core technologies The dual shaft shredder equipment itself is not a high-t
