GFP serial high efficiency jaw crusher without attrition, a key item of the eighth China national science and technology five year plan, adopt optimum design with dynamic flank angle theory, which increase crushing force to materials and greatly decrease sliding of crushing process, realizing high efficiency with no friction.
This series products adopt design method of toggle plate support, zero suspend of swing-jaw plates, small eccentric distance, high wobble frequency, and deep hyperboloid chamber, which show features of big reduction ratio, high throughput, and low friction. It is upgrading product of previous jaw crusher, and have following advantages compared with previous jaw crusher:
1. Increasing throughput by 60-100%;
2. Decreasing current drain by 30-60%;
3. Improving service time of jaw crusher by 2-15 times;
4. Superior adaptability to materials.
