Impact time refers to the duration from the beginning of contact to the end of separation, which has great influence on the structure design, crushing ratio, crushing efficiency and production capacity of crushing machine. Which factors affect the impact time of crushing machine?
(1) Impact speed
Through the analysis of the impact time with different impact speed under the same situation by change the impact speed, we found that the impact time does not change a lot with the change of impact speed, basically in linear relation. Smaller impact speed, shorter impact time.
(2) Material granularity
Using the different size of ore to analyze the impact time, found that the larger the material diameter, the longer the impact time. The curve of impact time and impact speed on different materials is parallel.
(3) Material shape
The shape of Materials are various and irregular. Through the analysis of impact time on material shape, we get the following conclusion: the impact time increases with the enlarging of material length, i.e. the shape enlarged.
(4) Plate hammer abrasion
Plate hammer abrasion has small influence on the impact time, that is to say the impact time changes little in different abrasion.
