In the design and optimization of crusher, impact time is an important parameter that must be considered. The impact time is refers to from the contact impact began to contact separation duration, heavy affects on the structural design,crushing efficiency of impact crusher , effect of crushing ratio and production capacity greatly. Below through the several factors affecting the impact of time one by one, so as to provide a theoretical support for the design and optimization of crusher.

(1) in different conditions
Impact collision plate hammer assumption rock, to a certain speed to fly to counterattack plate, the rock itself not broken. Analysis of maximum displacement respectively on the plate hammer and rock just contact moment, the plate hammer and rock just separate moments, find the maximum displacement of rock appears in the rock below the center with the plate hammer arc angular contact at.
(2) the impact velocity
Change the size of the impact velocity, the other conditions remain unchanged, on the impact of time under different impact velocity is analyzed, it is found that the impact of time with the impact speed increases the magnitude of change is not big, and the impact velocity and impact time linearly. The impact time and impact velocity under the small short.
(3) the material granularity
The choice of different particle size of rock, the analysis on the impact time, the greater the diameter of material impact longer. The impact of time - and between the material of different grain size impact velocity curve is basically parallel.
(4) the shape of the materials
The shape of every kind of material may be very irregular, and. Based on the shape of the materials is not the same impact time analysis of such conclusions: with the increase in length of the material, namely shape becomes large, the impact time increases. The impact of time between the same shape and size of different rocks differ not quite, comparability is not strong.
(5) wear plate hammer
Plate hammer wear is not at the same time, the impact of time variation is big, therefore affecting the impact time less.
