When coalcutter works, coal cutting roller 1 is rotated, and is peeled off coal cinder by the effect of tunneling gear 2, generation during this
The largely dust that disperse everywhere, in order to realize depositing dust purpose, traditional spraying system often takes two ways, and a kind of way is
Directly a wide range of spraying, although improving the spatial dimension of depositing dust, spraying intensity inevitably declines, the efficiency of depositing dust
It is lower, and the spraying constructing operation for also influencing worker on a large scale, it is directly to be sprayed at coal cutting roller 1 that another kind, which does rule,
Spray intensity is higher, but this mode reduces spraying range, causes some dust to disperse departing from spread of spray, together
Sample affects the effect of depositing dust.
