In order to improve service life further, the cross sectional shape of described projection can be rectangle, trapezoidal, L shape, T-shaped, convex etc.The preferred cross sectional shape of raised nubs is trapezoidal, though handling ease, use in have the also difficult drop-off that weares and teares.
In order to improve the wearability of roller further, the height that described projection exceeds roll surface accounts for 15% ~ 30% of projection whole height.Improve wearability and service life simultaneously.
In order to improve the one-pass finished rate of roller further, the height that projection exceeds roll surface is 4 ~ 7mm.
In order to improve the service life of roller further, the height that the projection of the same rib of described composition exceeds base roll surface is consistent.
The shape that above-mentioned projection is formed in matrix surface arrangement can be in-line, zigzag, herringbone, arc etc.Be preferably in-line, be beneficial to machined grooves and projection, effectively reduce cost.
In order to improve one-pass finished rate during roller crushing material further, the two ends of described roller are provided with rib, described rib is embedded between adjacent two ribs.As preferably, described rib and rib contour, improve one-pass finished rate further.
Above-mentioned projection can be a kind of or two kinds of dimensions, can form the projection of any width like this, reduces purchase cost, reduces mould and takes, enhance protruding versatility and interchangeability.
In the utility model, the monoblock type roller that described roller can be integrated for roll shaft and matrix also can be roll shaft and matrix is the composite roll of two parts.
beneficial effect
The utility model not only increases one-pass finished rate, also improves service life and wearability simultaneously.The utility model one-pass finished rate can reach 22% ~ 30%, and service life can reach 15000 ~ 20000 hours, and after using 2100 hours, wear extent is only 2.5mm.
