Contact with the spherical ball corners problem tile with hollow shaft journal: Some people think that the spherical hollow shaft journal tile mating contact angle majority of small package good, at least should not be <60 degrees, it is not true, because the national building materials industry Standard JC334.1-94 provisions of Article 4.3.2.1c saving ball mill, the "contact angle package should be <35 degrees, which is summed up in accordance with a lot of practice, in theory, the smallest corners depending on its material bearing alloys Since mill equipment bearing alloy is a soft material under gravity simplified, bearing alloy to produce certain deformation, so that the contact angle is too small package is not good, when the contact angle is relatively small package, can effectively ensure the hollow shaft journal in normal conditions will not hold tile, Furthermore, since the contact angle is relatively small package, there is a large range of angles of backlash, you can ensure lubricants smoothly into the contact area, thus ensuring lubrication beneficiation ball contact area, and facilitates the hollow shaft journal and spherical watt heat, we can see that the contact angle package should <35 ° is appropriate, at this time the processing axis Wawa surface becomes more efficient, easy to improve the quality of their contact surfaces. lattice-type ball mill After the discharge end of the original liner outer grid plate containing 12, 12 inner grid plate, outer liner 12, the inner liner 12 mill, center plate 2, instead of rubber lining, inner and outer rings blocks grid plate, center plate unchanged, the number of blocks lining the inner and outer rings are the same, only the name change is called for the discharge chute installed inside and outside the ring rubber grid plates, rubber center of the plate is fixed by the pressure of the rubber mill equipment, www.zzyuxi.com rubber grid plate and rubber batten sizes according to customer requirements.
