Existing problems and reform of the hammer crusher
Existing problems and the reform of a hammer crusher:
1, the existing problems
The original machine adopts double frame of the screen, but because the screen door on average half a frame directly the impact of the rotor and chalk, which is conducting a broader environment and less likely on both sides . After excessive wear of the installation image half-screen average of the causes of insecurity and appearing generally the phenomenon of loose and peeling, resulting in a number of maintenance work.What s "In addition, the median wear of the screen is equal to that of the screen about 14% of the surface material have been supported in place, the broken limestone formed here can be removed, part of the chalk in a crusher broken several times, leading to low efficiency of the broken-time performance is not high.
2, measures reforming
Remove part of the screen half of the average and change the course of vice l'écran home twice for one and then change the display section 2-1 of the original roots item screen root.
The material of the section of the screen remains unchanged while rab complete melting of strengthening the middle section of the screen to increase the strength of the display section
And keep the distance between the hammer rotating section of the screen after the transformation invariant.
3, The effect of the reform
Due to the suppression of vice-half median part of the section of the screen, chalk spray qulified coal through the control area increased by 14%, or section, and improve the crusher crushing efficiency increased production to 65 ~ 75 t / h. Limestone consumption of old 2.4 kWh / t was reduced to 2.0 kWh / t.For vice hammer alone 15,000 tons of gravel, but after the reform due to increased production, 25,000 t just need to change the gravel with a hammer vice.
And the life of the part of the screen and the screen section months before. Because white paper extended for six of the original article is easy to wear a sieve, which often leads to repair of the machinery and a number of maintenance work and assign production.The problem was solved after the Reformation, and each month it will save you 2 pack stainless steel rod.
