Contrast of Vertical Shaft Crusher and Horizontal
In the crusher test experiments, the short head crusher parameters are 0 and l ,values were taken are separately 0.2, 0.5 and 2.5, a large selection of fine grade is 0 value, because it will produce more fine-grained level. Grading function b = 10 mm, q = LT / h and e = l J / kg were taken with reference to the feed rate and unit mass impact, other parameters are k = 0 95, s = 0.2 and n = 0 73. The rotor radius R = 0.325 m; the rotor impact plate height H = 0.lm. The limestone crushing materials used in the experiment, through the sieve feed particle size control, particle size control in the 14-20 mm. Fragmentation function parameters the following numerical fine grade b = 0 35: m = O.5 and l = 2.5.Mining crusher refers to the crushing machinery whose content is more than 50% of the total content, the row compound particle size is greater than three millimeters. It is invented by British Hengan.
After the the improved
impact crusher model can predict
the steady state performance, the model has a range of parameters. Performance
impact crusher can be combined with the grading function to illustrate the
classification function depends on the unit mass of the impact energy, rotor
rate and feed rate.The crusher is widely used in mining, metallurgy, building
materials, road, railway, water conservancy and chemical industry and many other
sectors. Common crushing machines are winnowing mill, hammer crusher, impact
crusher, roll crusher, compound crusher. Jaw crusher (jaw crusher), having large
crushing ratio, uniform particle size, simple structure, reliable operation,
easy maintenance, operating costs and economic characteristics. PF-I series
impact crusher can process materials side length is 100 to 500 mm, the
compressive strength is up to 350 MPa, great crushing ratio, cubic particles
advantages of material was broken; PF-II series impact crusher machine, suitable
for crushing hard materials, such as cement crusher, with a production capacity
of the material advantages of small particle size.
According to the results of the analysis of particle dynamics,
the quality of the units of the vertical shaft impact crusher impact than the
large horizontal axis. Model prediction with experimental results are
qualitatively substantially the same, these assumptions the parameters of the
constant impact energy and a function of the feed rate, with a suitable formula
of its expression, to obtain a better result.
