We should consider about the capacity, max feed size of raw feldspar, required output size and so on.Secondly, we should consider the production details of the crusher plant in order to determine which models we should adopt.
It is a still bottoms from the above-described nonylphenol process and is adducted with 2 parts by weight of ethylene oxide per weight of still bottoms. One product of this type is sold commercially under the designation OX153 l2.The reaction between the alkyl still bottoms and the ethylene oxide is well known to those slc'lled in the art, and commercial products of this reaction are readily available on the market.
Fine powder bin inlet pressure is with the sectional type pid control algorithm of feedforward compensation, fine powder bin inlet pressure setting value and fine powder bin inlet pressure value of feedback subtract each other the input forming material distributing valve opening controller, be converted into the reference value of material distributing valve aperture by switchable controller, compensate with material distributing valve aperture and be added the execution value becoming material distributing valve aperture and go to control bowl mill.
Level Four is joined concrete needs 80～150mm, 40～80mm, four kinds of coarse aggregates of 20～40mm, 5～20mm, and promptly four kinds of aggregates need sieve out in the regrading system.e.The technology arrangement of this kind regrading system, single line need be provided with 8 of sealing-tape machines, i.Usually the regrading system divides the second order tiled arrangements. 1 charging sealing-tape machine, article 1, abandon the material sealing-tape machine, 2 single orders advance the second order sealing-tape machine, go up precooling storehouse sealing-tape machine for 4, single order second order screening Lou Erzuo is to build high peak intensity 20 * 10 the concrete system design moon4m3System be example, system takes up an area of and to be 6500m2, 130m * 50m, two-wire is arranged.Enter the material of 5～150mm of the system of mixing and stirring, need through the single order sieve, sieve aperture is made as 40mm, 5mm, be classified as 40～150mm, 5～40mm,＜the 5mm material; 40～150mm, 5～40mm send into the second order sieve, and＜5mm material is sent into and abandoned stockpile; The second order sieve is established the screening machine of two kinds of sieve apertures, the screening machine that the material of 40～150mm is sent into, and its sieve aperture is made as 80mm, and the material of 80～150mm, 40～80mm is distributed into the corresponding aggregate bin in precooling storehouse after the classification; The screening machine that the material of 5～40mm is sent into, its sieve aperture is made as 20mm, and the material of 20～40mm, 5～20mm is distributed into the corresponding aggregate bin in precooling storehouse after the classification; Be the common technology arrangement of regrading system.
