Technical field
The present invention relates to a kind of prilling method of rosin, paraffin, potassium chloride low softening point mixture.
Background technology
The present invention wants the material of granulation to be mixture, and wherein rosin, paraffin are organic matter, and potassium chloride is inorganic salts, has following characteristics: (1) rosin, paraffin organic matter can heating for dissolving, and potassium chloride inorganic salts cannot heating for dissolving; (2) rosin and paraffin (fusing point 56-58 DEG C) mixing, the softening point of mixture significantly reduces, and is low to moderate about 50 DEG C.Above-mentioned material adopts traditional prilling; all come with some shortcomings: (1) revolution steel belt condensation comminution granulation; upstream process heat is melted on the steel band of state material by the uniform thereunder at the uniform velocity movement of comminutor distributing device; continuous spray, cooling device is provided with below steel band; force the material on steel band to be able to quick cooling, solidification at moving process, thus reach the object of granulating and forming.In product of the present invention, material is due to containing potassium chloride, and the sedimentation stability under high temperature melt state is bad, easily sedimentation occurs, and causes material uneven; In addition, potassium chloride solid phase particles at high temperature can block the pipeline of coupled reaction still and distributing device and the duct of distributing device, causes suitability for industrialized production to realize; (2) horizontal screw extruding pelletization method; low softening point material through mixing, kneading is under screw rod transmission, squeezing action; extrude from head perforate template; finished granule is obtained again through super-dry or cooling; thus realize object powder product being changed into uniform grain products; during material employing horizontal screw extruding granulator granulation of the present invention; because material softening point is at about 50 DEG C; the strip-shaped materials extruded is difficult at short time cooling forming; so there is no intensity; can be bonded together again and clump together, cause granulation to realize.
Summary of the invention:
The object of the present invention is to provide a kind of prilling method of rosin, paraffin, potassium chloride low softening point mixture, produce particle evenly attractive in appearance.
The prilling method concrete steps of rosin of the present invention, paraffin, potassium chloride low softening point mixture are:
The first, the rosin of bulk was pulverized 40 mesh sieves;
The second, the rosin after pulverizing, paraffin, potassium chloride are poured in mixer mix by weight 45 ~ 65:5 ~ 15:30 ~ 40;
3rd, the material mixed is added vertical banded extruder (see Figure of description), control each section of temperature of banded extruder well, wherein the temperature of charging aperture controls at 5 DEG C ~ 20 DEG C, screw rod middle portion temperature controls at 70 DEG C ~ 110 DEG C, and die head temperature controls at 50 DEG C ~ 80 DEG C, the rotating speed of screw rod is controlled when 5 ~ 15r/min, and mixed material is extruded into strip in banded extruder;
4th, the strip-shaped materials extruded is first by air-cooled;
5th, the material after air-cooled drops on to rotate on steel band and carries out water-cooled again;
6th, through abundant cooled strip-shaped materials by trimmer shaping, namely obtain the product of suitable particles size.
Compared to the prior art the present invention has following feature and useful effect: 1, solve the granulation problem containing potassium chloride inorganic salts in low softening point material, and the uniform particles produced is attractive in appearance; 2, adopt vertical banded extruder to solve adhesion problems that horizontal banded extruder squeezes low softening point material; 3, by twice pressure cooling, namely air-cooled and steel band water-cooled, solves the cooling forming problem of low softening point material.
