Embodiment Construction

[0009] The production method of the amino molding compound involved in the present invention is as follows: first, formaldehyde, urea and other auxiliary materials are reacted in a reactor to obtain urea-formaldehyde resin, and the urea-formaldehyde resin is added to pulp and other additives and entered into a kneader for meshing to obtain Slurry, the slurry is put into a drier to dry to obtain a solid material, the solid material has uneven particle size and contains many block materials. The drying moisture of the solid material is controlled below 5%, preferably around 3%; tests have proved that when the moisture of the solid material is controlled at 3%, the crushing output of the high-speed eddy current pulverizer can reach up to 800 Kg / h; and When the moisture is about 5%, the crushing output will drop to about 500 Kg / h. The lower the moisture, the better the crushing effect and output, but it is extremely difficult to control the moisture of the aforementioned solid mat...

Abstract

The invention discloses a smashing device for manufacturing amino molding plastic. The smashing device comprises a rack, wherein a housing case is arranged on the rack; a main shaft penetrates through the rack and is connected with two end surfaces of the housing case through a bearing saddle; both ends of the housing case are respectively provided with a feeder and a discharging device; the housing case is internally provided with a smashing cavity; the smashing cavity is internally provided with a knife rest on the main shaft; blades are distributed on the knife rest in the circumferential direction. The smashing device is characterized in that the blades are in clearance fit with the inner wall of the smashing cavity, and the clearances ranges from 1mm to 2mm; each circle of blades distributed in the circumferential direction are designed into a group, and the clearance between each two adjacent groups of blades is 0.5mm-1.5mm. The smashing device has the beneficial effects of being capable of increasing smashing efficiency and controlling the feeding speed of materials, so that the feeding speed is matched with the practical capacity of a smashing machine.

Description

technical field [0001] The invention relates to a crushing method, which is mainly applicable to the production of amino molding plastics and belongs to the field of chemical production. Background technique [0002] Amino molding compound (see GB13454-92 for details) refers to a chemical raw material made of urea-formaldehyde resin or melamine-formaldehyde resin as the base material, adding cellulose, hardener and other additives, mainly used for pressing into tableware and electrical appliances Structural parts such as switches. The existing amino molding production methods and equipment have disadvantages such as low degree of automation and insufficient efficiency. Most of the production equipment is ordinary chemical equipment, which lacks pertinence to the amino molding compound itself. The invention relates to a pulverizing method for pulverizing materials in the production process. The existing pulverizers have the disadvantages of low production efficiency, high po...
