Urea-formaldehyde resin rubber powder crushed at room temperature is divided into coarse crushing, medium crushing and fine crushing. Foreign coarse crushing and fine crushing equipment generally adopt rolling shear structure. China's rubber urea-formaldehyde resin glue crushing equipment mainly has the following ways:

1. Roller crusher. This is the crushing equipment traditionally used in the reclaimed rubber industry, which is divided into three types: double groove roller, single groove roller and double light roller, with shearing and extrusion effect. For radial tires, the double groove roller has the effect of rubbing the steel wire, the single groove roller is coarse crushing, and the double light roller is medium crushing. The equipment crushes urea-formaldehyde resin glue powder with a particle size of about 32 mesh.

2. Toothed disc crusher. This form of equipment can be used for both coarse and fine crushing. At present, many manufacturers in China manufacture according to the relative movement of the dynamic grinding disc, resulting in shearing, grinding, the structural form is divided into flat grinding and cone grinding, mostly used in the fine crushing process, and achieve good results.

3. Screw extrusion crusher. The rotor spiral is tooth-shaped, variable distance, variable diameter screw, can make the material compressed, crushed, steel wire or fiber separated in the same working room to complete, at the front end of the screw is provided with a particle size control panel to adjust the particle size of urea-formaldehyde resin powder. The machine can be used as an ideal equipment for medium crushing.

4. Grinding wheel crusher. It adopts the principle of rubber abrasion testing machine, grinding rubber with special grinding wheels, which has the advantage of obtaining finer urea-formaldehyde resin rubber powder at one time, but the processed materials need to be prepared in advance into strips, which brings inconvenience to continuous production. The roller mill mainly cuts and crushes waste rubber for many times in the process of moving the knife and the spindle rotation process of the fixed knife spindle, and is mostly used for coarse crushing. It is often used abroad for the pelletization of pure rubber.
