As a typical intermediate and fine crushing equipment, the double roll crusher combines the triple mechanical effects of extrusion, shear, and grinding in its crushing process.
The entire crushing process is divided into the following five stages
Stage 1: Pre screening enters the roller crusher
Materials exceeding three times the gap are intercepted by the pre sieve
Qualified materials slide into the feeding area at a speed of 0.8-1.2m/s along the natural angle of rest
Stage 2: Initial biting of the double roller crusher
Form a forced feeding flow, biting into a depth of 1/8 of the roller diameter
Stage 3:double roller crusher laminating crushing
The material particles undergo three rounds of crushing
Stage 4: Grading of finished products discharged from the double roller crusher
The thickness flow effect at the gap forms a particle size screening layer
Stage 5: Forced discharge of double roller crusher
Set the angle of the scraper plate to 45 ° to reduce material stickiness
The crushing process of the roller crusher is actually a system engineering of multiple physical field coupling effects. The transition from traditional “rigid extrusion” to “flexible crushing” is becoming a new direction for improving equipment efficiency., The new generation of units has achieved a 22% reduction in crushing energy consumption and a 40% reduction in metal consumption. In the future, this technology will demonstrate greater application value in the fields of fine sand and gravel production and industrial solid waste treatment, promoting the continuous advancement of crushing processes towards energy conservation and intelligence
