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
