Roller Crusher Sand Yield In-Depth Analysis
2025-05-22The yield of roller crusher in sand production is generally in the range of 85%-98%, which is significantly higher than that of vertical shaft impact crusher (60%-85%). The core mechanism of its high yield lies in: 1. Squeezing crushing principle: the laminar crushing force generated by the double rollers rotating in opposite directions makes the material uniformly subjected to force in the closed chamber. And the over-crushing rate is lower than that of the impact crusher by more than 50%. 2. Intelligent gap adjustment: Hydraulic/spring system can achieve 0.1mm precision control of roll pitch. Which ensures that the qualified rate of material size is increased to 98%. 3. Material adaptability: for medium-hard materials (compressive strength ≤ 160MPa) such as river pebbles. Limestone, etc., the yield can be stable at more than 90%; construction waste recycling field measured up to 95%. Three major factors affecting the yield rate Characteristics of raw materials Hardness threshold: when the material Moh’s hardness>7 (such as granite), the yield will drop 8-12%. High chrome manganese steel rollers (3 times longer service life) Moisture content control: raw material humidity>5%, sticky roller phenomenon leads to a sudden drop of 15% yield. Use a pre-drying or water-mist dusting system….

Dry coarse salt crusher: Can dry coarse salt be crushed by roll crusher?
2025-05-20It is possible to use roll crusher for dry coarse salt, and roll crusher has advantages in particle size uniformity, production energy consumption and maintenance cost in crushing dry coarse salt. The following is a detailed description of the advantages of roll crusher for crushing coarse salt. Roll crusher is suitable for brittle materials with compressive strength ≤160MPa, and the hardness of coarse salt is low (Mohs hardness is about 2-3), which is much lower than the upper limit of the equipment load. Its extrusion-shear crushing principle can effectively handle such low and medium hardness materials. And the discharge size is uniform (1-20mm adjustable). The roll crusher controls the discharge size by adjusting the roll spacing. Which is suitable for crushing coarse salt to medium or fine crushing level (e.g. 1-3mm). The dry coarse salt has low moisture content (<6%), which will not cause the roll surface to stick or clog due to stickiness. And it meets the requirements of the roller machine for materials with low moisture content. Dry coarse salt crusher Advantages and Notes Advantages Low over-crushing rate: Roller squeeze crushing reduces the generation of fines. Making it suitable for scenarios where particle integrity needs to be preserved…
