The mineralized river bed sand gravel crusher(Double-roll crushers) represent an excellent solution for crushing riverbed gravel in mineral processing, particularly in scenarios where product shape is critical and minimizing fines generation is a priority. 1.. What is “mineralized riverbed gravel”? Mineralized riverbed gravel typically refers to: A mixture of sand and gravel within natural alluvial deposits Containing heavy minerals such as native gold, platinum group metals, cassiterite, ilmenite, and zircon Particle size: 0–150mm, commonly 5–60mm pebbles + sand Physical properties: High hardness (predominantly quartz, flint, granite pebbles), highly abrasive, often containing silt and water 2.Advantages of Double Roll Crushers (Why Are They Suitable?) Excellent Particle Shape: Employing the principle of compression crushing, double roll crushers produce material particles predominantly in a cubic shape with low content of needle and flake particles. This is highly advantageous for applications requiring well-shaped aggregates, such as concrete aggregates. Minimal Over-Grinding: Compared to hammer crushers or impact crushers, double roll crushers generate a lower proportion of powder (stone dust) during crushing. This better preserves the desired particle size of sand and gravel, increasing the yield of finished products. Simple Structure, Easy Maintenance: The mechanical structure is relatively straightforward, making operation and maintenance relatively simple with…

What is the working principle of smooth roll crusher? The working principle of the smooth-surface roller crusher is based on the squeezing and grinding action generated by the relative rotation of two rollers. Uniform crushing of materials is achieved by controlling the gap between the rollers. 1. Core Crushing Mechanism Material Entrapping and Compression Material falls from the feed inlet between the two rollers and is drawn into the gap by roller surface friction. The two rollers (fixed and movable) rotate at low speeds in opposite directions (typically <4 m/s linear velocity), applying high compressive pressure to the material. This generates internal fractures and causes fragmentation. Smooth Roll Characteristics: Featuring a smooth roll surface, this mechanism primarily relies on compression and grinding forces. It is suitable for medium-hard or brittle materials (e.g., limestone, coal), producing well-shaped particles with low over-crushing rates. Overload Protection Mechanism When non-crushable objects (e.g., iron pieces) enter, the movable roll automatically retracts via springs or a hydraulic system, widening the roll gap to discharge foreign objects before resuming its original position, preventing equipment damage. Discharge Control Crushed material discharges from beneath the roll gap, with particle size directly determined by the gap width (typically adjustable from…
