Choosing the right mobile roller sand making machine requires comprehensive raw material characteristics, capacity requirements, mobile configuration and long-term operation and maintenance costs, the following is a scientific selection guide: 1. Adaptation of raw material characteristics Hardness and composition Medium and low hardness materials (limestone, gangue): directly choose the standard roller surface models (such as 2PGY800 × 800), roller skin material for high manganese steel can meet the demand. High hardness materials (granite, basalt): need to choose composite alloy roller skin or increase the jaw pre-crushing, to avoid excessive wear of the roll surface (such as 2PGY1800×1000 with pre-crushing module). Wet and sticky materials (mud content>15% or water content>25%): scraper cleaning device must be selected to prevent sticky rollers from clogging (WMS model supports customised scraper). 2. Mobile configuration options Crawler chassis: adapting to rugged terrain, preferred for projects with hourly output ≥100 tonnes (e.g. 2PGY1500×1000), with a 50% increase in transfer efficiency. Wheeled chassis: suitable for frequent movement on flat sites, low cost (standard for small models). Integrated design: screening + conveying module integration, reduce auxiliary equipment investment (medium-sized models and above support customisation). 3. Special scenario solutions High wet material processing (such as silty soil) Add hydraulic scraper...

Can roll crusher crush steel slag? The answer to this question is yes, the roll crusher with its high efficiency and reliability has become one of the preferred equipment for crushing steel slag. Double-roller crushers are suitable for crushing steel slag, but their applicability depends on slag characteristics and equipment performance. Below is a detailed analysis: 1. Applicability Analysis A. Compatibility with Steel Slag Properties Steel slag typically has high hardness (compressive strength: 150-200 MPa) and brittleness. Double-roller crushers utilize dual-roller shearing and compression forces to effectively break down such materials, especially for medium-to-fine particle size requirements (e.g., ≤10 mm). For instance, tests show that adjusting roller gaps can crush steel slag to 1-3 mm, meeting sintering or grinding process needs. B. Equipment Performance Wear Resistance: Rollers made of high manganese steel or chromium alloys, enhanced with hardfacing technology, withstand abrasion from metallic components in slag. Overload Protection: Hydraulic systems automatically retract rollers to avoid damage from oversized slag blocks. 2. Core Advantages A. Precise Particle Size Control Adjustable roller gaps (1-40 mm) enable flexible output customization (e.g., 3-5 mm for cement raw materials or 1-3 mm for sand-making). Post-adjustment, slag uniformity exceeds 90%, minimizing over-crushing. B. Economic and...
