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…

Hydraulic double roll crusher offer significant advantages over spring double roll crusher in terms of technical performance, operational efficiency, and long-term economic benefits. The following is a systematic analysis: 1. Core Performance Comparison Intelligent Adjustment and Precise Particle Size Control Hydraulic system dynamic adjustment: The hydraulic cylinder adjusts the roller gap in real time (precision ±0.1mm), with an output particle size error of ≤3%, ensuring uniform particle shape of the finished sand and gravel (cubic particle ratio ≥95%). Spring equipment limitations: Manual adjustment of spring tension is required, with an error of ≥10%, and frequent shutdowns are needed for adjustment after roller lining wear. Efficient overload protection and stability Hydraulic automatic avoidance: When encountering metal foreign objects or ultra-hard materials, the hydraulic system instantly increases the roller gap to expel the foreign object and automatically resets, reducing fault recovery time by 80%.>Spring passive compression: Relying solely on spring cushioning, manual cleaning and reset are required after hard objects pass through, which may cause component deformation or breakage. Significant energy savings and reduced consumption Hydraulic transmission is 20%-30% more energy-efficient than mechanical transmission, with power consumption of only 0.8-1.2 kWh/ton (spring-type: 1.2-1.8 kWh/ton). The hydraulic system dynamically adjusts power output to…
Granite as a high hardness rock (Mohs hardness 6-7), its sand making process requires high wear resistance, crushing efficiency and particle size control. So how about the effect of granite crushing and sand making with roll crusher? High-precision particle size control and high-quality finished products Uniform and controllable particle size: Through hydraulic or mechanical adjustment of the gap between the two rollers (adjustable from 0-5mm), the particle size of the discharged material can be precisely controlled, and the finished sand is full of grain shape, well-graded, with stable fineness modulus, which can satisfy the requirements of high standard of construction sand (e.g., concrete aggregate above C60). Low over-crushing rate: the principle of extrusion crushing reduces the generation of stone powder (over-crushing rate <5%), which improves the proportion of high-value sand materials, and the rate of sand can reach 99%. Wear resistance and equipment life of roll crusher Strengthened wear-resistant parts: Roll crusher roll skin adopts 20cm thicker high chrome alloy or tungsten carbide liner, with hardness of HRC62 or above, which has a life span of up to 1-3 years when dealing with granite and reduces the frequency of replacement.
