Mobile roller sand making machine is a kind of mobile sand production equipment integrating crushing, screening and conveying functions, which is especially suitable for mobile operation scenarios (such as construction sites, mining temporary mining).
Mobile Roller Sand Making Machine
1. Core structure and working principle of Mobile Roller Sand Making Machine
Modular integrated design
The equipment integrates roll crusher, vibrating screen, feeder, conveyor belt and control system in one unit, equipped with wheeled or crawler chassis to support rapid transfer.
Roll Crushing Principle
Material is crushed by squeezing and shearing when passing through the gap of double rolls, and the roll surface can be customised to be flat rolls (fine-grained sand making) or toothed rolls (coarse crushing of medium-hard materials), and the discharge size is adjustable from 1-40mm.
Intelligent control system
is equipped with PLC automatic adjustment system, realising one-key start-stop, pressure adaptive anti-jamming, and some models support remote monitoring.
2. Core Advantages
Flexibility and cost saving
No infrastructure installation: directly stationed in the work site, eliminating the fixed production line infrastructure costs and material transport costs.
Follow the mining surface movement: suitable for stage-by-stage projects (e.g. road construction), reducing equipment idling.
High-efficiency sand making performance
High yield: Roll crushing reduces over-crushing, and the finished sand has uniform grain shape (>80% cubic), and the grading is in line with the standard for construction sand.
Wet material adaptability: optional scraper device can solve the problem of sticky rollers for materials with moisture content ≤ 35%.
Energy saving and environmental protection
Energy consumption reduced by 20%-30%: compared with traditional sand making line, the hydraulic system optimises power distribution.
Dust and noise control: sealed body + dust removal module, operation noise <75dB.

3. Technical highlights of Huashengming products
Wear-resistant roller skin technology
High chrome manganese alloy roller surface is specially heat-treated, with a life span of 2-3 years (about 1 year for ordinary equipment), and support for life-long replacement-free roller body customisation.
Power and regulation system
Oil-electric dual drive: diesel engine/motor switching, suitable for mines without electricity.
Spring + hydraulic dual adjustment: precise control of the particle size of the material, overload automatic protection.
Customised Production Line Configuration
supports ‘crushing before screening’ or ‘screening before crushing’ process, and can be combined with jaw crusher (coarse crushing) and cone crusher (medium crushing) to form a multi-stage crushing system.
Note: The whole system supports the customisation of mobile chassis, and the crawler type is recommended for models with an hourly output of more than 100 tonnes.
4. Applicable Scenarios and Materials
Typical industries:
Construction waste regeneration: on-site crushing of concrete blocks, bricks and tiles, and regenerated aggregate for road base filling.
River pebbles/granite sand production: direct output of mechanism sand, replacing natural sand resources.
Mining temporary mining: mine face propelled operation, reduce the cost of ore transit.
Applicable materials: rocks, ores, construction waste with compressive strength ≤160MPa, and can still operate stably when the moisture content is ≤35%.
5 Procurement Recommendations
Capacity Matching
Small project (≤20t/h): choose 2PGT400×250, cost 30,000-100,000 RMB, occupying an area of <50㎡.
For large-scale projects (≥100t/h): 2PGY1800×1000 is preferred, with screening module to form a mobile production line.
Main points of operation and maintenance
Anti-sticky rollers: high wet materials (such as silty soil) need to be installed with scraper.
Regular maintenance: check the roller surface wear, tighten the bolts, and keep the lubrication system normal.
Service Guarantee
Huashengming and other manufacturers to provide with material test machine, installation in the factory, 24-hour fault response (contact Manager Fan 152-380-22995).
Mobile roller sand making machine has become the core equipment for the transformation and upgrading of the sand and gravel industry with the characteristics of ‘mobile production and controllable granularity’. Through wear-resistant technology, intelligent control and customised service, Huashengming Heavy Industry further strengthens its competitiveness in the mobile sand making scene. When purchasing, it is necessary to integrate production capacity, material characteristics and after-sales response ability, and give priority to suppliers that support on-site testing.
