Basalt Sand Maker – Built for High-Hardness Material
Basalt is a recognized difficult-to-process material in the sand-making industry due to its high hardness and strong abrasiveness. Traditional crushing equipment processing basalt commonly faces issues such as rapid wear, high energy consumption, and inconsistent product quality. HSM roller sand maker, designed specifically for basalt crushing challenges, employs the lamination crushing principle and has been proven stable in multiple projects.
I. Industry Challenges in Basalt Sand Making
Basalt (Mohs 5–7) is a high-hardness material. Traditional hammer or impact crushers cause rapid wear, frequent downtime, excessive flaky particles, poor gradation, and high energy costs. These issues raise overall production costs and demand better equipment selection.
II. HSM Roller Sand Maker Solution

HSM roller sand maker adopts the double-roll lamination crushing principle – two highly wear-resistant rollers rotate toward each other at low speed. Material entering the V-shaped crushing chamber between the two rolls is subjected to continuous high-pressure compression and shearing forces, being “crushed” rather than “shattered” through squeezing, shearing, and grinding. This low-impact, high-pressure compression method reduces impact fatigue on the equipment body, making it more suitable for high-hardness, highly abrasive materials.
Extra wear-resistant roll shells extend service life
To address basalt’s high abrasiveness, HSM roller sand maker uses high-chromium manganese steel alloyed with rare metals for the roll shells, offering high surface hardness and strong wear resistance. The average service life of the roll shells far exceeds that of ordinary hammers, effectively reducing wear part replacement frequency. The roll shells feature an extra-thick design, and local wear can be repaired on-site by turning without complete disassembly and replacement, significantly reducing maintenance costs.
Superior product quality meets engineering standards
Lamination crushing causes material to fracture along natural cleavage planes or mineral boundaries, producing cubical particles with low flakiness content and proper gradation. Discharge size can be precisely controlled via the hydraulic system to meet different project requirements for aggregate gradation. The finished sand fully meets construction sand standards and is especially suitable for C50 and above high-performance concrete.
Optimized energy consumption lowers operating costs
The roller sand maker operates on a static pressure principle at low speed, achieving higher energy efficiency than high-speed impact crushers. Compared to impact crushers, it saves 20% to 30% energy, with significantly reduced electricity consumption per ton. Equipment noise levels are also lower than traditional impact crushers.
Hydraulic protection ensures operational safety

The equipment is equipped with a full hydraulic automatic adjustment system that compensates roll gap during operation, maintaining discharge stability in continuous production. When uncrushable material enters, the hydraulic system automatically retracts, expels the foreign object, and resets, preventing equipment damage.
III. Application Scenarios
HSM roller sand maker is suitable for feed sizes under 80mm and product sizes ranging from 50 mesh to 20mm in fine crushing applications, capable of processing materials with compressive strength ≤160MPa.
Main application scenarios include:
-
Highway and railway aggregates: Basalt aggregates offer high compressive strength and strong abrasion resistance, suitable for high-grade pavements and bridge structures.
-
Airport runways and port facilities: Basalt aggregates have low crushing value and good durability, meeting the stringent requirements of high-standard engineering projects.
-
High-performance concrete: Manufactured sand with regular particle shape and proper gradation, suitable for C50 and above concrete grades.
IV. Model Configurations
HSM roller sand makers are available in a complete range of models covering different capacity requirements, from small spring-type units to large full-hydraulic models. Based on material characteristics and production requirements, roll shell material, discharge size, and motor power can be customized to ensure precise matching with project needs.
