The claim of “handling 200 kinds of stone materials” may sound exaggerated, but those who have used it know that the high-pressure roller sand making machine is truly versatile in material processing. It can handle almost all materials with suitable particle size and low moisture content, from soft limestone and bluestone to hard granite and basalt, as well as construction waste and tailings slag. So the question arises: can it effectively crush vanadium-titanium iron ore, such a tough and highly abrasive material?
The answer is: it not only crushes it, but also operates stably and durably.
Vanadium-titanium magnetite is mainly distributed in Panxi area of Sichuan, Chengde area of Hebei and other regions, with a Mohs hardness generally above 6.5. It is rich in highly abrasive gangue minerals such as quartz and garnet, which act like natural sandpaper and cause severe wear to equipment. Ordinary hammer crushers suffer from severe pitting on hammers after just a few days of operation, leading to frequent maintenance and exorbitant costs. The high-pressure roller sand making machine adopts a completely different working principle – instead of high-speed impact, it uses two high-strength alloy rollers to apply hundreds of tons of controllable pressure, fracturing ores from the inside.
Ore Materials Crusher
This working mode offers three major advantages:
First, more uniform wear without severe abrasion.
Hammer crushers rely on point-to-point heavy impact, resulting in high local stress and easy chipping; roller crushers adopt surface contact extrusion with even force distribution, ensuring slow wear and long service life of roller shells.
Second, full-chamber feeding forms a material bed to protect the roller surface.
Continuous feeding fills the crushing chamber, forming a “material cushion” between the two rollers. This layer allows ores to crush each other through extrusion instead of directly impacting the metal rollers, effectively protecting the equipment with the materials themselves.
Third, high-quality roller shell materials resist wear.
Roller shells from regular manufacturers are integrally cast with high-chromium manganese steel, featuring dense structure and high hardness (HRC 60+). For extreme working conditions like vanadium-titanium ore processing, the roller shells can be upgraded with tungsten carbide hardfacing layers, further enhancing surface hardness and wear resistance.
Real cases speak for themselves:
A beneficiation plant in Sichuan processes local vanadium-titanium tailings with feed particle size ≤50mm and discharge controlled at 3–8mm. The roller shell has been in continuous use for 28 months without replacement, and the ball mill current has been significantly reduced.
An iron ore processing plant in Hebei originally used impact crushers, replacing blow bars twice a month. After switching to high-pressure roller crushers, only one routine maintenance was performed in three years, with more stable output.
In addition, the machine produces minimal over-crushing, preventing valuable minerals from being turned into slime. This preserves more coarse fractions for subsequent magnetic separation, improving recovery rate. The whole machine features a robust structure: heavy-duty frame, independent lubrication system and sealed dustproof design, suitable for 24-hour continuous operation.
Of course, to ensure optimal performance, several points should be noted:
• Control feed particle size within 5cm;
• Install an iron remover to prevent iron blocks from scratching the roller surface;
• Maintain uniform feeding to avoid idling or overloading.
Therefore, “handling 200 kinds of stone materials” is not an empty boast, but a comprehensive capability supported by reasonable structure, reliable materials and stable operation. Despite its high hardness, vanadium-titanium iron ore can be efficiently processed into qualified crushed materials by high-pressure roller sand making machines – not through brute force, but through reliable design and performance.
