Crushing Solution for Mining and Hard Rock - MP Mining
Case detail

MP Mining Equipment has built 15 years of solid experience in crushing technology. It manufactures a complete line of crushers, screens, feeders and sand makers, along with full supporting parts, boasting more than 200 models in total. Tailored for various site conditions, three crushing line types — fixed hard rock lines, fixed medium-hard rock lines and mobile lines — are introduced below, covering relevant processes and standard equipment packages.

1. Fixed Crushing Line for High-Hardness Rock

This plant processes granite, basalt and natural cobblestones.

MaterialCompressive StrengthCharacteristic
Granite, basalt, natural cobblestones200 – 350 MPaHigh silicon content, strong abrasiveness

These materials work as ideal raw materials for premium construction aggregates.Most operators select fixed plants for long-term production. Main products include 0–31.5mm aggregates and 0–5mm manufactured sand. Operators expect over ten years of steady continuous operation, so equipment durability and running costs stand as core concerns.High-hardness rock crushing faces three common operational challenges. Liners wear rapidly when processing tough, abrasive rock. Frequent shutdowns for part replacement raise costs and interrupt production. Liners are engineered for a minimum service life of 2,000 working hours.Poor particle shape will fail international aggregate specifications.

StandardFlaky Particle LimitApplication
ASTM C33 / EN 12620Below 10%High-grade construction aggregates
ASTM C33 / EN 12620Over 15%Road base materials only

Excessive flaky particles will lead to a notable drop in project revenue.Hard rock crushing consumes far more power than soft rock processing. Its power use is 1.5 to 2 times higher, and excessive electricity costs will undermine overall project profitability.MP Mining Equipment adopts a proven four-stage crushing and screening process. Core units apply the reliable interparticle crushing principle. CC and MHP hydraulic cone crushers act as key processing equipment, while PEV/PEW jaw crushers and YK screens form the complete production line.VSI vertical shaft impactors are installed for particle shaping and sand production. XSH or TSS units undertake sand washing and fine sand recovery work.MHP multi-cylinder cone crushers produce well-shaped cubic particles. A fixed discharge opening ensures consistent material sizing. Built-in hydraulic cylinders automatically remove tramp iron during operation. Hydraulic motors enable quick gap adjustment and liner replacement.

Bronze bushings deliver high load capacity and low maintenance. All components are accessible from both top and side positions for easy servicing.CC single-cylinder cone crushers are equipped with CLP constant crushing chambers. They offer high throughput and reliable automatic overload protection. Low power consumption makes these units highly energy-efficient.

MP Mining Equipment configures equipment according to hourly production capacity.

Hourly CapacityProduction Package
≤ 150t/hStandard set
150 – 250t/hMedium-capacity set
300 – 350t/hLarge-capacity set
500t/h and aboveSuper large-capacity set

Ready-to-use packages cover all the above mainstream capacity ranges.The full equipment set effectively addresses the three major operational challenges.

Performance ItemTechnical Improvement
Liner service lifeDoubled via interparticle crushing
Wear resistance of mantles & concavesIncreased by over 15% (high-manganese alloy steel)
Service life of wear parts3 times longer than standard components
Flaky particle contentControlled below 8%
Power consumption4.5 – 5.5 kWh per ton of processed rock

The combined crushing system keeps flaky particles below 8%, and finished products fully meet the standards for high-grade concrete.PLC automatic systems adjust feed volume and crusher discharge openings. They prevent equipment idling and unexpected overloads. Power consumption is maintained at 4.5–5.5 kWh per ton of processed rock.

2. Fixed Crushing Line for Medium-Hardness Rock

This plant is designed for tuff, diorite and other medium-hard rock.

MaterialCompressive StrengthTarget Users
Tuff, diorite and similar rock150 – 200 MPaSmall mine owners, new industry practitioners

Operators balance upfront costs and total equipment service life. Stable operation over ten years or longer is also a basic requirement.Equipment selection is the top concern for most potential buyers. Many struggle to pick between cone crushers and impact crushers. Clients compare total costs over the full equipment service lifecycle.Users worry about performance drops after years of continuous use. Rock hardness often varies across different zones within one mine. Many fear units cannot process occasional sections of harder rock.

MP Mining Equipment provides two practical solutions for different needs.

SolutionCore EquipmentAdvantagesSuitable Scenarios
Solution 1Cone crusher + Jaw crusher + Vibrating screenLow running cost, long-lasting wear partsLong-term operation, variable rock hardness
Solution 2PFC impact crusherLow initial investment, excellent particle shapeShort-term projects, limited budgets

PFC impact crushers feature sturdy, field-tested mechanical structures. Wedge blocks secure blow bars firmly to avoid component damage. High-chromium cast iron further extends the life of wear parts.One hydraulic system controls frame access and discharge openings. Side service doors simplify inspections and blow bar replacements. Interchangeable parts cut down clients’ spare parts stock needs. Safety sensors stop accidental startup during maintenance work.Optional parts include hydraulic regulators and third impact plates. Multiple wear materials adapt the unit to various working conditions.MP Mining Equipment shares practical tips for equipment selection. Cone crushers are recommended for projects planned for 10+ years of operation, as they maintain stable performance far better than impact crushers.Impact crushers suit short-term projects or projects with limited budgets, delivering qualified materials with minimal upfront spending.Cone crushers are ideal when rock hardness changes frequently for strong adaptability. Impact crushers wear rapidly when processing extra hard rock.

3. Mobile Crushing Line

MP Mining Equipment offers two types of mobile crushing plants.

Plant TypeProduction SourceRelocation TimeRecommended Application
Tire-mounted plantSelf-manufactured1 – 2 working daysOccasional moves, paved surfaces
Crawler-mounted plantPartner-supplied2 – 3 working daysFrequent moves, rough terrains

Mobile plants suit mines with an operating life under five years. They also work for road construction and temporary material yards. Units need to move regularly to follow active work areas on site. Operators prioritize fast startup and simple relocation procedures. Mobile plants require no complicated concrete foundation work. Installation time is cut by around 80%.Three key factors guide clients when choosing mobile equipment. Reliable units avoid costly delays to construction schedules. Relocation time and supporting tools are also major considerations.Mobile plants adopt the same core machinery as fixed crushing lines. Every mobile unit completes no-load testing before delivery. Full operation manuals are supplied with all finished equipment.The product lineup includes mobile jaw, cone and standalone screen plants. Mobile crushing systems cover capacities from 50t/h to 300t/h.Crawler units are preferred for frequent moves and rough, uneven terrain. Tire-mounted units are more cost-effective for occasional moves on paved surfaces with available tractors.Standard operation and maintenance ensure long stable performance.

Maintenance ItemInspection CycleHandling Standard
Liner wear checkMonthlyReplace when wear reaches 30% of original thickness
Oil temperature, pressure & quality checkWeeklyKeep indicators within normal range
Cone crusher lubricant replacementEvery 6 monthsComplete oil change
Hydraulic pipeline inspectionWeeklyRepair leaks immediately

Advanced seals on CC crushers effectively block outside dust. Built-in systems track liner wear for timely part replacements.Pulse bag dust collectors reach 99 percent dust collection efficiency. Enclosed hoods on screens prevent dust from spreading outdoors.MP Mining Equipment delivers full EPC contracting and plant operation. Intelligent control systems manage the entire production workflow. Professional teams handle daily operations to save time and effort.Custom crushing solutions are available from the professional engineering team. Tailored equipment setups can be designed to fit specific site conditions.
