Case Study: The MES 2260 Triaxial Horizontal Vibrating Screen Supports a Brazilian Granite Project, A Perfect Blend of 800 TPH Capacity and Extreme Energy Saving

Project Overview

• Project Location: A large granite mine and aggregate processing base in Brazil

• Application Scenarios: Providing high-quality granite manufactured sand, crushed stone, and ballast aggregate for infrastructure construction in Brazil and surrounding areas. Faced with the hardness of granite and the massive daily material throughput, traditional inclined vibrating screens can no longer meet the dual demands of high production capacity and low energy consumption.

• Core equipment: Mei Shuo 2260 intelligent three-axis horizontal vibrating screen (modular design)

Challenges and Solutions

1. The challenge of grading hard granite due to massive production capacity demand.

• Challenges: This project requires a single-line output of over 800 tons per hour and precise grading of complex granite ore with extremely high hardness and mud content. Traditional equipment is prone to clogging, severely limiting production capacity.

• Solution: The solution utilizes the Meishuo 2260 triaxial horizontal vibrating screen. This equipment uses three sets of vibrators as the excitation source to generate a high-energy elliptical motion trajectory. This motion method, combining circular vibration of loose materials with linear vibration for efficient screening, increases the throughput of equipment with the same screen size by 1 to 3 times. Simultaneously, the powerful elliptical throwing force effectively shakes off soil and impurities covering the granite aggregate, ensuring that even with a high production capacity of 800 tons/hour, the finished product maintains extremely high cleanliness and consistency.

2. Solving the "electricity hog" problem and responding to the call for green mining construction.

• Challenges: As an ultra-large production line operating around the clock, traditional heavy-duty vibrating screens consume an astonishing amount of electricity, and the high electricity costs have become a core pain point that erodes corporate profits.

• Solution: The MISHO 2260 employs innovative hybrid synchronous direct drive technology for the vibrator, eliminating the traditional gear meshing and synchronous belt external drive method. Combined with more scientific mechanical principles, this equipment successfully saves over 30% of kinetic energy consumption. This not only significantly reduces the motor load but also saves the entire production line considerable annual electricity costs, perfectly aligning with the global sustainable development goals of green mines.

3. The demand for "maintenance-free" operation and space optimization under harsh working conditions

• Challenges include: continuous high-intensity operation makes equipment bearings prone to overheating and lubricating oil prone to leakage; frequent shutdowns for maintenance not only increase labor costs but also severely slow down project progress; in addition, overseas factory construction often faces site planning restrictions.

• Solution: Thanks to its minimalist structural design without external gears and belts, the equipment completely eliminates the potential for malfunctions associated with mechanical forced synchronization devices, fundamentally eliminating oil leakage problems. Combined with fully riveted crossbeams (without any welding) and fatigue-resistant design using special materials for the side plates, the overall service life is more than three times longer than traditional screening machines. In daily operation, apart from periodic lubrication oil changes, virtually no additional maintenance is required, truly achieving a "foolproof" maintenance-free and stable operation. Furthermore, the equipment adopts a 0-angle horizontal installation, resulting in a low center of gravity and compact structure, greatly saving floor space and making it highly suitable for the modular process optimization of modern sand and gravel plants.

Operational results evaluation

• "Since introducing this Meishuo 2260 three-axis horizontal screen, our production efficiency has seen a qualitative leap. What surprised us most was its energy-saving capability and extremely low failure rate. In the past, we had to spend a lot of energy every month repairing belts and replacing bearings, but now we hardly have to worry about it. Moreover, its horizontal placement design has saved us a lot of valuable factory space, and the savings in electricity and maintenance costs have greatly improved the overall profitability of the project."

Why can this configuration create such great value?

1. Powerful performance: The excitation force generated by the three-axis forced synchronization of the Meishuo 2260 is 2.5 times that of ordinary circular vibrating screens, and it is designed for ultra-large processing capacity of 800 tons.

2. Compact structure: The horizontal layout design has a low center of gravity and a small footprint, making it extremely suitable for the modular process optimization of modern large-scale sand and gravel plants.

3. Intelligent support: Relying on the industrial internet big data platform, the system can monitor the health status of equipment in real time and provide early warnings of potential faults, transforming "passive maintenance" into "proactive prevention" and further consolidating the operation advantage of maintenance-free operation.
