Product Description

Product Description
The VSI series vertical shaft impact crusher, a state-of-the-art sand-making machine, stands as the pinnacle of advanced technology integration, crafted by Shanghai Luqiao Mining Machinery Co., Ltd. This third-generation, high-efficiency marvel distinguishes itself with international-grade, high-performance capabilities for both sand making and stone shaping. Its unrivaled prowess in the fine crushing of diverse materials has earned it the esteemed status of the go-to equipment for manual sand making and stone forming applications. Ideally suited for medium and fine crushing tasks, it excels with ultra-hard and medium-hard materials, ranging from refractory substances and aluminum-vanadium soil clinker to glass raw materials and metallurgical slags. Its versatility extends across materials like quartz stone, river pebbles, iron and copper ores, granite, limestone, and construction sand, making it indispensable in modern industry.
Working Principle
The vertical axis impact crusher operates on a sophisticated mechanism where the material is propelled from the impeller at a rapid velocity of 60-100m/S, driven by centrifugal force. This dynamic interaction results in a significant collision with both freely-falling material and the material lining. The material then ascends the sloped accumulation, turning downward to collide again with impeller-ejected material, ensuring thorough impact, grinding, and crushing. The cycle concludes with energy-depleted material exiting through the discharge silo, achieving optimal processing.
Equipment Characteristics and Advantages
Embrace the design ethos of stone ----The machine boasts a simplistic structure, delivering an exceptional sand formation rate while maintaining low operational costs. This translates into significantly reduced wear and minimized maintenance needs.
Large Processing Capacity ----Experience a remarkable 30% increase in output compared to traditional equipment, powered by enhanced wire speed under equivalent power. The result is an abundance of fine materials with consistent stability.
Adjustable Central Feed ----Hydraulic adjustments of feed size offer precise control over motor current, ensuring the motor runs at peak efficiency.
Superior Grain Shape----Achieve products with optimal cubic form, minimal needle content, and outstanding shaping precision. The fineness modulus is easily adjustable to meet specific needs.
Thin Oil Lubrication System----Benefit from fully automatic control and protection features, including alerts for oil pump and host overloads, and ultra-high oil temperature shutdowns. The system also automates cooling and heating based on oil temperature.
Easy Maintenance with Hydraulic Device----The hydraulic lid opening and belt adjustment system simplify maintenance, disassembly, and replacement tasks, significantly reducing downtime and enhancing operational efficiency.
