Product Overview

The hydraulic open-box sand making machine adopts the composite crushing principle of stone hitting stone and stone hitting iron, and is core equipped with one-key hydraulic open cover structure, focusing on the integrated sand making and shaping operation of medium-hard ores such as river pebbles, granite and basalt. The equipment realizes impact crushing and independent shaping of materials through high-speed rotating hammers. The finished sand has round particle shape and reasonable gradation, fully meeting the requirements of national standard manufactured sand. The hydraulic cover opening design allows the replacement of wearing parts without large hoisting equipment, greatly shortening the downtime. It is suitable for sand and gravel plants, infrastructure project sites, tailings recycling and other scenarios, with the core advantages of high sand making efficiency, convenient maintenance and excellent particle shape, and is the core sand making equipment for small and medium-sized sand and gravel production lines.

Product Advantages & Technical Highlights

Hydraulic Quick Opening: One-key hydraulic cover opening, no hoisting equipment needed for wearing parts replacement, disassembly and assembly completed in 5-10 minutes, greatly reducing downtime loss.
Excellent Particle Shape: Stone hitting stone self-shaping process, the finished sand has no needle flake shape and uniform gradation, meeting the sand use standards of high-speed rail, municipal administration, real estate and other scenarios.
Wear Resistant: Hammers and liners are made of high chromium alloy wear-resistant material, with strong impact and wear resistance, greatly improving the service life of wearing parts.
High Efficiency Sand Making: Optimized crushing cavity design, sufficient material crushing without blockage, integrated sand making and shaping, fine crushing and sand making can be completed with a single machine.
Flexible Adaptation: The discharge gap can be accurately adjusted to adapt to the demand of manufactured sand with different specifications of 0-5mm, and even beginners can operate it quickly.

Applicable Scenarios & Materials

Sand and gravel production plant: Sand making from river pebbles, granite, basalt, limestone and other raw materials, mass production of high-quality national standard manufactured sand.
