The 5X Series Sand Making Machine was developed to improve energy utilization, reduce the wear rate, extend the maintenance cycle, decrease maintenance time, enhance crushing efficiency, and elevate the control level. It is a new generation sand making machine characterized by energy efficiency, high output, high energy utilization, excellent product particle shape, convenient maintenance and overhaul, and wide application, meeting the needs of modern sand and aggregate production.
Application Fields:
Sand and gravel pits, concrete sand production, dry-mixed mortar, manufactured sand, power plant desulfurization, quartz sand, etc.
Applicable Materials:
River pebbles, granite, basalt, iron ore, limestone, calcite, quartz, diabase, etc.
Working Principle:
Material enters the sand making machine through the feed hopper and is divided into two parts by the distributor. One part enters the high-speed rotating impeller through the center of the distributor, where it is rapidly accelerated—with an acceleration reaching hundreds of times the acceleration of gravity. It is then ejected from the three evenly distributed flow channels of the impeller at a speed of $60 \text{ to } 70 \text{ m/s}$. It first impacts the material liner in the vortex crushing chamber, is rebounded by the material liner, and impacts the top of the vortex chamber diagonally upwards. It then changes its direction of motion and deflects downwards, forming a continuous material curtain with the material ejected from the impeller channels. In this way, a single piece of material is subjected to two or more impacts, friction, and grinding actions within the vortex crushing chamber. The crushed material is discharged from the lower discharge opening. Throughout the entire crushing process, the material impacts and crushes itself without direct contact with metal components. Instead, the crushing and pulverizing occurs through impact and friction with the material liner, which reduces angle contamination and extends the service life of the mechanical wear parts. The clever self-circulation of the airflow inside the vortex chamber eliminates dust pollution.
Product Features:
- Unique Feeding and Crushing Methods:Full central feeding + “rock-on-rock” / “rock-on-iron” crushing, or central feeding with cascade material + “rock-on-rock” / “rock-on-iron” crushing. It abandons the traditional method of crushing material with metal components, instead utilizing the self-friction and crushing of high-speed moving materials.
- Optimized Design for High Efficiency and Large Output: The optimized launching port structure and the smooth material flow curve design inside the impeller reduce material flow resistance, increase material throughput and crushing ratio, resulting in higher efficiency, better particle shape, greater output, and lower maintenance costs.
- Quality Upgrade for Improved Overall Performance:The machine frame adopts a new hot-riveting process to enhance structural strength and toughness. The exterior features automotive-grade sandblasting and rust removal treatment, followed by a painting process, achieving a comprehensive upgrade in internal quality and external finish. Components are made of high-quality wear-resistant materials such as high-chrome cast iron and high-manganese steel, improving the overall performance of the equipment and reducing the failure rate.
- Reliable Dual-Pump Oil Lubrication System:The dual oil pump complementary system ensures oil supply, and the machine can automatically shut down if there is no oil flow or oil pressure, making it safe and reliable. The use of a thin oil lubrication system also reduces bearing friction and increases bearing speed, thereby greatly improving work efficiency.
