The equipment can efficiently crush large pieces of metal ore raw ore and non-metallic ore into standard particle sizes, providing stable raw materials for subsequent secondary and tertiary crushing processes, and is the preferred equipment for primary crushing operations in various mines.
1.2 PYY Single-Cylinder Hydraulic Cone Crusher: Refined Secondary Crushing for Particle Size Control and Quality Improvement
After the primary crushing process, the PYY series single-cylinder hydraulic cone crusher can meet the secondary crushing needs of metal ores such as gold ore and iron ore as well as hard rock. It has the characteristics of large crushing ratio and excellent finished product particle size, which can provide uniform material sources for subsequent processing and effectively improve the concentrate recovery rate. Equipped with a conveying system, the equipment can realize automatic return circulation of unqualified materials, accurately control the discharge particle size, and improve the comprehensive utilization rate of raw ore.
1.3 PYD Multi-Cylinder Hydraulic Cone Crusher: All-Round Secondary and Tertiary Crushing with High Output and Excellent Particle Size
The PYD series multi-cylinder hydraulic cone crusher focuses on low cost, long service life and high particle size quality, and is suitable for the secondary and tertiary crushing of various materials such as gold ore, iron ore, copper ore, lead-zinc ore, limestone and basalt. Adopting laminated crushing technology, the finished product has high particle regularity, and the output and quality of fine particles are improved simultaneously, which can meet the high-standard needs of metal ore concentrate processing and high-grade aggregate production.
1.4 PF Series Impact Crusher: Versatile Secondary and Tertiary Crusher with Wide Adaptability
The PF series impact crusher is suitable for the secondary and tertiary crushing of soft and medium-hard rocks. It can flexibly adjust the configuration according to the raw material type, production scale and finished product specifications, with strong equipment adaptability. It has the advantages of large crushing ratio, low content of needle-like and flaky finished products and regular particle shape, and is widely used in sand and gravel aggregates, building materials production and other fields.
1.5 G Series High-Pressure Roller Mill: Energy-Saving and Cost-Reducing for Fine and Ultra-Fine Crushing
The G series high-pressure roller mill focuses on the fine and ultra-fine crushing links. The single-machine processing capacity can reach 80-1180 tons per hour, and the power consumption is 15%-35% lower than that of traditional crushing equipment. The roller surface is made of wear-resistant materials, and the frequency of equipment maintenance is reduced by 30%. It can stably adapt to the ultra-fine crushing of metal ores such as gold ore, iron ore, copper ore and lead-zinc ore, as well as the fine crushing of sand and gravel aggregates, realizing efficient, low-consumption and stable operation.
2. Coordinated Supporting Equipment to Open Up the Entire Production Link
Dahongli has simultaneously configured raw material pretreatment, screening, conveying, storage and transportation as well as environmental protection supporting equipment, constructing a full-process closed-loop production system to solve problems such as equipment incompatibility, process jamming and production capacity waste.
2.1 ZSW Series Vibrating Feeder: Raw Material Pretreatment with Stable Feeding
The ZSW vibrating feeder can realize uniform and quantitative feeding, and pre-screen fine materials at the same time, avoiding problems such as equipment blockage and efficiency reduction caused by uneven feeding, providing continuous and stable raw materials for the crushing link, and ensuring the smooth operation of large-scale production.
2.2 YK Series Vibrating Screen: Precise Classification to Improve Added Value
After the secondary and tertiary crushing, the materials are transported to the YK series vibrating screen by the TDY series belt conveyor. The equipment operates stably at high frequency, adopts multi-layer screen mesh for precise classification, can flexibly adjust the finished product specifications, separate multi-grade finished products, and improve product added value.
2.3 TK Series Horizontal Elliptical Screen: Efficient Screening Without Blockage and Space Saving
The TK horizontal elliptical screen is designed for high-production and easy-blocking working conditions. Adopting an elliptical movement track, it has large processing capacity, good screening effect and is not easy to block holes. The horizontal installation structure saves space, and it is specially built for high-production classification scenarios such as mines and building materials.
2.4 TDY Belt Conveyor: Efficient Conveying with Partitioned Storage and Transportation
The finished materials are transported to the finished product warehouse for partitioned storage by the TDY series belt conveyor, which is convenient for subsequent loading, unloading, transportation and sales. Cooperating with the operation of the complete set of environmental protection equipment, it realizes green, compliant and efficient production.
