Complete sets of sand making and gravel crushing equipment are core equipment for the production of artificial sand and aggregates. Through an integrated crushing, sand making, and screening process, they process various natural ores and rocks into sand and gravel materials that meet construction standards, making them the main source of manufactured sand for the current engineering construction field. A complete sand production line typically includes core main equipment such as jaw crushers, impact crushers, cone crushers, and vertical shaft impact crushers, supplemented by auxiliary equipment such as vibrating feeders, vibrating screens, and belt conveyors, forming a complete production process.

 

 

Introduction to Complete Sets of Sand Making and Gravel Crushing Equipment

 

1. JC Jaw Crusher

 

As the "first stage" of the production line, it is mainly used for coarse crushing. It adopts a deep cavity crushing design and a split frame structure, with a maximum feed size of 1300mm and a processing capacity covering 50-2000t/h. It is especially suitable for the primary crushing of hard materials such as granite and basalt. This equipment is equipped with a heavy-duty moving jaw assembly and large-size bearings, offering strong impact resistance. The discharge particle size can be quickly and accurately adjusted via a mechanical or hydraulic discharge port adjustment device, significantly reducing downtime for adjustment.

 

2. PFQ Impact Crusher

 

Impact crushers are generally used for medium-scale crushing of materials. They feature a unique three-stage crushing chamber (P coarse crushing zone, S medium crushing zone, T fine crushing zone), with hourly processing capacities ranging from 50 to 1000 tons. Suitable for processing medium-to-low hardness materials such as limestone and dolomite. The equipment uses high-chromium hammer plates and toothed impact liners, increasing crushing efficiency by 15%-20% compared to traditional impact crushers. The crushed material is mostly cubic, meeting the requirements for artificial sand and gravel, making it particularly suitable for highway and high-speed rail projects with high requirements for aggregate particle shape.

 

3. HPY Multi-cylinder Hydraulic Cone Crusher

 

Targeting the medium-to-fine crushing needs of high-hardness materials, it adopts a layered crushing principle, combined with a large eccentricity and high swing frequency design. The maximum production capacity can reach 3035 t/h, producing uniform and rounded discharge particles. This equipment is equipped with an advanced hydraulic protection system, enabling automatic release of excess iron and hydraulic clearing of the chamber, effectively reducing equipment failure rate and worker labor intensity. Its fixed-axis design and integrated steel frame structure further enhance stability and service life, making it one of the core pieces of equipment in large-scale sand and gravel aggregate production lines.

 

4. PLS Vertical Impact Crusher (Sand Making Machine)

 

As the "core protagonist" in the sand making process, it offers two crushing modes: "stone-on-stone" and "stone-on-iron," which can be flexibly switched according to material hardness. Through optimized rotor structure and crushing speed, the equipment achieves sand making efficiency more than 20% higher than similar products, producing finished sand with reasonable gradation and excellent particle shape, particularly suitable for artificial sand making from hard rocks such as granite and basalt. This model can also be equipped with a thin oil lubrication system and a PLC automatic control system to monitor equipment operation status in real time and achieve intelligent production.

 

From a market price perspective, the price range of complete sand making and crushing machines is quite large, mainly depending on the production line's capacity, equipment configuration, and material characteristics. Small-scale basic production lines (30-50 tons per hour) typically cost between $20,000 and $50,000; medium-sized standard production lines (50-100 tons per hour) cost approximately $80,000 to $150,000; while large-scale intelligent production lines (over 100 tons per hour) can cost $150,000 to $1.5 million or even higher. Prices vary between manufacturers due to differences in technology, materials, and after-sales service. It is recommended that companies comprehensively consider factors such as equipment performance, energy consumption, and maintenance costs when purchasing to choose a cost-effective solution.
