50-80-T/H Stone Crushing Plant Overview
This 50-80-T/H Stone Crushing Plant scheme designed by Sandreck Mining Machinery is tailor-made for small and medium-sized sand and gravel plants, stone processing, and construction waste recycling projects. Under standard conditions with raw material moisture ≤8%, the maximum production capacity can reach 85 tons per hour.
Conventional Aggregate Specifications: 0-5mm, 5-10mm, 10-20mm, 20-31.5mm, etc.
High-hardness Rocks: such as granite, basalt, pebbles, iron ore, limestone, etc.
Medium to Low Hardness Materials: such as coal gangue, shale, tailings, construction waste concrete, bricks, etc.
Core Equipment Configuration for the 50 T/H Stone Crushing Plant
Feeding:
GZD9638 vibrating feeder (1 unit) – pre-screening and soil removal, uniform feeding.
Primary crushing: PEV500×750 Jaw Crusher (1 unit) – provides stable primary crushing for the entire line.
Secondary medium/fine crushing: PF1210 Impact Crusher (1 unit) – excellent product particle shape, suitable for most materials.
(For high-hardness rocks like granite or basalt, it can be replaced with an HST100 Cone Crusher for stronger wear resistance and lower operating costs.)
Screening and grading: 3YZS1860 triple-layer circular vibrating screen (1 unit) – efficient and precise screening.
Conveying: Customized belt conveyors (5–6 units) – connecting each process step.
Value-added options:
For producing manufactured sand, add a VSI7615 sand-making machine.
For high-standard clean aggregates, add a sand washer.
For construction waste processing, add iron removers at the entrance of each equipment unit.
How the 50 T/H Stone Crushing Plant Works
The entire stone crushing line adopts automated production with minimal labor requirements, ensuring smooth operation:
Feeding and coarse crushing: Raw materials are evenly fed into the Jaw Crusher via the vibrating feeder for initial crushing, producing aggregates <150mm.
Fine crushing and shaping: The coarsely crushed materials enter the Impact Crusher (or Cone Crusher for hard rocks) for secondary crushing and shaping, producing aggregates ≤40mm.
Screening: The crushed materials are precisely screened by the multi-layer vibrating screen. Qualified finished products are directly sent to storage, while unqualified aggregates are returned to the Impact Crusher or Cone Crusher for re-crushing, forming a closed-loop cycle.
Optional washing: If needed, the screened finished products can be washed in a sand washer to obtain high-purity aggregates.

Case Studies
Case 1: Limestone Sand-Making Production Line in Sichuan, China, with an Hourly Output of Approximately 70 Tons
Project Overview: The raw material is limestone, with a feed size of ≤210mm. The required finished product is 0-5mm sand, with an hourly output of approximately 75 tons.
Equipment Configuration: PE250×1200 Jaw Crusher ×2 + PF11214 Impact Crusher + VSI7615 Sand-Making Machine + 2YK2160 Vibrating Screen + XSD2610 Sand Washer + Multiple Conveyors.
Process Features:
1.Utilizing the site’s elevation differences, a modular design was adopted to rationally layout the production line.
2.The VSI Crusher is recommended as the sand-making machine, producing sand with an aesthetically pleasing grain shape.
Case 2: Granite Crushing and Sand-Making Production Line in Indonesia, Southeast Asia
Project Overview: The raw material is granite, with a feed size of ≤280mm. The stable hourly output is 50-80 tons, producing 0-5mm manufactured sand, 5-12mm, and 12-25mm aggregates, which must meet local infrastructure material standards.
Equipment Configuration: PE57 Jaw Crusher + HST100 Cone Crusher + 2YK1860 Vibrating Screen + Sand Washer + Conveyors.
Process Features and Advantages:
1.Due to site constraints, a Mobile Crushing Station was used, requiring minimal foundation work and facilitating easy relocation.
2.For high-hardness granite, the combination of a Jaw Crusher and a Cone Crusher is recommended, offering high crushing efficiency and low operating costs.
3.The inclusion of a sand washer ensures the finished product has a mud content of ≤1% after cleaning, meeting the requirements for construction sand.
Case 3: Limestone Aggregate Crushing Production Line in Ghana, Africa
Project Overview: The raw material is limestone rock, with a feed particle size of ≤350mm. There is no sand-making requirement. The stable hourly output after commissioning is 60-80 tons.
The finished products are three types of crushed stone aggregates: 5-10mm, 10-20mm, and 20-30mm, supplied directly to local municipal road and commercial housing construction projects.
Equipment Configuration: PE250×1000 Fine Jaw Crusher + CS600 Cone Crusher + 2YK1860 Vibrating Screen + 5 units of B650 Belt Conveyors.
Process Features:
1.The combination of a Jaw Crusher and a Cone Crusher is well-suited to the characteristics of limestone, providing a high crushing ratio and uniform output.
The dry screening process requires no water washing, making it suitable for the arid climate of Africa.
