Manufactured Sand / Dry Process
Dry-process manufactured sand and aggregate line for low-mud stone materials, built around feeding, crushing, screening and conveying.
Equipment matching is checked by feed material, mud and moisture, target capacity, product size, site layout and environmental requirements.
This line is a dry-process solution for customers who need manufactured sand and graded aggregate without a washing section. It is mainly selected when the raw material is relatively clean, dry and suitable for dry screening.
For high-mud material, strict sand cleanliness targets or wastewater recycling requirements, the washed sand production line should be discussed instead.
Feed raw stone into the crushing line steadily; use grizzly pre-screening when raw stone is large or contains more fines.
GZT grizzly feeder or ZSW / GZD vibrating feeder
Reduce large raw material to a size suitable for secondary crushing.
WLC jaw crusher
Crush and shape material according to hardness and finished sand requirement.
PCZ heavy hammer crusher or SHKX reversible fine crusher
Separate manufactured sand and aggregate sizes; return oversize material if needed.
Inclined vibrating screen or horizontal screen
Send oversized screen material back to the crushing section to stabilize finished product grading.
Return belt conveyor + secondary / fine crushing equipment
Connect sections and stockpile finished products.
WLB belt conveyor
Reduce dust from crushing, screening and transfer points according to site environmental requirements.
Spray dust suppression, enclosed transfer points or dust-collection system
| Process role | Equipment reference | Selection note |
|---|---|---|
| Feeding | Feeding Equipment | Use vibrating feeder for steady dry material feeding; grizzly feeder can be discussed when raw stone is larger or contains fines. |
| Primary crushing | WLC Jaw Crusher | Used as the first crushing section for larger raw stone. |
| Medium-soft secondary crushing | Heavy Hammer Crusher / Roller Crusher | Limestone, bluestone and other medium-low hardness brittle materials can use heavy hammer crusher or roller crusher. |
| Hard-rock secondary crushing | Hydraulic Cone Crusher | Granite, basalt, river pebble and other hard or abrasive materials should be evaluated with cone crushing. |
| Fine crushing and shaping | SHKX European Reversible Fine Crusher | Used for dry premium manufactured sand shaping and 0-5 mm fine control; not for large-block primary crushing. |
| Screening | Vibrating Screen | Multi-deck screens separate finished sand and aggregate grades. |
| Conveying | WLB Belt Conveyor | Transfers material between crushing, screening and finished stockpile sections. |
| Process section | Standard equipment | Optional equipment |
|---|---|---|
| Feeding | ZSW / GZD vibrating feeder. | Use GZT grizzly feeder when raw stone is large or contains many fines. |
| Coarse crushing | WLC jaw crusher. | When feed size is smaller and material hardness is medium-low, a simplified coarse-crushing configuration can be discussed. |
| Secondary / fine crushing | Select heavy hammer crusher, roller crusher, hydraulic cone crusher or SHKX fine crusher by material and product target. | Add SHKX shaping or cone crushing when premium sand shape or aggregate shape is required. |
| Screening | Inclined vibrating screen or horizontal screen. | Horizontal screen is preferred for high-precision dry sand grading; inclined screen is preferred for coarse aggregate grading. |
| Return material | Oversize return belt conveyor. | Add transfer hopper or speed-adjustable conveyor according to closed-circuit ratio and capacity target. |
| Dust control | Spray dust suppression or enclosed transfer points. | For strict environmental requirements, discuss baghouse dust collector, sealed belt conveyors and enclosed workshop. |
| Finished stockpiling | WLB finished product belt conveyor. | Add multiple stockpile conveyors, silo or loading system according to finished product sizes. |
The following packages are early planning references, not guaranteed output. Actual capacity depends on stone hardness, moisture, feed grading and closed-circuit ratio.
| Line size | Typical capacity target | Configuration idea |
|---|---|---|
| Small line | 50-100 t/h | ZSW380x95 feeder + WL80 jaw crusher + PCZ1008 heavy hammer crusher + 1230 vibrating screen. |
| Medium line | 100-200 t/h | ZSW490x110 feeder + WL110 jaw crusher + PCZ1310 heavy hammer crusher + 1548 three-deck vibrating screen. |
| Large line | 200-300 t/h | ZSW490x130 feeder + WL140 jaw crusher + SHKX1600 fine crusher + 1860 horizontal fine screen. |
The following package configurations are for website communication only. Formal proposals must be reviewed by hardness, mud and moisture content, screen openings, closed-circuit ratio and dust-control requirements.
Medium-low hardness brittle materials such as limestone and bluestone, mainly producing ordinary sand and stone material.
About 50-150 t/h
Use screening and return material to stabilize 0-5 mm manufactured sand and multiple aggregate grades.
About 100-250 t/h
Granite, basalt, river pebble and other abrasive hard rock where wear-part cost must be controlled.
About 150-300 t/h
Use a dry route when the raw stone is relatively clean, mud content is low, water supply is limited and the target product does not require wet washing. If cleanliness or fine-mud removal is critical, compare it with the washed sand production line.
The crusher depends on hardness and target size. Heavy hammer crusher or roller crusher can be discussed for suitable medium-soft material, while hard rock should be checked with hydraulic cone crushing and fine shaping.
Feed grading, crusher selection, closed-circuit vibrating screen setup, powder control and dust collection all affect finished sand grading, powder content and particle shape.
