Reversible Sand Making Machine (PCKW Series)
No-grate design · Reversible rotor · 0-10mm output · Wet & dry materials
The Reversible Sand Making Machine is a next-generation, no-grate sand maker professionally engineered by Hengtai Global. It resolves the clogging problem caused by high moisture content in river pebbles and cobblestones, making it highly efficient for both dry and wet materials.
Equipped with a reversible rotor, the machine allows the blow bars and impact plates to wear evenly on both sides through a simple reverse switch. This design reduces downtime, extends the service life of wear parts, and ensures an exceptional, uniform output size for sand and fine aggregates.
It serves as primary fine-crushing equipment for metallurgy, construction materials, chemical industries, hydropower projects, and other aggregate production lines.

Outstanding Advantages
Low Energy & High Yield: Optimized single-motor drive consumes lower power while delivering strong output, with the finished product rate reaching approximately 80%.
No-Grate Design: Eliminates traditional grate screen bars and handles high-moisture and sticky materials without clogging.
Reversible Rotor Technology: Dual-direction rotation ensures symmetric wear of hammers, extending service life and reducing replacement frequency.
Hydraulic Open-Top System: The hydraulic cover opening mechanism allows fast, safe, and labor-saving replacement of wear parts.
How It Works
The electric motor drives the rotor to rotate at high speed through the V-belts, creating the core impact force of the crusher.
Material entering the crushing chamber is first impacted and shattered by the fast-spinning blow bars, then projected against the impact plates for secondary reduction.
The material undergoes repeated high-frequency impacts until it becomes smaller than the preset clearance gap and is discharged smoothly from the bottom.

Competitive Edge vs. Traditional VSI Crushers
Hard Rock Specialist with High Efficiency: For hard materials such as basalt and granite, the heavy-duty rotor delivers strong impact force and high capacity. The reversible utilization rate of blow bars reaches 90%, helping reduce annual parts cost.
Single-Motor Eco-Drive: Compared with traditional vertical shaft impact crushers that often require dual high-power motors, the PCKW reversible sand maker achieves strong throughput with a single-motor system, reducing power consumption.
Advanced Intelligent Lubrication: A centralized oil-circulation station provides automatic lubrication, ensuring balanced transmission, sensitive action, and high load-bearing capacity.

Frequently Asked Questions
It is highly suitable for medium-hard to high-hardness materials including river pebble, granite, basalt, limestone, quartz sand, iron ore, and construction waste. It performs exceptionally well with high-moisture materials.
No, absolutely not. The no-grate-bar design completely overcomes the sticky clogging issues common in traditional crushers, allowing both bone-dry and soaking-wet materials to pass smoothly.
The output size can be adjusted by altering the gap between the blow bars and the impact plate. It can be controlled within 0-10mm, with fine materials making up a high proportion of production.
Yes. The machine features a hydraulic auto-top system that opens the back cover effortlessly, making it easy to inspect or replace blow bars and liners while saving labor time and safety costs.
