A clearer idea of industrial equipment
Ease Sieve is how we make engineering easier to live with.
Since Sanyuantang began making screening equipment, we have believed that a strong machine should do more than work hard. It should be clear to operate, practical to maintain and considerate of the environment around it.

Where the idea began
One principle, carried through every project
Ease · Sieve is the design philosophy shaped by Mr. Zheng Quanfa, Sanyuantang’s general manager and chief engineer.
He saw that the best screening equipment is not defined by complexity. It is defined by how confidently people can use it every day: stable motion, sensible access, controlled dust, low noise and a structure that remains dependable after years of production.
That belief became the thread connecting our machines, our production lines and the way we work with customers.
The Ease Sieve standard
Less friction. More dependable production.
We turn a simple idea into decisions that can be seen, tested and maintained.
Simple to understand
Clear layouts and practical controls help operators work with the equipment from the first shift.
Simple to keep running
Accessible components and considered structure make inspection, cleaning and service more straightforward.
Simple to improve
Lower noise, better sealing and efficient operation reduce the hidden cost of production.
How our capability evolved
A long-term commitment to useful innovation
The story of Ease Sieve is also the story of Sanyuantang growing with real production needs.
Manufacturing begins
Sanyuantang enters machinery manufacturing and starts building experience around industrial screening.
Quality becomes a system
ISO 9001 certification brings a more disciplined approach to process control and quality management.
Screening architecture advances
Independent development of square gyratory screens and structural improvements expands our application range.
Ease · Sieve in practice
The concept becomes a shared standard for clearer operation, easier service and better environmental control.
Proof in the product
Engineering ideas become real equipment
Ease Sieve is not a slogan placed after the design. It is built into the decisions that shape each machine.
Rotary vibrating screen
A one-piece stamped chassis and upper cover support stable operation while helping reduce noise and simplify day-to-day use.
Square gyratory screen
Reinforced structure and a carefully arranged internal path deliver high output with durable, energy-conscious performance.
Beyond one machine
Ease also belongs in the production line
When the challenge is a complete process, the same thinking guides the layout from feeding to finished material.
For dust-free feeding, closed conveying and efficient dust collection help keep material transfer cleaner and safer. For sand production, energy-conscious crushing, screening and sensible material flow help reduce handling, storage and avoidable waste.
In both cases, the goal is the same: a line that is easier to understand, easier to control and easier to improve.

“Ease Sieve is our promise to remove unnecessary difficulty from industrial production—through the machine, the process and the support that follows.”
— Zheng Quanfa · General Manager & Chief Engineer
