什么是平面回转筛？
平面旋转筛，又称平转筛，是一种用于按粒径分离煤炭、矿石、骨料及化工粉体等散装物料的设备。广泛应用于采矿、冶金、化工及粮食加工生产线。视物料不同，处理能力可达约800吨/小时。.
该设备具有近水平筛面，并以受控的往复旋转运动运行。物料从中心进入，在筛面上铺展，并沿螺旋路径缓慢向外移动。在此过程中，细颗粒穿过筛网，而较大颗粒则向出料端移动。内置清理系统可防止筛网在运行过程中堵塞。在生产线上，通常安装于颚式破碎机或圆锥破碎机之后，用于输送或堆存前的最终分级。.
平面旋转筛工作原理
该设备 平面回转筛 （又称旋振筛或矩形分级机）利用独特的水平往复运动，实现高处理量、高精度的颗粒分离与分级。.
关键技术参数与力学特性
- 驱动机构：绕固定轴旋转的偏心轮机构。.
- 力特性：沿水平面特定方向产生的周期性交变惯性力。.
- 筛面倾角：水平或微倾斜，倾角为0°–5°。.
- 运动轨迹：可变轨迹，从进料端的侧向椭圆运动过渡至中心区域的圆周运动，最终在出料端形成直线往复运动。.
第一步：物料给入与均匀分布
物料通过进料口进入筛箱，并经过布料装置。设备启动后，驱动组件产生往复惯性力，使筛箱在水平面内做周期性运动。该运动使物料迅速在筛面全宽范围内铺展，形成薄而均匀的物料层。.
第二步：平面往复运动分层
物料层沿筛面行进时，经历定向的低频翻滚与滚动运动。水平剪切力使物料按粒径自然分层：
- 细料（筛下物）：较小颗粒迅速沉入物料层底部，接触筛网并通过筛孔落入下层。.
- 粗料（筛上物）：较大颗粒保持在物料层上表面，并向前推进至出料端。.
第三步：多层筛分与分级
对于多层配置，物料依次通过多层筛网，筛孔尺寸逐层递减：
- 顶层筛网：隔离并去除大块杂质或超大颗粒。.
- 中层筛网：分离并收集合格的目标产品。.
- 底层筛板：收集最细粉尘、细料或筛下杂质。.
第四步：物料排出
到达出料壳体后，分离后的各组分连续导入各自的出料口：
- 筛上物组分 从上出料口排出。.
- 合格产品 从中出料口排出。.
- 筛下物组分或细料 从下出料口排出。.
可变轨迹运动的优势

（铺展物料） （颗粒分层） （排出筛上物）
- 无垂直振动：近水平运动消除了垂直冲击，可保护脆性物料免受破碎，并显著降低对支撑结构的动态载荷。.
- Extended Screening Path: The combination of elliptical, circular, and linear motion paths forces particles to stay in contact with the screen mesh longer, maximizing screening efficiency and preventing mesh blinding.
优势
Planar Rotary Screen runs for stable and continuous grading of bulk materials. The structure keeps screening steady during long operation, reduces frequent adjustments, and makes daily use simpler on site.
筛分效率高
Multi-stage separation can reach up to 6 fractions. Efficiency usually stays around 90–95%, depending on the material.
Self-cleaning screen surface
Each screen layer has bouncing balls underneath. During running, the balls keep tapping the mesh, helping loosen stuck material and reduce blockage so material can pass through more smoothly.
Better screen utilization and longer mesh life
Material moves in a controlled rolling path instead of strong vibration. Contact with the screen surface is more even, so the mesh wears slower and lasts longer in real operation.
Fully enclosed operation
The machine is sealed during operation. Dust leakage is reduced, and the surrounding area stays cleaner during production.
Low maintenance
No high-frequency vibration system inside. Fewer stressed parts during running, so maintenance mostly stays on routine checking and occasional part replacement.
Easy installation and layout
Structure is modular and compact. It fits both new plants and existing production lines without major layout changes.
应用领域
Planar Rotary Screen is used for continuous particle classification and grading in industrial production lines. It provides stable separation for medium and fine materials, helping maintain consistent particle size and stable product quality in large-scale processing systems. The following are Application Industries & Materials:

Planar Rotary Screen vs Vibrating Screen
In industrial screening applications, equipment selection depends on material characteristics, capacity demand, and plant layout. Both Planar Rotary Screen and 振动筛 are widely applied in mining, aggregate, and bulk material processing systems, operating under different screening mechanisms and suitable for different working conditions. Jiarui Machinery supplies both solutions to support different production requirements.
| 项目 | 平面回转筛 | 振动筛 |
| 工作原理 | Rotating screening surface with controlled material residence time | High-frequency vibration for particle separation |
| Material Behavior | Stable rolling movement, longer screening time | Rapid vibration and particle stratification |
| Suitable Conditions | Mixed materials, moderate moisture, multi-fraction grading | Dry, free-flowing materials, simple grading |
| Feed Characteristics | Handles variable feed conditions more steadily | Requires stable and uniform feed |
| Capacity Range | 10–350 t/h (model dependent) | 20–500 t/h (configuration dependent) |
| 筛选效率 | Stable 90–95% under continuous operation | 80–90%, influenced by feed stability |
| Moisture Adaptability | Medium tolerance to moisture and stickiness | Low tolerance, higher clogging risk under wet conditions |
| 粒径范围 | Suitable for medium to fine multi-stage separation | Suitable for coarse to medium grading |
| Maintenance Demand | Low wear components, longer service interval | Regular mesh, spring, and bearing replacement required |
| Installation Requirement | Compact modular layout, flexible arrangement | Requires reinforced foundation and vibration support |
| Investment Level | 中等 | Medium to low |
| Operational Stability | More stable under variable working conditions | Best performance under stable operating conditions |
Selection Insight
For mixed materials, moderate moisture, or when multiple grading steps are needed, the Planar Rotary Screen usually performs more steadily. Vibrating screens are more commonly used for dry, stable feed with higher throughput. The final choice still depends on real material conditions and how the plant is arranged.If you are still unsure about the right selection, you can contact us for technical advice based on your material and project conditions.
