线性运动筛分机

筛得力线性运动筛分机属于自由振动的筛分机，其振幅可自由调节，以适应筛箱和不平衡块的质量比。所设计的线性运动筛分机可选择性地采用陡角（大约75°）或浅倾角（大约40°），因此，我们可灵活选择筛板的倾斜度，其倾斜范围从向上至水平再到向下。例如，脱水筛需要向上倾斜3至5度，而分类筛分机需要向下倾斜高达约40°（薄层筛分）。

HG（双不平衡齿轮组）、DWS（双轴筛）和HR（不平衡电机）系列筛分机的分离尺寸在0.5至300mm之间，筛分面积在大约0.1至60m²之间。根据所用产品的不同，这些机器的振动幅度可在2到14mm之间进行设置。筛网装置可由一至三个筛面组成。

该线性运动筛分机的速度和振动幅度可根据产品的具体情况进行调整，从而确保获得持久完美的筛分结果。

筛箱可选用纵向或横向张紧的筛板，或适用水平筛面，也可适用第三方制造商生产的筛网。

由侧壁和横梁组成的筛箱能够承受所有的静态和动态力。振动产生系统不在筛箱的重心位置上。双不平衡齿轮组或不平衡电机安装在驱动桥上。重要的是，其合力的方向穿过重心。这同样适用于双轴筛分机上两个驱动轴的位置。

线性运动筛分机由具有中间传动的三角皮带传动所驱动，或通过万向节轴的直接传动所驱动。双不平衡齿轮组有一个注油口。不平衡电机始终采用油脂润滑。双轴筛网可选择使用油润滑或油脂润滑。

筛箱由4个弹簧元件弹性支撑在底座上。在这里，螺旋压缩弹簧、橡胶缓冲器、振动元件或风箱的不同系统均是可用的，并且如有需要，可以组合应用（混合式悬挂）。

对于含尘物料，我们可根据需要提供带有防尘罩或封闭式防尘箱的线性运动筛分机。也可采用搅打装置或喷洒系统的形式，单独适用筛分辅助设备。

该坚固结构与标准部件组合应用，一方面确保了高度的灵活性和以客户为中心的解决方案，另一方面也使得所制造的机器具备低维护运行时间和长使用寿命的特点。

Low-pressure dewatering screening machine

To meet a strong demand for low residual moisture

To meet especial demand for low residual moisture in e.g. sand, our low-pressure dewatering screening machine is an interesting alternative. It delivers lower residual moisture levels than linear-motion screening machines that are usually used for dewatering. This machine is based on the “dual-shaft screening machine” drive concept, because with this kind of vibration generation higher speeds can be reached. Higher speeds combined with a pneumatic low-pressure system have a marked lowering effect on residual moisture levels.

Advantages of our low-pressure dewatering screening machine:

• Customer-specific concept
• High dewatering performance
• Screen cloth to suit the screened material
• Low-clog dewatering
• Excellent vibration insulation
• Robust design
• Long-life time-tested components
• Optimally adapted drive concept
• Low-maintenance and repair-friendly

Hot standard screening machine

Hot-asphalt screening machine by SIEBTECHNIK TEMA with improved dust guard

For the manufacture of standard asphalt-bound base and surface layers stationary, semi-mobile or mobile asphalt mixing systems are employed. These consist essentially of a dry drum, bucket conveyor, screening machine, aggregate silos, weighing and mixing equipment and a shipment loading system.

The aggregates, which make up about 80 to 90 per cent by weight of the asphalt formulation, are heated to the required temperatures in the burner-heated dry drum. The quality of the asphalt layer depends on, amongst other things, the quality of the binding materials and the correct grain composition of the largest component by volume, the grainy aggregates. For this reason the screening machine is of especial importance

The SIEBTECHNIK TEMA type HN screening machine has the advantage that the drive mounting is positioned outside the fixed dust guard enclosure and so outside the heating zone. Hot chippings at temperatures of up to 450 °C have been reliably screened with this system in numerous applications.

Here the right choice of screen cloth and the kind of screen cloth tensioning is also important.

The excellent accessibility of the machines in combination with dust guard covers that enable temperatures to be rapidly lowered are an important requirement for short down-times in cases of maintenance or repair. The dust guard available since 2001 in the new, split version with fully extendable chute carrier brings a further improvement on earlier systems here.

Advantages of our hot standard screening machine:

• Customer-specific concept
• Temperature resistance of the components
• Drive system, screen box and screen cloth to suit the screened material
• Compact design
• Low-clog classification
• Excellent vibration insulation
• Robust design
• Long-life time-tested components
• Optimally adapted drive concept
• Low-maintenance and repair-friendly
