Relation amplitute,vibration number with feeding velocity

根据移送物的比重, 水分, 粒度, 特性等在其理论移送速度和实际移送速度上也可存在差异, 但一般情况下根据以下公式预测移送速度参考值.


▶ TROUGH水平时的移送速度
移送速度V[M/min] = 3.81NS (N: [vpm], S: 振幅 [M])

计算实例)
振幅为1010mm, 振荡数为600vpm的传输带的理论移送速度为V=3.81×600×0.01=22.86M/min.
但是上述理论推断速度以具备适当的振荡角度和移送所需的垂直角度做为前提. 一般情况下, 在设计中只反应上述理论推断值70~80%左右后进行工序设计.

How to calculate for feeding capacity of materials

振动传输器的移送量根据处理物的特性(粒度, 水份含有量, 粘贴性等)和凹槽的角度, 振动角度等方面的问题会有些差异, 但是为工程设计的理论推算数据用下方的计算法可以推算, 更正确的理论保证由贵公司的技术部确认.

Q = 60 (ρ · B · H · V)
Q : 传送量 [TON/HR]
ρ : 外观比重 [TON/M3]
B : 凹槽的宽度 [M]
V : 传送速度 [M/min]

Feeding Capacity

条件

Bulk density:1.2 ton/M3
Trough width:0.6 M
Material depth of flow:0.05M
Feeding speed:16 M/min

根据以上的条件来计算传送量,

Q=60(0.8×0.6×0.05×16) =23.04 TON/HR

但上述堆积高度(H)是假设数据, 取决于产品的粒度或特性的限制数据, 非无限定可以假设的数据. 一般振动传输器的设计为300mm以下, 装有SKIPT的振动式给料器以900mm以下的标准来设计.
