馈线有几种类型. Choosing the right one for your application should be based on the characteristics of the material to be handled and the required capacity.
Selecting a Feeder for a particular situation is not always simple, 然而, especially if more than one satisfactory solution appears possible.
Some of the criteria for choosing the proper Feeder includes:
1. 级配和块状尺寸
First, consider the gradation of the material the Feeder will handle. Be sure to include the largest lump size (even if it is less than 1% of the total gradation) as well as the smallest particle size in this analysis.
2. 进给速率
下一个, 确定给料器的容量, 考虑设计最大值, 正常和最低容量. Determine if the feed rate is going to be fixed or variable.
3. 材料类型及其特性
考虑给料器将要处理的材料. When sizing a Feeder, it is important to know the following information about the material:
- 硬度
- 密度
- 磨损性
- 形状
- 休止角
You'll also want to consider if the material is free-flowing, sticky, wet or dry.
4. 温度
Consider the material temperature and the ambient temperature range at the operation site.
5. 是否需要剥头皮??
如果物料是由加料器剥离的, consider the desired size of the material and what percent is to pass the opening. Determine if there is one scalping size or multiple sizes.
6. 操作职责类型
Consider how many hours and days per week the Feeder will be operating.
7. 便携式或固定式
Determine if the Feeder is going to be installed on a portable or stationary plant, and know if weight and size of the Feeder will be a factor.
8. 可用空间和场地设施
Consider the space that is available for the Feeder. 如果这是地下矿井, know if there is a limit to the size and weight that can be transported in the mine shaft or tunnel. Also consider how much space is available for maintenance.
Site amentities are another important aspect to consider when sizing a Feeder. Be sure to consider the type of power available at the site (line or generator), 如果你喜欢液压或电力驱动. Also take into account the elevation and climate of the site.
9. 装载类型
Consider how the Feeder will be loaded (haul truck, wheel loader, 输送机, 压碎机, etc.)，并知道这台设备的大小.
10. 下游设备类型和尺寸
Consider the type of equipment the Feeder is charging (truck, 火车, 输送机, 压碎机, 筛子或黄牛). Also consider the type and size of 压碎机 or downstream equipment the Feeder is planned to feed.
馈线类型
馈线的类型包括:
围裙喂食器
的 板式给矿机 is higher on capital investment and higher on investment returns. It is the most robust Feeder and is commonly used in the mining industry under 24/7 operation with years between maintenance periods.
胶圈给料机用于:
- 小容量和大容量
- 极端冲击载荷
- 均匀进料速率
- 多种材料, such as minerals, aggregates and recyclables
- 使用寿命长，维护费用低
- 定制的应用程序和安装
- 非常困难的, 磨料和韧性, and for lumps of larger dimensions and that which are beyond the scope of other Feeders
带食动物
带食动物 are generally used for fine material applications. 的se are flat belt 输送机s supported by closely spaced idlers and driven at the head pulley.
带式给料机用于:
- 较小尺寸的材料
- 小漏斗
- 二级或三级应用
往复/板喂
的se Feeders are a reciprocating tray-type feeder. 的 reciprocating motion is produced mechanically by a crank or eccentric and connecting rod, or hydraulically operated by a hydraulic cylinder. 的 Feeder discharge occurs during the back stroke of the plate — no material is discharged in the forward stroke.
Plate Feeders are generally installed under a bin and are used for:
- 小容量和大容量
- 循环进料速率
- 使用寿命长，维护费用低
- 定制的安装应用程序
振动灰熊喂食器
振动灰熊喂食器 are smaller in size than 围裙喂食器 and are used 在破碎机之前需要预先分选的地方. 物料沿着管道输送 pan of the Feeder as a result of the vibrating motion imparted to the particles. This vibration pre-sorts the material, passing the fines to the bottom. 的 fines can then be pre-screened before a 压碎机, thus reducing the required capacity and wear.
振动给料机用于:
- 中小型容量
- 接近均匀进料速率
- 多种材料
- some 定制的安装应用程序
的se Feeders are lower on capital investment and lower on investment returns.
梅花头喂
物料沿着管道输送 梅花头式给料机 as a result of the rotating motion of the elliptical bars. This motion scrubs and pre-sorts the material, passing the fines to the bottom. 的 fines can then be pre-screened before a 压碎机, thus reducing the required capacity and wear. 的 梅花头式给料机 is high on capital investment and medium on investment returns.
摆动给料器用于:
- 中小型容量
- 在破碎机之前需要预先分选的地方
- 均匀进料速率 (dependent of homogenous feed gradation)
- generally used for sticky types of materials to scrub the fines off
梅花头喂 are not used for any round or slick material such as gravel or coal.
了解选择喂食器的标准, 以及喂料器类型的差异, can help you determine the right one for your application. If you need further assistance choosing a Feeder, 菠菜网最稳定正规平台_最全菠菜网大全 今天!
