Feeder-Breakers vs. 喂料机和浆料机 in raw coal processing applications
喂食器, which include Vibrating Plate, 围裙, 往复式板, 拖链和皮带, are used universally in ROM raw coal processing operations to;
- Accept high volumes of bulk ore
- Allow surge capacity between bulk ore deliveries
- Deliver the ore in a controlled manner to the primary sizing equipment.
Most ROM coal circuits include a type of Feeder and Sizer. The type of Feeder chosen for the application is dependent upon the type of feed, the type of primary crusher and the method of delivery to the hopper. Factors effecting the feed include material top size, 体积密度, percentage and type of fines, 粘土和水分.
A 菠菜网最稳定正规平台_最全菠菜网大全 Feeder-Breaker is a Feeder and Crusher in one compact, 低调的, 水平的单位, and therefore will take up less vertical and horizontal footprint than a Feeder and Sizer.
Feeder-Breaker Benefits
- Typically, a Feeder-Breaker will require less power to operate than a Feeder and Sizer combination.
- Oversize rocks in a Feeder-Breaker can be reversed through the rear door but can often get stuck in the Feeder’s head chute, making it very costly to remove.
- Feeder-Breakers是, 在所有情况下, shorter and have a much smaller footprint for the same capacity than a Feeder and Sizer combination.
- Feeder-Breakers是 less expensive than a Chain Feeder and Sizer combination, both in equipment and infrastructure costs.
基础设施
The infrastructure requirements will differ depending on the type of Feeder and Sizer chosen. The Feeder-Breaker is often the most cost-effective option.
The retaining wall is a major capital cost consideration. As the retaining wall height increases it’s costs increase exponentially, along with the costs of the elevated ROM pad. With a Feeder and primary Crusher installation, generally the retaining wall height is significantly higher than for a Feeder-Breaker with an equivalent ROM hopper capacity.
To fit two machines in a ROM station, the Feeder is typically designed on an angle. This increases the length of the Feeder to obtain the necessary height to feed into the 主要的 Sizer chute. With this design the ROM hopper capacity is reduced, and the Feeder and the support structure costs are increased.
By using the same wall height as the above example, it is possible to create two stages of crushing by inserting a Feeder-Breaker as the primary crusher.
Dozer push type Feeder-Breakers also offer cost savings over Feeder and Sizer designs as they have a reduced height for the primary crushed product.
感知到的弱点
There is a perception that Feeder-Breakers have difficulty in gripping and processing large lumps. In the past other suppliers provided poorly designed machines with small diameter breaker heads or even breaker barrels which caused this issue. A 菠菜网最稳定正规平台_最全菠菜网大全 Feeder-Breaker has neither of these design flaws.
Another perception is that Feeder-Breakers allow slabby material to be passed to the secondary crusher. While it is possible for slabby material to pass if the breaker head is raised high enough, in practice a correctly designed breaker head produces the correct sized feed for the secondary crusher. On 菠菜网最稳定正规平台_最全菠菜网大全 Feeder-Breakers the risers on the flights interact with the breaker picks to ensure long slabby feed lumps are efficiently broken up.
Feeder-Breaker Features
A well-designed Feeder-Breaker includes;
- Tungsten carbide tipped picks. They are relatively inexpensive, easy to replace, and are low-wearing crushing components
- Automatic chain tensioning
- Hydraulically operated rear door for ease of access
- A correctly designed breaker head
- Side and top access doors
- Discharge access and hydraulically actuated laydown door
- Bolt-on chain hold downs, plug welded Q & T steel deck plates with Q & T bolted side and skirt plates.
These all add to the maintenance friendly and time-savings features of the 菠菜网最稳定正规平台_最全菠菜网大全 range of quality equipment.
