Feeding a crusher correctly is as important as the crusher itself.If misused,you lose production and increase wear costs.The article helps you find the ideal setup for feeding your small rock crusher.
Small Rock Crusher Feeder Types
Typically,mobile rock crushers feature 3 types of feeders-a belt feeder,an pan feeder,or a virbrating hopper.A belt feeder is commonly used on mini crushersfor light.A pan feeder with a static hopper walls is typically being used with a wide range of mobile and portable rock crushing plants.
Belt Feeder
A belt feeder features static hopper walls and a conveyor belt that conveys the material into the crusher.This type feeder is ideal for light-duty applications such as sand&grave,asphalt,bricks,and fairly clean concrete.Sharp shot rock or heavy rebar could puncture or damage the conveyor belt.The beauty of the belt feeder is that you can easily reverese the direction in case of a blockage at the crusher inlet.
Small rock crushers with a belt fedder can be easily fed with a skid-steer or mini excavator because of the low feed height of this feeder.
Belt feeders are usually used by mini jaw crushers,most mobile cone crushers,the RM 60 compact crusher,and the RM V550GO!mobile impact crusher.
Single-Piece Vibrating Hopper with Integrated Pre-Screen
This is a common setup for a small rock crusher.The hopper ,fedder floor,and pre-screen shake as one compact unit.The benefit of this type feeder is that fines can bypass the crusher and merge with crushed material on the bottom of the crusher.
The single piece vibrating hopper is suitable for a wide variety of applications.You will face challanges with dirty material as it can build up in the rear or clog the pre-screen grizzly rendering it useless.This type feeder is best fed with an excavataor or small wheel loader.Wide loader buckets could be a problem because you would dump material onto the screening area reducing the pre-screen effectiveness and increasing the risk of a material blockage.
It is commonly used on compact rock crushers.
Vibrating Pan Feeder with Integrated or Independent Active Pre-Screen
This feeder setup is common in mobile rock crushing plants and has static side-walls with a vibrating floor that conveys the material forward.Also common,are optional hopper capacity and facilitate feeding the rock crushing plant from the distance.Larger rock crushing plants feature the option of either a vibrating grizzly or a fully independent active pre-screen to improve the scalping action before crusher inlet.
Larger rock crushing plants are best fed with an excavator or a wheel loader.
