When looking for a concrete crusher, there are several important features to consider. These include the type of crusher, the hopper size, and the horsepower. The type of crusher will determine what kind of material it can crush. There are jaw Crushers, impact Crushers, and rolling mills. Jaw Crushers are the most common and can crush most types of concrete. Impact Crushers use an energy beam to break the concrete into small pieces. Rolling mills use a series of rollers to crush the concrete into small pieces. The hopper size is important because it determines how much material the crusher can handle at once. The bigger the hopper, the more crushing power it has. A good rule of thumb is to get at least twice as much power as you need. That way, you won’t have to wait long for your project to start crushing materials. The horsepower is also important because it determines how quickly the crusher can move materials around. Higher horsepower models tend to be faster than lower horsepower models.
