Cone Liner Selection. There are a few key points that you need to consider when selecting the correct crushing chamber: Feed Size: Each chamber configuration has a maximum feed size that it can accept. Feed Grading: The maximum feed size is important; if there are a lot of fines in the feed or a lot of single size in the feed, it can cause issues with wear and output.
