Hualong machinery multi blade stone block cutting machine
If you own a stone factory, how do you choose the most suitable machine?
First, you need to determine the type of stone your factory will be processing.
Marble: Soft stone, medium power, conventional saw blades, prioritize yield.
Granite: Hard stone, high power, high-rigidity structure, wear-resistant saw blades, prioritize stability.
Next, you need to determine the specifications of the raw blocks.
Core parameters: Maximum length × maximum width × maximum height of the raw block.
For blocks larger than 1500mm, multi-wire saws or multi-line saws are suitable.
For blocks smaller than 1000mm, a gantry saw is undoubtedly the best choice because of its low investment cost and high efficiency.
You also need to determine your factory's daily output requirements.
If you want high output, choose a high-spec 6-cylinder multi-blade saw. If your small factory doesn't have high output requirements, you can choose a standard model.
