Quarrying stone block cutting machine

Types of quarrying stone block cutting machines

A quarrying stone block cutting machine is used in stone quarries to cut large blocks of stone from the quarry into smaller, more manageable blocks or slabs for further processing. Different types of machines perform this function, including diamond wire saws, gang saws, block cutters, wall saws, and jet stream cutters.

• Diamond wire saw machine:

The most commonly used device for cutting stone blocks is the diamond wire saw. It is a machine that uses a wire with diamond segments to cut through various materials, including granite, marble, and other hard stones. Because it can make precise cuts at high speeds, this kind of saw is perfect for quarrying stone blocks.

The cutting wire's flexibility makes it possible to make intricate cuts, which reduces material waste. In comparison to traditional cutting methods, diamond wire saws are known for their smooth-cut surfaces and low noise and vibration levels. They can be used for both vertical and horizontal cutting and are available in a range of sizes and specifications to meet different needs.

• Gang saw machine:

A power tool known as a gang saw is used to cut through stone blocks in a quarry. A gang saw is made up of several saw blades spaced apart on a single frame. These blades are then set into motion by a motor to cut through a variety of materials, including stone, metal, and concrete.

Despite being versatile tools for cutting through a variety of materials, gang saws are especially well-liked for their ability to cut stone blocks with precision. The gang saw is able to saw multiple stone blocks at once with high efficiency and accuracy thanks to its multiple blades. The productivity of a quarry may increase as a result, as may the cost-cutting opportunities.

• Block cutter machine:

In stone quarries, block cutter machines are utilized extensively. The primary purpose of these machines is to cut large stone blocks into smaller blocks or slabs. Electric or hydraulic power sources are commonly used to operate block cutters, which are made to handle various types of stones like granite, marble, and limestone.

Block cutters generally operate by using either a fixed blade or a movable stone to make cuts. The process can be automated or manual, depending on the machine model and specifications. While some block cutters may only be able to handle particular stone types and sizes, others are adaptable to many situations. Overall, block cutter machines are essential tools in the stone quarrying industry, making them an indispensable part of the stone processing workflow.

• Wall saws:

Sawing walls is precisely what wall saws are meant for; they are great for cutting through thick and heavy materials like concrete, stone, and bricks. In a stone quarry, wall saws are utilized to cut stone walls or sections precisely and quickly. Usually, an electric motor or a petrol engine is used to power them, and they have a rigid frame with a rectangular or circular blade mounted on it.

Wall saws offer several advantages. For example, they have the capacity to perform deep cuts, precision cutting and allow for diverse cutting patterns and angles. They can also be used for both horizontal and vertical cuts. As a result, walls saws have become standard equipment for cutting stone in quarries because of their versatility and precision.

• Jet stream cutter machines:

The term "jet stream cutter machine" refers to a mechanical device that uses high-pressure water jets to cut different materials, such as stone, metal, and ceramic. These cutters utilize a method of cutting that is efficient and effective, employing the power of high-pressure water streams. In addition to being precise, controlled, and having a minimal environmental impact, jet stream cutters are capable of producing complex shapes and high-quality cuts.

Machines that cut jet streams are quite flexible, making them appropriate for a variety of applications across sectors. Stone, metal, and ceramic cutting is just one of many uses for them; they are also used in the automotive, aerospace, and manufacturing industries, among others. A water treatment facility or water recycling system is required for jet stream cutters to function appropriately, as they consume a lot of water.

Specification & Maintenance

• Stone Block Size: The machine can work with block sizes of up to 3500mm(L) x 1200mm(W) x 1200mm(H).
• Cutting Thickness: The machine's cutting thickness or width is 5mm. It may be possible to achieve thicker cuts with other models or blades, but this is a standard thickness for precision cutting.
• Cutting Accuracy:The cutting accuracy of a quarry block cutting machine usually refers to its original cutting size and the final block size after cutting. The standard accuracy is usually ±1mm.
• Motor Power: It usually ranges from 22kw to 37kw. A 22kw motor may be sufficient for handling softer stones like sandstone or limestone. However, a more powerful 37kw motor may be preferable for harder, more robust, and larger capacity machines to ensure efficient cutting.
• Control System: These machines are controlled using microcomputer control, PLC systems, or other control systems with preset programs and touch-screen interfaces.
• Water Consumption: The machine may use approximately 20 liters of water per minute for cooling purposes during cutting. This can vary from 10 L/min to 30 L/min depending on the type of stone, cutting speed, and specific machine settings.

The maintenance requirements for a stone quarry cutting machine are as follows:

• Daily Inspection: It is essential to inspect the machine to see if there are any loose parts, cracks, or signs of damage. Look at the saw blade's edges and teeth to check for any wear and tear or damage, and see if it is properly aligned and tensioned. Check the hydraulic system for any visible leaks or damaged hoses. Check the belts and chains in the machine for any signs of wear and properly adjust them if necessary. A visual inspection of the cooling system should also include looking at the water pipes and reservoir for any leaks or clogs.
• Regular Lubrication: Lubricate the moving parts, chains, and bearings to reduce friction. Lubricate the machine's sliding rails using wax or any water-soluble lubricant to provide adequate support and a smooth cutting process. Clean the cutting table and rails to remove any debris or stone residues that may affect the cutting accuracy. Apply a thin layer of wax to the table and rails to help lubricate and protect them from corrosion or rust.
• Tool Maintenance: The saw blades are critical tools in the cutting process, affecting precision and efficiency. Regularly check their status to see if they are worn or damaged. Replace them promptly if there is any problem. Sharpen worn saw blades to maintain cutting efficiency and precision, which will also extend the blade's life span. Use appropriate sharpening equipment and follow the manufacturer's guidelines.
• Hydraulic System Maintenance: The hydraulic system is responsible for propelling the hydraulic saw, affecting its cutting performance and precision. Check the hydraulic oil level regularly to ensure it is within the required range. Change the oil filter and monitor its status to prevent contamination. Inspect hydraulic hoses and connections for any damage or leaks. Ensure that the hydraulic cylinders are lubricated and operate smoothly.
