Look! This 75kw Diamond Wire Saw machine is performing stone capping removal. Here, we're going to create a marble quarrying surface. You might wonder, isn't stone capping removal the job of excavators? When did wire saw machines start to be used for this? In this video, let's explore the "first step" of marble quarrying - stone capping removal - and uncover how wire saw machines shine in this crucial stage! Whether you're a quarry enterprise manager or an industry professional, mastering this knowledge can boost efficiency and cut costs!

[Part 1: What is stone capping removal?]

Hello, I'm Oliver Mo, engaged in the production and sales of wire saws. When it comes to stone capping removal, as the name suggests, it means removing the "cover" on the marble ore body. These "covers" include soft topsoil, weathered rock layers, and hard overlying rock layers, with thicknesses ranging from a few meters to dozens of meters. To quarry qualified marble blocks, these overburden layers must be cleared before quarrying.

[Part 2: How to scientifically conduct stone capping removal?]

stone capping removal isn't just brute - force excavation; it's a meticulous three - step process:

Layered stripping: First, strip the topsoil and store it separately for future mine reclamation.

Slope reinforcement: Through stepped excavation (with a slope of 45 - 65°) combined with bolt support, ensure the stability of the stone. This prevents landslides during subsequent quarrying. This step is extremely important. Some small and medium - sized quarries don't pay enough attention to slope reinforcement to save costs. Here, I'd like to emphasize that everyone should value it because safety in production is of utmost importance.

Wire saw cutting: After the excavator has cleared the surface vegetation, soil, and weathered rock layers, the exposed stones are uneven. This is when our wire saw machine comes into play. Drill holes, thread the wire, and cut to create a flat quarrying step, forming a display surface to show the quality of our stone to block purchasers. The wire saw machine deserves all the credit for this.

[Part 4: How to choose a wire saw machine for stone capping removal?]

When performing stone capping removal cutting, the cutting area is usually large, and due to the uneven surface, there are many angles where the wire can get stuck. So, when choosing a wire saw machine for stone capping removal, it's recommended to use the 75KW Power save master (PSM) wire saw machine. The advantages are as follows:

I) High torque with a constant value. Even at the start, it can pull the wire for cutting on its own, without the need for manual assistance to start the saw, which is safer. Once manual intervention is required, there will be safety risks!

II) Strong power. The 75KW permanent magnet synchronous motor can handle a wire length of up to 150 meters, with a wide cutting range and low power consumption, saving a lot of electricity.

III) Intelligent control. It has an automatic cutting and fault feedback system. The machine cuts independently, automatically judging the tension. If the wire is loose, the machine automatically speeds up the backward movement; if the wire is tight, it automatically slows down. When the machine detects a fault, the console display shows the fault code. The manufacturer's technicians can quickly find the cause of the fault through the code and resolve it via remote video assistance!

The slogan of the Power save master (PSM) wire saw machine is "Cut fast, with great power, and huge energy savings".
