Automatic Four-Blade Cubic Stone Splitting Machine for Granite & Pavers

What Is a Cubic Stone Splitting Machine?

Product display and finished product display

A cubic stone splitting machine is hydraulic stone-processing equipment used to split prepared natural stone bars into smaller cubes, cobblestones, paving setts and other natural split products.

Unlike a diamond saw, the machine does not cut through the complete finished surface.

Hydraulic force is applied through splitting tools until the stone fractures naturally.

This allows the finished product to keep the rough texture and natural mineral appearance that many paving and landscape projects require.

Typical products include:

• Granite cubes
• Cobblestones
• Paving setts
• Landscape paving
• Courtyard paving
• Natural stone blocks
• Architectural paving stone
• Rustic landscape products

The Speedone KSL-24S is particularly suitable for repeated cube-stone production because it combines four-blade hydraulic splitting with a self-sliding feeding concept.

Speedone KSL-24S Four-Blade Cubic Stone Splitting Machine

The KSL-24S is designed around three important features:

• Four-blade splitting tooling
• Automatic working cycle
• Self-sliding stone feeding

A typical production concept is:

Prepared Stone Bar → Self-Sliding Feed → Position → Four-Blade Hydraulic Split → Cubic Stone → Continue Production

This configuration gives the KSL-24S a more specific production role than a general-purpose stone splitter.

Its main focus is repeated production of relatively small natural-stone cubes and paving products from prepared stone bars.

Why Use Four Blades for Cubic Stone Splitting?

Cubic stone production can require controlled fracture around more than one side of the workpiece.

The KSL-24S uses a four-blade arrangement designed to apply splitting force from multiple directions around the working position.

This can be useful when producing:

• Natural stone cubes
• Granite paving cubes
• Cobblestones
• Small landscape blocks
• Rustic paving products

The tooling arrangement can influence:

• Where the fracture begins
• Finished cube geometry
• Edge condition
• Natural surface appearance
• Production repeatability

The exact tool movement and pressure sequence should follow the operating instructions for the specific Speedone configuration.

Main Structure of the Cubic Stone Splitting Machine

Rigid Vertical Main Frame

The KSL-24S uses a strong vertical frame around the active splitting area.

The frame supports the hydraulic working assembly and helps keep the tooling aligned during repeated production cycles.

Four-Blade Splitting Assembly

The central working section contains the four-blade tooling system.

The tools are arranged to concentrate hydraulic force around the stone working position rather than relying only on one upper blade.

Self-Sliding Feeding Structure

The front of the machine includes an angled roller-style feeding section.

This helps support prepared stone bars and allows the remaining material to move toward the next splitting position after a completed cycle.

Roller Stone Support

Multiple rollers support the incoming workpiece.

This can help with:

• Stone-bar movement
• Repeated feeding
• Workpiece positioning
• Reduced dragging resistance
• More organized material flow

Independent Hydraulic Power Unit

A separate hydraulic power unit supplies the pressure required for the splitting cycle.

Exact pump capacity, motor power, hydraulic pressure and oil specifications are model-dependent.

Electrical Control Cabinet

The machine also includes a separate electrical control cabinet.

This supports the approved automatic working sequence for the selected machine configuration.

How Does a Four-Blade Cubic Stone Splitting Machine Work?

A typical process is:

Prepare Stone Bar → Inspect → Load → Self-Sliding Feed → Position → Four-Blade Split → Release → Advance → Repeat

1. Prepare the Stone Bar

The raw stone is first cut into a suitable rectangular bar.

2. Inspect the Material

Check the stone for serious cracks, loose areas or unstable defects.

3. Load the Stone

Place the prepared bar on the approved feeding structure.

4. Feed the Stone Forward

The material moves toward the splitting position according to the configured working sequence.

5. Position the Workpiece

The required cubic-stone section is positioned inside the active splitting area.

6. Apply Four-Blade Hydraulic Force

The splitting tools apply concentrated hydraulic force around the intended fracture area.

7. Complete the Split

The stone fractures and the finished cube or paving piece can be removed.

8. Advance the Remaining Bar

The remaining stone moves forward for another production cycle.

This repeated workflow makes the machine particularly suitable for industrial cube-stone production.

Cubic Stone Splitting Machine for Granite

Granite is one of the most common materials used for natural cubic paving stone.

Typical applications include:

• Pedestrian streets
• Public plazas
• Courtyards
• Garden paths
• Landscape projects
• Driveways
• Historic-style paving

A typical production process is:

Granite Block → Saw-Cut Bar → Four-Blade Splitting → Granite Cubes → Sorting → Packing

Granite can vary according to grain size, mineral composition and quarry source.

The machine should therefore be matched to the actual stone being processed rather than selected only according to dimensions.

Cubic Stone Splitting Machine for Cobblestones

Cobblestone production normally requires repeated processing of prepared stone bars.

A self-sliding feeding system can be useful because the remaining material needs to advance after each completed split.

Possible finished products include:

• Granite cobblestones
• Natural paving setts
• Landscape cubes
• Rustic walkway stone
• Decorative road paving

Hydraulic splitting creates a more natural appearance than completely saw-cut paving products.

Cubic Stone Splitting Machine for Paving Stone

Cubic stone is widely used for paving because individual units can be installed in many different patterns while retaining a natural stone appearance.

Typical applications include:

• City paving
• Landscape paving
• Courtyard paving
• Garden paths
• Commercial plazas
• Architectural outdoor areas

When the finished product needs natural fractured surfaces, hydraulic splitting is the more suitable processing method.

If the required paving product instead needs a mould-defined pattern or decorative profile, Speedone’s paving stone stamping machine uses a different production process.

Cubic Stone Splitting Machine for Marble

Suitable marble can also be processed with hydraulic splitting equipment.

However, marble often contains veins that can influence the fracture direction.

Important factors include:

• Marble variety
• Vein direction
• Stone-bar dimensions
• Stone thickness
• Required cube size
• Stone orientation

Representative material testing can be useful before starting volume production with a new marble type.

Why Stone Bar Preparation Matters

Automatic cubic-stone production works best when the incoming stone is already prepared into suitable rectangular bars.

A typical upstream process is:

Raw Block → Primary Sawing → Secondary Cutting → Rectangular Stone Bar → Cubic Stone Splitting

Consistent stone bars can improve:

• Feeding stability
• Tool positioning
• Finished dimensions
• Production rhythm
• Product repeatability

If incoming bars vary too much in width, height or straightness, the operator may need more adjustment during production.

Four-Blade vs. Two-Blade Stone Splitting

Both four-blade and two-blade machines can be used in cube and paving production, but their tooling concepts are different.

Blade count alone should not determine the purchasing decision.

The correct configuration should match the stone, incoming bar dimensions and required finished cube.

Cubic Stone Splitting Machine vs. Automatic Stone Splitter

An automatic stone splitter is a broad equipment category covering many different stone sizes and products.

A cubic stone splitting machine has a more specific production focus:

• Prepared stone bars
• Repeated cube production
• Natural paving setts
• Cobblestones
• Automatic or self-sliding feeding

For buyers comparing the wider automatic splitting category, Speedone’s automatic stone splitter for granite and marble provides a broader overview.

Cubic Stone Splitting Machine vs. Mushroom Face Splitter

The two machines use hydraulic fracture for different finished products.

A cubic stone splitting machine is mainly used to divide prepared bars into cubes or blocks.

A mushroom-face machine focuses on trimming selected stone edges while keeping a raised natural central face.

For wall stone and mushroom-face processing, Speedone’s natural stone splitter and mushroom-face trimming alternative covers that specialized application.

Cubic Stone Splitting Machine vs. Granite Stamping Machine

A natural granite cube and a stamped granite paver have different appearances.

Splitting creates a natural fracture.

Stamping uses a mould or defined tooling to create a controlled shape or decorative pattern.

Factories producing patterned granite paving can review Speedone’s granite stamping machine for pavers.

Cubic Stone Splitting Machine vs. Stone Pressing Machine

For mould-based stone processing, see Speedone’s stone pressing machine for granite and marble.

Cubic Stone Splitting vs. Hydraulic Stone Stamping

Hydraulic stone stamping uses approved moulds to produce decorative stone products.

Cubic stone splitting uses concentrated force to create natural fractures.

Splitting is more suitable for:

• Natural stone cubes
• Cobblestones
• Paving setts
• Rustic blocks

For mould-defined decorative products, buyers can compare Speedone’s hydraulic stone stamping machine.

Cubic Stone Splitting Machine vs. Diamond Saw

The two machines normally work at different stages of production.

The saw prepares the stone bar.

The splitter creates the final natural fractured surface.

A practical production concept is:

Diamond Saw for Stone Bars → Four-Blade Cubic Stone Splitting Machine for Finished Natural Cubes

Why Self-Sliding Feed Matters

After one cube is split, the remaining stone bar needs to move into position for the next cycle.

Repeated manual movement can take a significant part of total production time.

A self-sliding feeding structure can help organize:

• Material movement
• Repeated positioning
• Stone support
• Production rhythm
• Operator workflow

The exact feeding sequence remains model-dependent and should follow the approved operating procedure.

How Much Hydraulic Force Is Required?

There is no single hydraulic-force value suitable for every cubic-stone application.

The required force depends on:

• Stone type
• Material strength
• Stone-bar width
• Stone-bar height
• Natural grain
• Tool geometry
• Finished cube dimensions

A practical selection process is:

Stone Material → Stone Bar Dimensions → Finished Cube Size → Four-Blade Tooling → Hydraulic Requirement → Machine

Higher hydraulic force does not automatically mean a better finished product.

Planning a Cubic Stone Production Line

A complete production workflow may include:

Raw Stone Storage → Primary Sawing → Stone Bar Preparation → Staging → Self-Sliding Feed → Four-Blade Splitting → Cube Collection → Sorting → Packing

The splitting machine is only one part of the production line.

Actual output may also be limited by:

• Slow stone-bar preparation
• Inconsistent bar dimensions
• Material loading
• Finished-cube removal
• Sorting
• Packing

The complete workflow should therefore be considered when evaluating production capacity.

How to Choose the Right Cubic Stone Splitting Machine

1. Define the Stone Material

Specify granite, marble, limestone, sandstone, basalt or another compatible natural stone.

2. Define Stone Bar Dimensions

Provide normal length, width and height.

3. Define Maximum Workpiece Size

The feeding structure and working opening must accommodate routine maximum pieces.

4. Define the Finished Cube Size

Provide the required length, width and height.

5. Define the Finished Surface

Provide photographs showing the desired natural fractured appearance.

6. Evaluate the Four-Blade Configuration

Confirm that the tooling arrangement suits the stone and finished product.

7. Evaluate the Feeding System

Determine whether the self-sliding configuration matches the planned production workflow.

8. Evaluate Hydraulic Capacity

Required force should be matched to the actual material and workpiece dimensions.

9. Consider Stone Support

Long or heavy stone bars need stable support throughout feeding.

10. Define Production Target

Estimate realistic output per shift rather than considering only hydraulic cycle time.

11. Consider Wear Parts

Discuss splitting tools, rollers and hydraulic wear components before purchasing.

12. Evaluate Supplier Support

Technical documentation, spare-parts availability and application support are important for professional stone machinery.

Raw-material and finished-product photos are especially useful because they help define the real stone, dimensions and required natural split appearance.

Common Cubic Stone Splitting Problems

Stone Fractures Away from the Intended Position

Natural grain, veins, bedding or internal cracks may influence the fracture path.

Cubic Stone Dimensions Vary Too Much

Check incoming stone-bar dimensions, feeding position and tooling alignment.

One Side Breaks More Than the Others

Inspect stone geometry, workpiece support and four-blade contact.

The Stone Does Not Move Smoothly

Inspect the feeding path, roller condition, workpiece size and stone support.

Tool Contact Is Uneven

Check tooling alignment and stone positioning before continuing production.

Production Is Lower Than Expected

Measure stone preparation, feeding, splitting, finished-product removal, sorting and packing separately to identify the actual bottleneck.

Cubic Stone Splitting Machine Maintenance

Routine inspection should include:

• Hydraulic oil
• Hydraulic cylinder
• Hydraulic pump
• Electric motor
• Hydraulic hoses
• Fittings
• Pressure controls
• Four-blade splitting tools
• Tool guides
