RSZL Series Four-Wheel Gear Direct-Drive Double Blade Quarry Saw

Low-Consumable Mining Equipment Tailored For Hard Granite Quarry Operators

Many granite mine owners face chronic operational troubles with conventional belt-driven mining machines: belts slip under heavy rock cutting load, frequent belt swaps waste production hours, and two-wheel drive easily drifts on rugged mountain rails, producing irregular waste rock. This four-wheel gear direct-drive double-blade quarry machine abandons the vulnerable belt transmission scheme entirely, adopting rigid hard-tooth gear transmission and balanced four-wheel travel system. Five complete size options cover small-scale family quarries up to large export-oriented mining bases, and all core cutting dimensions can be tailor-adjusted to match local mountain rock layer thickness and block specification demands.

Full Model Parameter Matching & Mine Positioning

Tiered Model Market Positioning

• Light-Duty Small Sizes RSZL3600 / RSZL3800

Carries medium-diameter cutting discs and dual low-power drive motors, with lighter overall weight to ease load pressure on simple temporary mine tracks. Ideal for newly launched small family quarries mining soft marble and low-density granite. The moderate total power draw keeps daily electricity operating costs under control, perfect for mine investors with constrained upfront procurement budgets.

• Universal Mid-Range Sizes RSZL4200 / RSZL4800

Equipped with mainstream 4200/4800mm saw blades paired with dual 65kW high-torque motors, capable of deep cutting up to 2150mm. The rigid gear transmission delivers steady cutting force to tackle most common hard granite types, becoming the mainstream pick for medium-sized commercial quarries supplying local stone slab processing factories.

• Super Large Heavy-Duty RSZL5200

Flagship model fitted with 5200mm ultra-large saw discs and twin 75kW heavy-duty motors, supporting ultra-wide cutting span of 3100mm and maximum cutting depth of 2350mm. Its 13-ton heavy body and four-point balanced drive system prevent sliding on uneven rough mountain tracks, specially developed for large-scale mining bases that supply oversized premium raw blocks for overseas engineering stone export orders.

Core Exclusive Advantages Of Gear Direct Drive & Four-Wheel Drive Design

1. Gear hard-tooth direct drive eliminates belt slipping and power loss

Different from traditional belt-driven mining machines, this unit uses integrated hard tooth surface gearbox for power transmission. No elastic belt stretching or slipping under heavy cutting load, 100% of motor torque is transmitted to saw blades. Even when cutting dense hard granite, the blades maintain constant rotation speed without stalling, reducing uneven kerfs and diamond segment abrasion. Gear components have ultra-long service life, erasing frequent belt replacement downtime and recurring spare part costs.

2. Four-wheel synchronous balanced walking adapts rough mine track terrain

Four driving wheels bear machine weight evenly, unlike two-wheel drive equipment that easily tilts and slips on bumpy, unpolished mountain rails. During deep cutting with heavy load, the machine travels in a straight stable path, guaranteeing parallel neat cutting seams between two blades. Less rock waste is generated, raising raw block yield rate and mine comprehensive resource utilization.

3. Built-in integrated jib crane simplifies on-site saw blade replacement

An independent lifting hoist is pre-installed on the machine body. Mine staff can independently complete disassembly, lifting and installation of tons of large saw blades without renting additional mobile cranes. It saves auxiliary equipment rental fees and shortens blade replacement time from half a day to within one hour, maximizing effective mining working hours every day.

4. Graded circulating water cooling system extends saw disc service life

Models are equipped with matched water flow according to cutting load. Small-spec machines adopt low-flow 5m³/h cooling, while the super-large 5200 version upgrades to 10m³/h high-flow water circulation. Continuous water flushing instantly carries away cutting heat and rock powder, avoiding high-temperature burning damage to diamond segments and lowering long-term saw blade procurement expenditure for mine owners.

5. Heavy integral anti-vibration frame stabilizes long-term mining precision

Thick steel plate full welding frame with total weight from 8.5 tons to 13 tons counteracts high-frequency vibration generated by double-blade synchronous cutting. Long-term uninterrupted mining will not cause frame deformation or walking deviation, ensuring consistent raw block dimensions every day and reducing post-processing trimming workload at slab factories.

Main Applicable Mining Scenarios

✅ Medium and large open-pit hard granite layered block mining operations

✅ Mines that prioritize low maintenance frequency and long continuous working hours

✅ Quarries producing oversized high-value raw blocks for engineering and export slab factories

✅ Mountain mine sites with uneven, rough track road conditions that cause two-wheel machine slipping

Long-Term Operational Value For Mine Investors

1. Cut recurring consumable cost: Gear drive removes regular belt replacement expense, stable torque slows saw blade wear.
2. Boost daily mining output: No power slipping or walking deviation, more effective cutting time per shift, larger daily raw block output.
3. Reduce auxiliary equipment investment: Built-in lifting crane eliminates mobile crane rental fees for blade replacement.
4. Adapt to diversified mining demands: Five gradient sizes plus customizable cutting width/depth fit small startup mines and large high-yield mining bases simultaneously.
