LBJ-3200 / LBJ-4500 / LBJ-5600

The DINOSAW LBJ series is a quarry chain saw machine for mechanized dry cutting of marble, sandstone and other soft to medium-hard stratified stone. A diamond chain cuts straight, deep faces in both horizontal and vertical directions without process water, with three depth classes at 3,200, 4,500 and 5,600 mm. PLC control manages the cutting cycle, while the hydraulic system automatically adjusts cutting parameters with stone hardness. An IoT remote data collection module and a wireless remote control are available as factory options for quarries running multiple machines or high benches. The LBJ fits quarries where diamond wire sawing is uneconomical on soft stone, and it works alongside the KSSJ wire saw rather than replacing it: in the high-bench extraction method, the chain saw separates one connecting face while the wire saw cuts the other two.

Quarry Chain Saw Applications in Marble & Sandstone Quarries

The LBJ series serves dimension-stone quarries dominated by long straight faces in soft to medium-hard stratified stone, where dry mechanized cutting avoids water logistics and makes wire sawing uneconomical.

The LBJ series is a quarry chain saw machine for mechanized dry cutting of soft to medium-hard stratified stone such as marble and sandstone. It opens straight, deep vertical and horizontal faces where diamond wire saws cut too slowly to be economical, and it separates one connecting face in the high-bench method while a wire saw finishes the block.

Real Cutting Performance & Key Metrics

Maximum Cut Depth Classes

Three depth classes let the quarry size the machine to the tallest regular bench face instead of buying depth it never uses or running a shallow machine at its limit.

Catalog Cutting Efficiency

The quoted 3–7 m²/h range covers the soft-to-medium-hard stone band; actual output depends on stone hardness, chain condition and depth per pass, and is confirmed against the quarry's stone.

Total Installed Power

The LBJ-3200 runs on 53 kW for lower benches, while the LBJ-4500 and LBJ-5600 use 65 kW to hold chain speed through deeper, harder cuts.

Dual-Direction Dry Cutting Chain System

The diamond chain cuts straight faces in both horizontal and vertical directions without process water. Dry cutting removes water logistics and slurry handling from the bench, which is decisive in arid quarries or sites without settling ponds.

PLC-Controlled Cutting Cycle

The PLC manages the cutting sequence, travel and positioning parameters, replacing manual judgment on repetitive long cuts. Operators run consistent cycles shift after shift, and parameter recall speeds up repositioning between faces.

Hydraulic Hardness-Adaptive System

The hydraulic system automatically adjusts cutting parameters as stone hardness changes along the face. A chain cutting from soft into harder bands keeps stable load instead of stalling or over-feeding, protecting both chain and drive components.
