PSJ-20/320T

DINOSAW stone cropper combines hydraulic precision with industrial durability for efficient stone splitting. Hightonnage splitting force (20-350 tons) ensures clean breaks across granite, marble, and concrete with customizable blade systems and automated conveyor integration. Perfect for producing curb stones, wall claddings, paving slabs, and architectural elements. Our machines boost production efficiency 3X faster than traditional methods while maintaining natural textures.

Hydraulic Stone Splitting Applications

Hydraulic splitting of natural split-face products: veneer, wall stone, pavers, curbstones and retaining wall blocks.

The PSJ hydraulic stone cropper converts stone blocks and slabs into natural split-face products with five force classes from 20 to 320 tons — clean fractures, no saw kerf, and a quick-change blade system that returns to production in minutes.

Real Splitting Performance & Key Metrics

Five Force Classes

PSJ-20T to PSJ-320T covers splitting widths from 160 mm to 1200 mm and heights from 180 mm to 800 mm — one platform, five production scales.

Kerf-Free Splitting

Stone fractures along its grain instead of being sawn, so material is not lost as blade kerf.

Energy-Efficient Hydraulics

Variable-speed pumps and pressure optimization cut power consumption by about 25% against constant-pressure hydraulic designs.

Natural Fracture Mechanism

A hardened splitting blade concentrates hydraulic force into the stone until it separates along its natural grain — the result is a genuine split-face texture with no saw kerf and no need to artificially texture a sawn surface afterward.

Five Force Classes

The 20, 40, 70, 160 and 320-ton classes match product cross-section and stone hardness instead of oversizing the hydraulic system for every job — thin veneer runs on the PSJ-20T, full-size blocks on the PSJ-320T.

Quick-Change Blade System

The quick-change system replaces splitting blades tool-free in about five minutes, minimizing downtime between product sizes — no wrenches or fixtures required.
