Primary Stone Remving Double Roller Crusher

GSG8060‑1000 double‑speed double‑roller crusher is purpose‑built for raw‑material pretreatment in fired‑brick factories. It adopts a differential‑speed design between the high‑speed roller and low‑speed roller. The speed difference generates strong shear and extrusion force to separate hard stones from wet clay and dry‑clay effectively.

Most brick‑making equipment is vulnerable to damage by hard gravel contained in raw materials. This primary stone‑removal machine solves this problem fundamentally. It screens and crushes stones within feeding size ≤150 mm in advance, protecting subsequent extruders and brick‑forming machines.

Technical Parameters

Advantage

•  1. Differential‑speed crushing principle: 10:1 rotating‑speed difference delivers powerful crushing performance against hard rocks.
•  2. Heavy‑duty alloy racks: The replaceable tooth‑rack parts are made from wear‑resistant alloy, greatly lowering later‑period maintenance frequency.
•  3. Flexible gap adjustment: The roll gap from 20‑35mm is adjustable to match different raw‑material conditions and production output targets.
•  4. Reliable driving assembly: Matched with RS97‑18.5‑KW heavy‑load reducer, the whole‑unit operation is stable with low noise and fewer breakdowns.
•  5. Strong compatibility: Works well with clay, coal gangue, shale whether moist or dry, fit for worldwide brick‑plant projects.
