Quick answer: A stone-industry filter press dewaters the fine slurry from granite, marble and quartz sawing and polishing into a dry, stackable cake of about 20–30% moisture and returns clear water to the saws. Chamber presses with large polypropylene plates, abrasion-resistant cloth and automatic plate shifting are the usual configuration; membrane plates are added when the cake must be drier for haulage or reuse.

Filter Presses for the Stone Industry | Sludge Dewatering Solutions for Granite and Marble Processing

Reliable Sludge and Wastewater Treatment Solutions for Granite, Marble, and Stone Processing Factories – Customizable Filter Press Systems Designed for High Efficiency and Easy Maintenance.
Product Overview
Handling sludge and wastewater from stone production is a common and often challenging task for granite and marble plants. Over time, stone sludge can clutter workplaces, increase disposal costs, and create environmental compliance issues. Our filter presses offer a practical, durable, and cost-effective solution for stone waste management. Each system is built with a heavy-duty frame and wear-resistant filter plates, designed to withstand the erosion from abrasive materials like marble, granite, and quartz. An advanced hydraulic system delivers constant pressure and rapid dewatering, resulting in dry filter cakes and reducing both transportation and water recycling costs. The fully automated operation frees up your team, while user-friendly controls make routine maintenance and cleaning straightforward for any operator.
Core Advantages
  • Workshop Cleanliness & Safety: Removes up to 99% of solids from stone cutting and polishing wastewater, maintaining a tidy environment and improving workplace safety.
  • Lower Handling Costs: Drier filter cakes mean less weight and lower disposal expenses per truckload.
  • Engineered for Stone: Built to handle abrasive powders and chemical additives typical in stone processing water.
  • Flexible Capacity: Available for both small workshops and large-scale stone production plants.
  • Compliance Assured: Designed to meet strict local and international wastewater discharge and recycling regulations.

Buyer FAQ

What plate size is typical for a stone processing plant?

Small workshops usually run 800–1000 mm plates; mid-size and large plants run 1250–1500 mm. The right size depends on cubic metres of slurry per day and its solids content, which a short filtration test on your slurry will confirm.

Do I need a thickener or settling tank before the press?

Yes in most plants. Stone wastewater is dilute, so a settling tank or thickener with flocculant brings solids up to a level the press can fill efficiently and cuts cycle time.

How is the stone cake disposed of?

At 20–30% moisture the cake is dry enough to truck to landfill or to reuse as fill or a raw material for bricks and cement; it does not drip, so it can be stockpiled under cover.
