Customer Case Study: Ceramic Glaze Slurry Dewatering Project at a Ceramic Tile Factory in India
Customer Background
The customer is a medium-sized ceramic wall and floor tile manufacturer located in Gujarat, India, with an annual production capacity of approximately 50,000 square meters per month. During production, the factory generates large quantities of ceramic glaze slurry and ball mill cleaning wastewater. The customer needed to recover solid materials from these streams for reuse while simultaneously reducing wastewater discharge.
Challenges
- Generated approximately 4–5 tons of glaze slurry per day with an initial water content of about 70%
- The slurry contained recoverable ceramic raw materials; direct disposal resulted in significant material waste
- The existing plate and frame filter press was outdated, with slow filtration speed and a filter cake water content as high as 40%
- High filter cake moisture content led to increased energy consumption and longer processing times during the subsequent drying stage
- Required a replacement equipment with higher filtration efficiency and moderate operating costs
Solution
In August 2024, the customer purchased one unit of the XMY30/630-30 Automatic Hydraulic Chamber Filter Press for solid-liquid separation of glaze slurry and ceramic raw material recovery. The configuration is as follows:
| Parameter | Specification |
|---|---|
| Filtration Area | 30 m² |
| Filter Plate Size | 700×700mm, PP material, corrosion-resistant |
| Filter Cloth Model | 750AB, suitable for fine ceramic particle filtration |
| Operation Mode | Automatic hydraulic tightening + manual plate pulling |
| Discharge Type | Dual open flow for easy observation of filtrate clarity |
Operational Results
After installation and commissioning, the equipment has been in operation for two months. Actual performance data is as follows:
- Single cycle time: Approximately 1.5–2 hours
- Batches per day: 4–5 cycles (based on 8-hour workday)
- Slurry volume per batch: Approximately 1.2–1.5 tons
- Filter cake water content: Reduced from 70% to 25%–28%
- Dry solids recovered per batch: Approximately 0.8–1.0 tons
- Filtrate clarity: Suspended solids content below 0.5%, suitable for direct reuse in ball mill cleaning
Customer Feedback
"After installing this XMY30/630-30 filter press, our glaze slurry processing efficiency has nearly doubled compared to our old equipment. The filter cake water content has dropped from 40% to about 26%, reducing drying time by 35% and significantly lowering natural gas consumption. More importantly, we recover approximately 3–4 tons of ceramic raw materials every day, which are directly returned to the production line. This saves us about 40,000 rupees per month in raw material costs. The equipment is easy to operate, the hydraulic tightening force is uniform, and filter cloth cleaning is convenient. For slurry dewatering in the ceramics industry, this equipment has exceeded our expectations."

Applicable Scenarios
This case study demonstrates that the XMY30/630-30 filter press is also well suited for:
- Dewatering and raw material recovery from ceramic glaze and clay slurry
- Solid recovery from ceramic tile polishing wastewater
- Solid-liquid separation of non-metallic mineral slurries such as kaolin and feldspar
- Slurry concentration in the paint and pigment industries
