1. Overview
Shanghai Junyi Filtration Equipment Co., Ltd. recently completed in-depth technical and commercial negotiations with Saad Elamary, a granite processing enterprise based in Egypt.
Focusing on the client’s sludge dewatering needs in granite production, both parties finalized two comprehensive solutions—custom filter plates and filter cloths, as well as complete filter press systems—providing a professional answer to the client’s solid-liquid separation challenges in stone manufacturing.
2. Client Background & Operational Pain Points
Saad Elamary specializes in granite quarrying and processing. The cutting and polishing processes generate large volumes of fine granite grinding sludge, which contains abrasive rock powder—resulting in high material wear and high solid content.
Traditional filtration components are prone to damage and suffer from unstable filtration efficiency, creating significant operational pain points. In response, the client proactively presented multi-dimensional procurement requirements:
-
Component Requirements:
870×870 mm chamber-type filter plates, 70 mm thick, along with 30 filter cloths, compatible with existing chamber filter presses for granite sludge dewatering. -
System Upgrade Requirements:
A full set of automated chamber filter presses for future expansion—specifically a 1000×1000 mm model equipped with 30 filter plates and an automatic plate-pulling mechanism. The client specified that the equipment should not include a feed pump, aiming to expand granite sludge processing capacity.
3. Technical Solutions Provided
Upon receiving the inquiry, our technical and sales team promptly analyzed the operating conditions.
For the component replacement (870 mm system):
Given the highly abrasive nature of granite sludge, we prioritized recommending 70 mm thick, high-density polypropylene chamber filter plates. Compared to standard thinner models, these thicker plates offer:
-
Superior compressive strength
-
Resistance to erosion by hard granite particles
-
Minimized cracking and deformation
The plate design is fully compatible with the client’s existing 870 mm chamber filter press, enabling direct replacement and installation. Additionally, we provided matching filter cloths according to the client’s equipment scale, ensuring:
-
Effective retention of fine rock dust
-
Reduced filtrate turbidity
-
Extended component service life
For the new system upgrade (1000 mm fully automatic press):
We recommended the 1000 mm fully automatic chamber filter press (equipped with 30 filter plates and 50 m² filtration area). Key features include:
-
Automatic plate-pulling and discharge system – automatically completes plate separation and cake discharge, significantly reducing manual labor
-
Configured without a feed pump per customer specifications, allowing seamless integration with the client’s existing pipeline infrastructure and flexible adaptation to site layout
-
Ample filter chamber volume to accommodate large amounts of solid residue from granite sludge, producing low-moisture filter cakes that facilitate subsequent waste transportation and disposal
4. Communication & Quotation Process
Throughout the communication process, we provided the client with:
-
Real-time photos of filter plate production
-
Delivery site footage
-
Operation videos of the filter press
-
Complete technical documentation
We issued detailed formal quotations in two stages, clearly outlining configurations and commercial terms for both:
-
The 870 mm filter plate + cloth kit
-
The 1000 mm fully automatic filter press solution
We continuously updated product details and patiently addressed all client inquiries.
5. Expected Application Benefits
Once deployed in the Egyptian granite processing plant, the complete filtration system will:
-
Efficiently treat sludge wastewater generated during stone grinding
-
Convert solid stone powder into dry filter cakes for easy recovery and disposal
-
Enable clean water recycling, helping customers meet local environmental discharge standards and reduce water consumption
The combination of thickened filter plates and specialized filter cloths reduces frequent replacement costs, while the fully automatic plate and frame filter significantly saves labor time for unloading. This enhances the continuity of the entire stone processing production line and enables customers to achieve cost reduction and improved efficiency.
