Customer background
The customer is a ceramic production enterprise located in Mexico, mainly producing floor tiles and wall tiles. The factory generates a large amount of ceramic slurry and ball mill tail slurry every day, with a moisture content of over 75%. Traditional filter presses have difficulties in discharging and the filter cake has unstable moisture content. Moreover, the equipment gets severely rusted in the humid and corrosive environment, which affects production efficiency and product quality.
Customer pain points
Low discharging efficiency: The original manual plate-pulling filter press requires manual pulling of each plate, and each batch of discharging takes more than 40 minutes.
The filter cake is severely adhered: The ceramic clay has a high fineness, resulting in a tight adhesion between the filter cake and the filter cloth. The discharge is incomplete, and manual removal of the cake is required frequently.
Rust on the rack: The slurry contains a small amount of acid and alkali regulators. The surface of the ordinary carbon steel rack is severely rusted, which affects the service life of the equipment and the hygiene of the workshop.
Insufficient moisture content: The moisture content of the filter cake remains at approximately 28%, exceeding the requirement of the subsequent drying process (≤22%)
Solution
After comparing with several suppliers, the customer chose the 870 type one-time opening fully automatic box-type filter press recommended by us, and configured the following scheme:
One-time hydraulic system activation: The hydraulic station drives the entire filter plates to be pulled out at once, reducing the single batch pulling time to 8 minutes.
Vibration plate device: Automatically vibrates during discharging, assisting in the rapid detachment of highly viscous ceramic filter cakes.
Frame 304 stainless steel coating: The outer layers of the main beam, cylinder base and tail plate are all coated with 304 stainless steel to prevent the splashing of corrosive liquid from the slurry.
Usage effect
After the equipment was installed, debugged and operated stably for six months, the customer reported significant results:
In terms of the unloading time, the single batch time has been significantly reduced from the original 40 to 45 minutes to 8 to 10 minutes, resulting in a notable increase in production efficiency.
In terms of the moisture content of the filter cake, it decreased from 27% to 30% before the renovation to 19% to 21%, fully meeting the requirement that the moisture content in the subsequent drying process should not exceed 22%.
In terms of the service life of the filter cloth, the replacement cycle has been extended from every 15 days to every 45 days, resulting in a significant reduction in the cost of consumables.
In terms of corrosion resistance of the equipment, the frame was wrapped with 304 stainless steel, and it operated for 6 months without any visible rust. This completely solved the previous rusting problem.
In terms of processing capacity, the number of batches processed per shift has increased from 3 to 4 to 6 to 7, and the production capacity has nearly doubled.
Customer review
This 870 model single-opening filter press has doubled the efficiency of our slurry workshop. The vibrating plate function has truly solved our most troublesome problem of sticky cakes. The stainless steel coating also eliminates the need for rust removal and painting every two months. We will definitely choose this model for the next batch of kaolin production line.
Case Summary
The 870 type single-pull box-type filter press, combined with the vibrating discharge system and stainless steel frame, significantly enhances the production efficiency and equipment durability in scenarios involving high-viscosity and high-humidity materials. It is particularly suitable for applications in the ceramic, mineral, chemical, and food industries where frequent discharging and humid environments are required.
