Working condition corrosiveness: High purity white corundum ceramic filter plates are preferred for high acidity/high corrosiveness slurries (copper ore, lead-zinc ore); Ordinary low corrosion working conditions can choose brown corundum filter plates with higher cost-effectiveness.
Installation site: Choose vertical/horizontal structures according to the height of the factory and the size of the site, and reserve space for lifting and maintenance in advance.
2. Compare the quality of core components and focus on technical indicators
The quality of core components directly determines the service life and filtration effect. When selecting, it is important to verify:
Ceramic filter plate: Priority should be given to products that are sintered and formed as a whole, and check if there is a formal material testing report to avoid adhesive splicing products that are prone to cracking;
Vacuum system: Priority should be given to equipment equipped with water ring vacuum pumps, with a stable vacuum degree of -0.09MPa or above, which is higher and more stable than reciprocating pumps;
Cleaning system: equipment with ultrasonic and automatic backwashing combined cleaning, which can reduce manual maintenance frequency and extend the service life of filter plates.
3. Prioritize manufacturers with successful industry cases
Require manufacturers to provide successful cases in the same industry and under the same working conditions, preferably by conducting on-site inspections of the actual operating effects of the equipment. For example, for mining beneficiation, priority should be given to manufacturers who have served leading enterprises such as Zijin Mining and Aluminum Corporation of China;
For overseas project selection, priority should be given to manufacturers who provide spare parts warehousing and localized services in the country where the project is located, which can significantly shorten the response time to failures.
4. Verify the manufacturer's qualifications and service capabilities
Preliminary screening of reliable manufacturers based on public information:
Priority should be given to high-tech enterprises that have passed ISO9001 certification, as these manufacturers have more standardized quality control measures;
Confirm service content: Priority should be given to manufacturers that provide free installation and debugging, personnel training, and hosting operation and maintenance. They can be on-site for repairs within 1000 kilometers 24 hours to avoid the inability to find after-sales service after a malfunction;
When signing the contract, it is important to specify key terms such as the warranty period and repair response time for ceramic filter plates to avoid disputes in the future.
5. Beware of the low price trap and pay attention to the full lifecycle cost
Don't just look at the initial purchase price. Some low-priced equipment may use inferior filter plates and accessories to reduce costs. Although the purchase is cheap, the lifespan of the filter plates is shortened by half, and the total cost of frequent replacement is higher; Prioritize selecting manufacturers that can provide full lifecycle cost estimation, and comprehensively compare the total cost of initial procurement and later operation and maintenance.
