Location: Surabaya, Indonesia
Material: Limestone
Feed Size: <25 mm
Product Requirement: 325 Mesh (45 microns), meeting D90 standards
Required Output: 18–20 tons/hour
Core Equipment: 4R3220 Raymond Mill
Client Challenges
The small-scale grinding mills previously used by the client suffered from the following issues:
Excessive Energy Consumption: Traditional Raymond mills consumed an excessive amount of electricity per ton of processed material.
Inconsistent Fineness: The classifier exhibited low separation efficiency, resulting in coarse particles being mixed into the final product.
Frequent Maintenance: The grinding shovels and rollers experienced rapid wear, leading to prolonged downtime for maintenance.
Solution
Based on the client’s specific requirements, we recommended the 4R3220 Raymond Mill system. The technical highlights of this solution include:
Integrated Bevel Gear Drive: Transmission efficiency is increased by 20% compared to traditional belt-driven systems.
Thin Oil Lubrication System: Eliminates the tedious task of manual lubrication and extends the service life of the bearings threefold.
Curved Air Duct Design: Reduces airflow resistance and enhances airflow conveying efficiency.
Client Testimonial
“Since upgrading to this 4R3220 Raymond Mill production line, our operating costs have decreased significantly. In particular, its automatic fineness adjustment feature provides us with immense flexibility when fulfilling orders with varying specifications. Furthermore, we were deeply impressed by the professional installation services provided by the after-sales support team.”
