SAG Mill Products
forged grinding steel ball
Honwa aims to provide proposals for first-time mill balls loading, upper adding method and management. Try our best to improve the performance of clients’ grinding circuit. We deliver the size, grade and chemical composition in our grinding media according to a processing plant’s ore characteristics, milling methods, and other objectives.
★ Quality Control by Smart Equipment
Honwa is always committed to researching and developing new production methods and equipment, to reduce the manual causal influence on the production process and quality. Our equipment can automatically lift bars, heat, forge, separate, and do the heat treatment process.
Meanwhile, all figures can be recorded automatically, including how many pieces of bar material, every part of heating data, forging times, ball pieces, heat treatment temperatures in quenching, cooling, tempering. Every process point has its abnormal alarming system, including bar accurate location, ball forging trajectory, gaps between each ball to control the temperatures.
★ Make the First Ball Same as the Last
The ball size is of vital importance to the fineness of output to the end-users. Larger grinding media has a smaller grinding surface area but offers a heavier weight that’s generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. With smart equipment, we can maximize our sizing to make the first ball the same as the last one and optimize ball size according to the operation.
★ Even Wear
Our technical team always focuses on even wear ball by balancing hardness and toughness according to the milling targets in the operational plan. Surface hardness may only result in a few hours of good performance while linear hardness will produce consistency throughout the balls’ deployment. The even wear allows for the new life potential of media rejected from ported SAG mills. The rejects are totally recyclable since the media retains their integrity for ongoing deployment in a secondary mill. Recycling to a ball mill as supplementary media or possibly as resale to other users provides additional value for our clients.
★ Focus on Microstructure
We check every batch of material by an ultrasonic detector to ensure the hydrogen content of hot rolled bar;
We utilize high ratio upset forging to make balls’ microstructure tougher and finer;
We monitor heat treatment to lock the right microstructure at the right temperature;
We perform ball drop tests of each batch with consistency to ensure performance.
We slice balls into pies to analyze its microstructure, grain size, and hardness.
★ Automatic Ball Feeder
● Reduce labor cost;
● Regular the ball feeding to avoid “Swelling” or “Starvation”(Adjustable)
● Optimize the fineness of output. Without ball feeder, every minute that you feed the ball, ore will bear more impact energy hence to make it over breaking.
● Optimize the ball size matching in the mill. Ball size will be in a perfect size gradient.
● Automatically record ball feeding pieces to make end users work easier.
