AIA/VEGA manufactures High chromium cast grinding media which is wear, corrosion and impact resistant helps in efficient ball mill grinding.
Our grinding media is tailor made for each milling application. There is a wide range of alloying options which are decided after adequate test work and technical analysis. We manufacture grinding media with chrome content ranging from 3 % to 33 % in sizes ranging from 12 mm to 125 mm as required by the application.
Enhanced profitability of mining companies is assured with Vega high Chrome grinding media solutions.
Shell liner design is critical aspect to facilitate efficient mill performance along with higher mill availability.
Vega’s design objectives:
The design is based on multiple parameters such as ore quality, feed size, required product, grinding media size and media/pulp volume.
Our design objective is to ensure feed end liners match life of shell liners to reduce multiple mill stoppages.
The discharge end liners include pulp lifters and grates (slotted plates) have a pivotal role in SAG mill operation for optimum particle breakage rate, slurry discharge rate, eliminate flow back and slurry pooling. This results into improved performance.
Vega offers its state-of-the-art pulp lifters which are designed using patented EEPL technology for improved grinding efficiency in SAG /AG mills. Our offerings also include conventional radial or curved pulp lifter.
Vega offers optimized Cr-Mo steel and martensitic steel alloys for lining system.
It utilizes an advanced model to predict the motion of the outermost grinding media in a rotary grinding mill. MillTraj provides-
The Discrete Element Method (DEM) is a numerical technique for predicting the behavior of bulk solids. DEM modelling of tumbling mills reveals the characteristics of the mill media motion, predicting the wear of lifters, and energy consumption under various conditions. It helps in simulating several features of SAG mills and AG mills.
Vega offers optimized Cr-Mo steel, martensitic steel and white iron (16 -25% Cr) alloys for Ball Mill Lining System.
Vega offers optimized Cr-Mo steel, martensitic steel and white iron (14 – 26% Cr) alloys for Rod mill lining system.
These types of mills are common for fine grinding in mining plants. Vega/AIA provides a customised liner solution for better life in mono metal and Sinter cast solutions.
Charge motion and Material transport are PILLARS for Efficient particle breakage.
SAG MILL: Get highest life and performance than any other pulp lifter design available in Mining Industry.
• Increase SAG throughput upto 20%
• SAG Power saving upto 20%
• Finer T80/ steeper particle size distribution
• Improved wear life of mill internals
• Lower circulating load in ball mill circuit
Ball mill – From Overflow to EEPL system.
At Vega, our endeavour is to deliver a pioneering solution to the mining industry to tackle modern mining challenges through MillART technique in combination with ball mill conversion to EEPL system.
Ball mill conversion project involves installing grates and EEPL system at the discharge end which facilitates flow through grates with a higher hydraulic gradient. Efficiency of ball mill operation increases substantially due to improved mineral particle breakage rate and slurry discharge.
Vega’s custom design liner with EEPL as comprehensive solution guarantee the substantial operational profitability.
VEGA is the only company globally that offers MillART which is an innovative and holistic solution resulting into improved liner life, better mill output, energy savings and mineral recovery benefits.
Mill Liner Life
Vega’s High Chrome potential in creating a strong impact on improving the grinding conditions, suitable for high flotation performance is realized with the following case.
VEGA successfully completed trial for SAG mill for a large Gold Mine in West Africa by installing Energy Efficient Pulp Lifter (EEPL) as against existing Curved Pulp Lifter in 2019.
VEGA successfully converted an overflow ball mill to grate discharge ball mill by installing Energy Efficient Pulp Lifter (EEPL) at an iron ore mine located in INDIA.
AIA Engineering and Vega Industries believe in strategic global partnerships to further innovations, improve quality and provide holistic services to our client.
EEMS ( Energy Efficient Milling Solutions) LLC Has deep expertise in providing energy-efficient solutions to de bottleneck and improve performance of AG/SAG/Ball mill circuits to the mining industry. This US based partner has expertise in simulations of grinding circuit. They have even designed the innovative and unique EEPL (Energy Efficient Pulp Lifter) liner design through a holistic approach of mill study.
