Lifter Bar ( Trapezoidal)
Kedar Rubbers offers high quality rubber products including the best quality Lifter Bars (Radial and Trapezoidal), which are essential components of ball mills. Our top-quality lifter bars play an important role in making grinding processes efficient by improving the grinding media and materials’ tumbling action.
Thus, the key functions of lifter bars are to lift the grinding media and materials that ease the movement, protect the mill shell, reduce the noise level, and enhance the grinding & milling efficiency. Selecting the right dimensions and designs of lifter bars can significantly impact the performance and cost-effectiveness of the milling process.
Uses
Our lifter bars comprise excellent resilience and wear resistance and are broadly used in different milling applications in industries, such as Mining, Metal, Cement, and Ceramic where it is required to deal with hard ores or abrasive materials.
At Kedar Rubber, we deliver radial and trapezoidal lifter bars based on precise customer specifications (design, height, angle, radius, etc.). We provide the best quality lifter bars according to the customized needs of your milling processes to lift and drop the grinding media.
Trapezoidal Lifter Bars
The trapezoidal profile plays a vital role in making the grinding process efficient by influencing the movement of grinding media and material in the ball mills. They improve the lifting action using higher and angled edges that give an aggressive lifting angle compared to rectangle lifter bars. It allows lifting the charge towards the up direction within the mill and then letting the balls and material drop from the top of height to create higher impact pressure. Thus, such actions make the grinding process more efficient for breaking down material.
Besides trapezoidal lifter bars boost the dropping motion necessary for properly mixing and uniformly distributing the grinding media and material throughout the ball mill. Thus, it well-manages the motion that improves the milling process by increasing the contact between the material and balls which results in reducing particle size consistently. They require less time to process significant amounts of material.
All About Lifter Bars - With & Without Metal
At Kedar Rubber, we provide lifter bars with and without metal based on the tailor-made needs of customers as per their milling applications.
Lifter Bars with Metal
Lifter bars with metal are best applicable in ball mills for their utmost durability, and capability to withstand the intense wear and impact due to abrasive and hard material grinding, thus offering primary grinding benefits. They can manage abrasive materials and high-impact forces. The superior lifting capability of metal lifter bars enables maintaining a continuous and effective trajectory for the ball mill’s grinding media. This improves the quality of the products, grinding performance, and higher materials.
Lifter Bars without Metal
With some characteristics like energy efficiency and noise resistance, Lifter bars without metal are best applicable for fine and secondary grinding applications of ball mills. As made from rubber, non-metal lifter bars reduce energy consumption as they decrease the load on the motor. They are suitable for regrinding (secondary) grinding, where they require low-impact force and minimize wear and tear. Thus, lowering the operating cost and increasing the lifespan of equipment.

FAQ
1. What is a Lifter Bar (Trapezoidal)?
A Lifter Bar (Trapezoidal) is a specially shaped rubber or rubber–metal composite component used in ball mills and grinding mills to lift and cascade the grinding media efficiently. Kedar Rubber Products Pvt. Ltd. designs and manufactures high-performance trapezoidal lifter bars for improved grinding efficiency and wear protection.
2. What is the function of a Trapezoidal Lifter Bar in a Ball Mill?
The trapezoidal lifter bar lifts the grinding media during mill rotation, creating cascading motion for better impact and grinding action. Kedar Rubber Products Pvt. Ltd. ensures precise shape and durability to optimize mill performance and energy efficiency.
3. What are the benefits of using Kedar Rubber Products Pvt. Ltd.’s Trapezoidal Lifter Bars?
These lifter bars offer excellent impact resistance, reduced noise, lower maintenance, and longer service life. The trapezoidal profile provides better material lift and discharge, improving grinding output and reducing liner wear.
4. What materials are used in manufacturing Lifter Bars?
Kedar Rubber Products Pvt. Ltd. manufactures lifter bars from premium natural rubber, synthetic rubber, and rubber–metal composites. The steel or aluminum backing ensures mechanical strength, while the rubber absorbs shocks and vibrations effectively.
5. How do Trapezoidal Lifter Bars differ from other liner profiles?
The trapezoidal design provides a unique geometry that enhances media trajectory and material movement, leading to improved grinding action compared to flat or wave-type liners. Kedar Rubber Products Pvt. Ltd. customizes the design based on mill size and operating conditions.
