Ball mill Liner Ball mill linings from dajia-engineering protect your mill from the abuses of mineral processing while allowing high grinding and crushing efficiency. Our ball mill linings are designed from rubber or casting steel or rubber composite materials according to your application and throughput requirements.
Rotary Kiln tyres (Rings) The purpose of tyres (often called riding rings) and rollers is to support the kiln and allow it to rotate with minimal friction. Rotary kilns are among the largest items of permanently moving industrial machinery, the largest examples weighing in their fully-loaded form several thousand tonnes. Despite the challenges of their size and their high temperature, the best examples of rotary kiln rotate on their rollers almost frictionlessly, the power supplied by the drive being almost entirely in order to oppose the eccentric load of the contents of the kiln. On cutting the power to a kiln, the kiln will “roll back” and unless a brake is applied, will continue to swing like a pendulum for ten or fifteen minutes before coming to a standstill. This finely-tuned mechanical condition requires sophisticated design of the kiln’s supports. A standardised design evolved during the first three decades of the twentieth century, allowing the great escalation in size of kilns that then followed. Kiln Support Roller Kiln Support Rollers are backed by latest technology and provide desired support to cables and other related products. These support rollers are driven to rotate using friction between roller surface and web. The small friction torque of the roller bearings also allow higher speed operations and helps in avoiding possibilities of slippage due to presence of large air film between roller surface and web.
Features: Coming with small friction torque of roller bearings Rollers are close together that decrease pulling tension Manufactured as per defined industry standards Can also be custom designed as per client's specific requirements Durable finish and reliable performance Mill Girth Gears Mill Girth Gears comprise high integrity girth gears that find application in driving horizontal grinding mills. With these gears developed for achieving superior finish strength and process reliability, these can be designed for different kW applications as well as in diameter and weight choices. For ensuring in them flawless finish support, we manufacture them in temperature controlled environment. Applications: Girth gears mainly using in Ball Mills Kiln drive system Rotary Dryer Steel re-rolling mills Paper industries Rod Mills
Ring Gears Ring Gears are also known as starter ring and comprises medium carbon steel ring with teeth which comes fitted on periphery of flywheel of internal combustion engine generally in automotive applications. With the teeth driven by smaller gear (pinion) of starter motor, its primary use is in transferring torque from starter motor pinion to flywheel/flexplate for engine rotation. Features : Starter ring gear featuring precision construction support These are made to undergo different heat-treatment including tempering, normalizing and others for precision finish Teeth of starter ring hardened for enhancing its strength and wear resistance Modern computer aided designing support using software like AUTOCAD, SOLID WORKS for ensuring precision construction standards Interference checks and dimensional accuracies carried out using these tools Can also provide load analysis & stress analysis on gears using finite element analysis Application : These are mostly used in automotive applications including: Rotary Dryer Rotary Cooler Kiln Three drum dryer Ball mill
