Grinding Media
Steel ball, as the indispensable consumable to ball mill, is a kind of wear-resistant material that made of carbon, chromium,
manganese, and molybdenum, etc. as the main added metal elements, and can be produced through forging, spinning,
rolling, grinding and casting.

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.
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.
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
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
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
Three drum dryer
