Quality

The quality of our products is a resultant of the concerted team efforts of our qualified engineers, strict quality control

measures accompanied with the use of the best materials and, above all, updating the technology.

Automation, instrumentation and computerized controls bring about quality controls, operational optimization, enhanced

productivity and operational cost benefits. Our plants incorporate the newest developments, adhere to the latest

international standards and are environment-friendly in terms of dust emission and noise levels.

Infrastructure

Our manufacturing facilities incorporate state-of-the-art and innovative machinery and equipment to ensure a high quality

in all our products. We are also dependent on a dedicated and qualified team of professionals and support staff that

executes the challenging jobs as per organizational needs.

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 theirfully-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 kilns 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 avoidingpossibilities of slippage due to presence of large air film between

roller surface and web.


6/9

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 systemRotary 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 wearresistance

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
