Mechanical Power Transmission products for Cement Industry

Flexible Gear Couplings

High performance and easy in installation manufactured using fully automatic hobbing machine.

Roller Chain Couplings

Roller Chain Flexible Couplings are compact, long lasting flexible couplings, capable of transmitting relatively high torques with minimum of space consumption

Torque Limiter

Nu-Teck torque limiter is a protective device that limits torque transmitted in a drive system by slipping when torque demand exceeds a preset value as a result of shock loads, over loads, or machine jams.

Sprockets

Nu-Teck Sprocket Wheels are manufactured from quality materials. Teeth are hob-cut for correct tooth form, tooth thickness and profile.

Mechanical Power Transmission Products for Cement Industry

Cement Industry — Critical Applications in Cement & Bulk Material Handling

In a cement plant, power transmission components are subjected to extreme abrasive dust (clinker/limestone), massive starting torques, and 24/7 continuous operation. Failure in a single coupling can halt the entire production kiln, leading to massive losses.

Here is a consolidated list of 20 applications for our Nu-Teck Couplings' Gear, Jaw, Grid, Tyre, Pin & Bush Couplings, along with Heavy-Duty Sprockets in the cement industry.

20 Critical Applications in Cement & Bulk Material Handling

Application-wise coupling reference for all critical drive points across Raw Material Intake, Grinding, Kiln, Clinker Storage, and Packing sections

Application	Nu-Teck Couplings	Description

Raw Material Intake & Unloading — The Entry Point
Wagon Tippler Drive	Gear Pinions & Gear Couplings	Rotate entire railway wagons 180° to unload limestone or coal — gear pinions handle massive tangential loads during the rotation cycle.
Side Arm Charger (SAC)	Gear / Pin & Bush Couplings	Pull and position a string of loaded wagons — high-torque connection for heavy-duty rack-and-pinion or winch drives.
Puller cum Pusher Equipment	Gear Couplings & Gear Pinions	Move wagons precisely into the tippler zone — robust components handle frequent start-stop cycles and heavy inertia.
Primary Jaw / Gyratory Crushers	Tyre Couplings	Absorb the violent mechanical shocks as massive boulders are reduced to aggregate in primary crushing.
Raw Material Grinding & Storage
Vertical Roller Mill (VRM) Drive	Gear Couplings & Gear Pinions	Connect the primary motor to the heavy-duty gearbox — internal gear pinions rotate the heavy grinding table.
Separator Fans	Grid Couplings	Manage the high-speed vibration of the massive fans that sort fine raw meal from coarse particles.
Raw Meal Dosing Pumps	Jaw Couplings	Provide maintenance-free vibration damping for smaller motors that inject additives into the raw meal.
Bucket Elevators	Brake Disc Gear Couplings	Provide fail-safe holding torque on the head-shaft, preventing back-running if power fails.
The Kiln & Pre-Heater Section
Main Kiln Drive	Gear Pinions & Gear Couplings	Rotate the 100-meter rotary kiln — custom-hardened girth gear pinions withstand 24/7 operation in high-heat environments.
Auxiliary (Emergency) Kiln Drive	Pin & Bush Couplings	Connect the backup engine to the kiln to prevent the shell from warping during power outages.
Pre-Heater Cyclone Fans	Tyre / Grid Couplings	Drive the massive Induced Draft (ID) fans that pull 900°C air through the pre-heater tower.
Grate Cooler Drives	Sprockets & Chains	Move the reciprocating grates that cool red-hot clinker as it exits the kiln at 1,400°C.
Clinker Storage & Finish Grinding
Clinker Deep-Bucket Conveyors	Sprockets (Heavy-Duty)	Carry fresh clinker to the storage silos using heat-resistant chains in a high-temperature, abrasive environment.
Cement Ball Mill Drive	Gear Pinions & Gear Couplings	Drive the massive girth gear of the cement ball mill — paired with high-torque gear couplings for continuous operation.
High-Pressure Grinding Rolls (HPGR)	Telescopic Gear Couplings	Allow the rollers to move apart dynamically under hydraulic pressure while maintaining a constant drive connection.
Cooling Water Pumps	Jaw Couplings (Spider)	Drive the pumps that circulate water to the kiln's lubrication systems.
Packing, Dispatch & Auxiliary Systems
Rotary Packer Drives	Jaw Couplings	Synchronize the high-speed rotation of the multi-spout bag filling machines in the packing plant.
Bagging Plant Conveyors	Chain Couplings / Sprockets	Drive the long-distance transport conveyors moving 50 kg bags to the dispatch area.
Palletizing Robots	Tyre Couplings	Provide the smooth, cushioned motion needed for robots to stack bags without tearing or spillage.
Dust Extraction Fans	Grid Couplings	Connect motors to the centrifugal fans that keep the plant environment free of cement and coal dust.

Nu-Teck Customised Gear Couplings, Sprockets & Pinions

In the Cement and Bulk Handling sectors, standard parts often fail due to abrasive dust and extreme operating conditions. Nu-Teck specializes in the following customized products

Coupling / Product Type	Description & Purpose
Nu-Teck Heavy Duty Gear Pinions	Custom-manufactured with induction hardening or case hardening (up to 60 HRC) for maximum wear resistanc e in Wagon Tipplers, Kiln Drives, and Ball Mill Girth Gear applications.
Nu-Teck Labyrinth-Sealed Gear Couplings	Metallic seals create a tortuous path to block fine cement and coal dust from entering the gear mesh grease — essential in RMHS, Crusher, and Kiln drive locations.
Nu-Teck Shear Pin Gear Couplings	Acts as a mechanical fuse for SAC and Pusher equipment — precision shear pins disconnect the drive instantly during jams, protecting expensive gearboxes from catastrophic overload.
Nu-Teck Snap-Wrap Jaw Couplings	Allows replacement of the elastomer spider in minutes without moving the motor or pump — minimising maintenance downtime in dosing pumps, packers, and cooling water systems.
Nu-Teck Chain Sprockets up to 3" Pitch / 2 m Diameter	Heavy-duty sprockets used across all cement plant material handling equipment — grate coolers, clinker conveyors, bucket elevators, and bagging plant conveyors.
