ViTech Corporation,
ViTech Corporation, is Pioneer in manufacturing’s proprietary design is based on a rubber/fabric outer case and elastomeric inner lipintegrally molded to form a leak-free bond. A stainless steel garter spring provides the correct interference with the rotating shaft for an effective seal.
ViTech Corporation, is Expertise and Experience in developing products for OEM and Plant application. More than 35% of Produce quantity is supplies to major of Cement Plant manufacturer, our major are FLS, KHD, Fives, Brevini, Lafarge ItalCementi, Holcim etc.

Applications in Cement Plants
Crusher
Heavy Duty Application
Mill Main Gearbox
High-performance sealing
Kiln Support Roller
Extreme temperature durability
Roller Press Seal
Heavy load sealing solution
Crusher Process Flow
Blasting
Raw materials are blasted from the quarry.
Transport
Materials are loaded into dumpers.
Crushing & Transport
Crushed materials are transported via conveyor.
Raw Grinding and Burning
Raw Grinding
The raw materials are finely ground to produce the raw mix.
Burning
The raw mix is preheated and burnt in the kiln at ~1500°C producing clinker, which is rapidly cooled with air fans.
Grinding, Storage & Dispatch
Grinding
The clinker and the gypsum are very finely ground giving a “pure cement”. Other secondary additives and cementations materials can also be added to make a blended cement.
Storage, Packing & Dispatch
The cement is stored in silos before being dispatched either in bulk or in bags to its final destination.
Gearbox’s Seal
Kiln: Support Roller Application –Only Split is the solutions, previously customer was using felt packing, with few customer, converted will Split Seal.
Main G.B. Application: Due to heavy coupling and motor is install, its very difficult to replace the seal, for such app. We have convince our customer to go for Split design seal.

Split Seal : Installation Pattern
Advantages of Split Seal
- Saves costly downtime, speeds repairs
- Easy installation with no special tools
- Stainless steel garter spring keeps split junction tight and compensates for minor shaft irregularities
- Flat lip contact design compensates for minor split-end misalignment
Split Seal : Installation Tips
Step 1
Prepare the shaft and housing for seal installation.
Step 2
Place the seal halves around the shaft carefully.
Step 3
Check alignment and tighten screws partially.
Step 4
Put the end cover in position on the housing wall using screws. Tighten opposite screws together until the cover abuts the housing wall.
