Belt Fastening Screw and Steel Belt Lacing Rivet Type Belt Joints

Introduction

1. It is Available for All Conveyor belt grade abrasion resistant, heat resistant, heat retardent, fire resistant.
2. Temperature No issue which can go high up to 220 deg. C .
3. High moisture or water can also come on to the conveyor belt during operational abnormalities or Variations. Joint will have no issue
4. Expected life of this joint is high in comparison to other joints mainly in HOT BELTS Or High Temperature Regions.
5. The warranty of this joint as per the real data at places where it has been installed has given good life.

In hot areas where Temperature is around 180 -220 Deg C at those places these joints are giving Life much much more then the regular joints.

6. It is feasible for all type of scrapper’s like Primary, secondary Scrappers.
7. No tension for the Life of the Super Screw materials as these can be kept in stock for years.
8. Reduces 90% Spillage as compared to Other Mechanical Joints.
9. No restriction to Length across width.
10. Available from EP 200 to EP 2500 strength belt.

In General

  • Conveyor Belts Grades (Abrasion Resistant, Heat Resistant, Super Heat Resistant, Fire Resistant, Wear Resistant etc.)
  • For Super Heat Resistive and Heat Resistive the Flexi Screw Joint can tolerate more than 220 Degree C.
  • Joint will not have any issue with high moisture on conveyor belt.
  • Expected life of the Flexi Screw joint is very high as compared to other joints specially at High Temperature Regions. (In hot areas where temperature is 180- 220 Deg C at those places the Flexi Screw Joint life is better than any other joints.)
  • It is compatible with all types of Scrapers such as Primary and Secondary Scrappers.
  • Reduces 90% Spillage problem as compared to Mechanical Fasteners.
  • Available from EP 200 to EP 2500 strength belt.
  • Battery operated drill machine is also provided with it in the kit itself.

We offer All Rubber Flexi screw lacing fastener system for Belt joints

Various joints has carried by us at various customer places at Birla corp., HZL Chanderia etc

Battery operated screw driver machine for joint making. We have trained team for carrying the joint on short notice. Our team and material at Chittogarh for on call service support.

It takes 1 hr max to make a joint. Does not require heavy hot splice machine. Normally RP feed n bottom belts are with small c-c and once first joint gets opened , the length is short to make next joint as hot joint consumes approx 2.5 to 3 mtr belt length. This joint consumes only 265 mm and so you can make minimum 6-8 joints again if belt conditions are good.

Images of belt joint 1600 mm , 2200 mm and 2400 mm at JK cement NIMBAHERA, ULTRATECH cement plant RP feed and discharge belt applications.

Note

1. Flexi screw joint only takes 1 hour for belt jointing as compared to Hot joint process which takes approx. 10 to 12 hours to complete 1 belt joint and approx. 5 to 6 hours with cold joint process.
2. Flexi screw joint only consumes only 265 mm of belt length for joining the belt as compared to Hot Joint process which consumes around 2.5 to 3 M of belt length for joining the belt.

Mechanical Belt Fasteners

Mechanical Belt Fastening is the process of joining conveyor belt ends by metal hinges or plates. Vulcanization is the process of joining belt ends through heat or chemicals.

Mechanical Belt Fastening involves the use of mechanical belt fasteners (also called conveyor belt lacing). Mechanical belt fasteners combine strength and durability with affordability and easy installation.

Heavy-Duty Belt Fastener Types

In heavy-duty applications like coal, cement, mining, and aggregate, there are two main belt fastener types: Hinged Plate and Solid Plate. Hinged plate fasteners, often used with small pulleys, are installed into each end of the belt and then joined together and held in place with a pin. Solid plate fasteners consist of one plate that is installed into both ends of the belt and fastened together. Solid plate fasteners are used with larger pulleys and for applications that require a sift-free splice. These fasteners are installed into the belt using bolts, rivets, or staples (depending on belt type and application) and are available in a variety of metals.
