THE HISTORY OF BELT IS THE HISTORY OF BANDO Bando Chemical Industries Ltd owes its name and origins to the inventor Mr. Naosaburo Bando. During the 1890’s, Mr. Bando began research to develop an original type of industrial belt. After 10 years of extensive research he succeeded in designing a new belt, the first of its kind in Japan. This new belt was patented as BANDO BELT (Japanese Patent No. 3384).
PT. BANDO INDONESIA With a rich and tradition behind us, PT. Bando Indonesia is today the leading manufacturer of conveyor belt in Indonesia. PT. Bando Indonesia is a joint venture manufacturing company between PT. Kreasi Utama Investama and Bando Chemical Industries, Ltd. Japan, which is one of the world’s leading integrated manufacturers of rubber belts since 1906. Since our establishment in 1987 in Indonesia, we have continually innovated and developed our products to earn our customers’ satisfaction.

Bando Chemical Industries Ltd owes its name and origin to inventor name Mr. NAOSABURO BANDO. In 1890’s, Mr. BANDO began to conduct research to develop an original type of industrial belt. Finally, after ten years ( 1900 ) Mr. BANDO held and extensive research and succeeded in inventing a new belt, which was named the BANDO BELT, and protected by a patent. ( Japanese PAT. No. 3384 ) as the first belt of its kind of belt in Japan.

Application for low medium temperature
This standard heat-resistant belt is made of SBR polymer and is highly abrasion resistant. It can consequently be used as a subsitute for ordinary belts in addition to its special applications.
for low medium temperature
This heat-resistant belt is made of SBR material. It is less abrasion resistant but more highly heat resistant than the heat-resistant No. 510. It is suitable for materials highly sensitive to contamination.
for high temperature
This noncrack model is made of EPR polymer and is highly resistant to thermal degradation. It is suitable for high-temperature applications and is abrasion-resistant.
for medium temperature
This noncrack white belt is made of EPR polymer is suitable for materials highly sensitive to contamination.
1. The temperature of material being transported and the belt’s surface temperature vary according to the
Cautions
material and shape. For instance, when materials have a temperature 150 0C (300 0F)(such as coke or sintered ore) and have a relatively small contact area with the belt the belt’s surface temperature remains at 60 ~ 80 0C (140 ~ 180 0F). In contrast, when powdered material like cement is being conveyed, the material temperature and the belt temperature do not differ so greatly.
The life of a heat-resistant belt is largely affected by belt’s suface temperature during operation.
Therefore, pay closer attention to the surface temperature than the conveyed material when selecting a belt.
2. Restrictions on the use of heat-resistant belt
Restricted applications (Applications that should be avoided)

SKIRTING RUBBER Application
Conveyor Belt Skirting Rubber is a specifically designed rubber sheet used as sealing strip on conveyor system loading, transfer and discharge points. Skirting rubber is used to direct material onto the conveyor belt and reduce spillage.
Features
At PT. Bando Indonesia we produce a full range of skirting rubber including full slabs up to 2200 mm wide and a range of pre-cut skirting rubber strips in a variety of thickness. Custom width strips can also be supplied as per customer requirements.
Construction
Bando Skirting Rubber is specially designed with hardness (duro) 55 with tolerance ± 5, which is lower than the common hardness of conveyor belt.
20
PULLEY LAGGING Application
Lagging is the term used to describe the application of a coating, cover or wearing surface which is applied to pulley shells.
Features
Rubber lagging is applied to pulley shells in order to improve the friction between the pulley and the belt. PT Bando Indonesia produce a variety of rubber lagging patterns: Plain, Stripe and Diamond pattern, with a full range of widths and thickness up to 2,200 mm width and 30.0 mm thick. ( ± exclude Diamond Pattern).
Construction
Diamond grooved lagging refers to the pattern in the lagging and this pattern, similiar to vehicle tires, enhances the grip or friction even if the belt surface is dirty. Plain lagging is applied to pulleys which are not drive pulleys for example tail pulleys, take-up pulleys, etc. but which require good traction between belt and pulley for improved belt tracking capability.

SUNPAT-ECO VULCANIZING MATERIAL AT ROOM TEMPERATURE Application
This is adhesive for vulcanizing rubber at ambient temperature, used for the splicing and repair of conveyor belts.
Features
1. Shorter Curing Time The belt can be in operation only two hours after work is completed. (with ambient temperatures over 15 0C ~ 35 0C). 2. Wider Applicable Range SUNPAT-ECO is also applicable to SBR type heat resistant belt and oil resistant belts. 3. High Peeling Off Resistantce Even though cushion rubber is not used is hightly resistant to peeling off caused by bending. 4. Operational Efficiency is increased With its quick drying performance yet high adhesion it eliminates problems such as mis-positioning. Finishing is also simple. Products name

Construction
Standard structure of BANDO STEEL CORD CONVEYOR BELT is of all rubber type and is designed as follows : The steel cord is of high quality carbon steel ( 6.65%-0.75% ) and coated with zinc for protection from corrosion. For normal applications steel cord with low bending fatigue, such as 7XW19 is used. 7X7X7 is also available, depending on the particular application.

TAKE-UP STROKE When deciding on the take-up stroke it is necessary to consider both elastic elongation and permanent stretch.
TAKE-UP STROKE ( Percentage of Center-to-Center Distance ) Kind of carcass
Elastic Elongation
Permanent Stretch
Take-up Stroke Recommended
NN100 ~ 350
0.3 ~ 0.5
1.0 ~ 1.2
1.7 + Additional length
NN400 ~ 630
0.4 ~ 0.8
1.0 ~ 1.2
2.0 + Additional length
EP
0.1 ~ 0.3
0.4 ~ 0.6
0.9 + Additional length
Additional length = Spare length + Initial stretch ( Initial stretch : Approximate 0.5% )
Spare length equals a half of a splicing length or 2 ft ( 500 mm ) whichever is longer, plus 0.2% of the center-to-center distance with a minimum of 6 inches ( 150 mm ) and a maximum of 40 inches ( 1000 mm ). The former provides sufficient length in case resplicing is required due to an accident or mishap. The latter is considered necessary to provide the slack in the conveyor line which is required during splicing work and is afterwards absorbed into the take-up
Limit Spare length
