- Industry: Coal Fired Power Plant
- Product: ASGCO® Pro-Zone modular conveyor belt load zone system
- Objective: Provide the latest conveyor technology and engineering to solve a coal dust and spillage environmental concerns and increase productivity.
In today’s coal fired power plants, it is important to keep coal dust and coal spillage in the load zone area to a minimum. Many plants struggle to keep these areas clean, due to not having enough time or man power to properly adjust skirt rubber or fix holes in the chutes. Around many load zone areas you will usually find coal piles in between troughing idlers and on the floor. This coal spillage is expensive to remove and if not properly fixed the coal piles will reoccur again and again. Read more

To contain the fugitive material by reducing airborne dust, controlling spillage and reducing or eliminating housekeeping issues.
This northwestern coal fired power plant was experiencing tremendous amounts of coal escaping through the load zone area. There were several issues that needed attention. The belt was mis-tracking in the impact area of the load zone and it was not fully supported due to impact rollers being used. Both situations resulted in excess spillage and airborne dust. Read more
Conveyor efficiency, safety and productivity are critical components to any mining operations or bulk shipping terminal. Therefore conveyor belt mis-tracking or mis-alignment can be a major concern.
The problem, as shown in the pictures of the right, conventional training idlers are not effective. Some of the problems are; the side-guide rollers and exposed center pivot will seize, which can creates sever belt edge damage, the trainer in most cases is tied off in one direction therefore not allowing the trainer to actuate when need and lastly conventional tracking idlers will not work on reversing conveyor systems. On one particular reversing conveyor system the customer had a conveyor belt mis-alignment switch sending and alarm nearly every day.
After a complete survey of the conveying systems and the biggest problems were identified, it was recommended to the customer that they install ASGCO Tru-Trainer® series of conveyor belt tracking idlers approximately 20’-30’ (7m-10m) prior to any conveyor pulley. After the installation of the Tru-Trainers the customer has not had a single belt mis-alignment alarm on any conveyor that now has a Tru-Trainer; including the reversing conveyors.
The Tru-Trainer series of Conveyor Belt Tracking idlers employs a patented, unique highly effective tracking action, which in non-damaging to the conveyor belt and reacts immediately if the belt begins to steer off center. Because it does not rely on contact with the belt edge in order to guide the belt, belt edge damage which frequently occurs with conventional tracking systems, is avoided.
This copper mill facility was processing crushed ore the consistency of sand. They were using conventional guide roller trackers that kept failing. Due to the design of the guide rollers they continually came in contact with the belt’s edge which made them slow to react and caused premature “side wear” on the belt. The operators were prone to “tying the guide rolls off” which eliminated “the ability for it to train/align the belt.” Also, “build-up” of carry-back on the external pivot caused freeze-up (stop working) making it vulnerable to the elements of the harsh environment.
Install ASGCO 36” Troughing Tru-Trainer® prior to where the problem of miss alignment occurred on the “load-carrying side of the belt.” Conventional training devises utilize “guide rolls” that cause premature belt wear and are slow to react to belt miss tracking. At no time does the ASGCO Troughing Tru-Trainer wing’s contact the belt’s edge.
ASGCO Tru-Trainer Troughing Idler’s unique center roller does all the belt’s steering. It’s quicker to react than conventional trainers with guide rolls. The internal sealed pivot was protected from the harsh elements and fugitive build-up in the copper mill, which caused the other conventional guide roller pivots to “freeze up” and not perform. ASGCO’s Tru-Trainer Troughing Idler’s superior belt tracking performance is saving them money due to less spillage, less downtime and less belt wear.
The driving force behind this project was initiated out of a safety issue. The existing bucket design would require 3 to 4 operators to manually flip the buckets, which would put the operators in a dangerous position, as the buckets are very heavy and could cause an injury during the process of flipping the bucket to change direction. Therefore, corrective actions resulting from an incident investigation were to redesign and re-engineer the bucket to enable the bucket wheel to change direction without flipping the buckets. Due to the split design of the new bucket, the challenge was to ensure the same tonnage would flow thru the bucket without any restriction.
The existing bucket wheel was modeled and a 3-DEM analysis was performed to establish a baseline of existing performance levels. We then incorporated the client’s models of the new split bucket design into the 3-DEM simulation and then compared the differences between the two designs and provided data to the client to show the results of the simulations. The client was able to view the results and make modifications to their design to improve the material flow and capacity.
After the new split buckets were installed on the bucket reclaimer, they were able to realize the time-savings of not having the maintenance downtime to flip the buckets, while maintaining the same capacity. They also found another benefit to the split bucket was that it evened out the distribution of the material on the belt, previously with the original bucket, when the material was transferred to the conveyor belt it would leave piles of material on the belt and, with the split bucket the material was more evenly distributed on the belt. Therefore, reducing the impact and wear on the belt.
This coal mine facility faced many challenges, as all bulk handling facilities do. Overcoming obstacles in improving the safety of their conveyor system was a top priority. These type of conveyor systems have tendency to mis-track causing the belt to cut into the hanging metal brackets holding the return roller in place. If and when the bracket gives way, the large return roller will be sent tumbling downward, creating a dangerous safety hazard.
After a thorough inspection of the conveyor it was pointed out that in addition to resolving the belt mis-tracking issue, there needed to be further changes made to ensure safety in the workplace and to comply with OSHA and MSHA requirements. It was recommended that they install ASGCO Safe-Guard Return Idler Cages to protect the return rollers and objects from falling, preventing injuries to workers and equipment.
ASGCO Safe-Guard Return Idler Cages were installed in the work areas and along the roadways to catch the return rollers if they fell. This brought the conveyors into compliance with MSHA title 30 regulations and helped the mine to reach its safety compliance goal! The customer was very pleased with the success.
The customer is a larger coal burning power plant that has had FGD Scrubber Conveyors in service for many years to help control the plants emissions. The product that is being conveyed is a synthetic gypsum product that is either conveyed or shipped to a nearby gypsum board plant. This product is very sticky and corrosive and builds up on the conventional return idlers and return trainers. This causes the belt to mis-track and rub the conveyor structure.
After ASGCO representatives surveyed the conveyor and pointed out some of the problems that were causing the belt mis-tracking, the benefits of installing two return Tru-Trainers to help keep the conveyor belt centered on the conveyor were discussed.
After installing the Tru-Trainers the belt immediately centered itself on the conveyor system. The customer watched the performance of the Tru-Trainer Flat Return Idlers and was extremely impressed.
In today’s manufacturing environments where the cost of downtime is measured in thousands of dollars per hour, polyurethane’s incredible durability actually increases your company’s profitability.
The diverse properties of castable polyurethane make it the leading choice of engineers looking for long lasting materials for their high load, high stress environments. Polyurethane routinely outperforms plastic, rubber and steel in its overall ability to resist harsh environmental factors such as abrasion, heat, solvents, oil and acid.
