“ASGCO® Solves Mid-Western Coal-Fired Power Plants’ Conveyor Transfer Point Problems”

Objective: To prevent chute pluggage and pre-mature wear while creating a flow within the chute and onto the belt.

Challenge: The existing round chutes were hard to align. The chutes had to penetrate two (2) different levels, each with existing openings and be able to line up so the material could flow without interference. The incredibly heavy, thick and pasty material made it nearly impossible to convey and to flow through the chutes, causing continuous outages and downtime for maintenance.

ASGCO® Engineering Uses Point Cloud Scanning to Custom Design Barrier Guarding For Two (2) New Systems.

Objective: To design and install barrier guarding on two (2) brand new wood chip conveyor systems. 

Challenge: This operator wanted to increase the safety of their new wood chip conveyors by installing ASGCO®’s Safe-Guard® modular flat guard panels.  Since these panels would need to be integrated onto a new conveyor, they wanted the application to appear as if it was an original component, without any compromise to the conveyor structure.  Additional precautions were needed due to the presence of combustible material in the environment.  The guarding would need to be installed without any drilling, cutting or welding that could produce combustible material, leading to a fire risk in a confined space.

ASGCO® Tru-Trainer® Eliminates Chronic Belt Damage at Northeast Aggregate Quarry

Objective: Solve belt mis-tracking and off center load issues

Challenge: An aggregate quarry had multiple issues that were keeping the conveyor belt off-track. They were experiencing severe off-center loading issues, along with belt tracking and alignment problems. The conveyor itself was ‘racked’ and not straight which meant it was not receiving it’s load uniformly. The mis-tracking was causing the belt edges to become frayed and worn, chewing up the sides of the belt. On several occasions, the belt became so severely mis-aligned, that it came in contact with the idler brackets and was sawing through them, leading to catastrophic damage to the belt, and causing extended downtime for the plant’s operations.

ASGCO®’s New Semi-Ceramic Pulley Lagging Solves Slippage Problems at This Canadian Cement Plant

Objective: To eliminate belt slippage problems while minimizing belt wear.

Challenge: This cement plant’s stacker conveyor was experiencing tremendous belt slippage problems that the conventional rubber lagging they were using failed to correct. The harsh wet and cold environmental conditions were tough on the belts and caused the rubber lagged pulleys to wear out quickly. The customer had been adamantly opposed to the use of ceramic pulley lagging, feeling it was too tough on the conveyor belts. A solution was needed that would correct the belt slippage and wear problems while addressing these concerns at the same time.

ASGCO®’s Primary and Secondary Belt Cleaning Systems Solve Multiple Issues at This Mid-West Redi-Mix Facility, While Paving the Way For an Additional Sister Plant.

Objective: Remove carry-back to eliminate housekeeping and clean-up requirements while improving employee safety to reduce injury risks and improve belt tracking issues.

Challenge: Installing the primary belt cleaner on the head pulley to remove the carry-back was relatively straightforward, with no major adjustments required. The installation of the secondary belt cleaner was a bit more challenging since it needed to be located further away than usual from the head pulley due to the conveyor’s snub pulley. The conveyor had a double truss system which would require us to install the unit in a “pass thru” style. A small chute extension was also needed on conveyor #2 to capture the removed material from the secondary to eliminate the clean-up requirements that existed on the #1 system due to the snub pulley.

ASGCO® Tail Box and Skirting System Solves Silica Plant’s Train Load-out’s Load Zone Material Spillage Challenge.

Objective: To minimize the carry-back and load zone spillage on both feeder belts coming from
the train unloader, to prevent contamination from one product to another.

Challenge: Material conveyed was constantly changing and needed to be controlled. The material from the train cars was not throttled at times, allowing for large surges. The solution needed to be versatile due to the constant changing of the material types and sizes. Due to these inconsistent flow rates plant employees were constantly cleaning out the pit spillage. The loss of product due to contamination and the cost of handing the material twice, to be reintroduced back into the material flow process, was increasing the cost per ton affecting a loss of profit. Material build-up behind the transfer that was escaping the existing skirting was wearing out the conveyor belt prematurely.

ASGCO® Engineering Design, Point Cloud Scanning Technology, Chute Fabrication, Syntron Feeders and Product Installation Provide Complete Turnkey Service at This Eastern Coal Fired Power Plant.

Objective: The older existing feeder was clogging and not producing enough product flow
to supply the operation. The objective was to restore and control the material flow from
an above ground surge to the underground conveyor belt that feeds the power plant.

Challenge: The conveyor descended down an incline into a narrow underground tunnel making movement difficult. The existing heavy feeders and knife gate needed to be removed but getting over the obstructions (such as existing equipment, detouring around piping and railings) was extremely challenging. In addition, five to six layers of stainless steel liners in the surge pile that feeds into the hopper had to be trimmed and cut in order to fit the new hopper against the ceiling. The need for accuracy in the design and prefabrication of the feeder system and chutes to fit the existing structures was extremely important to meet the plant’s capacity flow of 300 TPH of 2” minus coal.

ASGCO®’s Mini-Skalper® IV Solves Major Carry-back Issue At This North-Western Sand and Gravel Facility!

Objective: To solve major carry-back issues in a minimum of clearance space for clean up.

Challenge: This sand and gravel plant was experiencing massive build-ups of carry back.
The challenge was to be able to install a conveyor belt pre-cleaner that could eliminate the
carry-back and provide better cleaning efficiency in an extremely limited space. Manual
excavation everyday with continuous high pressure water on the ground was being used
to prevent the build up. This process caused increased labor and housekeeping problems
and became very costly to the customer. Also the water on the floor surrounding
the conveyor was contaminating the product.

ASGCO® Integrates Point Cloud Scanning Technology Into ASGCO® Conveyor Safety Product Installation at A Mid-West Coal Fired Power Plant.

Objective: Provide plant workers safety in the work place by the means of installing conveyor
safe guard equipment. Although the plant does not fall under either MSHA or OSHA
requirements, it strives for “best practice” that meets both regulations and ensures plant safety.

Challenge: Due to fire prevention in coal handling facilities, the plant required a turn-key installation that did not require a “burn permit”, thus all safe guarding panel railing and hardware had to be bolted onto existing conveyor structures and bolt hole patterns. The project required a very strict pre-installation measurement tolerance, that provided precise, accurate coordinates. This need for accuracy was extremely important in the prefabricating of the safe guarding fastening system onto the existing conveyor structures (such as existing holes, detouring around piping conduit and emergency stops). The plant had very limited down time and called for quick and efficient installation turnaround time.

ASGCO® Tru-Trainer® Dual Return Urethane Idlers Save the Day at this Copper Mine.

Objective: To track and align the conveyor belt on the return side of the belt before the loop
take-up section, while leaving the 6 series deflector pulley system with double speed reducers.

Challenge: The challenge involved an extreme incline conveyor belt 96” wide, with tandem
drives and a 6 pulley take-up system.  Due to the nature of this Drive system design, along
with the speed of the belt and together with the high tonnage that this system see’s during
each shift, severe belt mis-alignment was a serious problem. The conveyor belt had
tracking problems on the return side of the conveyor, especially through the 6 pulley
take-up system. This was exaggerated because of the incline and belt speed of this system.

ASGCO® One Sided Slide-ler™ Solves Load Zone Maintenance Problem at Coal Plant.

Objective: To provide load zone support, stability, and reliability in the transfer point
with limited access and to be able to service the impact rollers in the future quickly, easily,
and with minimal effort.

Challenge: The challenge was to be able to remove and to replace the impact rollers in
this tail section with access limited to only one-side, while  providing an easier alternative
to servicing them in the future. Many of the existing impact rollers had already failed.
Some were stuck, worn flat, shafts broken, and some were even missing. These impact rollers
were at a 10° trough, like many of the tailpiece style sections, where changing one of the
impact beds was very difficult.  The ‘off’ side of the transfer was blocked by a concrete
footing or pillar.  Any servicing that needed to be done on this side was cumbersome and
in some cases depending on the problem, impossible.

ASGCO® Dura-Sleeve® V-Return Idlers Solve Belt Tracking Problems at This High Tonnage South American Copper Mine.

Objective: Provide reliable rollers, better alternative to inadequate rollers that fail consistently.

Challenge: The demanding conditions of heavy tonnage and high speeds would wear out the
previous metal rollers too quickly. The high speed of 23 ft per second per second (7 meters)
and a tonnage capacity of 8000 tons per hour, caused the rollers to fail and fall apart, mainly
due to the rubber ring design. Specifically the problem was the high belt speeds that would
spin the rubber discs on the old rollers resulting in failure. Also the uneven wear was causing
the rollers to spin unevenly and then to overheat the rollers causing failures. The quality
required for this application needed to be extremely durable and wear resistant.

ASGCO®’s Retractable Razor-Back MDX® System with Spring-Shoc Solves Critical Carry-back Problem at Copper Mine

Objective: To prevent carry-back on a conveyor belt with long service hours, while decreasing
housekeeping and efficiency issues.

Challenge: This copper mining facility needed to remove the residual carry-back material from
the primary belt cleaner to run more efficiently and to reduce downtime. They were having to
clean once a week, taking took up to 3-1/2 hours each time, causing increased labor for housekeeping.


ASGCO® Eliminates Belt Tracking Issues with Low Profile Tru-Trainer®

Objective: Eliminate belt tracking issues that are resulting in major belt damage and spillage from contact with steel conveyor supports.

Challenge: For many years this conveyor had a hydraulic three return Idler belt training system that wouldn’t properly keep the conveyor belt in line.  The plant was facing constantly downtime to repair the hydraulic system.  Even when operational, the belt would veer off of center and come into contact with the structural supports, leading to critical damage to the belt and costly material spillage.  To further complicate this application, the conveyor also has less than 13” of height to mount any type of return training roller.  Options for eliminating the tracking problem were extremely limited by these space restrictions.

Composite Idlers Provide Advantages over Traditional Idlers

Objective: Need for long lasting, lightweight, and good resistance to abrasion and coefficient of friction.

Challenge: Most composite rolls are made from UHMW, Nylon or PVC. Overall lightweight rollers have the advantage, however not all of them are as strong (too much deflection on wider widths) or they don’t provide a good resistance to abrasion. The coefficient of friction is also poor, especially in wet conditions, which makes it more difficult to track or train the conveyor belt.

Dual Skalper® Primary Belt Cleaners Solve Major Carry-Back Problems at a Canadian Smelter Complex Nickle Mine

Objective: To remove the sticky carry-back and prevent it from falling off at various points causing major housekeeping problems.

Challenge: The conveyor belt adds the sand to the process for extracting the precious metals. All ore from any of their sites has to pass through this filter plant at some point. This sand belt has become a major problem due to the carry-back issues. The sand is very “STICKY” and therefore very hard to clean. Also there is limited space within the head chute preventing them from using a secondary cleaner. They were currently using a competitor’s pre-cleaner and also an Air Knife. These were not working and a lot of “Man Hours” were being spent shoveling the carry-back material back onto the belt.

New Conveyor Technology Improves Environmental, Safety and Productivity for Bulk Material

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.

This midwest coal fired power plant had this problem. The skirt rubber wasn’t getting adjusted or changed when needed; piles of coal all around the load zone area floor caused a safety hazard. The existing load zone was missing hoods, dust curtains and was rusting in some areas. All these problems together were causing coal to spill and coal dust to fill the air around the conveyor. More

ASGCO® – Troughing Tru-Trainer® Conveyor Belt Tracking System Solves Belt Tracking Problems at this Copper Mill Process Facility

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. More

ASGCO® 3-DEM™ Analysis of Existing Bucket Reclaimer and of a New Bidirectional Design Bucket to Verify the New Design Will Achieve the Same Output as the Existing Design

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. More
