Customer Alamo Cement, San Antonio, TX, USA


Alamo Cement, located in San Antonio, was experiencing issues with tacky, clay-heavy raw material from the quarry. The cargo would stick to the return side of two of its stacker conveyor belts, resulting in excessive carryback and accumulation along the belt path. Operators found, even with regular tensioner adjustments, the cleaner blades would not maintain adequate contact with the belt, rendering them ineffective. Due to accumulating carryback, properly positioning the stacker conveyors was a challenge, so each morning 4 employees would have to spend at least 2 hours using shovels and machinery to dig out the portable systems and level them. Operators estimate the issue cost more than $200 per day and took valuable manpower from other priorities.

Without adequate cleaning, tacky material clings to the belt along the return run.n


Martin Engineering® Mr. Blade® technicians were invited to examine the issue and provide a solution. They immediately identified problems with how the competitor's existing cleaners had been mounted on the stringer, the use of inadequate blades, and issues with the tensioner. Martin® QC1+™ HD Cleaners were installed to dislodge the caked-on material. Given the space restrictions, technicians chose to install spring tensioners. To offer more consistent tensioning and better blade performance, installers fabricated a mounting plate for the stringer. The Mr. Blade Program safely services and maintains the blades using trained experts driving specially equipped vehicles.

A plate mount improves cleaner stability and helps tensioners maintain adequate blade-to-belt contact.


Following the installation, operators tested the cleaner and tensioning system. It offered immediate results on both conveyors, cleaning the belt with little to no carryback. After some time in operation, managers close to the project reported that the morning cleanup ritual had been discontinued and only periodic scheduled cleaning is needed. "The added benefit is to morale," said an operator. "We can focus on more pressing matters than digging out the conveyor." The personalized service and fast return on investment has prompted the plant manager to put together a budget for retrofitting the rest of the conveyors with similar solutions throughout the site.

The Martin QC1+™ Cleaner HD removes high volumes of punishing material.

Heavy-Duty Belt Cleaners Provide Dramatic Carryback Reduction on 12 Conveyors
A frac sand producer in Texas was having issues with carryback around the discharge zones of 12 conveyors unloading into 120 ft (36.5 m) tall storage silos. Due to the naturally adherent characteristics of silica and the fine particle size, the sand was sticking to the surface and getting into cracks in the belt, dropping off along the return side. With only stairs to access the tops of the silos, each shift designated a worker with an air wand to spend their entire shift blowing sand off the top of the silos.
