Reducing Urea Conveyor Spillage and Leaking

Any chance of posting some photographs, please?

Hi Nany,

Not familiar with the product Urea, is it a powder, liquid, large chunks or what? I work at a limestone quarry. We crush from 48" boulders down to 6" minus product. Our conveyors spillage is mostly moist "carry back" fines that fall off at the return idlers and the tail pulley. Wipers placed at the head pulley stop most of it when they are adjusted properly.

Hope this helps.

Since urea is a white powder, this is an excellent suggestion. Also, they could angle the wiper blade to deposit it into a bucket for possible reuse.

When ever it is possible our wipers are placed close to the head pulley so the "wipage" is dropped into the hopper below with the rest of the product.

There are all fashions of gadgets to use for wipers. Some are pre-tensioned, others are spring loaded, others use air shocks to maintain pressure. My favorite was fabbed by one of our repairmen. It uses a simple rubber wiper that has a counterweight for pressure. The weight is adjustable by sliding it forward or back to change the amount of pressure. This thing is so simple but very effective! It was made from scrap metal and took less than 4 hours to fab and install. Once in place you only have to replace the wiper when it wears out (about 15 minutes to change).

We have many air shock types also. They cost about $2500.00 each and are so complex and high maintainance they usually are not working properly.
