Belt Press Maintenance after winter

20150928_082313_resizedIt has been our experience with our mobile belt presses and assisting clients with their equipment that no matter how diligent your winterizing maintenance schedule for a machine located in the colder parts of the country are, something usually needs some attention come the spring thaw.

The freeze thaw cycle of water through the winter months can be tough on a belt press. We drain and blow down with air all the plumbing on a piece of equipment multiple times in order to try and prevent pipes breaking but there always seems to be a cracked 90 or two.  The best way to find these potential leak causing cracks and breaks is to water test your machine prior to putting it back in service.  This usually will identify any major issues.  Outside of that, pay close attention to all your lines the first few weeks of operation and be sure to have your parts inventory current for when a fix is needed.  If it gets to the point were the spring repairs are hurting production, give us a call we would be happy to help and/or send one of our mobile belt presses to help keep you going while the repairs are made!

Mechanical vs. Hydraulic Dredgers

1In general, dredges (also known as dredgers) come in two basic forms: mechanical and hydraulic. Mechanical dredges work by mechanically digging or gathering sediment from the bottom surface of a body of water, typically through use of a bucket.  Mechanical dredging takes place at the shoreline or working off of a barge and may or may not involve draining a lake.

The most common mechanical dredger is the bucket dredger, which is stationary, fixed by anchoring and moves while it dredges by winches. It features a number of buckets that fill as it scrapes the bottom. The material that is dredged is loaded in a barge and hauled away. This type of dredge rental is the most common in many industries.

Hydraulic dredges, on the other hand, work by sucking up a mixture of sediment and water (known as slurry) from the bottom surface and then transferring the mixture through a pipeline to another location. This dredge acts like a giant floating vacuum, removing sediment.

Dredges are used to move, and remove, a wide variety of materials, such as waste, gravel, trash and sediment.  Dredges help to keep canals, ports, harbors, and marinas clean. Dredges even help to restore beaches and land lost due to erosion.

Hydraulic dredging is most effective when working with finely grained material. Coarser things, such as gravel, can be handled but will put a higher demand on the pump, causing it to wear more quickly.

Are you looking to remove silt, sand, mud, and other sludge materials that has decreased your ponds capacity? Contact Sandling Industrial Services for mini dredge rental, which will help you to restore full capacity to your water source.

Dewatering 101

1.7 Meter Belt PressIf you’re in the business, you already know plenty about dewatering. But , if you’re new to the industry, or you’ve simply heard the term and are wondering exactly what it is and how it’s accomplished, allow us to give you a  brief overview.

First, to put it simply, dewatering is the removal of water. This process is used in many industries but commonly referred to in construction and wastewater when water is separated from solids through a variety of different pumping or filtering processes.

Construction dewatering involves pumping from wells or sumps to temporarily lower groundwater levels, to allow excavations to be made in dry and stable conditions below natural groundwater level. In wastewater treatment, dewatering is the part of the process where sludge is reduced in volume and converted from a liquid to a solid.

If you’re in need of mechanical dewatering equipment, trust the professionals at Sandling Industrial Services. Our mechanical dewatering systems are optimized to help you remove all types of solids from your waste water. Our belt filter and chamber filter presses utilize sophisticated methods that separate your solid and liquid phases. We have the knowledge and skills to help you get the job done. We service the entire United States, so call us today for help with your dewatering project.
