sand and gravel wash plant

Trommel Screen merges high output screening and high output grading into a mobile trommel solution which in turn offers extra mobility to bring the screen to the product, enabling material to be screened on site keeping transport costs and processing costs low.

Descriptions( 100tph Mobile Alluvial Gold Washing Trommel Screen )

Material feeds into the drum, is lifted up by the rotation as it falls back down. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum.

The trommel screens provide a simple, efficient and economical solution to upgrade a wide rang of material and optimize the subsequent process steps of recovery. This method of screening helps to reduce operating and investment cost and to increase product quality, while allowing rapid and large volume processing. This material is then passed on to the downstream process equipment which can be in various forms such as centrifugal concentrator, spirals, jigs etc.

Mobile Diesel Rotary Drum Trommel Screen With Staff Operation Platform

Main Technical Parameters

Q: Is your original ore sticky clay? Or only alluvial/placer sand?

1) If contain sticky clay ore, more than 30% or not?
2) Capacity?

2) -3mm materials percentage?

Q: Biggest capacity our trommel screen can process?

A: 200-300tph

Q: How big are the screen mesh size and how many layers?

A: Usually, our trommel is double layer, the inner screen mesh is 5mm, outer screen mesh is 10mm. But we can build it as you require, we will use the Ø25mm diameter round steel to build the inner screen mesh if the inner screen mesh size reaches 30-40mm.

If you want three layers, or different screen mesh size in different section, we can build it too.

Q: If very small outer screen mesh size, will clogged?

A: We will add a steel brush onto the drum, so won’t be clogged at all. And we use the unique screen mesh design, result in sand and gravel wash plant screen life & no material clogging.

Q: Screen mesh material?

A: We use high manganese steel to build the screen mesh which is very durable.

Q: Can we change the screen mesh?

A: Yes, you can, usually we build the screen mesh to be active, so you can change the screen mesh size by yourself easliy on site.

Q: Driving mode?

A: Usually it’s electric motor, if you want, we can build it to be diesel engine for driving. Or build it to be diesel generator to provide power for it.

Q: If i need the complete mineral processing line. Can you help us build it?

A: Yes, we can help you combine a complete mineral processing line. and give you related professional advice as long as you need.
There is a rich experienced engineers team of us, these 12 engineers always fly out of China to install, debugging our equipments on site and trainning the buyer’s staff.

Usually for alluvial ore, the flowchart is: Hopper---Trommel Screen---Vibrating Sluice/Jig/Gold Centrifugal Concentrator---Fixed Gold Sluice---Shaking Table For some other minerals, we can add magnetic separator, electric separator etc

Q: How long is the guarantee of your equipments? Does your company supply the spare parts?

A: The warranty period of is one year, if break during this guarantee period, we need to replace new one for you AT NO COST. And of course we will supply the spare parts for you for life-long time at lowest cost.

Q: Do you cut the steel plate by hand?

A: No, we use the plasma cutting machine to cut all materials which is controlled by computer. It’s very accurate, only we have this machine, other factories use manual cut.
