Q&A

Q1: What is the difference between a trommel and a shaker table used for gold mining?

A1: A shaker table is another common gold recovery machine, but it works differently from the trommel. While the used gold trommel for sale separates materials based on size, the shaker table used for gold separation depends on the weight. The shaker table is usually used as a secondary recovery machine after the gold trommel has done the bulk of the work. The shaker table stops lighter materials from passing through and only captures the heavier ones, which include almost all gold nuggets.

Q2: How does a gold trommel work?

A2: The used gold trommel for sale works by separating materials according to their size. Large boulders and rocks exit the trommel without further processing. Smaller materials then pass through the screen at the base of the drum. Before doing so, smaller materials get caught up in the rotating drum, where they come into contact with water and ore reagents. Consequently, the desired materials settle down and are later collected in the sump.

Q3: What are the advantages of used gold trommels for sale?

A3: Gold trommel machines are widely used in the mining industry because they offer an incredibly efficient means of separating and processing materials. Gold trommel machines can also work with different material types and qualities. They are sturdy and robust machines that provide operations and miners with years of consistent use.

Q4: Where do most used gold trommels for sale go?

A4: The main gold trommel machine market consists of countries that have a significant gold mining industry. Most of the machines are sold to the United States, Canada, Australia, China, and Chile. These countries have large-scale commercial mining operations and, therefore, greater demand for gold trommel machines.
