Mineral Processing Plant Triple Pass Rotary Sand Dryer

Triple Pass Rotary Sand Dryer Features

The triple pass rotary drum sand dryer is an improved machine based on the single rotary drum sand dryer.

After continuous testing in actual cases, the current triple pass rotary drum dryer machine was manufactured.

Its internal structure is three layers, so it is called three pass rotary drum dryer.

It increases the drying time of wet raw materials. In terms of tightness and thermal insulation, the triple pass rotary drum sand dryer is more reasonable than the single pass rotary drum sand dryer. In terms of production capacity, the triple pass rotary drum sand dryer is more than 60% higher than the single cylinder dryer

The sand drying machine widely used, including slag, clay, coal, iron powder, ore powder and other mixed materials in various industries, dry mix mortar plant in the construction industry, silica sand and other raw materials in chemical industry and casting industry.

Triple Pass Rotary Drum Dryer Technical Details

Structure of Triple Pass Rotary Drum Dryer

This triple pass rotary drum sand dryer machine is designed by three concentric cylinders with different diameters according to a certain mathematical relationship.

The rotary sand dryer fuel can be gasoline, coal, gas, etc. You can choose different fuels according to your needs. It is a set of energy-saving and environmentally friendly green sand drying machine.

It is designed with material guide plates at different angles, which can make the material move along the material guide plate under the action of gravity, then the wet raw material has enough residence time to quickly evaporate water, saving fuel and time. It is your ideal sand dryer.

The length of a triple pass rotary dry machine is one-third of the length of single rotary dryer machine.

Each drum has formed its own insulation system, the heat exchange of the materials in the drum, the outermost material is at the low temperature end of the hot airflow, the heat dissipation area and heat energy loss of the cylinder are significantly reduced .

The energy-saving three cylinder rotary drum dryer can make full use of waste heat, reduce heat loss, increase the heat exchange area, and greatly increase the evaporation intensity per unit volume of the dryer, thereby effectively improving the heat energy utilization rate, reducing energy consumption.

The length of rotary drum sand drying machine body is one-third of single rotary drum sand dryer, save the floor area, reduced the investment cost.

The rotary sand dryer machine adopts a friction drive between the supporting wheel and the belt, and the transmission power is low, which reduces the noise when sand drying machine is working.

The sealing system adopts micro-contact technology, which has better sealing effect and reduces dust pollution.
