1. Introduction:

River sand dryers are also called sand dryer, river sand dryer, sand drying machine, yellow sand dryers, dry mortar dryers, etc. River sand( yellow sand, mechanical sand) is an important raw material in construction engineering, with the requirement of urban development and construction, cement mortar (dry powder mortar, the mixed mortar, dry mortar, insulation mortar) and the demand is also increasing, the kinds of river sand dryer arises at the historic moment, and is widely used in sand making, building material, metallurgy, mineral processing, chemical industry, cement industry, etc.

3. Features of river sand dryers:

1), the river sand dryer requires less investment, my company river sand dryer is the most preferential price 20% of imported products, highest performance-to-price ratio.

2), the river sand dryer we produce has high wear-resisting degree, the wear resistant manganese plate making, than ordinary steel wear-resisting 3-4 times.

3), the thermal efficiency of more than 40% higher than that of traditional single drum dryer.

4), fuel can be used white coal and bituminous coal, coal gangue, oil, steam. Can bake 20-40 mm the following piece of material, aggregate, powder material.

5), covers an area of about 60% lower than single drum dryer. Civil engineering investment to reduce 60%, installation is convenient.

6), no air leakage phenomenon, solved the sealing difficulties.

7), discharge temperature of 60 degrees or less, can be directly feed library, need not into cooling tent cooling.

8), outer barrel temperature 60 degrees or less, exhaust temperature

9) is the 1/3 of single drum dryer, coal consumption, energy saving 40%, tons of standard coal consumption

10), material initial moisture 15%, final moisture to ensure below 0.5 1%, is the cement slag powder, dry mortar production line and other various drying engineering preferred products.

11), its resistance to overload ability is strong, large quantity, less fuel consumption, dry low cost;

Various Flight Designs for Rotary Dryers when Drying different types of materials(Example: a is suitable for sticky material)

Different Types for Flight Designs for Rotary Dryer	Cascade Motion of Materials in Rotary Dryer

To ensure that the dryer is loaded close to optimal, it is important to know the amount of solids that can be held up in the flights. If they are underfilled, the dryer will be performing inefficiently, below its capacity. Excessive overload of the shell will result in a

proportion of the material transported by kiln action,and the contact with the hot gases is limited. The residence time of the solids will be reduced and the quality of the product may be unacceptable.

4. Working principle of river sand dryers

River sand is conveyed by belt conveyor or bucket elevator to the hopper, and then the hopper feeder through feeding chute into the feed end of dryer. The feed chute slope should be greater than the natural inclination of materials, so that the material flow into the dryer smoothly. Dryer cylinder is a flat line with water slightly tilted into the rotation of the cylinder, materials from high end to join, heating medium from low-end to enter, and material into a counter-current contact, there is also a heating medium with materials and flow into the cylinder. With the rotation of the cylinder material by gravity Run to the bottom on the lower side, wet material in the process of cylinder body move forward, directly or indirectly get the heating medium for heat, to dry the wet material, and then by the belt conveyor or screw conveyor at the discharge end.
Inside the cylinder wall is equipped with lifters, whose role is to put the material lifted up and again, the contact surface is increased and the air flow of material, in order to improve the drying rate and promote the material into, before heating medium is generally divided into hot air and flue gas, heating medium by the dryer, generally need to cyclone with materials in the gas trap, for further reduce exhaust dust content, should also be after bag filter or wet precipitator put emissions.

Our drying equipment factory was established in 1950s with technology assistance from Russian experts. Since then the factory has never stopped pursuit of upgrade of our drying equipment, many specially designed dryers for challenging materials had been developed during even 1960s-1970s without any outside help. The spirit of constant pursuit on technology upgrade and commitment to quality and process optimization had passed on from generations to generations.

Today, with an open mind and eagerness to better serve customers, we had learned from western counterparts, integrated European technology into our products selectively according to our current industrial circumstances in China based on our past experiences, which makes our products more effective, competitive and much easier for customers to accept. We are proud of products that had provided numerous businessmen new opportunities and even more workers jobs, all of which had been indispensable in our social welfare improvement and industrial development.

Time had witnessed our growth and we shall never cease to change times with our products.

To all ambitious and hardworking entrepreneurs all over the world, we offer our products to change your tomorrow for the better and better. Please give us a call for your requests. We are at your disposal at any time.

Our China Turnkey Service Roller Dryer Three Cylinder Dryer Rotary Drum River Sand Dryer! adopts two vibrating motors rather than the normal motor plus vibration exciter structure as the vibrating device. Vibrating Screen Feedere becomes simpler, smaller, and lighter. The work noise is also very lower. The reliable and energy-saving motors can feed material stably. China Turnkey Service Roller Dryer Three Cylinder Dryer Rotary Drum River Sand Dryer! has much bigger conveying capacity and is easy to be installed and maintained.

In our vibrating feeder, Vibrating Screen Feeder are rotating synchronically and oppositely. Thus the vibration absorber supported feeder can move linearly, China Turnkey Service Roller Dryer Three Cylinder Dryer Rotary Drum River Sand Dryer! and the material can move forward and get loose immediately once fall into the trough.

Vibrating Screen Feeder is designed for the sieving of solid-liquid materials. Vibrating Screen Feeder vertical motor, which is installed eccentric hammers on the top and bottom, is regarded as a vibratory source. The eccentric hammers change rotation into horizontal, vertical and inclined movement, and then pass the movement to the sieving surface. Adjusting the phase angle on the top and China Turnkey Service Roller Dryer Three Cylinder Dryer Rotary Drum River Sand Dryer! can change trajectories of the materials on the sieve.
