Product Brief
Sea sand get from seaside, it not only have lots water, but also contain salt inside sand. Ordinary dryer easy be corroded and damage by salt after long time use.
This three‑pass sea sand dryer optimize special for sea sand material. Use three‑layer sleeve structure make full use heat, evaporate water from wet sea sand. Treated sea sand can meet downstream produce use requirement.
Product Application
Three‑pass sea sand dryer mainly deal with wet sea sand after desalinate wash, fit many real produce scene.
Coastal sand plant
Sea sand mined and washed from seaside feed into three‑pass sea sand dryer directly for dry. Not limited by rainy day sun dry, output dry sea sand finished product directly.
Building material raw material process
Dried sea sand use as raw material for dry‑mix mortar and road base filler, keep raw material moisture stable.
Casting industry
Qualified dried sea sand serve as casting molding sand raw material, reduce casting air hole defect.
Complete production line match
Can cooperate with feeding, sieve and dust remove equipment, build full dry flow line. Finish sea sand feeding‑dry‑discharge whole process in one‑stop.
Feature and Detail Description
Sea sand carry salt and have corrosive property, this is the biggest difference between three‑pass sea sand dryer and ordinary sand dryer.
Machine adopt three nested sleeve drum structure. Sea sand pass inner drum, middle drum and outer drum one by one to finish dry work. Hot air heat reuse again. Compare with single‑drum dryer, fuel consume lower and machine take less space.
All drum and flight plate part direct touch sea sand do anti‑corrosion and wear‑resist strengthen handle. Resist corrosion bring by salt inside sea sand, reduce risk of spare part corrode and hole appear, extend whole machine service life.
Special structure flight plate inside drum. When rotate, it lift and spread sea sand constantly, make every sand grain can touch hot air. Avoid local not dry completely and dry uneven problem.
Two end equip labyrinth seal structure, reduce hot air run away, also stop dust spill out. Workshop have less flying dust, heat loss reduce, save more fuel.
Heat source choice is flexible, natural gas, coal, biomass pellet all can match. Machine reserve dust remove port, can connect bag‑type dust collector, meet environmental‑protect discharge standard.
Function Introduction
The core function of three‑pass sea sand dryer is continuous dewater and dry for high‑moisture wet sea sand.
Wet sea sand after wash send into feed inlet by feeding device. Drum keep rotate, sea sand move forward slowly inside three‑layer drum, fully exchange heat with hot air, water inside sand keep evaporate.
Can adjust feed speed, drum rotate speed and hot air temperature, flexible control sea sand final moisture after dry, fit different customer produce standard.
Whole machine support long‑time non‑stop continuous produce, satisfy large‑volume sea sand process demand of sand yard.
Match electric control cabinet, operation is simple. Worker can operate after short train, can check machine running status directly.
FAQ Answers
Q: What moisture content can three‑pass sea sand dryer dry sea sand to?
A: Under normal work condition, sea sand can be dried to 0.5%‑2%. Parameter can adjust follow your produce target.
Q: Sea sand have high salt, will it corrode and break machine?
A: The spare part touch sea sand have anti‑corrosion and wear‑resist handle, can lower corrosion loss. We more advice do wash desalinate at front first, remove most salt before send into three‑pass sea sand dryer, machine service life will be longer.
Q: Feed sea sand moisture is extremely high, can machine handle it?
A: Too high moisture will increase dry load, we can adjust heat source configuration. If moisture is abnormal high, advice add pre‑dewater process at front, guarantee dry effect.
Q: Is later‑period maintenance of three‑pass sea sand dryer very trouble?
A: Main maintain wear‑part such as flight plate and seal part. Under salt environment, spare part wear a little higher than ordinary river sand work condition. We will provide maintain manual and mark replace cycle, daily maintain difficulty is not high.
