Product Introduction
Man‑made sand make by crush rock. When finished sand pile and store, it will absorb water from air, have some free water inside. If moisture content too high, man‑made sand easy form arch and swell inside silo, make material hard to discharge. When do mix and batching later, material ratio will go wrong, direct bad effect for downstream building material product quality. Wet sand store long time also easy become hard and lump, not good for store and transport.
This three‑pass man‑made sand dryer develop for man‑made sand, which have sharp corner and strong wear ability. It change structure follow material feature, use three‑layer sleeve heat exchange structure to dry material. It can not break sand grain gradation, lower material water content, output stable dry man‑made sand. Fit for many sand plant real produce situation.
Feature and Detail Description
Man‑made sand grain have sharp edge, wear machine inner part very serious. At same time, downstream customer care much about finished sand grain gradation, they do not want too much stone powder produce when dry. This is main improve point for this three‑pass man‑made sand dryer.
Material flow inner drum, middle drum, outer drum one by one. Finish three step: absorb water evaporate, waste heat reuse, material cool down. Drum inside waste heat use again and again, reduce heat energy waste.
Drum liner, flight plate and all part touch man‑made sand use thick wear‑resist material. Against sharp sand grain keep rub and scour, slow part wear speed, make spare part use time longer.
Flight plate use big angle slow fall design. When drum turn, sand grain slide smooth and spread open. Reduce grain hit and rub each other. Hot air can go through material layer full, control stone powder produce number. Output sand dry and same, no local place become wet again.
Machine two end install compound seal part. Reduce hot air leak out from drum, stop fine stone powder fly out. Make workshop dust situation better, also less heat lose.
Whole machine have frequency convert adjust system. Can change drum rotate speed and hot air temperature follow feed sand moisture change. No need stop machine, still can adjust output sand water little bit.
Customer Worry Point
Many buyer afraid sharp man‑made sand will wear machine inner part very fast, later fix and change spare part cost very high.
We will choose different thick wear‑resist plate according to man‑made sand hard and grain sharp level. Also give suggest about how often check easy‑wear parts. Help customer prepare spare part early, avoid machine sudden stop.
Lots sand plant are old production line change, factory height and length space not enough. This three‑pass man‑made sand dryer whole structure compact. Same capacity, it take less place than single drum dryer. We can give machine place layout drawing according your factory real size, check whether site is ok.
Customer not have much money also care about long‑time fuel use. Three‑pass structure reuse waste heat well, keep produce can save many fuel cost.
Export customer pay attention to machine pack and transport protect. Before send out factory, machine do anti‑rust work. Export order use strong pack, fit for container load, lower machine damage risk from sea transport shake.
Some customer worry worker hard to learn operate machine. After debug finish, machine operate logic simple, daily use not hard. If work condition change, our technician can give parameter change suggest. Besides, drum coaxial adjust good, reduce machine shake when work, also make sand grain not easy break by hit.
After whole machine assemble finish, run no‑load test to check. Check seal problem, strange rotate noise and so on. All check pass, then do anti‑rust and paint work.
When send machine, we give full spare part list, write check and change time for each part. Customer can book visit our factory, see machine assemble by yourself. Custom machine will tell clear produce and delivery time, help customer arrange whole project plan.
FAQ
Q: What is the lowest moisture for three‑pass man‑made sand dryer output?
A: Normal work condition, output moisture can keep 0.5‑2%. Can change dry level follow downstream building material produce need.
Q: Will dry process grind man‑made sand sharp corner off, change original grain gradation?
A: Machine improve flight plate slant structure, make grain hit wear much less. But can not zero wear. If raw rock material soft, stone powder will increase a little. We can change drum rotate speed to make situation better.
Q: Feed man‑made sand moisture change big sometimes, can machine adapt this?
A: Small moisture change, can adjust hot air temperature and drum speed to solve. If feed moisture difference very big, we advice add buffer silo at front, make feed material stable, dry effect will more good.
Q: Already build sand production line, can add this three‑pass man‑made sand dryer?
A: Support old line change connect. Please give original feed hopper and silo size. We adjust dryer inlet and outlet height, try use old equipment, no need big factory rebuild.
Q: Which part need check and maintain often?
A: Flight plate and end seal part are important check place. Man‑made sand wear strong, need check wear situation often. Follow maintain manual to fix or change part, make machine can run stable long time.
