Product Brief
Quartz sand have high hardness and strong wear ability. Some washed quartz sand carry high water content. Direct use will bring bad influence for later sorting and purify process.
This three‑pass quartz sand dryer optimize special for quartz sand material feature. Use three‑layer sleeve structure recovery heat fully, continuous dry and dewater wet quartz sand. Output dry quartz sand with stable moisture, fit produce demand of quartz sand processing factory.
Product Application
Three‑pass quartz sand dryer mostly use for quartz sand after water wash and pre‑dewater, fit many different process scene.
Quartz sand ore‑dressing plant
Wet quartz sand from water‑wash sorting go to dewater sieve then enter three‑pass quartz sand dryer. After dry, go for sieve and purify work. Not affected by rainy weather, no need large area for sun dry.
Refractory raw material process
Dried quartz sand use as refractory raw material. Stable moisture make sure finished refractory product quality.
Man‑made board and glass raw material production
Supply qualified dry quartz sand for glass making and man‑made board process, avoid produce trouble cause by wet raw material.
Sand abrasive industry
Process quartz sand for sand‑blast rust remove. After dry, easy for store and pack, prevent sand become lump when get wet.
This machine also can work for other similar high‑hard grain material, but main optimize still aim at quartz sand heavy wear work condition.
Feature and Detail Description
Quartz sand is hard, it bring strong scour and wear to machine. This is main difference between three‑pass quartz sand dryer and ordinary river sand dryer.
Whole machine adopt three nested sleeve drum structure. Quartz sand flow inner drum, middle drum and outer drum one by one. Hot air cycle exchange heat, heat use rate is high. Compare with single‑drum dryer, save more fuel and take less site space.
Drum liner and flight plate which direct touch quartz sand all thicken, made of high wear‑resist plate. Resist long‑time scour and polish from hard quartz sand, lower spare‑part change frequency.
Inside drum use breaking‑up flight structure. When machine rotate, it throw quartz sand grain all the time, make every sand grain fully touch hot air flow. Reduce partial not‑dry and uneven dry situation.
Machine two end install labyrinth seal structure. Reduce hot air leak out, also stop fine quartz dust spill outside. Improve workshop work environment and cut heat waste.
Heat source support natural gas, coal, biomass pellet and other choice. Reserve dust remove port, can connect bag‑type dust collector, meet environmental‑protect discharge rule.
Production Strength & Quality Inspection
We own our process workshop. Core part of three‑pass quartz sand dryer such as drum and wear‑resist flight plate all cut and weld in our factory. Not depend on buy semi‑finished part for assemble, easy control product quality and delivery time.
Because quartz sand bring serious wear, factory inspection will focus check wear‑part weld firm degree, weld seam quality and seal assemble effect.
After each machine finish assemble, we check key size one by one. Only confirm no defect, then do paint and anti‑rust work, then arrange delivery.
For heavy‑wear material like quartz sand, we will give wear‑loss reference of easy‑wear part before delivery, help customer make spare‑part plan for later use. Normal model have stock. Custom model can offer clear delivery time. Welcome customer visit our factory to watch produce process.
FAQ Answer
Q: Does three‑pass quartz sand dryer have requirement for feed quartz sand grain size?
A: It fit grain‑shape quartz sand feed, fine powder content should not too high. If powder take big percentage, dust will become more during drying. We can adjust flight plate structure and match dust‑collect equipment to solve this problem.
Q: Will low temperature in winter influence drying result of three‑pass quartz sand dryer?
A: Low temperature will consume part heat, but machine itself can work normally. We can raise heat source power properly to make sure output quartz sand moisture up to standard. For north factory, we also can give insulation suggest according real factory condition.
Q: Is noise big when three‑pass quartz sand dryer run?
A: Drum rotate will produce basic machine noise, it is normal for rotary dryer. If site have strict noise control, we can select shock‑absorb part, also provide reference plan for noise reduce rebuild.
Q: Old factory with limited space, is three‑pass quartz sand dryer easy to place?
A: Three‑pass structure whole body is shorter than single‑drum dryer, occupy less area. You provide factory length, width, height and inlet‑outlet position, we can make layout plan for machine place.
Q: We never use dryer before, will you provide operation training?
A: Yes we will. We can explain operation key point and daily check focus by online video. When site install and debug, we also give practical training for local worker, teach simple fault judge.
Q: Can three‑pass quartz sand dryer work intermittently, run for a while then stop?
A: It support start‑stop interval, but do not suggest frequent switch on and off. Frequent start‑stop will consume more fuel, also speed up drum loss from thermal expansion and cold shrink. Better choose continuous produce in concentrated time period.
