Product Brief
Frac sand mostly use as proppant for oil‑gas mining. The industry have strict require for finished sand moisture and grain complete degree. Wet frac sand after water wash have high water content. If dry not good, sand easy become lump when store, also bad for later sieve work and use effect at oil‑gas site.
This three‑pass frac sand dryer optimize for frac sand feature: high hardness and strong wear. It use three‑layer sleeve structure to recovery heat fully. Remove water while try best reduce sand break, output dry frac sand meet oil field material standard.
Product Selling Point
Ordinary dryer on market process frac sand often have many trouble: too much sand broken, output moisture change big, fuel consume high. Three‑pass frac sand dryer solve these problem target.
Three nested drum structure make heat reuse again. Under same output, fuel consumption is lower. Whole machine body is short, take less space than single‑drum dryer, reduce factory building cost.
Inner flight plate structure is improved. It stir material fully and lower grain hit and break possibility. Try keep frac sand grain round shape, reduce fine powder generate, meet quality demand of oil‑gas proppant.
It can work with many heat source such as natural gas, coal, biomass. Customer can choose according local fuel condition. Machine reserve dust remove port, dust from dry process can collect together, satisfy environmental‑protect produce rule.
Support long‑time 24‑hour keep run, fit large volume non‑stop produce of frac sand factory.
Product Application
Three‑pass frac sand dryer mainly handle wet washed frac sand grain, suit different produce scene.
Oil‑gas supporting sand plant
Washed wet frac sand feed into machine directly for dry. No need outdoor sun dry, will not affect by rainy weather. Dry sand go to sieve classification, get different mesh size oil field proppant sand.
Frac sand finished‑product process and storage
Lower material moisture inside industry standard, prevent sand lump during storage, convenient for bag pack and tank truck transport.
Sand tailing resource recycle
Qualified quartz tailing for frac sand production also can use this machine finish water‑remove work.
Feature and Detail Description
Frac sand own high hardness, it cause strong scour and wear to machine. Meanwhile we cannot break too much sand grain. This is key optimize point for three‑pass frac sand dryer.
Material flow through inner drum, middle drum and outer drum in turn, finish pre‑heat, water remove and cool‑down step by step. Hot‑air heat make full use, heat loss is small.
Drum shell and flight plate which direct touch frac sand all adopt thick wear‑resist plate. Resist long‑time sand scour, slow spare‑part wear speed, reduce machine stop for repair.
Flight plate structure is modified. When throw material, it reduce violent grain impact, cut frac sand broken rate, guarantee finished sand grain index.
Can match frequency convert control system. According feed material moisture change, adjust drum rotate speed and hot air temperature, stable control output sand moisture.
FAQ Answers
Q: For three‑pass frac sand dryer, how much moisture can output reach?
A: Under normal work condition, finished sand moisture can stable control below 0.5%. Also can fine adjust follow your produce index, satisfy oil‑field frac sand standard.
Q: Will lots frac sand grain break during dry process?
A: We improved flight plate structure, can reduce break situation, but cannot get zero break. If raw material grain is brittle, break ratio will rise a little. We can change machine rotate speed to get better result.
Q: Feed frac sand moisture fluctuate a lot, is machine easy to adjust?
A: Yes. Machine support frequency speed adjust and hot air temperature change. When raw material moisture unstable, worker change parameter can keep good output effect. If moisture change extremely big, advice add pre‑dewater sieve at front end to reduce main machine load.
Q: Can this machine make complete produce line together with sieve and dust collector?
A: Yes. We can match full set accessory including feeding, sieve, dust collector according your factory size and capacity demand, build whole frac sand dry production line.
Q: Low temperature in north winter, will it influence dry effect?
A: Low temperature will loss part heat, but machine still can produce normally. We can match heat source power according local lowest winter temperature, make sure output product quality up to standard.
