Abrasive Sand Dryer

Abrasive sand widely use in sand‑blast rust remove, surface polish, wear‑resist filler make and other area. Material store for long time, will absorb moisture from air, water stay inside sand grain. Wet abrasive sand easy stick together and form lump. It not only make material jam when discharge, block sieve screen, also change abrasive sand use performance. When store, sand easy become hard block, bad for sub‑pack and delivery goods.

This three‑pass abrasive sand dryer special develop for abrasive sand, it have high hard and strong grind feature. Use three‑layer sleeve heat exchange way to take away water. Keep sand grain original shape as much as possible while keep dry efficiency. Output finished abrasive sand with stable moisture. Suit real produce condition for all kinds abrasive process factory.

Old dry machine process high hard abrasive sand always have many problem: inner part wear fast, finished sand dry not same, waste lots heat energy. This three‑pass abrasive sand dryer solve these trouble target.

Three nested drum make waste heat cycle use, heat exchange efficiency become much higher. Compare old single‑drum dryer with same process capacity, fuel consume can control well. Machine body length more short, need less factory space, help factory spend less money on factory rebuild.

Inside use slow throw material handle idea, do not use strong hit to break sand. Make hot air touch sand enough, at same time control fine powder produce amount, keep finished abrasive sand grain size standard.

All spare part touch sand do wear‑resist strengthen handle. Resist abrasive sand keep grind and wash, make spare part change time longer, reduce produce lose from unexpected machine stop.

Support many heat source: natural gas, biomass, coal all can use. Machine leave dust connect port, can match dust collect system catch abrasive dust, meet workshop environment protect rule.

Machine can run long time without stop, fit large volume and continuous produce for abrasive sand factory.

Abrasive sand is very hard, grind force is big. Downstream produce need sand grain keep complete, this is main design idea of three‑pass abrasive sand dryer.

Abrasive sand flow through inner drum, middle drum and outer drum one by one. Finish heat‑up remove wet, waste‑heat recycle and material cool down step by step. Hot air inside drum reuse again, reduce useless heat lose.

Drum liner, flight plate and other part touch material use thick wear‑resist plate. Stand sand grain keep rub and scratch, make spare part use time more long.

Flight plate have special curve shape. When drum rotate, sand slide and spread out. Reduce hit between sand grain and steel plate. Make hot air touch every sand grain full, also lower grain break chance. Output sand dry same, no local still wet problem.

Machine two end install labyrinth block flow seal part. Lock high‑temp hot air inside drum, less heat run away. Also stop fine abrasive dust fly outside, make workshop work environment better.

Have frequency convert adjust module. When feed abrasive sand moisture change, can flexible change drum rotate speed and inlet air temperature, keep output sand moisture stable.

Many buyer first worry is abrasive sand very hard, will make machine inner part wear fast, later repair and change spare part cost very high.

We according customer abrasive sand real hard and grain size situation, match suitable wear‑resist plate. Also give check cycle suggest for spare part. Help customer stock spare part early, avoid machine sudden stop risk.

Some customer do old workshop upgrade, site space not enough. Three‑pass abrasive sand dryer body compact, take less space than same capacity single‑drum machine. Customer give factory length, width and height data, we can give machine place layout for reference.

Process factory care much about long‑time run cost. Three‑pass structure waste‑heat recycle good, can save lots fuel cost when produce long time.

Foreign trade customer pay high attention on machine pack and ocean transport. Machine do anti‑rust spray before leave factory. Export order use strong pack, fit container load, reduce machine damage from sea transport shake.

Some customer worry machine hard to learn operate. Whole machine electric control logic simple, after debug, operate not hard. If work condition change, our technician give parameter adjust suggest, help customer get stable produce fast.
