Product Brief
Silica sand widely use in refractory material, chemical industry, casting and other field. After mine or stock pile, silica sand will absorb wet air from environment, carry certain water content. If water is too high, it will cause sieve screen block during grading, make defect in calcine process, also silica sand easy become lump when store.
This three‑pass silica sand dryer special fit silica sand feature: high hardness and grain fear over‑break. It use three‑layer sleeve heat exchange structure, finish dewater work gently. Control grain damage while process wet silica sand to qualified moisture, meet processing standard of many downstream industry.
Product Selling Point
Ordinary dry machine handle silica sand easy have problem: too much sand broken, dry not even, waste lots heat energy. Three‑pass silica sand dryer solve these pain point target.
Three nested drum structure, hot air reuse again and again, heat use rate is high. Compare with single‑drum dryer under same capacity, fuel consume lower, whole machine body shorter, take less factory space, reduce customer civil construction cost.
Adopt low‑speed heat dry idea, do not use strong hit to break material. Balance dry efficiency and silica sand grain complete degree, reduce fine powder output, guarantee finished silica sand grain size index.
Inner part do wear‑resist strengthen, stand high friction and scour from silica sand, lower wear‑part change frequency, reduce machine stop repair time.
Heat source choice is flexible, natural gas, biomass pellet, coal all can match. Reserve dust remove port, can connect dust collect device to catch silica sand dust, satisfy environmental‑protect produce.
Machine support 24‑hour long time continuous run, fit large volume regular produce demand of silica sand factory.
Feature and Detail Description
Silica sand have high hardness and strong grind ability. Many customer have strict require for finished grain size, do not hope generate too much fine powder. This is core optimize direction of three‑pass silica sand dryer.
Silica sand flow through inner drum, middle drum and outer drum one by one, finish heat dewater and slow‑cool discharge step by step. Hot air exchange layer by layer, heat loss is little.
Drum liner and flight plate which direct touch silica sand use thick wear‑resist plate, resist continuous scour and wear from silica sand, extend part service life.
Flight plate optimize radian. When throw material, main way is slide and spread out, reduce violent grain impact. Make hot air touch material full, as far as possible cut silica sand broken rate. Output sand dry even, no local still wet situation.
Two end install labyrinth seal structure, lock hot air inside drum, reduce heat run away. Also stop silica sand fine powder spill out, improve workshop work environment.
Equip frequency convert adjust module. According feed silica sand moisture change, can flexible adjust drum rotate speed and inlet air temperature, stable control discharge water content.
Customer Concern Point
When buy three‑pass silica sand dryer, many customer first worry silica sand break over‑limit during drying, cannot reach downstream grain standard.
We will adjust flight plate angle and drum running speed according customer silica sand hardness and grain size distribution, keep broken ratio in reasonable range. If raw material itself is brittle, we also will give real work condition reference to customer in advance.
Some customer do old factory rebuild, factory length, width and height is limited. Three‑pass model body is compact, take less space than same capacity single‑drum machine. Customer provide factory data, we can give machine layout suggest.
Many processing factory care about long‑time run cost. Three‑pass silica sand dryer have high heat efficiency, can save much fuel cost for long‑time production.
Foreign trade customer care about machine package and sea transport. Machine do anti‑rust spray before leave factory. Export order use strengthen pack, fit container load, lower damage risk from transport bump.
Later repair and maintain is also customer focus point. Machine reserve many maintain hole. Wear‑part such as flight plate and seal part easy to install and remove. We provide wear‑part change cycle reference, help customer stock spare part ahead.
Service We Provide
At pre‑sale stage, we can give machine selection plan according your silica sand real test moisture, target capacity and factory condition, also provide production line layout reference.
After machine finish produce, supply complete machine drawing, operation manual and maintain instruction. When machine arrive site, can provide online video guide for install and debug, teach worker machine operation, daily check and simple trouble shoot.
We supply spare part service for later period. Flight plate, seal part and other wear‑part can supply as need. If meet technical question during produce, our technician will reply at the same time.
