Detailed Product Description

brick making machine

Zhengyi introduces advanced technology abroad into manufacturing of aerocrete-making equipments.These equipments can turn out aerocrete blocks no more than 6 meters.According to their fifferent cutting technologies,they can be devided into two kind: Hydraulic turning-over cutting machine and airborneturning-over cutting machine.

Supply sand aerocrete block equipments suits applicable to the annual production of 20 thousand CBM to 400 thousand CBM;

Supply equipement suits that can be used for both aerocrete block and sand lime brick.

I.The development and features of aerocrete:

Aerocrete products have gone through nealy one hundred of years and have been the supportive industry of construction industry.In our country aerocrete technique have been developed for about 40 years,and its technique skills and equipements are going mature.The aerocrete has the features of light bulk density,good thermal insulation properties and sound-absorption, certain strength and process ability,and its raw materials is very rich,especially the reuse of flyash enables the comprehensive utilization of industrial residue,curb environmental pollution,no destroy on farmland,creat good social and economic benefits.Acrocrete is a ideal alternative of the traditional clay brick wall materials.For many years acrocrete has been strongly supported by national wall reform pocily,tax policy and environmental policy.In a sentence,acrocrete has been an important factor in new building materials and has a broad market prospect.

II.Aerocrete processing technics:

1.Storing and supplying of  raw meterials of aerocrete blocks.

All raw meterials are carried into factory by trucks.Fly asn,sand or lime are gathered in specified raw materials field waiting for use.Sacks of cement and bulk cements stored in cement warehourse.Chemicals and aluminium porder are seperatedly keeped in chemical warehourse and aluminium ware hourse.When used,these raw materials are carried into workshop respectively.

2.Processing of raw materials:

Flyash,sand or limestone  is sent into ball mills by vibration feeders and belt conveyer.Then fine powders of flyash,sand or lime are pumped into slurry tank.

Quick lime is sent by vibrating feeder and belt conveyer into jaw crushers to smash. Smashed lime is sent into lime silo by bucket elevator and then is transported into ball mills by screw conveyer. Fined materials are sent into proportion bin by screw conveyer and bucket elevator.

Aluminium powder is lifted by a truss motor to second layer of batch planta and empty into mixer.Then quota water is poured to make aluminium powder into suspension.

3.Aerated block ingredients,stiring and casting

Flyash (or sand or stone powder )and waste slurrry are measured in mesuring tank.After the measuring and mould in their place,slurry stirring begins.Slurry temperature should reach about 40°-This is technical requiremnents.If the actual tepreture doesnt arrive 40°,vapor is used in the measuring tank to raise temperature.Half or one minutes before casying,aluminium suspension is supposed to be added to the slurry.

4,Aerated blocks precuring and cutting.

Cat model is conveyed to precuring room for gas forming. Room tempreture should range from 50°to 70°.This period lasts one hour and a half totwo hours.(If materials take on geographical advantages,this precuring can be eliminated.Precured green body together with frame  will be lifted to cutting station that is covered by autoclave board.After frame detachment,cutting machine conducts cross-cutting,scoring-cuttint,face-milling and tip-binding. At the same time, die grid is hanged to precuring cart for manual cleaning and degresing to prepare for the next perfusion. The cutting ready embryois are carried to precuring cart together with die seat, palletizing in two tiers, four pillars between two the tiers, and get into grouping process.

When the cutting of body is completed, partial waste materials cut down will be processed into waste material slurry which then will be pumped to the slurry tank located at the topmost story of batching building, after that, add the necessary raw material, then transported into a  pulping machine for reuse.

5, Autoclave and finished products

After the greenbody is grouped,open autoclave door,a hoist will draw out autoclave cart;Put all green body on the cart and wind the cart back into the autoclave for steaming.Finished products will be carried by a bridge crane to a stockyard,then to a  products dump by fork lorry loade.The empty card together with autoclave bottom is lifted to return-line cart and winched back for another circle.
