Raw materials after screening and crushing, through pressure and vibration, become one-time and final molding

QTY4-15 brick making machine:

This machine is of multi-function

For this machine, both the table vibration and pressing head vibration are adopted. So, the blocks manufactured by this machine are uniform in density and high in strength, its unique quantitative feeding device and powerful materials distributing device can ensure the qualities of the blocks of all kinds of raw materials. With PLC control system and high productivity, this machine is one kind of ideal equipment for producing new-type of wall materials.

Only by changing its moulds and dies, the perforated bricks, standard bricks and hollow blocks of different specifications can be produced. Additionally, by using the secondary material distributing device, many kinds of color-faced pavement tiles, color-faced grass-planting bricks and curb bricks can be produced, too.

For this machine, the multiple directional control valve system is adopted. So, it is reliable in working operation.

By equipped with unique forced material feeding device, and special material-arch releasing rod, which is suitable for different mould cavities for forced arch-releasing and secondary mixing, the machine can, at its maximum extent, ensure the uniformity in material distributing while using large quantity of fly ash.

 

Unique features as follows:

 

1. changealbe moulds: we can provide 3-4 sets of different kinds of moulds for your choice. Meanwile we could provide 1 mould and 25 pallets for free.

 

2. best sale service: we could sent one professional man to your place for installation, as for the spare parts, we could provide you together with the host machine as well.

 

3. whole production line: we could provide the brick/block making whole production line for you, it need all together 7-9 people, one is for loading the material, one is for the mixer, one for the PLD system, 2 for the forklift, sending the finished bricks to the maintenance zone, 2-4 for the moving of the dry bricks

4. our brick/block machines are all after specialized testing before finished.

5. working manners are both hydrualic pressure and vibration.

6. PLD control system is controled by screen operation.

7: the proportions are stone(0-5mm): sand: concrete=5:4:1, the weight hopper can hold 1ton materials at most.

 

production processing chart:

 

 

Automatic block making plant 

consists of batching system, mixing system, pressing system, control system, conveying system and handling system and during system.

A: semi-automatic plant: consists of automatic batching mixing and pressing system, manual transfering and stacking system with natural curing(or elevator/lowerator/stacker)

B: full automatic plant: consists of automatic batching mixing pressing conveying finger car transmitting, manual stacking and curing system.

According to the actual situation of each user specific analysis targeted personalized design tailored specifically for customers to provide the most suitable equipment closed fully automated production lines of the whole superior funcions

Products: hollow blocks, curbstone grass block, slope block, interlock block and so on.

Widely used for construction roads plazas water conservandy project such as building materials garden material by coal ash, slag, coal pole stone, pearlite, pottery grain, industrial waste material  and so on 

Manufacturing detail progress:

1.Raw materials are delivered to the production site by trucks, railroads or barges. The raw material should be properly stored, mostly in open stockpiles, however, to ensure not affected by raining, the cover area should be considered for 1 week supply.

2.The cement can be handled in bag or bulk package. Bagged cement: workers put the bagged cement in mixer hoist by cutting the cement bags and the quantity of the cement will be counted manually. Bulk cement: cement is transported by bulk tankers and pumped into the cement silo for temporary storage. The quantity of cement is counted by charging scales automatically.

3.The aggregates/sand are fed by conveyor from stock pile or by wheel loader into the batching station. The concrete block mix is proportioned by weight into batcher, it is electronically controlled by using electronic scales to determine their weights which can guarantee to have a consistent quality from batch to batch.

4.The scaled materials are dropped into the mixer, then, the required water is added, and normally mixing process last for 5~8 minutes. The blended material is relatively dry when compared with concrete, so an efficient vibration is very important to that kind of nearly zero slump concrete mixture.

5.After mixing process, blended material is conveyed to storage bin(feeder bin) located above the block machine, the conveying method traditionally by belt conveyor or overhead tipper system.

6.Fixed amount of blended material are dropped into the filling box in each cycle.

7.The filling box is moved forward and brings the material into the mould. As the material is dry and viscous, oscillator and vibration help filling material into the mould evenly.

8.After filling the material into the mould, compression from the mould head and vibration from the vibration table are applied in order to consolidate the materials into dense concrete solid block units.

9.The fresh blocks lay on the pallet after releasing from the mould. The fresh blocks with the pallets are then transported to stacker. The stacker will stack the blocks with pallets around 5~8 layers for curing, and the green blocks are transported to the curing area by a forklift. ( or manual forklift to save the energy cost)

The abovementioned process is repeated to have continuous production and the shortest cycle time is around 15s. A face mix device will be added if it’s making doublelayer pavers. Face mix could add manually by shovel or automatically by conveyor according to customer requirement.

Curing: 

the ambient temperature~surrounding temperature plays an important role in determining the speed of the hydration process(hardening process). The warmer the air, the warmer the concrete and the quicker the concrete strength gain.

1. Natural curing: in the countries where the climate is favorable, green blocks are moist cured at normal temperature of 20-37(as in the south of China). This type of curing which at 4 days would normally give 40% of its ultimate strength. Initially, green blocks should be placed in a shaded area or enclosed chambers for about 8-12 hours (depends on relative weather conditions, temperature, humidity). After that, the blocks can be transported to an assembly yard for further curing for about 28 days to reach 99% of its maximum strength. For optimal final products, the fresh blocks need to be sprinkled daily, for the first 7 days (morning and evening) to maintain the moisture content for higher reactivity of cement with sand.

2. Practical suggestion for cuing

28 days curing to gain the full strength of masonry product is based on concrete which is slightly different when applying for the dry mix material for the block making. It is very commonly now cement is added with high quality flyash, and under the favorable conditions like the temperature and humidity, the compressive strength of the block/paver will gain up to 80% in less than 7 days curing. By using the #425 type cement and design the mix proportional at least 20% higher than the required compressive strength, the block/paver will be qualified to be delivered to the clients.

Land area and shaded area

The space required for one day’s production is around 200 sqms. Following sufficient air curing, the green building units are removed from the pallets on the next day, total curing are:200*1.5=300 sqms. Workshop area for machine is around 250 sqms. Total shaded area is around 550 sqms. For stocking yard the required area is around 7000 sqms.

Lifetime of mould:

A mould could last approximately 80,000-100,000 cycles. However, this totally depends on the raw material(hardness and shape), vibration time and pressure, precision.

Technology principle

Raw materials after screening and crushing, through  pressure and vibration, become one-time and final molding blocks.

 High efficiency:

 It could produce 28 bricks/board every 10senconds, as for the hollow blocks, it could produce 4pieces.

Raw materials:

Wide range of raw materials could be adopted such as fly ash, coal residue, coal wastes, chemical residue, sand, stone, concent, cement, construction wastes and so on. therefore, it is a new tpye of machine which has the characteristics  of energy conservation and environmental protection.

Product warranty: Through the ISO9001 and BV authentication (the certifications downloabalbe)
