ANSWERS
 
1. Do I have to buy a whole plant with all machines to produce concrete blocks?
Answer: No. But if you want to get maximum production speed and save on numbers of workers [paychecks] it's better to invest little more in the beginning then later to pay more and more.
2. What are the basic machines that I need for a start?
Answer: Block making machine, mould [moulds], pan mixer, manual vehicle for transporting concrete mixture.
3. How to decide what type of machine is the best for me?

Answer: There are many things that can decide which machine is the best for your business.
If you have money buy the best machine or plant based on [UNIVERSAL 1000 FA] and you solved all the problems.
First, you have to decide what concrete elements you want to produce.

Concrete blocks
If you want to make just concrete blocks without importance of production speed then you should consider buying of:
Euroblock 12
- semiautomatic model.
Higher speed and performance - Euroblock 12 full automatic model.
NOTE: We also have some better [more expensive] solutions for movable block making machines [contact us].

If you want to buy some stationary model you should consider Economic 300 which is just good for basic concrete elements, not for paving stones.
Yes you can use Economic 300 for paving stones, but mostly for one layer. For double layer pavers you have to manually pour colored mixture over first layer.

Concrete blocks and paving stones
If you want to make concrete blocks and paving stones with importance of production speed then you should consider buying of Universal 400 FA - semiautomatic model.
Higher speed and performance - Universal 800 FA automatic model with full automatic system.
If you want to buy some STATIONARY model you have to check our Plant comparation document where you can see the difference between the machines, production speed and included other machines like pan mixers, etc. Higher production speed needs higher capacity of mixing concrete mixture.
You can save some money if you buy semiautomatic models or even manual, but it will take hiring more workers for the job and production speed will be lower.
 
4. How system works in the complete block making plant? How's system of production goes in plant?
Answer: Check out The scheme of in line system of UNIVERSAL 600 FA based plant. There you can see all machines needed for complete solution of automatic production.
 
5. How many working pallets do I need producing
900 blks/hour or 7200blks per 8hr/shift?

Answer: 900 pallets for 1 shift + 900 empty for next shift = 1800 pallets total.
 

6. What is the price of working pallets?

Answer: 18-40 EUR/pallet in Austria, factory made.
 
7. What is CUBER?
Answer: Device for packaging elements after they came out from lowerator on transport track. Usually semiautomatic. Worker has to control it. Full automatic models are very expensive and may cost up to 90.000 EUR.
 

8. Is the quality and paving stones and blocks produced by the movable machines good as those produced by stationary machines?

Answer: YES. stationary system is little better quality, but both systems are satisfy block quality standards.
 
9. Don't I need a covered space to protect the fresh elements from rain and to protect the machine itself during production while raining?
Answer: YES IF YOU HAVE LOTS OF RAINING DAYS. You don't work on rain conditions.
 
10. Where can I see the SCHEME [plan] of all machines in the plant?
Answer: CLICK HERE, and download wished SCHEME.
 
11. How many working pallets fit into one level of the elewator, lowerator ?
Answer: 2 pallets. Elewator, lowerator has 10-12 levels.
 

12. What is an acceptable mix ratio?

Answer: The ratio of cement, sand and stone chips or gravel in the raw material mix determines the properties of hollow concrete blocks. A ratio of 1:3:6 [cement : sand: stone chips] confers higher strength, while a ratio 1:5:6 can be employed for normal load bearing construction. The water to cement ratio is usually 0.4:1, which is a little less than half the amount of water to cement.
 

13. Do I need a machine for every type of brick or block that I make?

Answer: No. All of our machines can be fitted with any mold that was designed for that machine. That includes, paver molds, hollow block molds, solid block molds and all brick molds. So for example, today you can produce 6" blocks and tomorrow you can produce 4" blocks on the same machine by just changing the mold. The following day you can produce bricks. All you will need to do is remove one type of mold and replace it with another. These are quick change molds and the entire process takes about twenty minutes.
