Block Making Machines #3957607

fully automatic concrete block making machine

• solid block
• hollow block
• stationery type and egg laying type machines are available.

Cellular Lightweight Concrete Blocks are produced with a help of millions of nano-sized air bubbles into a cement based mixture. The Form Generator is developing the millions of air bubbles to produce highly stable blocks when its mixed with cement / fly ash sand and water slurry.

The % of cement, Fly-Ash and foam is depends on the required strength & density required. The hardened material consists of nano sized air bubbles within and its resulting in a light weight stable material. The dens various from 300kg / m3 to 1800kg / m3. Very good water curing will gives strength to the bricks.

• Low thermal conductivity.
• Thermal Performances 5 times better than clay bricks & 10 times better than RCC
• Interiors remain cool in summer and warm in cold wintry days.
• Savings in recurring energy costs in air-conditioning.
• Ideal material for applications in cold storage rooms.
• Up to 37-42db sound reduction based on thickness.
• Can fulfill required STC (Sound Transmission Class) rating.
• Gains Strength with Age
• UPTO 55% reduction in the weight of the walls, structural savings is very high. Perfectly suits high rise buildings and poor soil and earthquake areas.
• Makes construction 2 times faster than any other material.

PAVER BLOCK MAKING PROCESS:
Paver making by Vibrating Table method with semi automatic raw material feeding.
In this method we can manufacture paver by using PVC Moulds to any shape & size and color. The manufacturing process as follows;
1.RAW MATERIAL
2.RAW MATERIAL FEEDING
3.BLOCK MAKING
4.CURING THE BLOCKS

RAW MATERIAL:

• A.SAND / CRUSHER DUST
• B.CEMENT
• C.BABY CHIPS
• D.DYES AS PER COLOR REQUIREMENT
• E.CURING AGENT ( FOR FAST CURING OF BLOCKS)

RAW MATERIAL FEEDING:

SAND / CRUSHER DUST: - Will be stored in a Bin and feeding to the mixing hopper through a roller conveyer. The roller conveyers carry the material to the measuring box attached above the mixture.

CEMENT :- Will be feuded through the above conveyer itself.

BABY CHIPS : - Will be stored in a Bin and feeding to the mixing hopper through a roller conveyer.

The roller conveyers carry the material to the measuring box attached above the mixture.

DYES:- Directly feuded manually to the mixture

CURING AGENT :- Directly feuded manually to the mixture if required.

MACHINERY SET-UP FOR BLOCK MAKING :

Basically we are using 2 mixtures and 3 vibrating tables for Block making.

The primary mixture is for top layer mix which contains the color and the secondary mixture will carry normal concrete.

The size of the vibrating table is 3000mm length x 750mm width. Basically we are using 3 tables to give better strength to the blocks manufactured.

Raw material Mixing process:

MIXTURE 1 : This mixture having capacity of 250 kgs . The mixing ratio of the raw material is given below.

After mixing the mixture will be feuded to the PVC mould manually ( see the attached video). This mix will give you better finishing and strength to the blocks.MIXTURE 2 : This mixture having capacity of 500 kgs . The mixing ratio of the raw material is given below.

After mixing the mixture will be feuded to the PVC mould manually ( see the attached video) on top of the Ist layer mix.

This mix will give you rough finishing on the bottom of the brick to give better paving on the floor.

The plant capacity varies from 1500 m3 to 2500 m3 / shift of 8 hrs After 24 hrs all the moulds will be de-molded and cleaned for next day molding. The de-moulded blocks are stacked one-up-one for sales.
