Processing Centre

It takes thousands of dedicated workers and state-of-the-art equipment to transform raw marble into the dazzling products we see in homes and commercial spaces. At the R K Marble processing centre in Kishangarh, over two million cubic feet of raw marble is processed each year for customers throughout the world. The processing of marble slabs includes following activities:

1. Receipt of raw marble blocks:

The raw marble blocks received at factoryare unloaded in the gantry yard with the help of Gantry Cranes.

2. Dressing of Marble Blocks:

Dressing of Marble BlocksThe dressing machine operator dresses the marble block from all the sides for removal of natural defects.

3.Block reinforcement:

Before sending the fragile rough marble block to gangsaw machine for sawing, the blocks are reinforced with fibre glass net and a binding agent.Usually for sides of the block are reinforced. The block is then left for about 24 hours for curing. This process ensures minimum breakage of slabs during the sawing process.

4. Sawing Process:

Sawing ProcessThe dressed and reinforced blocks are shifted to the Gangsaw trolley as per the size of the Gangsaw machine. The block is fixed on the trolley with a wooden wedge and a mixture of Gypsum with wood wool at the desired angle.The trolley is placed below the blades for sawing.

5.Net-reinforcement of marble slabs:

Glass fibre net is applied on back face of the marble slabs to strengthen the slabs which are fragile and to enable safe handling and transportation. The glass fibre net is peeled off before fixing by the marble masion at the site.

6.Grinding Process:

Rough Grinding of Marble slab - After the 1st stage of epoxy filling the marble slabs are processed in the Grinding Machine and then these processed slabs are shifted to the RESIN line for final epoxy resin treatment.

7. Resin Treatment:

Resin Treatment

" Most of the colored material have hairline crack,minor cracks, which required to be treated. We have state of art machines to do this job, which enhances the finish of our product.The slabs are first dried in the heating chambers,high quality resin is applied, vacuumization is done to remove air bubbles, the polymerization of the resin is done through heating chambers. This process fills even the invisible cracks and produces one of the best quality possible".

8. Polishing Process:

Polishing Process Polishing process is done with the polishing machine "LEVIBRETON Model KFG 2000/018". The machine is used for making the surface even and then polishing marble slabs for getting a smooth and shiny surface.

The machine performs the following operations to achieve a smooth and glossy surface:

  1. Loading of the marble slab on a Tilting Roller conveyor by an Arm Crane
  2. Feeding the Slab to the polisher by free Roller conveyor
  3. Grinding of Slab surface by initial Grinding Heads
  4. Polishing of the Slab by Polishing Heads
  5. Drying of the Slab by drying unit
  6. Feeding to Tilting Roller conveyor by Motorized Roller conveyor
  7. Unloading of Slabs by Arm Crane
