WET MIX MACADAM PLANT:

Wet Mix Macadam Plants also known as Soil Stabilizing Plants are employed for producing homogenous mixture of aggregates, sand, cement and water. This mixture is layed in base or sub base preparation of rigid or flexible pavements.

It is continuous type plant where in different size aggregates and sand stored in multiple feeder bins are discharged by each bin feeder belt in desired proportion to gathering belt. This mix material is then conveyed by gathering belt to Pugmill mixture where the mixture of aggregates and sand is mixed with water and cement to produce the homogenous mixture of all ingredients. The homogenous mixture is then conveyed to storage silo or trucks for lying at site. All the ingredients of the mix are metered in required proportion prior feeding to the Pugmill mixture.

The main components of Wet Mix Macadam Plant are Multiple Feeder Bins, Collecting Conveyor, Pugmill Mixture, Load out conveyor, Water storage tank, Cement silo, Storage Silo and Control Panel.

Output capacity: 60 TPH, 100 TPH, 160 TPH, 200 TPH.

AGGREGATE MULTIPLE FEEDER BINS:

Stores, meters and supply in required proportion different size of cold virgin aggregates for the production process.

Feeder bins are engineered and constructed for maximum durability. They are supported by a heavy duty steel foundation with support gussets, tie ins and stiffeners that lengthens the overall life of the bins.

Tapered side walls of bins ensure even flow of aggregates eliminating plugging & bridging problem.

Each bin fully adjustable radial gate system in conjunction with variable speed endless multiply feeder belt controls aggregate flow rate and transfers them to the gathering conveyor as per set percentage.

Rubber sidings are provided to prevent leakage between bin bottom and belt surface.

Bin vibrator is fitted on one bin for free flow of fines.

Multiply rubber belt gathering conveyor running beneath the feeder bins collects the different size aggregated discharged from them and transfers to slinger conveyor through single deck scalping screen.

COLLECTING CONVEYOR:

Receives the different size aggregates and sand from the feeder bins and transfers to pugmill for mixing with water and cement.

Multi ply rubber belting running over idler rollers fixed in stand bolted to robust frame constructed from structural steel.

Drive system consisting of TEFC motor and shaft mounted gear box.

Uniformly placed idler & return rollers support the belt without any sagging.

PUGMILL:

Produce homogenous mixture of aggregates, sand, water and cement.

Depending on the capacity they are single or twin shaft counter rotating type.

The wall of the pugmill is lined with ni-hard replaceable tiles to take care of the abrasion caused by the mix material.

The paddle arms fitted on the shaft holds the replaceable ni-hard blades.

The shafts are mounted on the heavy duty antifriction thrust bearings.

Drive to the shaft is through electric motor coupled to heavy duty gear box and fluid coupling.

LOAD OUT CONVEYOR:

Transfers the mix produced in pugmill to storage silo or truck.

Multi ply rubber belting running over idler rollers fixed in stand bolted to robust frame constructed from structural steel.

Drive system consisting of TEFC motor and shaft mounted gear box.

Uniformly placed idler & return rollers support the belt without any sagging.

Gob hopper fitted at the discharge end of the conveyor is with hydraulically operated gates as per set timers to deliver the mix in lump thus avoiding segregation.

Power pack unit is provided for operating the gates of the gob hopper.

Water Tank:

Stores & supply the water required for the mixing with other ingredients in pugmill.

Fabricated from M.S. plate of adequate capacity as per the output capacity of the plant.

Consists of Water Pump, Piping and Flow meter to meter the water in accurate quantity as per the mix requirement.

CONTROL PANEL:

It is centralized control panel from where all the operations of the wet mix plant components are controlled.

The body of the panel is fabricated from CRC sheet duly Powder Coated to protect against weather effect.

It is equipped with the emergency stops, on / off buttons, selector switches, riders, volt meters, current meters, totalizer on the front desk with ease access to operator in logical manner.

Other electrical items like MCB, fuses, drives, interlocks, starters etc. are housed on the rear side of the panel.

Totalizer displays all the set parameters.
