Linnhoff’s Base Stabilisation Plant series has a primary function of producing plant-mixed graded aggregate base for the Base Course of road pavement. Indifferent countries, the terminology used for this base course material varies. Such names include graded stones, wet-mix, Cement Treated Base, Roller Compacted Concrete (RCC) & etc. The material encompasses a continuous dense grading envelope, right down to the fine fraction for its density.

For a proper graded base course material, hoppers receive well graded crush rock and sand, with a continuous pugmill mixer, there materials are thoroughly mixed and water introduced at optimum moisture content. At times depending on the material specifications, cement or lime or flyash is also introduced in the mixer.

From the Base Stabilisation Plant, these road base materials are then spread by motor graded or paved using asphalt finisher in layers, and compacted with rollers. Upon compaction, the road base is then able to be trafficked without noticeable impression by construction equipment. Subsequently, asphalt hotmix is paved on top of the road base.

ADVANTAGES
› Uninterrupted Production
› Accurate Proportioning
› Homogeneous Blending

MAIN COMPONENTS

Cold Feed Hoppers
Sand and graded aggregates are compartmentalized with side walls in a containerized structure for easy shipment, transportation and installation. Each feeder having shaft mounted gear motor and frequency inverter control with loadcell connection ensuring accurate measurement of plant production.

Continuous Twin Shaft Pugmill Mixer
Linnhoff’s uncompromising counter-rotating motion of twin mixing shafts with a very rugged mixer construction ensures continuous uninterrupted production of materials. Specially cast paddles arms and tips as well as durable liners are made of Ni-Hard material, a protection against wear. Sturdy drive of Linnhoff’s mixer coupled to the shaft elimates misalignment and wear under heavy load.

Computer Control
Computer controls housed in a control cabin with glass windows for convenient vision of plant surrounding is dustproof insulated and air-conditioned. User friendly computerized system shows full graphical plant visualization and equipped with frequency inverters, Programmable Logic Controller (PLC), Computer CPU, Voltage Stabilizers & etc.
