Complete Pugmill Plants are designed inhouse, and tailor made to requirements of our clients from around the world. The plants are currently manufactured from 200 to 600 TPH capacity to cater to varied requirements of our clients. GPE is in a unique position to offer the complete Pugmill system (Soil Stabilizations Plants) on a single source responsibility basis. Products with temperatures upto 250℃ can be handled by efficient use of Special Insulating Material, Ventilation System, Special Mixer Sealing and Belts with capabilities to handle high temperature products.
Aggregates are stored in multiple compartments mounted on a rugged Industrial Steel Frame, size of which is decided based on the specific requirements of the client. Multiple cones discharge aggregates simultaneously by means of continuous weighing volumetric conveyor belts onto the extractor belt to ensure precise measuring on a continuous basis at all operating times. Cement is stored in a Cement Silo, and conveyed using a screw conveyor to a Cement measuring hopper. Volumetric measurement of Cement in Cement Hopper, equipped with vibrator, ensures correct volume of Cement is dosed at all times. Water is also measured volumetrically for precision.
A continuous twin shaft mixer made from Industrial quality, high abrasion resistant annealed steel is used in all our pugmill plants. with the following properties:
A PLC controlled Touch Screen Control system ensures that the production is optimized at all times by proper control of all functions. The Control System has complete command over all functions of Extracting Belts, Vibrators, Conveyor Belts, Screw Conveyors, Water System, Continuous Mixer. Recipe management can also be done by the Control system thereby eliminating the process of repeat entry of the required parameters.
Cement Treated Base : One of the primary products manufactured by our Pugmills is the Cement Treated Base (CTB) used as Road base under the final Asphalt Layers during construction of roads. Precise dosing of cementitious materials like cement, asphalt & flyash etc gives great strength to the final mix. Road Base is used as a low cost, high strength to the final road. Typically, road base would be transported in Dumper Trucks, spread evenly on the area and compacted repeatedly using rollers.
Roller Compacted Concrete (RCC) : A very precise dosing of Cement and water to produce concrete with low slump, to be finally placed using Asphalt Paving Equipment with further compaction by heavy vibratory rollers. RCC is liberally used in construction of Heavy Duty Structural projects like dams. The mixing arms, also known as paddles, use heavy force to produce a homogeneous mix of RCC by vigorous mixing the aggregates together.
Cold Mix Asphalt : Manufacturing of Cold Mix Asphalt (CMA) is done by mixing asphalt in cutback or emulsified form with precisely dosed aggregates. Our systems come prepared to be used upto 2500C to ensure proper mixing at all times. The Pugmill Continuous mixer in such plants is properly insulated with ventilation; and all handling equipment is capable of handling high temperature products on a continuous basis. The aggregates accepted in this case may vary from granular soil with high particulate matter to dense crusher material making the whole system as a very flexible one.
Hazardous Soil Mixing (Oil Recycling) : Our pugmills are very beneficial in recycling of all types of bio hazardous oils by mixing them with aggregates and cement in our continuous mixer to produce concrete that stop leaching of contamination. Additional cleaning/stabilizing chemical may also be dosed into the mix to ensure stability of the eventual mix. Normally, such products are used as a landfill in different parts of the world.
Mine Backfill : GPE Pugmills are also used to manufacture low strength concrete suitable as a backfill for many many applications like abandoned Mines, Shafts & Pipes,manholes and utility Trenches.
