The Hartmann Semi-Mobilny węzeł betoniarski Hartmann MR2250 is a semi-mobile concrete batching plant designed for high-volume ready-mix concrete production. Hartmann is an established manufacturer of concrete mixing and batching equipment serving the construction materials industry. This plant combines stationary mixing capacity with semi-mobile configuration, allowing relocation while maintaining full production capability on site.
The unit is factory-new and unused as of 2024, never having produced concrete. Maximum production capacity is 100 cubic metres per hour. The mixing unit employs a BHS twin-shaft mixer with a drum volume of 2.25 cubic metres, model type DKX 2250/3375.
Aggregate storage comprises four bins of 36 cubic metres each, with the option to expand to four bins of 45 cubic metres. The bins are pre-configured for internal division into multiple compartments, allowing segregation of up to five or six different aggregate types—for example, either three 36-cubic-metre bins plus two 18-cubic-metre bins, or two 36-cubic-metre bins plus four 18-cubic-metre bins. The bin system includes 16 gates, each operated by a hydraulic cylinder and solenoid valve.
An additional aggregate feeder with belt conveyor is provided. The skip is equipped with rope hoist, brake, and inverter. Chemical admixture dosing employs an electronic scale; aggregate weighing is carried out via electronic scale integrated with the conveying belt system. Cement and water are both electronically weighed, with water dosing offering both coarse and precision control options. The plant is managed by a computer control system housed in a 6-metre control container; the control system can be configured in any required language.
Auxiliary equipment includes a compressor and four cement silos of 65 tonnes capacity each. Winter insulation and enclosure are fitted to the mixer. A mobile concrete recycling unit is included.
Documentation provided covers operation manual, electrical schematics, assembly instructions, dimensioned drawings, and CE declaration. The machine is located in Poland. Transport and assembly options are available.
