The Hartmann MR2250 is a semi-mobile concrete batching plant designed for high-volume ready-mix concrete production. Semi-mobile plants of this type are used by concrete suppliers, construction firms, and large building projects where a permanent on-site batching facility is required but eventual relocation is anticipated. Hartmann is an established manufacturer of concrete production equipment serving the construction and concrete industries.
This factory-new 2024 unit delivers a maximum output of 100 cubic metres per hour and is built around a twin-shaft BHS mixer with a batch capacity of 2.25 cubic metres (type DKX 2250/3375). The aggregate storage system comprises four bins, each with a nominal capacity of 36 cubic metres, expandable to 45 cubic metres per bin. The bins are designed with internal compartmentalisation, permitting flexible division into smaller chambers to accommodate multiple aggregate types—for example, three 36-cubic-metre compartments plus two 18-cubic-metre compartments for five aggregate grades, or alternatively two 36-cubic-metre compartments plus four 18-cubic-metre compartments for six grades.
Material dispensing is managed via sixteen gates, each equipped with an actuator and solenoid valve. An additional aggregate dispenser with belt conveyor provides secondary material handling. The skip is fitted with a rope winch, brake, and inverter. Weighing and metering systems include electronic scales for chemical admixtures, aggregates (via conveyor belt), cement, and water, with both coarse and precision water-dosing modes. The plant is controlled by a dedicated computer control system housed in a 6-metre control container.
Cement storage consists of four silos, each with 65-tonne capacity. The mixer is equipped with winter insulation and an enclosed winter jacket. The plant includes an integrated mobile concrete recycling system and a compressor. All electrical documentation—operating manual, schematic diagrams, installation instructions, dimensional drawings, and CE declaration—is provided. The machine has never been operated and is ready for collection ex works. Transport and assembly are available as optional services, as is configuration of the control system software in the customer's chosen language.
