MOBILE PLANTS AND MIXERS IN ZIMBABWE.

When requiring mobile concrete mixing and transportation units for a job site, the traditional method is to use a continuously rotating barrel/cylinder on the rear of the unit (truck or off-road equipment, depending on the size required and application). The aggregates (materials such as cement, sand, stone and water) are then put into the barrel and mixed (barrel rotation) to produce the end product (concrete). Once the product has been mixed it has to be used as soon as possible, as the longer it stays in the barrel the harder the mix will become and eventually will be unusable. The possibility of mixing more than necessary is always a concern when building, as there is generally much waste which affects both production planning, as well as the budget.

BLEND Plants has completely redesigned this method with their innovative equipment:

1. The aggregates, cement and water are stored in separate compartments, which are either loaded at the site, or pre-loaded to serve a number of sites.
2. Once the operator has been advised on the percentages to be included in the mix, these figures (including the amount to be mixed) are inserted into an onboard computer and the mobile unit then produces the exact amount required by the customer.
3. Essentially, this process negates the method of mixing first to carry to an area on the building site later.
4. The waste factor is also minimised, as the aggregates can be stored overnight, even if all the material has not been used previously.

BLEND Plants mobile batching solutions (E-Series) This equipment can produce from 0-70 m³/h depending on the mix design required.

The large production plants (A-Series) has options to hold either two, three or four aggregates and produce up to 120 m³/hour.

For cement storage solutions, BLEND Plants provide the option of four different horizontal silos with holding capacities between 16 m³ and 42 m³.

Both the large production units and the silos can be fitted with piston legs, which means they can be transported on a flatbed trailer and moved with ease between locations, without requiring the use of a crane.

The table below illustrates the differences between a traditional unit that much of the market uses today and the mixed-on-site unit that BLEND Plants offers as an alternative for your business.
