Fibo Batching Plant Output Guide

The table below shows the outputs for Fibo batching plant. There are two tables.

Table 1 – Wet batched concrete using an M25/C20 concrete mix as an example.

Table 2 – Dry batched concrete using an M25/C20 concrete mix as an example. Dry-mix is used to dose drum mixers, and the mixing process happens by the drum wagon on the route to the site.

The different sizes of the batching plants are 2200 litres gross 1400 litres net, 1800 litres gross 1000 litres net and 1200 litres gross 800 litres net.

For example, the 2200 model produces 1.4 m3 of concrete per mixing cycle. Therefore if the output were 40 m3 per hour, the number of cycles would be 60 minutes / (40 m3 /1.4) = 2.1minutes per cycle.

Definitions

Pre-mix – is when the sand and stone is pre-mixed before batching. The fibo batching plant can pre-mix the sand and stone, and this can then be stored for use.

The advantage of using a pre-mix is that all the bins can be dosed at the same time, making it faster to dose the mixing pan.

Pre-weight cement – is when the cement is weighed before dosing. Cement pre-weigh uses the integrated main cement silo with weight cells on the feet, or a pre-weigh dosing cell can be attached to the plant on separate weigh cells as well.

The advantage of using pre-weight cement is that the cement can be batched at the same time as the sand. The computer already knows the weight of the cement and makes the allowance. Using pre-weight cement makes the batching process faster by 4/5 m3 per hour and improves the batching accuracy from +- 3% to +- 1%.

Dosing Station – is a dry batch plant with no mixing pan. The plant doses onto a conveyor and then into a drum wagon for mixing. The advantages are less cleaning, and the plant is more competitive.
