How to choose equipment for the production of brick "Lego"?

O Brick production “Lego” we wrote in another article.

Now consider the most important factors affecting the quality of the “Lego” brick. They are:

  • Machine pressure;
  • quality of matrices;
  • Electronic sensors analyzing the size of the manufactured brick.

The pressure of the machine must be at least 130 kg / cm2, T.E. Machine with a single size matrix 12 * 24 cm. Must have a pressure of at least 30 tons.

The walls of the matrix must be made of metal with a thickness of at least 20 mm. Pay attention to its strength, otherwise Abrasive will destroy it in just a few days of work.

Quality of the matrix play a very big role, because the “Lego” brick is placed on each other, and any error can lead to the fact that the wall will be built wrong.

The presence of electronic sensors It is very important because manually understand the difference in the height of the product is very difficult. These sensors control not only the brick thickness, but also to the depth of frighting raw materials.

Machine performance

When calculating the business plan, one of the key points is the correct calculation of productivity.

Theoretical (maximum) productivity is many times different from what happens in practice. So, if you buy a low-power machine with a pressure of less than 30 tons with a capacity of 4 bricks per minute, we will get that for 8-hour working days we will produce 1920 bricks.

In fact, even with the most efficient use of time, you will receive about 400 bricks at the exit, which is about 5 times less than the calculated productivity.

This is due to the following factors:

  • Initially, when extracting from the machine brick is quite fragile, so much time goes to eliminate marriage. The failed brick is processed, which means a new mixture will be somewhat different in structure, and it will take time for additional adjustment of the machine.
  • Recreation time worker. Such mechanical work exhausts, so this idle time is necessary for full-fledged work.
  • Brick stacked on a special surface. And then after drying and partially typed strength shifted into special pallets, for which the time is also needed.
  • Also, time costs go to periodic cleaning of the matrix and its treatment with anti-recreational composition, loading raw materials and setting up the machine.
