Application of Laeg LD350 Series Inverter in Brick Press

I. Overview of Brick Making Machine

As its name implies, "brick machine" is the mechanical equipment for producing bricks. Generally, stone powder, fly ash, slag, slag, gravel sand and water are used as raw materials to make autoclaved fly ash bricks, autoclaved lime-sand bricks, aerated concrete products, etc. It is a good choice for large-scale, automated and modern production lines for making bricks with waste.

Baking-free brick machine is made of waste coal grindstone, shale, stone powder, fly ash, slag, slag, gravel, sand, etc., and does not go through the firing process, which is more environmentally friendly and saves resources, and has been vigorously promoted by the country. Since the end of June 2003, 170 large and medium-sized cities in China have banned the use of solid clay bricks for a limited time.

Second, the working principle of brick making machine

Crushing the aggregate with a jaw crusher, uniformly mixing with other ingredients, pressing and molding by a hydraulic brick machine, and autoclaving and curing with autoclaved gold to obtain a finished product.

Block forming machine has a high degree of automation, can produce many kinds of blocks (bricks) and large output, and is in a leading position in brick machine equipment. An automatic block forming machine is mainly composed of a vibration forming machine (main machine), a plate feeder and a brick discharging machine, among which the vibration forming device is the core part of the block forming machine.

The block forming machine relies on vibration and pressure to form and compact the concrete mixture in the mold box, so the selection of vibration parameters is very important to the performance of the block. Vibration parameters include vibration frequency, amplitude and vibration acceleration, etc. The vibration parameters generally used in domestic block molding machines are as follows: the vibration frequency range is 45~55Hz; The amplitude is 1~2.2mm; The vibration acceleration is 10~18g. Generally, the vibrator is driven by a motor or a hydraulic motor. Two shafts with eccentric blocks in the vibrator generate high-speed rotation in opposite directions, and the horizontal centrifugal forces cancel each other and the vertical centrifugal forces are superimposed on each other, thus generating vertical directional vibration.

Third, the application of Shenzhen Laeg inverter in brick making machine.

1. The starting current is small, the motor can be started smoothly, and the impact on the power grid and mechanical equipment is less.

2. Fast response speed, less acceleration and deceleration time, convenient for rapid frequency modulation and increased output;

3. The starting torque is large, and the motor can start smoothly with load;

Strong voltage adaptability, suitable for long-term stable work under harsh power supply conditions.
