The development of China's fire-free brick making machine can be traced back to the 80s of the last century. At that time, China took the lead in developing a squeeze-type eight-hole brick making machine, which pioneered the fire-free brick making machine. In recent years, China has forced the use of clay bricks (red bricks), and most of them have been put in place. The new building materials market, such as non-burnt bricks, hollow bricks, and aerated concrete blocks, has never been more prosperous. Many companies are also optimistic about this huge market prospect. But how to buy a brick-free machine? How much is the cost of the brick-free machine? The brick machine website Xiaobian talk about it:
The equipment for the non-burning brick machine generally includes: a batching machine, a mixer, a cement bin, a weighing system, a molding machine, a stacking machine, a computer control cabinet, and the like. Some equipment can be purchased on its own to save money.
The production line for the purchase of non-burning brick machine equipment should pay attention to the qualifications of steel, welding, vibration, cloth, hydraulic pumping station, computer control cabinet and enterprise; because the bricks are always vibrating during the production process, the size and strength of the steel And welding is especially important. The vibration mode generally has motor vibration and hydraulic vibration; the motor vibration is cheap but the effect and the service life are not as good as the hydraulic vibration. The cloth is separated from the main unit and connected. Since the vibration of the brick-free machine is accelerated, the liquefaction of the cement is accelerated, so that the unevenness of the raw materials affects the strength of the brick. Long-term operation of the hydraulic pump station will increase the temperature of the hydraulic oil. A certain temperature will affect the pressure and directly affect the quality of the brick. The strength of the brick without the pressure is not enough. The cooling system of the hydraulic pump station is not cool. The effect of water cooling. The computer control cabinet can control the pressure; the pressure is too large to waste raw materials.
summary
The price of the non-burning brick machine is determined by the process of each equipment. The good cost-effective brick-free machine production line depends on whether the complete design scheme of the brick-free machine manufacturer is reasonable and after-sales service. I hope to help you in China. Brick machine network!
