24-inch open mill | automatic rubber mixing machine factory direct sales

Personal safety is more important than anything else, and allowing employees to work in a safe working environment is the most basic equipment requirement for Leena. The problem of the open mill not being wear-resistant
Some customers said: After using our previous open mill for a long time, it felt that the gap between the rollers was getting bigger and bigger and could not be closed, so the thinning effect was not good. Will this happen to yours? ? Some customers also said: The rollers of the open mill in the factory have become curved after being used for a long time, and the two sides are tight and the middle is loose. Will this happen to yours? Some customers even asked: Our rubber material is relatively hard, and short rollers may appear in some mills. Will yours do this?
Based on the feedback from many customers on some problems that often occur with open mill rollers, the answer given is that this is a problem with the material and finishing treatment of the rollers. The wear resistance of the rollers is not strong, resulting in long service life of the rollers. Serious wear problems occur, and the hardness of the roller is not enough, resulting in roller arcing. The toughness of the roller cannot cause short stick phenomenon. To solve these problems, the material of the roller is the core, which is one of the keys to determine the toughness and hardness of the roller. The surface + hour depth treatment is also one of the important keys to determine whether it is wear-resistant.
The problem of high energy consumption of open mills
Some customers asked why using your open mills of the same model saves more energy than buying other companies’ ones before. This issue was raised by the company's engineers after they returned to China for study in 2006. As the cost of industrial electricity gradually increases, if energy consumption is reduced, customers will save production costs, which will allow corporate equipment to occupy a wider market. market.
After two years of improvement, the first generation of new open mills was launched. In fact, there are three main reasons for high energy consumption. The first reason is insufficient torque. When the torque is insufficient, the motor needs to be increased to increase the torque. The second reason is that energy is lost rapidly during the conversion process, causing unnecessary energy waste. The third reason is that the resistance caused by the machine transmission and support structure increases energy loss.
The first generation of new models emerged when the three main reasons were integrated and solved
The fourth generation has been launched, and its energy consumption is reduced by more than 3% compared with traditional open mills (it varies according to different materials) . Lina's open mill uses customized accessories to minimize energy loss in the process of converting high speed into low speed and high torque. The speed ratio gear adopts hard tooth surface helical teeth, which mesh closely to reduce noise while transmitting energy stably.
The problem of low precision of the open mill
The open mill is mainly used for mixing and tableting of rubber materials. The precision of preformed tablets is high, and the shoulder pole effect or unevenness on both sides cannot occur. If the sheet is unevenly produced, the thickness of the material will be uneven after molding, which will cause unnecessary waste.
The main reason for the low accuracy of the open mill is the roller support shaft. At the same time, the accuracy and material of the roller will also affect the precision of the screw rod, etc.
The machine adopts manual digital display for accuracy issues. The roller production accuracy requirements are extremely strict. It will be tested for an hour before leaving the factory. At the same time, the precision and life of bearings are better than ordinary bearings. However, traditional open mill nylon sleeves or copper sleeves are early roller support accessories. They will deviate from the center distance after wear. This means that the accuracy requirements have been completely lost, and will It will have a great impact on mixing. At this time, it will need to be overhauled, causing a lot of cost waste. It will have no maintenance value after a long time.
