security problems of Two Roll Mill
The two roll mill is one of the equipment with the highest incidence of industrial accidents in the process of rubber refining. Its working environment is the reason for the increase of its risk coefficient compared with other mixing equipment. The operator often contacts materials and rollers in the operation of the equipment. Most of the work-related accidents are brought into the roller by the operator. In order to ensure the safety of engineers and operators, safety training and a high safety equipment is essential.
The biggest problem with the traditional chain drive is that if an accident occurs in the process of operation, the machine will take the power cut to protect it. After a simple power outage, the two rollers of the machine will continue to rotate during the inertial process, or the brake holding system will still cause the employee to be continuously injured, and it is very difficult to deal with. A slight safety accident on the open mill results in a crush injury to the hand, which can endanger the whole arm or even life.
Lina machinery has been committed to R&D equipment for a long time, aiming at the safety problems on the machine is the focus of attention of Lina machinery, combined with Germany and Japan and other technologies to further research and development, Lina has obtained a number of patent technology. According to the natural reaction of the human body, add safety devices to all aspects of the machine. When the operator's hand is about to be clamped into the opener, our safety device will be touched by the spontaneous combustion reaction of the human body, and the machine will immediately carry out two instructions. The first immediately stops moving without inertia, and the second reverses 1/4 laps, even if the finger is slightly clamped in. The large open mixing machine designs the abdomen touch switch, according to the human body height arm length adjustment, whicn can make the operation master operation process only contact the roller face, if the master is pulled by the roller will touch this safety switch, will immediately stop to reverse.
Personal safety is more important than anything. It is a basic equipment requirement for employees to work in a safe working environment.
Less wear-resistant problems of Two Roll Mill
One of our guests said:"Before we open the machine for a long time to feel the gap between the roller more and more large closed, so thin effect is not good, your will appear this phenomenon? "And there is other customer said: "the mill with a long roll appeared Radian, both sides tight center loose, you will appear too?" More customers put forward: "our rubber is relatively hard, some open refiners will appear a short roll, you too?"
Synthesizing the reaction of many customers to the problems that often arise in the roller drum of the opener, the answer given by Lina Machinery is that this is a problem of roller material and finishing processing, and that the wear resistance of the roller is not strong enough to cause serious wear and tear of the roller for a long time. The hardness of roller is not enough to appear roll arc phenomenon. The ductility of the roller is not good for the 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, and 72 hours of advanced treatment of the surface is also one of the important keys to determine the wear resistance of the roller.

Low accuracy problem of Two Roll Mill
The two roll mill is mainly used for mixing and producing the rubber material. The preformed sheet requires high precision, and can not appear the phenomenon,such as shoulder effect or non-uniformity on both sides. If the sheet is not uniform, it will cause the material to be thickly and unevenly after forming,which can cause unnecessary waste. The main reason for the low precision of the mill is the roller supporting shaft, and the roller precision and material quality will also affect the precision of wire rod and so on.
Lina machinery uses manual digital display to solve the problem of precision. The precision requirement of roller making is very strict. It will be tested for 72 hours before leaving the factory. At the same time, the accuracy and service life of skf bearings are better than that of ordinary bearings, but the traditional open machine nylon sleeve or copper sleeve belongs to the early roller support parts with deviating from the center distance after wear, which has completely lost the precision requirement and has a great impact on the mixing, so at this mement to overhaul doesn`t make sense with a huge cost waste.

High noise problems of Two Roll Mill
According to a survey of 100 thousand people by 152 experts, the average factory employee, if exposed to the noise above 90db for a long period of time, will cause hearing loss, and if the noise is above 85db, it will cause hearing impairment after 8 hours. If the noise frequency is above 1000hz, it will cause temporary hearing impairment, and if the noise frequency is in 4000~6000hz, it will cause permanent hearing impairment after long exposure.
Under high frequency noise, the tolerance limit of auditory organ is exceeded, and the pain to the ear is produced, which will cuase distasteful, impatient, inefficient, irritable, anorexia, dyspepsia and other symptoms.
The traditional open mixing mill, which makes a lot of noise in the process of operation, makes the workers work in a bad environment as if the train were passing by. Most customers report that operators are becoming increasingly difficult to find,especially young employees when their company uses traditional open mixing mill.
According to the problem of noise, combining with the fitness of human body to sound, Lina machinery can reduce noise in the whole process, such as motor, reducer, roller support and transmission device, etc. Its reducer can increase its service life and reduce noise at the same time as it is customized in Guomao. There are only 30 db. in the operation of the small open machine. The problem that the customer encounter is the problem that Lina machinery is working to solve.
