summaryThe 2ZM series vibration mill is a new type of high-efficiency and energy-saving grinding equipment. It has significant advantages over traditional rotary mills in grinding fine and ultrafine powder materials. The machine has the advantages of high vibration intensity, high grinding efficiency, low power consumption, low noise, compact structure, and easy installation and maintenance, with an efficiency increase of 2-5 times and a 20% -30% reduction in energy consumption. This machine can be widely used in various industries such as mineral processing, building materials, grinding materials, powder metallurgy, electricity, ceramics, refractory materials, magnetic materials, chemical industry, food, etc. It is an ideal replacement product for ball mills.Structure and working principleThis machine is mainly composed of a chassis, a body bracket, a soundproof cover, a body, a grinding cylinder, an exciter, a lining plate, an elastic support, a grinding medium, and a drive motor.1. The chassis supports the body with elastic support and maintains the flexible connection distance between the driving motor and the vibrating body unchanged;2. The soundproof cover is used to block the noise emitted by the grinder during operation, in order to reduce the impact of noise on the entire work area;3. The body is fastened with a grinding cylinder and equipped with an exciter;4. The grinding cylinder is the working body of the vibrating mill, used to contain the grinding medium and abrasive material;5. The exciter is used to convert the rotational torque of the motor into periodic vibration of the mill;6. The lining plate is tightly attached to the inner wall of the grinding cylinder to protect it. When vibrating and grinding materials inside the grinding cylinder, there is also significant wear on the inner wall of the grinding cylinder. Installing an easily replaceable lining plate inside the grinding cylinder can improve the service life of the entire machine;7. Elastic support keeps the grinding machine body in an elastic state and effectively isolates the vibration impact on the base when the body vibrates;8. The grinding medium is the grinding body of the grinder, used for impact grinding of materials;9. Drive the motor to provide energy for the vibration grinding of the mill.Connect the power supply and drive the motor to rotate the exciter through a flexible coupling, generating sufficient excitation force to cause the mill body to enter a cyclic vibration state. The oscillation force is continuously transmitted to all materials loaded into the grinding cylinder (i.e. the medium and the ground material), and through the mutual impact between the grinding medium and the ground material, the ground material is crushed and finely ground.Installation and adjustmentThe chassis of the vibration mill should be installed on a cement foundation, and the chassis should be leveled and aligned. The horizontal error of the lower part of the supports on both sides of the cylinder shall not exceed 0.5mm. After leveling and aligning the chassis, the foundation bolts shall be fixed firmly with secondary grouting. The required anchor bolts for installation shall be provided by the user.After the installation of the vibration mill, the centerline of the cylinder should be 8mm higher than the centerline of the motor before the medium is loaded. After the medium is loaded into the cylinder, the centerline of the cylinder should be 11mm lower than the centerline of the motor.3. The filling rate of the medium in the cylinder is 65-75%, and a filling rate that is too high or too low cannot achieve the best grinding effect.4. The cooling water circuit of the exciter should be connected in parallel.5. There is noise generated during the operation of the vibration mill. In order to reduce environmental noise, the vibration mill should be sealed with a soundproof cover.After adjusting the vibration mill, the soundproof cover should be installed. Each sealed dust-proof part and soft connection interface should be in effective working condition. If there is any damage or failure, it should be dealt with or replaced immediately.Usage and maintenance1. The vibration mill requires uniform feeding, and the feeding amount should be adjusted appropriately during machine testing. The fixing bolts on the vibration equipment are prone to loosening, and the bolts should be checked and tightened again before starting the equipment.2. Start the vibration mill empty for 20 seconds before feeding into the mill. Stop feeding before stopping the machine, and stop again after about 20 seconds.3. The medium in the vibration mill needs to be worn and consumed. When the medium is consumed by 10% -15%, or when there is a change in the particle size of the discharged material, new medium should be added according to the original size of the medium added. At the same time, the medium to be ground should be checked, and the medium that is too fine should be selected.
