Metal pulverizer is a professional machinery that can crush large sized solid metal materials to the required size. According to the size of crushed or crushed material, the mill can be divided into coarse crushing machine, medium crushing machine, fine grinding machine and ultra fine grinding machine. This machine is mainly composed of worm gear reducer motor, casing, frame, screw cutter plate, driving shaft, driven shaft, big gear, small gear, etc.
In the crushing process, the external forces applied to the solid are crushed, cut, impact, and grind four kinds. The pressure rolling is mainly used in coarse and medium crushing, which is suitable for crushing of hard materials and bulk materials. Shearing is mainly used in crushing, suitable for the grinding of malleable materials; The impact is mainly used in crushing, fine grinding and ultra-fine grinding, suitable for crushing of brittle materials. Grind mainly in fine grinding, fine grinding, suitable for small pieces and fine particle crushing. The actual grinding process is often several forces acting at the same time.
Working principle
The metal crushing machine can be divided into two types according to its working principle: 1: use the double-axis or single shaft to rotate at low speed, and use the knife disk to cut, cut, tear, pull. Through gear change transmission to the driven shaft, the active shaft of the dynamic knife and the static knife disk of the shell form relative motion. The spiral toothed cutter on the active shaft is staggered in order to make the material enter, and it is squeezed, torn and sheared to break the material. 2: the long metal cuttings are torn and broken by high-speed rotating impeller. The spindle of high speed rotation (about 1, 000 RPM) is connected with a series of round steel plates, and the circular plates rotate on the spindle. The round board has 4~6 small gears made of manganese steel. The pinion rotates freely on its own small axis. Long and messy clumps of scrap metal from top opening into the machines, high-speed rotating plate gear on the ground, tear into small pieces, the outflow from the bottom of the screen hole mesh size can according to the request of scrap metal broken broken particle size selected.
Metal crusher use motor drives the rotor, the basic principle of extrusion under the high speed high torque motor driver, gouge in the crushing cavity can be fully and effectively finely, to be broken apart into accord with specifications of the broken objects. Broken material through air swirl grading system, put the pot and the pot of separation, and the whole system is equipped with dust removal device, will be produced in the process of production dust pollution harm to a minimum. The equipment mainly has the advantages of high yield, low energy consumption, high efficiency and evenness. And in the use of the device, low noise, no pollution, easy to operate, easy to maintain.
Components comprise
Gear motor adopts direct worm gear and worm gear motor, installed directly on the crusher drive shaft, gear transmission by size to the driven shaft, the master-slave shaft spiral serrated knife form the relative motion of the plate. The spiral gear cutter in the moving shaft is staggered to make the material enter, and it is squeezed, torn and sheared to break the material. Because the required broken metal materials are mostly brittle and hard, the chip, small gears and iron sieving machines must be made of hard and resistant hard materials. A flywheel is mounted on the main shaft to make the main shaft have greater torque when breaking scrap iron. In addition, the spindle is best driven by the hydraulic coupling to remove the high peak current of the motor and absorb the vibration of the spindle. When shearing machine is used to break up the car chip of high wear resistant material (such as bearing iron dust), the rotor is also coated to enhance its wear resistance.
Product features
1. It has the advantages of large torsion, high yield, no manic tone and wear resistance.
2. The volume of iron filings can be greatly reduced by cutting cuttings.
3. Horizontal double roller chip crusher can make the cutting drying, crushing, smelting, crushing, pre-treatment and conveying of chemical fireproof materials easy and easy.
4. It has the advantages of crushing ratio, high production efficiency and small particle size
5. The machine driving device is equipped with safety and electrical protection, which can effectively prevent accidental failure and damage to the equipment.
6. The chip can be continuously feed, or intermittent feed.
7. The use of horizontal chip shredder can be used to facilitate the subsequent treatment of cuttings, effectively reduce the size of chip and save storage space.
considerations
Installation and testing
1. The grinding machine should be fixed on the cement base. If you change the work place frequently, the grinder and motor will be installed on the seat made of Angle iron. If the pulverizer is powered by a diesel engine, the power of the two power should be matched, that is, the power of the diesel engine is slightly larger than the power of the mill, and the two belt grooves are consistent. The outer end of the pulley will be on the same plane.
2. Before starting the machine, it is necessary to check whether the parts of the unit are fastening, whether the elastic belt is suitable and whether the power cord is good. The motor shaft is parallel to the mill shaft.
3. Check whether the hammer is in good condition and whether the aperture of the sieve is suitable or not. Drag the belt by hand to check whether the spindle rotation is flexible, without card, touch and friction.
4. After starting the machine, make the equipment empty for 2 to 3 minutes, check whether the rotor has turned correctly and whether the sound is normal. Work only after the rotation is stable at the rated speed.
5. Pay attention to the operation of the crusher at any time. The feed should be evenly distributed, so as to avoid blocking the boring car and not working long hours. If the vibration, noise, bearing and the body temperature are too high, and the outward jet, should stop the inspection immediately, the troubleshooting can continue to work.
6. The crushed materials should be inspected carefully, and no objects such as stones or metals shall be mixed to avoid damaging the machinery.
7. During the operation of the machine, the operator shall not leave the unit, nor shall it observe the working conditions of the crushing chamber in the operation. The maintenance tools shall not be placed on the machine or filler.
8. The operator should not wear gloves, and when there is a blockage, it is strictly forbidden to plunge the hand into the filling hopper, and stand on the side of the shredder when delivering the material, in case the backlash does not hurt the face.
9. Do not stop immediately after work, and take 2 to 3 minutes at no time, so that the material in the machine can be completely discharged. After the shutdown, should be cleaned, maintenance work.
After 10 is the main wearing parts, hammer, wear both in same direction change the edges and back edges and switch to switch at the same time, the whole set of hammer when changing the hammer will change at the same time, a complete set of hammer rollover cannot use a single hammer. Screen is also vulnerable parts, such as partial screen damage, can be rivet, serious damage needs to change new screen.
11. After 300 hours of operation, clean the bearings and replace the oil. When stopping for a long time, the belt should be unloaded. Safety and operation procedures: operation personnel must be operated by the safety technology education.
Precautions prohibited
1. It is strictly forbidden to peer into the machine from the top of the broken cavity during operation.
2. The electrical equipment shall be connected to the ground, the electric wires shall be insulated and reliable and installed in the steel pipe.
3. It is strictly prohibited to remove and remove materials directly in the broken lumen after feeding.
4. No adjustment, cleaning or inspection shall be performed during the operation of the mill.
