The Tube Mills runs smoothly and safely, and the foundation must extend to a stable, solid base layer. The foundation shall be capable of withstanding the static load and the vibration load generated during the operation of the Tube Mills ; the foundation shall have a sufficiently large chassis and volume, and the base chassis shall be separated from the plant pillar chassis by at least 50 mm apart. The weight of the foundation should be 1.5 to 2 times larger than the weight of the Tube Mills .
Before the installation of the Tube Mills , it is necessary to check whether the basic relationship between the foundation and the buildings and adjacent units is correct. The dimensions of the foundation and the dimensions of the main parts are in accordance with the dimensions specified in the installation drawings. quality.
Foundation If you meet the design requirements, you can clean the foundation surface, with a wind shovel or hand tools to remove the top of the base of the loose floating objects, and marked the installation of the basic center line and elevation. The base surface if the oil residue, should be treated with caustic soda and neutralizer, or the eradication of sufficient depth, so as not to affect the mortar and the bonding between the foundation.
Equipment and basic inspection, ready to start to install the basic bolts, the main bearing chassis and bearing, etc., the main bearing chassis horizontal tolerance of 0.10 / 1000; the relative elevation of the two chassis is generally appropriate to use liquid connector measurement, height difference Should not be large 0.5 mm, and make the feed side higher than the discharge side. The main bearing seat and the chassis should be evenly in contact, local clearance is not greater than 0.1 mm. The contact of the spherical surface of the main bearing pad with the spherical surface of the bearing seat shall be good and the rotation must be flexible. Two with spherical surface should be left around the wedge gap, the oblique depth of 25 to 50 mm, the edge of the gap is 0.2 to 1.5 mm, the contact surface of the contact points now every 50 × 50 mm ² area should not be less than one point The When assembling the main bearing pad and the bearing seat, apply the graphite-coated lubricating oil evenly on the fitted spherical surface. The deviation between the centerline of the two main bearing chassis should be in accordance with the relevant provisions of the specification for the construction and acceptance of metallurgical machinery and equipment installation.
The Tube Mills is mainly composed of cylindrical cylinder, end cap, bearing and transmission large ring gear and other components, the cylinder into the diameter of 25-150mm steel ball or steel bar, known as the grinding medium, the loading capacity for the entire cylinder There is a relatively large volume of 25% -50%. The ends of the cylinder are end caps, and the end caps are connected with the end flanges of the cylinder by means of screws. The middle part of the end caps has holes, which are called hollow journals and hollow journals are supported on the bearings. The cylinder is also fixed with a large gear. In the drive system, the motor through the coupling, reducer and pinion drive large gear wheels and cylinder, slowly rotating.
When the cylinder is rotated, the grinding wheel rises to a certain height with the cylinder wall and then falls or falls down. As the hollow cover is on the end cap, the material is fed from the hollow journal of the left into the cylinder and gradually To the right of the spread of movement, when the material from left to right during the move, the rotating cylinder to the ball to a certain height and fall the material will be broken, and part of the ball in the cylinder into the state of the material has a grinding effect , The entire moving process is also the material crushing process.
A Tube Mills in the right end (discharge end) with a grid plate, lattice board by a number of fan-shaped hole width of 7-20mm, generally 7-8mm is appropriate, the material can be through the grate into the grid plate and the end of the cover Between the space, and then by the board 2, the material up to enhance the material stretched over the plate slide through the tapered block and right to the hollow journal, and then by the hollow journal discharge machine outside.
Another way is the wind nesting Tube Mills with nesting, the material from the feed port into the Tube Mills , with the Tube Mills rotation, grinding Tube Mills within the Tube Mills (steel) on the material impact and grinding, the material from the left side of the Tube Mills Import) gradually move to the right, in the process of moving the material that is broken, grinding process. In the Tube Mills outlet end connected with the duct, in the pipeline system in series with the separator, the election of wind separator, dust collector and fan imports. When the wind system is driven, the Tube Mills body is also in low negative pressure operation. When the grinding of the material with the Tube Mills into a loose rotation, and with the wind from the outlet into the pipeline system, the coarse particles separated by the separator and then into the Tube Mills imports, fine powder separated by the separation of gas, gas By the fan into the atmosphere.
