Description

The invention relates to the npoNsaii of construction materials.
Brguns are known for grinding ceramic masses containing a bowl, rollers with bandages and a Cl} drive.
The disadvantages of these runners for shredding are the short lifespan due to the uneven and rapid wear of the bowl and bandages on the outer and end surface and also low productivity.
The closest to the proposed technical solution are runners for grinding ceramic masses containing a bowl, the bottom of which form a plate and a grid, rollers with bandages and drive, 2},
However, making cuts in the grid of runners leads to the fact that when the runners work, the angle between the direction of the total force of the roller on the ceramic mass and the longitudinal axis of each slot is not constant and differs from the direct one. This leads to an increase in the path of contact of the mass with the walls of the slits, i.e. to increased, uneven wear of the grille, and therefore to a reduced service life. In addition, inconsistency of the angle causes the appearance of a component of the total force. This component, acting along the slits, squeezes extraneous solid inclusions together with the mass to the edge of the slits, which increases the likelihood of such inclusions at the edges of the slits, as. the area of the largest contact area of inclusions with a fixed wall, jngiouecc clogging of the slots, as well as the movement of the mass at an angle other than direct, ultimately reduces the performance of runners.
A different way of passing the mass through each slot causes a different degree of mass on the exit and contact with the bottom and, Kaik consequence, the production of different strength products,
Within the bottom section, the slots are located relative to, for example, the symmetry axis of the section at a constant angle, i.e. projection of the longitudinal axis of each slot to the radius of the bottom passing through the center of the slot is not constant, depending on the angular position of the radius. This leads to a disorder of the holes on the section and, in particular, to the formation of areas on which only shortened slotted. Ceramic mass, especially hard or containing foreign inclusions, clogs the slots in whole or in part, which reduces the performance of runners and degrades the quality of processing of the ceramic material. .
The purpose of the invention is to increase production and improve the quality of the finished product.
The goal is achieved by the fact that in the runners for grinding the ceramic masses containing the bowl; the bottom of which is formed, plate and lattice, rolls with bandages and drive, the holes in the lattice are located along logarithmic spirals, the poles of which coincide with the center of the chalice, and the angle of each spiral is determined from the relation: ot arctg of LATCH, where dr is the angle of the logarithmic spiral, hail
5 angle of inclination of the conical surface of the tire to the axis of the roller, deg; D is the diameter of the roller, mm. Fig. 1 is a schematic view of the runners, front view; FIG. 2 is a view A of FIG. 1;
The runners contain a bowl 1, the bottom of which is formed by a plate 2 and a lattice 3 with slots 4 made along
logarithmic spirals, t, e. the projection of the longitudinal axis of each slot onto the bottom radius passing through the center of the slot is a constant value. Above the bottom, on axis 5, driving rollers 6 with shrouds 7 are installed, the outer surfaces of which are made conical and facing the bases of the cones towards each other, with the angle of inclination of the conical noBepj. 0andazha to the axis of the rink is-.
5 s within 2-12 °,
Runners work in the following way.
When moving rollers b with conical bandages 7 on the bottom is supplied
On it, the ceramic mass is first processed on slab 2, then pushed through oval-shaped slits 4 lattices 3, made along logarithmic spirals, the ends of which coincide with the center of the bottom, and the angle of each spiral is constant for these runners and ensures that the runners are perpendicular the longitudinal axis of each slot to the direction of movement of the masses. This leads to the constancy of the path of contact of the mass with the walls of all the slits, to an increase in the life of the bottom due to a decrease in its wear. In view of the absence of a cy force of maximal force acting along the slot, the likelihood of foreign solid particles in the slots is stuck. The mass moves perpendicular to the longitudinal axis of the slot, which provides
0 performance increase. The same mass passage through each slot results in the same mass processing fixture. Upon leaving the contact with the grating and, consequently, obtaining the same
strength of products. The ordered arrangement of the slits is also ensured, as well as the presence of all the slits with the same geometrical dimensions. The absence of slots of reduced geometrical dimensions stabilizes the work of runners by productivity, since the blocking capacity of the slots is ceramic-mass, in this case, it is minimized.
