Background

The ring hammer crusher is a conventional crushing machine and consists of a ring hammer rotor assembly, a grate assembly, a shell, a driving assembly and the like. The motor drives the ring hammer rotor to rotate at high speed in the crushing cavity. The crushed materials are conveyed into the machine body from the upper feeding port and are crushed under the impact of the high-speed rotary motion ring hammer, the mutual collision among the materials and the like. The grates are arranged below the ring hammer rotor, crushed material particles smaller than the size of gaps between the grates are discharged through the gaps between the grates, the material particles larger than the size of the gaps between the grates are continuously beaten by the ring hammer, and finally the material particles are discharged outside the machine body through the gaps between the grates.

For the production of clinker and sandstone aggregate, because the requirements of the size of the crushed grain diameter of the clinker and the sandstone aggregate are different, crushers with different specifications are required to be adopted, the crushers with two specifications are required to be prepared for factories producing clinker and sandstone aggregate, the production cost of the factories is increased undoubtedly, therefore, the crushers for producing clinker can be modified to meet the production requirements of the sandstone aggregate, namely, the grates of the crushers for producing clinker are modified, and the crusher grates capable of meeting the production requirements of the sandstone aggregate need to be designed.

FIG. 1 is a schematic view of a crusher grate according to the present invention;

fig. 2 is a sectional view a-a of fig. 1.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1-2, the crusher grate comprises a bracket 1, a grate frame 2, grate plates 3 and stop blocks 4, wherein the grate frame 2 is fixedly installed on the bracket 1 through set screws 5, the grate plates 3 are arc-shaped, the upper end surfaces 31 of the grate plates 3 are wave-toothed arc-shaped surfaces, the lower end surfaces 32 of the grate plates 3 are smooth arc-shaped surfaces, arc-shaped sliding grooves are formed in the grate frame 2, the lower end surfaces of the grate plates 3 face the direction of the grate frame and are installed in the arc-shaped sliding grooves of the grate frame, the stop blocks 4 are used for supporting the grate plates 3 to be fixed on the grate frame 2, grate slits 7 of the grate plates 3 are in a trapezoidal shape with the upper part wide and the lower part narrow, the width of the upper ends 71 of the grate slits 7 is 2-5 cm, and the width of the lower ends 72 of the grate slits 7 is 1-4 cm.

In the embodiment, the grate seam is designed into a trapezoid shape with a wide upper part and a narrow lower part, so that broken gravel aggregate can be discharged more smoothly; the width of the grate seam can be designed according to the particle size required by the product, so that the sandstone aggregate with large particle size can be prevented from passing through, and the qualified particle size of the product is ensured; the utility model discloses a grate can be installed and be used for producing the grit aggregate on the breaker of production grog, and the width of grate seam can satisfy the particle diameter production requirement of grit aggregate, the effectual utilization ratio that promotes the breaker has further reduced the manufacturing cost of mill.
