This paper introduces an improved method of gap adjustment of hammer crusher

Hammer crusher It is the main crushing equipment in many mines. In the production process, in order to ensure the particle size and production efficiency of mineral powder, the gap between vertical grate plate and hammer head must be adjusted several times in each shift. The following is a detailed analysis of the defects of the original adjustment method, and puts forward effective improvement methods.

 Hammer crusher

The original adjustment structure is shown in Figure 1. When adjusting, the box door 4 must be opened, and then an adjusting pad should be added between the adjusting rod 1 and the base 2. Before adjusting, the mineral powder covered on the adjusting rod 1 must be adjusted. This adjustment method is not only labor-intensive, but also time-consuming, which is not conducive to improving the production efficiency of the crusher.

In order to adjust the difficult problems, the structure of the adjusting parts can be improved. The improved form is shown in Fig. 2, that is, a steel plate is welded at the tail of the adjusting rod 1 as the top plate 2, the box door panel 3 is shortened, and a base plate 5 is added under it to install the adjusting screw 4. The base plate 5 is installed on the box 6 with bolts, and the screw rod 4 is the screw pair of tr50 x 8.

Through the improvement, the gap between the vertical grate plate and the hammer head is adjusted outside the box. When adjusting each time, it is only necessary to turn the adjusting screw 4 to the right outside the box body to reduce the gap between the vertical grate plate and the hammer head; if the clearance between the vertical grate plate and the hammer head is adjusted too small, the adjusting screw 4 can be transferred out of the box by left rotation. After use, the clearance between the vertical grate plate and the hammer head can be adjusted without stopping the machine, so as to achieve the purpose of adjustment at any time. The operator does not have to open the box door in each adjustment, and does not need to clean the powder ore between the vertical grate plate and the box door, which greatly reduces the labor intensity of the operator, so that the production efficiency of the hammer crusher has been significantly improved.
