Dust-proof device: In order to prevent dust from entering the friction surface of the bowl-shaped bearing bush of the counter-type sand making machine and the size of the silver ball, the counter-type sand making machine adopts a water-proof dust-proof device. An annular groove is arranged on the bowl-shaped bearing frame of the counter-type sand making machine, the circulating water is passed through the groove, the cone is welded on the lower part of the moving cone body; the baffle (dust ring) is used, and the counter-type sand making machine is working. The dustproof baffle is inserted into the circulating water to keep the dust out. The dust entering the water is washed away by the cycle.
Feeding device: Uniform feeding is important for improving the output of the counter-type sand making machine, ensuring the uniformity of the particle size of the counter-type sand making machine and reducing the wear and damage of the counter-type sand making machine. The feeding device of the counter-type sand making machine mainly consists of a feeding funnel, a feeding box, a curved steel plate and a distribution plate. The function of the ore feeding device is to ensure that the ore fed into the counter-type sand making machine is smoothly and evenly distributed in the crushing chamber around the moving cone. To this end, the position of the counter blasting machine to the hopper, the height of the inlet to the distribution plate, and the size of the curved steel plate from the edge of the inlet should be selected.
