The moisture content of materials subject to little effect, moisture content up to 8%. 5. More suitable for crushing medium-hard, extra-hard materials. 6. Excellent product shape, a cube, flakiness content is very low. 7. impeller from lining wear small, easy maintenance. 8. work noise below 75 db (db level). Cone crusher routine maintenance 1, to full production, there would be too coarse granularity. 2, the production line of broken than allocated to a reasonable Hebei ring hammer crusher, so as to maximize the efficiency of the crusher. 3, there must be in addition to the iron equipment hammer crusher machinery, to prevent the crushing chamber through the iron, if iron is too frequent, it may cause broken shaft accident. 4, the spring pressure is not too tight Henan hammer crusher, too much pressure will be broken shaft accident occurred hammer crusher, the pressure is too small springs frequently beating, impact crusher work, and coarse granularity.
