How to use the jaw crusher: 3. In the production process of using the jaw crusher, it is advisable to set the control feed rate device and pre-screening and inspection screening, which can make the product granularity uniform, reduce the crushing and improve the quality of the crushed product.
1. Jaw crusher is widely used in metallurgy, building materials, chemical industry, coal and other industrial sectors. It is suitable for coarse, medium and fine crushing of various materials with Mohs hardness below 7 grade. When used for fine crushing, it should be finely crushed. Jaw crusher.
2. Suitable materials for jaw crusher: pyrite ore, phosphate rock, barite, celestite, calcium carbide, coke, limestone, etc., should not be used for the crushing of ore.
4. When the jaw crusher is used to crush medium hardness (Pu's hardness coefficient is about 4) and brittle rock, the lining plate has a rib shape, and the angle between the ribs is 90° to 100°;
5. When the crushing is hard and quite hard (Pu's hardness coefficient is 5-10), the lining plate is wavy ribbed shape;
6. When the material is very hard and very hard (Pu's hardness coefficient is 10~18), the lining should be a wide rib. The ratio of the ridge width t and the ridge height h of the lining plate is t/h≈ 2 to 3.
7. When selecting the type of crusher, first select according to the maximum feed size. If the production volume of a coarse crushed jaw crusher can meet the needs, you should choose to use the jaw crusher. Usually, when the production volume is less than 550t/h, the jaw crusher tends to be used; in the middle and fine crushing, the jaw crusher is also selected when the production volume is small.
