METSO HP5 cone crusher is foreign imported equipment introduced by HAIKUANG company in 2010. Its features are as follows: Large crushing ratio, short crushing process, saving material space and high productivity The function of changing from coarse cavity to superfine cavity is only to change the cone crusher plates and rotate speed By changing the cone crusher plates and adjusting the rotating speed, it can adapt to the transformation from medium crushing to artificial sand making or ultra-fine crushing.  However, the fixed and moving cone liners are vulnerable parts, with large annual loss and high price, the supply cycle is long, which affects the normal production. Our foundry has many years of experience in making crusher liners , so it is decided to make the liners of the equipment domestically by us. Selection of cone crusher liner material and analysis of the chemical composition Crusher liner is an important part of the cone crusher, and also the main wear par...

Our customer had used HP400 cone crusher to crush stone， our foundry supplies cone crusher replacement parts for this customer. In the process of use, due to the extremely unstable nature of the ore and the influence of the season, the water content of the ore changes greatly, which has adversely affected the normal operation of the crusher. Problems The fixed cone is the main component of the HP 400 cone crusher. It is a ring structure with an inner diameter of l 156 mm, an outer diameter of l 556 mm, a height of 840 mm, and a thickness of 220 mm. There are two sets of dressing plants, which are called A and B fixed cones. In use until March 2013, two sets of fixed cones had severe cracks, the cracks were located on the inner ring surface, and the auxiliary ring stabilizing nail holes were used as nodes, which were evenly distributed and cracked longitudinally. There are 8 cracks in the fixed cone of piece A, 2 of which are larger and penetrate through the thickness direction, ...

Our customer, Anshan Lean Hematite Ore, has 3 kinds of cone crushers (PYD 2200 spring cone crusher, H8800 cone crusher, and HP800 cone crusher). Qiming Machinery not only supplies its cone crusher wear parts , and also supplies analysis service. The main is that compare the H8800 cone crusher with HP800 cone crusher. Ore properties In the process of beneficiation of lean hematite in Anshan area, the ore treated belongs to the typical Anshan type iron ore which is poor in iron, high in silicon and low in sulfur and phosphorus. The mineral composition and structure are relatively simple. The iron minerals in the ore are mainly hematite, limonite, and pseudohematite. The gangue is mainly quartz, with a small number of silicate minerals. The particle size of the ore is fine, the inlaying particle size of the iron ore is between 40-65 μ m, and the hardness coefficient of the ore is 12-18. Equipment structure comparison 1.Different adjustment modes of ore discharge outlet. Sandv...

Our customer had imported 2 sets H-8000i cone crushers and 2 sets H-8800 cone crushers. After long time use, the advantages and disadvantages had shown. Advantages of H-type hydraulic cone crusher The biggest advantage of an H-type hydraulic cone crusher is its large capacity and good crushing effect. The effective grain content of H-8000i hydraulic cone crusher and h-8800 hydraulic cone crusher in unit time is respectively 180 t / h and 115 T / h higher than that of Symons cone crusher, and the fine crushing is respectively 154 T / h and 355 T / h higher. The four cone crushers are put into use, which greatly improves the production capacity of the system. The lifting of the moving cone is carried out through the hydraulic system, which greatly reduces the labor intensity and time of the adjustment of the ore discharge opening. The original adjustment of ore discharge opening of Symons cone crusher is to adjust the ore discharge opening through the lifting of the fixed cone...

Our customer had imported the Sandvik CH870 cone crusher.  Since entering the factory in 2011, it has been installed in two fine crushing production lines of Φ300 / Φ60 and Φ60 / Φ15. With the gradual improvement of production capacity, the wear and tear of body parts increased, and more and more failures occurred. Due to the nature of the minerals in the process of use, the on-site environment is relatively poor, resulting in lubricating oil, which seriously affects the normal operation and service life of the lubrication system. This results in accelerated wear of the running parts, frequent equipment maintenance, which affects the full performance of the equipment, and brings a significant increase in maintenance costs. Therefore, it is urgent to reform the positive pressure dustproof system. Cause of system pollution The main contaminated lubricant is the CH870 fine crusher. It is installed at the end of the 4 # tape. Due to the piston effect of the tape corridor, the dus...
