Structural features of cone crusher in crushing process

        With the development of society, many industries on the ore or other requirements of the fineness of various materials is relatively high, then need to choose a crushing mill equipment. From a professional point of view, if the ore or materials are crushed, crushed to powder, then you need to use a professional mill, such as already very mature cone crusher.

       Cone crusher  to the process of milling production line, large pieces of material broken by the crusher to the required size, the material will be sent to the hopper hopper, and then by the vibration feeder uniform quantitative continuous feeding into the host mill room Grinding, grinding powder after the fan air flow away. By the analysis of the machine classification, with the fineness of the powder with the air through the pipeline into the large cyclone collector, the separation and collection, and then discharged by the powder tube is finished powder. The air is then drawn into the blower from the upper return duct of the large cyclone collector. Cone Crusher The entire air flow system is closed cycle, and is in the positive and negative pressure state circulation flow.

       Compared with the same sand processing production line, the equipment has the advantages of low investment, short payback period, low production cost and high automatization. The conical crusher has low running cost, high crushing rate, energy saving, high output, less pollution and maintenance. Easy to produce the sand in line with national standards for building sand, product size uniformity, grain shape, gradation reasonable.

       Cone crusher all the systems are integrated in a whole framework, both to ensure the integrity of the equipment and leave a modest maintenance and inspection space, is a very convenient feature. Ring hammer crusher long-term operation, important parts will inevitably wear and damage, there will be decreased power equipment, energy consumption increased, because some of the technical maintenance equipment to maintain the superiority of the equipment is very necessary, the new equipment Must be carried out in accordance with the instructions for empty test operation, to regularly check the bearing wear is uniform, there are problems in a timely manner to deal with and resolve. 

       Cone crusher main work accessories is the rotor, is by the spindle, disc, pin and hammer composition, the motor drives the rotor in the crushing chamber high-speed rotation: 

        1. When the crusher running 60 hours, the lubricating oil on the bearing time;

        2. Must regularly check the fasteners are reliable, if necessary to ring hammer crusher ring hammer to be replaced;

        3. Replace the ring hammer, you should first open the rear of the body, and then move the rotor disk, so that the hammer shaft in the middle of the body and the rear between the body, can be extracted from the chuck. Remove the hammer axis of the mountain pin, and finally remove the hammer shaft, the replacement;

      In ensuring the size of the premise of the product, as far as possible to reduce the rotor speed of rotation method is a good way to reduce the hammer wear. In addition, a reasonable line speed with the appropriate number of hammer with which to ensure that the material in the impact zone to have enough wedge depth, otherwise, will lead to plate hammer should not have some wear. Improve the utilization rate of hammer hammer to reduce the plate hammer replacement time: the use of solid hammer hammer, the replacement time and its structure and style are closely related. Multi-cavity cone crusher hammer type can achieve high utilization rate of plate hammer (about 45% -50%), shorter replacement time goal.

      Cone crusher mainly uses the following two strategies: (1) symmetrical structure, simple tightening; (2) large flip, large access door. Shortened downtime maintenance time. These two measures not only improve the metal utilization of the hammer, conical crusher service life has also increased. In addition to ensure quick and easy replacement of plate hammer, plate hammer material is usually high manganese steel, which is broken medium hardness of the material is applicable, broken hard materials, such as basalt, diabase, biotite, granite, etc. , Plate hammer must have good corrosion resistance, while conical crusher must also have a high wear resistance. Domestic and foreign data show that chrome molybdenum alloy cast steel, high-chromium white cast iron and other materials can be used as an ideal material hard broken hammer material.
