Crushed stone machinery and equipment in the gravel production line generally use: jaw stone crusher, impact crusher (when the material hardness is small), cone crusher (when the material hardness is too strong or corrosive) Sand-making machines (impact crushers) sometimes use fine-grain crushers, hammer crushers, etc. The crushing machinery equipment mainly depends on its wear-resistant parts and stone materials. Impacts and blows have resulted in very severe wear of wear-resistant parts such as hammers, jaws, counter hammers, and rolling rakes, which have greatly affected the economic interests of customers in gravel and gravel plants.

So how to choose wear parts and extend the trial life of wear parts? China's famous casting wear-resistant materials company Zhengzhou Ding Shing Engineering Technology Co., Ltd. Technical Department gives the following suggestions.

1. Pay attention to the daily operation skills The main parts of the impact crusher are the rotor and the plate hammer. The wear parts of the sand making machine (vertical shaft impact sand making machine) are mainly the plate hammer, alloy cutter head and lining plate on the impeller. The rotor, jaw plate and side guard plate are the main wear parts of the jaw crusher. The hammer of the crusher is the main wearing part of the hammer crusher. The main wearing parts of the cone crusher are the rolling crusher. Walls and broken walls. Grasping the daily work skills of the correct gravel machinery can effectively reduce the wear loss efficiency and prolong the service life of wear parts.

For example, when a rake type gravel works, the bolts of the sampan plate vibrate and the nut is loosened, which makes the sampan plate wear more severe and generates a loud noise, which can cause the jaw plate to fall off or be discounted. Therefore, in order to extend the service life of the jaw plate, nuts and bolts must be inspected frequently to prevent increased wear, looseness, and breakage of the jaw plate, thereby extending the service life of the jaw plate, reducing costs, and improving work efficiency. For another example, during the use of a hammer type hammer crusher, the hammerhead must be replaced in time, which can greatly increase the service life of the hammerhead.

This point, the gravel machinery factory should take the responsibility to provide customers with comprehensive operation training and master the skills of prolonging the service life of the extremely wear-resistant parts of the gravel machinery and equipment. The thoughtful after-sales service of Zhengzhou Dingsheng Company has already experienced it. .

2. Various types of hammerheads and different rock crusher machines are "seat by number."

The basic principle for selecting a hammerhead is that the small hammerhead is made of a high-chromium composite and the heavy headed high-manganese steel is used. Corrosive materials are not suitable for forging hammerheads. The service life of the hammerhead in each area of ​​the cement plant and the crushing plant is also not the same. The hammer with the longest lifespan on the market is the hammerhead of the tungsten-titanium alloy carbide block, of course, also requires advanced casting technology and precision. Chemical analysis equipment and other hardware devices.

Different materials have different physical and chemical properties, and the wear of wear parts varies greatly. For example, if the quartz rock crusher uses a counterattack crusher, it is prone to the occurrence of plate hammer fracture. At this time, the conical crusher should be selected and it will not cause excessive wear on the wear-resistant workpiece rolling wall.

3, choose the casting strength of the same manufacturer of wear-resistant parts of the same specifications, in the same cement plant, rock use, life is different, because the quality is different. Because each manufacturer's casting process, chemical matching, and the corresponding degree of hardware equipment are different, the quality difference is also greater. When choosing a manufacturer of castings and wear-resistant parts, it is imperative to inspect the factory, including the management of the factory, the number of engineers, the technical level of the equipment, etc., as well as the feedback from the customers of the stone crushing plant using its products.
