Jaw crusher, commonly known as jaw crusher, also known as "Tiger's Mouth", is the main equipment in the stone production line. It is generally used for coarse and medium crushing of hard or medium hard stones. It is widely used in industries such as water conservancy and chemical industry.
High-quality and low-priced jaw crushers are the equipment that almost all users are looking for. In daily production, the quality of jaw crusher is directly related to production efficiency, production capacity, finished material effect, enterprise cost and economic benefits, etc. The following seven points are closely related to the quality, production efficiency and economic benefits of jaw crushers.
1. Rack design—integral casting vs split assembly
Due to the limitation of casting technology, the integral casting frame will form a large number of tiny pores or inclusions in the casting process, which reduces the overall performance of the frame. Relatively speaking, the split-assembly rack-type jaw crusher is lighter, stronger and more durable.
2. Jaw plate design—integral vs three-stage
Large-scale jaw crushers usually use three-stage combined jaw plates. In addition to being more convenient for assembly, installation and disassembly, the main thing is that the middle piece is small and the two ends are the same size. Switch the position of the board and continue to use it to save costs.
3. Bearing seat fixing method - welding vs bolts
Some jaw crusher bearing seats are welded on the frame, and some bearing seats adopt integral cast steel structure, which is connected with the frame by bolts, which ensures full cooperation with the crushing frame and greatly enhances the radial direction of the bearing seat. strength. The difference in the manufacturing process makes the service life of the two also different.
In addition, some jaw crushers have installed heavy-duty guard plates on their bearing seats to avoid accidental damage to the bearing seats.
4. Adjustment method - hydraulic wedge adjustment vs gasket adjustment
The adjustment of the hydraulic wedge can achieve stepless adjustment, which is convenient to adjust, saves time, does not need to stop, is simpler, more convenient and faster, has advanced technical level and high efficiency. Of course, its price is also high.
5. Crushing cavity shape - half V shape vs symmetrical V shape
The V-shaped cavity structure makes the actual width of the feed opening consistent with the nominal width of the feed opening, and it is easier to discharge materials, relatively less prone to material blocking, less prone to material jumping, deeper crushing chamber, no dead zone, and higher crushing efficiency. high.
6. Lubrication method - manual lubrication vs centralized hydraulic lubrication
Some old-fashioned jaw crushers use manual lubrication, and the operator uses an oil pot or an oil gun to add oil to the oil holes, nozzles and cups of the lubrication point. This method is time-consuming and labor-intensive. In comparison, centralized hydraulic lubrication has improved a lot in terms of operability and technology.
Seven, guard plate shape - ordinary guard plate vs toothed guard plate
Because the guard plate has more contact with the material, in order to prolong the service life, the material of the guard plate is generally made of wear-resistant high manganese steel. Compared with ordinary guards, toothed guards can increase the effective length of the jaw plate and increase the output.
In addition to the above mentioned, the production material, processing technology and processing technology level of the jaw crusher parts will also affect the quality and production efficiency of the equipment. "Good products are not cheap, and cheap products are not good" has some truths, but it is not entirely true. Bellian Machine hereby warmly reminds you that you should not pay too much attention to the price when purchasing equipment. You must understand the quality, compare multiple companies, and choose regular products. Products produced by the manufacturer, so as not to affect the subsequent normal production.
As a leading enterprise in the mining machinery industry, Bellian Machinery has been focusing on mining machinery for 40 years. Its R&D and manufacturing of multi-standard and multi-series jaw crushers, such as CJ series European jaw crushers, HD German impact crushers, PE series jaw crushers, PEX series jaw crushers, etc., rely on high quality, low price and considerate service, and have been well received in the domestic and international markets, and have been unanimously recognized by users.
The year 2018 has arrived. Facing the booming infrastructure construction in China and the huge cake of the 100-billion-level market, have you selected cost-effective equipment?
