;;;;;; VSI crusher major domestic and foreign manufacturers to provide product performance, the gap with foreign-made aircraft major company is a full range of products, mainly in the following aspects.

;;;;;; customer service, especially in the pre-selection service. Most domestic manufacturers are currently developing products based on imitation, often "know how but not the why" processing equipment while different customer cases, the lack of experimental data, often maintaining the status quo. Cause the same machine, the result is not the same as using a different client vertical crusher crushing and screening system customers The flaw also affects the use of sand. For example: When the system is not configured Separators, iron enters the damaged machine, feed particle size when the system exceeds the allowable value, it will cause abnormal operation Zhengzhou Hongxing Machinery Factory when the feed contains too much moisture, the vulnerability will be increased wear. When the feed can not be adjusted, its unevenness will affect machine sand effects, etc. Raymond machine Matters these customers must be noted that the domestic manufacturers tend to not like their foreign counterparts, as described in detail at the time of customer selection, which also damaged the reputation of domestic VSI crusher.

;;;;; product specifications and performance on product specifications and performance, particularly in terms of large-scale machines Henan jaw crusher sand making the foreign large-sized compared with the nation's largest manufacturing specifications. Large-scale differences in the product, is the design level, a comprehensive reflection of the manufacturer capability and performance of the domestic component parts (such as bearings) and other aspects of mill example: the use of the rotor body below the tapered loop fastener positioning. Not the slightest loosening during high speed operation, the nominal size of 600mm diameter of the upper and lower cone concentricity tolerance Hongxing machine designed for 0.02mm, the design requirements for the manufacturer's processing capacity is a test jaw crusher manufacturer

;;;;; life of the machine impact crusher life of the original than the other type of crusher is low, such as jaw crusher, cone and the like. Horizontal and vertical shaft impact surpasses impact use conditions worse jaw broken Thus, a machine component life, is the lifeblood of Sand maker, in conditions similar to the use of part life to make a comparison. Working conditions: Pebbles secondarily crushed and sieved to 5 ~ 30mm feed impeller diameter of 900mm, the speed of 60m / s, very little moisture, motor power 160KW, due to the different materials, different shapes, parts the life of a big gap, but because of expensive imported items, so the performance is still closer than the price of domestic and foreign products and spare parts stone production line manufacturer
;;;; in vertical shaft impact crusher (sand making machine) work, speed is an important factor affecting the quality crusher, vertical shaft impact efficiency and life, but broken the result is not always increase with increasing speed and high speed also increased wear main butt head, seriously affect the life of the crusher. Simulation results show that, 1400-1500r / min and 1600-1750r / min is the main butt head the force balance, to get a smooth operation of the rotor speed range; in addition, in order to fully take into account the crusher broken quality, efficiency and service life, lower The maximum impact force and frequency is essential, therefore both need to consider the rotor structure and optimization of parameters, but also analyze the impact of uniformity of the feed particle size mobile crushing station determining stones and main butt ends of the main impact zone is also very important. impact crusher manufacturers
