Crushers are widely used in metallurgy,construction, mining and other industries, and wear parts play a crucial role in the crushing process. High quality wear parts help to cut costs and increase production. How can we distinguish the quality of crusher wear parts? We can start from three aspects as below,
- Appearance quality: we can check the smoothness of the surface of the spare crusher parts, the cracks on the products, the dimension, shape and weight of each product. Each product will be strictly inspected before shipping to ensure the products are in good condition to use. Gubt provides Dimension Inspection report for your review.
- Internal quality: usually we examine the grain size of the crusher wear parts, chemical components, Metallographic structure, pores, etc.. Gubt offers reports for Chemical Components and Mn Steel Metallographic test for your reference. The report below is for material Hi-chromium. the products made of Hi-Chrome, their hardness, wear-resistance, heat- resistance are higher, but the products can be broken easily. Generally, the wear parts for Vertical Shaft Impactors are made of 26%Cr, such as: Hammers, Cheek Plate, Wear Bars etc. .
- Performance Quality: generally, performance quality refers to wear parts how long they last, and how effectively they can crush under difference circumstances (including wear resistance, heat resistance, corrosion resistance, impact resistance etc.). There are many factors affecting the quality of spare parts. 1. The design of the products. When designing, the casting geometry and dimension is not only determined by the working condition and the metal materials, but we also need consider from the perspective of casting alloy and casting process characteristics to decrease the rate of scrap. 2. Casting process. Castings’ structure, weight, dimension etc. are the crucial factors for castings. With these criteria, the best casting solution will be optimized (the molds, core-making method, cold iron, risers, pouring systems etc.). 3. The quality of the raw materials. The casting quality depends on the raw materials you use, including Mn material, refractory materials, fuel, molding sand, sand binder etc. If the raw materials of the castings do not meet the standards, the castings will have defects such as pores, slag inclusions, sand sticking, etc., which will affect the appearance quality and internal texture of the products, or the products will be scrapped.
Here we only briefly introduced some factors that affect the quality of the product. Hope it will be useful for you. If there is any question about us, please feel free to email us for more information. Email: email@example.com
