The Three Methods of Distinguishing the Quality of Crusher Wear Parts

How do we choose crusher wear parts?

We often use crusher in metallurgy, construction, aggregate and mining plants and other industries. Surely, we all know that the crusher wear parts play a crucial role in the crushing process. High quality wear parts help to cut costs and increase production. So how can we distinguish the quality of crusher wear parts? We can start from three aspects as belo

Appearance quality:

  • We can check the smoothness of the surface, the cracks on the products, the dimension, the shape and weight of each product. Besides, each product will be strictly inspected before shipping to ensure the products are in good condition to use. We provides Dimension Inspection report for your review.

Internal quality:

  • We usually examine the grain size of the crusher wear parts, chemical components, Metallographic structure, pores, etc.. Our comany also offers reports for High Chromium Chemical Components and Manganese Steel Metallographic test for your reference. The report below is for material of Hi-chromium. We made the product of High-Chromium– it has good property in hardness, wear-resistance, heat- resistance are higher, but it are brittle too. Generally, we use the 26% HiCr to cast blow bars for Vertical Shaft Impactors, Hammers, Cheek Plate, Wear Bars etc. .

Performance Quality:

  • Performance quality usually refers to replacement parts for crusher how long they last in working, and how effectively they can crush under difference circumstances (including wear resistance, heat resistance, corrosion resistance, impact resistance etc.). Moreover,there are many factors affecting the quality of crusher spare parts: the first is 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. And the second is the 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.). And the last is the quality of the raw materials. In fact, the casting quality depends on the raw materials you use as well, including Mn material, refractory materials, fuel, molding sand, sand binder etc. If the raw materials do not meet the standards when we cast it, 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. We Chengdu Gubt Industry produces various crusher liners for crushing machineries.
