Jaw Crawler Mobile Crusher: How to Choose a High-Quality Unit

The jaw crawler mobile crusher, as a primary crushing device, is the most widely used in practical production. With numerous crusher manufacturers offering varying product quality, how can customers select a high-quality mobile jaw crusher?

Trusted Manufacturers and Material Selection
Reliable manufacturers use high-manganese steel, which is hard and wear-resistant, for its strength and extended durability during material crushing. Due to differences in R&D investment, production, and manufacturing costs, prices for jaw crawler mobile crushers vary across manufacturers. Customers should compare quotes from multiple manufacturers to ensure both quality and cost-effectiveness when selecting equipment.

Research and On-Site Evaluation
Before purchasing a jaw crawler mobile crusher, customers should gather information about manufacturers online or through professional publications. If feasible, visit nearby manufacturers for on-site inspections. While assessing the factory’s scale, listen to technical staff’s professional introductions, observe the manufacturing process in the workshop, and inquire about the factory’s industry reputation to choose a credible, high-quality jaw crusher manufacturer.

Key Considerations for Selecting a Jaw Crawler Mobile Crusher
Technical staff fromAnhui SUHMAN Industry outline the following considerations for purchasing a jaw crawler mobile crusher:

1. Check Technical Parameters
   Review the maximum feed size and discharge opening adjustment range in the manufacturer’s technical specifications. These determine if the crusher meets your needs. For example, if a customer requires a maximum feed size of 300mm and an output size of around 45mm, the PE400×600 jaw crusher is suitable, with a maximum feed size of 340mm and a minimum discharge opening of 40mm. Production capacity requirements also vary by customer. It’s recommended to share details about material properties, desired output size, and production capacity with the manufacturer. Anhui SUHMAN Industry’s technical staff will provide an optimal equipment configuration plan and explain the rationale behind the recommendation. Factors like material composition, hardness, and moisture content, often unknown to customers, can also influence equipment selection.
2. Inspect Jaw Plate (Liner) Quality
   The jaw crawler mobile crusher is an advanced, intelligent mobile crushing unit with complex processes involving crushing, feeding, screening, and hydraulic-electrical systems. Some smaller manufacturers offer low prices by using cheap, low-quality components. The jaw plate, a critical component, is often a target for cost-cutting. Anhui SUHMAN Industry uses high-manganese steel alloy jaw plates, which are wear-resistant, long-lasting, and treated with cold processing and water toughening to ensure high hardness and prevent performance degradation during use.
3. Verify Machine Body Material
   Check whether the crusher’s body is made of cast iron or cast steel. For instance, when quoting a PE900×1200 jaw crawler mobile crusher for a customer in Zhejiang, our price was higher than a competitor’s because we use cast steel, while the competitor used cast iron. After inspection, the customer chose our cast steel model for its superior quality.
