Ore sand making is an indispensable and important part of the construction of infrastructure such as buildings, roads, and railways. As the preferred equipment for ore crushing, jaw crusher plays an irreplaceable role in this process.

Advantages of ore crushing of jaw crusher

Jaw crusher has become the first choice for coarse and medium crushing of ore due to its simple structure, reliable operation and low operating cost. This equipment adopts a zigzag extrusion type crushing method. The eccentric shaft is driven by an electric motor to make the movable jaw move periodically, producing multiple crushing effects such as extrusion and rubbing on the material. For ore raw materials with higher hardness such as iron ore, the jaw crusher performs particularly well. Its crushing chamber design has no dead zone, which significantly improves the feeding capacity and output, and has a large crushing ratio and uniform product particle size.

In the ore crushing process, it is usually divided into three stages: coarse crushing, medium crushing and fine crushing. Jaw crusher can be used for primary crushing (feeding particle size 125mm-750mm) and secondary crushing according to different models. It is the most basic link in the ore crushing process. For all kinds of ores with hardness below 320Mpa, such as iron ore, copper ore, limestone, etc., jaw crushers can efficiently complete the crushing task.

Application of jaw crushers in sand production lines

A complete ore sand production line usually includes feeding, coarse crushing, medium crushing, fine crushing, screening and sand washing. Jaw crushers are often used as primary crushing equipment in conjunction with cone crushers, impact sand making machines and other equipment. For example, in the limestone sand production line, the jaw crusher first performs coarse crushing, and the semi-finished products produced enter the next process for processing. This configuration has low production costs and production efficiency is about 30% higher than other equipment.

Compared with old-fashioned crushing equipment, modern jaw crushers are more advanced in the design of wearing parts, and the jaw plates and side linings are easy to replace, with less wear, which greatly reduces the cost of operation and maintenance. At the same time, the lubrication system is stable and reliable, and the bearings are specially designed to withstand huge impact loads and harsh working environments.

Things to note when purchasing a jaw crusher

Selecting a suitable jaw crusher requires considering many factors: material properties (hardness, water content, silicon content), expected output, discharge particle size requirements, etc. The PE series jaw crusher has a full range of specifications, with a variety of options from production capacity to feed particle size. For users with limited investment budgets, you can consider using mobile jaw crushing equipment, which integrates feeding, crushing, and transportation, reducing infrastructure investment.

Professional ore sand production line configuration can not only improve production efficiency, but also reduce energy consumption and operating costs. It is recommended that users consult professional manufacturers before purchasing, and obtain customized solutions and detailed quotations based on specific production needs to ensure that the investment obtains the best economic benefits.
