Cone crushers are essential mining crushing equipment that have evolved over the years into a wide range of models, including hydraulic cone crushers and spring cone crushers. With the continuous advancement in iron tailings utilization technology and related processing equipment, the application of iron tailings in the construction materials industry has grown significantly. These tailings are now widely used across various sectors of building material production, offering energy savings and cost reduction benefits.
The reprocessing of tailings helps reduce the costs associated with dam construction and maintenance, as well as cutting down on expenses related to grinding, mining, and transportation. It also minimizes investment in new equipment and process development. As a result, there is increasing interest in diversifying tailings treatment methods. The equipment used must be versatile and capable of handling a variety of materials. The new cone crusher developed by Zhengzhou Yifan Machinery Co., Ltd. offers a reliable structure, high efficiency, easy adjustment, and economical operation. Its spring safety system acts as an overload protection device, allowing foreign metal objects to pass through the crushing chamber without damaging the machine. The unit is sealed with dry oil or water to ensure proper separation between stone dust and lubricating oil, making it highly reliable.
The type of crushing chamber is selected based on the ore being processed. The standard type is ideal for medium crushing, the medium type is suitable for fine crushing, and the short type is designed for coarse crushing, enabling it to handle most tailings processing tasks effectively.
Cone crushers are primarily designed for crushing medium to hard ores and have proven effective in processing tailings. After processing, the output can be divided into crushed stones and sand, both of which are widely used in various industries. Given the massive amount of tailings generated annually—over 100 million tons in China alone—efficient processing solutions like cone crushers are becoming increasingly important. These machines, along with other mining equipment such as mills and sand-making systems, play a crucial role in recycling valuable minerals and producing aggregates for construction purposes.

Double-Column Universal Material Tensile Test Machine
A Universal Tensile Testing Machine, also known as a universal testing machine (UTM) or a materials testing machine, is a versatile instrument used to determine the mechanical properties of materials. It is commonly used in industries such as manufacturing, construction, and research laboratories.
The machine applies tension, compression, bending, and shear forces to test the strength, elasticity, and durability of various materials such as metals, plastics, textiles, rubber, ceramics, and composites. It can measure parameters such as tensile strength, yield strength, elongation, modulus of elasticity, and fracture toughness.
A typical UTM consists of a load frame, grips or fixtures to hold the specimen, a load cell or force transducer to measure the applied force, and a displacement transducer to measure the deformation or displacement of the specimen. The machine is controlled by a computer or a control unit that allows the user to set the testing parameters and record the test data.
During a tensile test, the specimen is placed between the grips and a controlled force is applied until the specimen fractures. The machine continuously measures the applied force and the corresponding deformation or displacement of the specimen. The data is then plotted on a stress-strain curve, which provides valuable information about the material's behavior under tension.
Universal Tensile Testing Machines are crucial in quality control and material selection processes. They help manufacturers ensure that their products meet industry standards and customer requirements. They also aid researchers in developing new materials and improving existing ones.
