A stone crusher is a machine used to reduce large rocks into smaller pieces. They are commonly used in the construction industry, mining, and quarrying to produce aggregate for use in concrete, asphalt, and other construction materials. GEP ECOTECH provides a full range of Stone Crushers and Screening Machines for the C&D Waste Processing and Aggregate Industries. Stationary and Mobile Versions are available!.
Cone or gyratory crushers reduce material size through a compression method. During their operation, the main shaft drives the mantle in an eccentric motion, altering the distance between it and the liners, thereby achieving the crushing process. Cone crushers have the capability to process various medium to high-hardness rocks and ores, with an excellent reduction ratio. Consequently, they are typically used in the second and third stages of crushing circuits and sometimes even in the fourth or final stages of the crushing process.Cone crushers are known for their powerful performance in handling hard materials, making them widely used in the fine crushing processes of ores and tough aggregates. However, due to their compression-based crushing principle, they produce needle-like shaped output, which is less favored in certain industries. Additionally, cone crushers often face issues of bearing oil leakage, especially in lower-end equipment, as they typically operate under heavy loads. Furthermore, the
The AIShred centrifugal crusher GEV4000, with its small dimensions, is incredibly reliable and has a long service life, is not inferior in performance to its European and American counterparts, and if we talk about price, it completely surpasses them. With good quality, Chinese equipment is much cheaper than European brands. Very simple design and easy operationThe first advantage of this model is a very simple design and ease of operation. Two 55 kW motors are symmetrically opposite each other, which ensures uniform tension, and this allows you to extend the life of the bearings. Many single motor machines have bearings that fail after about 5-7 months, and according to user reviews, GEV 4000 crushers have been running for several years on the same bearings. And even if repairs are needed, due to the simplicity of the design, it can be done on your own, without extra capital investment.Product performance and qualityThe second advantage is productivity and product quality. The productivity of the cycle
A jaw crusher for sale in Poland is a type of crusher that uses jaw compression to break up pieces of material. The jaw crusher is a versatile material crushing machine. It is applied on rocks of any strength, on slags, some metallic materials. Application not possible on viscoelastic materials such as wood, polymers, certain metal alloys. Input fineness reaches 1500 mm. The size of the finished product for small crushers is up to 10 mm. Jaw crushers are available in all crushing classes: coarse, medium and fine. The principle of operation of the GEC jaw crusher is based on the compression of the material by the working surfaces (cheeks), which leads to the occurrence of high compressive and shear stresses that destroy the material. Jaw crushers are best known and widely used for their reliable performance, low operating costs and high product quality. Jaw crusher is a special machine designed for grinding and crushing hard materials, mainly mineral raw materials, suitable for crushing various rocks and
Vertical shaft impact crushers are another type of impact crushers. They reduce the size of materials by rapidly impacting them with a vertically positioned rotor. These machines typically come equipped with two motors to provide the necessary centrifugal force for the rotor. Combined with a unique crushing chamber, they can crush materials into very small sizes while achieving excellent particle shapes. Vertical shaft impact crushers are commonly employed in the final stage of the crushing circuit and find extensive use in aggregate and mining applications. They have garnered the moniker "sand-making machines" due to their pivotal role in the production of manufactured sand.Vertical shaft impact crushers operate by driving the rotors to rotate at high speed through central cantilever shaft. Imbalances in centrifugal forces can lead to abnormal equipment vibrations and damage to the support structures. GEP ECOTECH VSI crushers are multi-purpose crushing equipment that allows for flexible combinations of
Horizontal shaft impact crushers (impact crushers for short) utilize horizontal rotors to strike stones at high speeds, reducing their sizes. The materials produced by impact crushers take on cubic shapes, which are believed to enhance the strength of concrete, making them ideal machines in the aggregate and recycling industry.The greatest challenge faced by impact crushers arises from the high-speed movement of the rotor. Imbalanced forces can result in abnormal vibrations in the equipment. If coupled with poorly manufactured bearings, bearing seats, and machine bodies, it can potentially lead to catastrophic accidents.GEP ECOTECH impact crushers are meticulously designed for safety, stability, and high throughput, offering a choice between two-chamber and three-chamber models. Their bodies are crafted from high-quality raw materials and undergo advanced processing and heat treatment processes to ensure exceptional impact resistance. The expanded feed inlet design enhances the crushing ratio, while the
Jaw crushers, as traditional and continually popular pieces of equipment, find wide applications in the mining, aggregate, and construction industries. They are commonlyused for the primary crushing of materials such as rocks, ores, and discarded concrete. Their operational principle is exceedingly simple, akin to the compression process observed in animal jaws, where they crush materials into smaller sizes. After over a century of development, jaw crushers remain highly favored, owing to their straightforward structures that ensure stable operation and ease of maintenance.As one of the most mature industrial crushing equipment, many companies claim that their equipment boasts top-notch performance. However, in practice, they still encounter numerous issues, such as eccentric shaft bending or fracturing, overheating of bearings, abnormal wear or even breakage of jaw plates, and rod fractures, among others.GEP ECOTECH jaw crushers help businesses establish consistently stable crushing production lines,
