Taking the theoretical vertical line as the center, the motor drives the eccentric main shaft through a belt pulley and a gear assembly, rotating in a fixed outer cone. The movable internal cone is rotated at the same time with the eccentric main shaft, the running track of the inner cone is rotated swing in the crusher. When the movable inner cone is close to the fixed outer cone, the minerals between them will be crushed. When the movable inner cone leaves the  fixed outer cone, the crushed materials will be discharged by its own weight. When the unbroken objects are dropped into the crushing chamber, the movable inner cone will be decline under the bottom single cylinder hydraulic controlled, So as to play the role of adjusting the discharge port， repeatedly lifting and removing the clogged ores.

1. The PYY series single cylinder hydraulic cone crusher is a cone crusher with advanced techniques in the world, not only has high reliability but high efficiency in crushing, low-cost operation, and good particle shapes of the products.

2. It has several crushing chamber models to select, by selecting the appropriate crushing chamber and eccentric distance, it can maximum satisfy the clients of the product demands.            

3. It takes hydraulic adjust of the discharge of minerals, being able to adjust in a timely and easy way the discharge of minerals, so that the crusher works under the condition of filling material , reducing the consumption of wearing parts and operating costs;

4. By taking advantage of the advanced hydraulic technique, it can effectively perform overload protection, which simplifies the crusher structure, reducing the weight. All repair and maintenance can be accomplished from the top of crusher, making it easy for repair.

Widely used in mining and sand and gravel industry, suitable for crushing various materials with medium hardness. Such as iron ore, non-ferrous metal ore, granite, limestone, quartzite, sandstone, gravel and so on various kinds of ores and rocks.
