In crushing operations in industries such as mining, building materials, and metallurgy, spring cone crushers are highly favored due to their reliable structure and high production efficiency. Among them, spring cone crushers equipped with a 55 kW motor typically correspond to equipment specifications of Φ900, such as models PYB900, PYZ900, and PYD900.

This type of crusher is suitable for medium and fine crushing of materials with medium to high hardness, such as iron ore, limestone, granite, etc. Its crushing cone has a large end diameter of 900mm, with a maximum feed size of up to 115mm. The discharge opening width can be adjusted between 3 and 50mm according to demand, and the processing capacity is generally between 15 and 90 tons per hour. The specific output is affected by the material properties and the crushing chamber shape.

The PYB model features a standard chamber, suitable for medium crushing; the PYZ and PYD models are designed for medium-fine and fine crushing chambers, respectively, and are ideal for applications where a finer particle size is required. The overall structure of the equipment is compact, weighing approximately 11 tons, and operates smoothly. Equipped with a spring safety system, it effectively prevents damage to the machine body from metal foreign objects.

This configuration is widely used in small and medium-sized sand and gravel production lines, combining economy and practicality, making it an ideal choice for crushing processes in many enterprises.
