Durable Double Roller Crusher 2PGQ750x500 Coal Stone Machine for Coal Crushing

The Durable Double Roller Crusher 2PGQ750x500 uses two counter-rotating rolls to grip and fracture brittle material with minimal fines generation. Because crushing is achieved by compression between the rolls rather than high-speed impact, the machine produces a uniform product with a low proportion of over-crushed powder, an important advantage for coal, coke and salt. The roll surfaces are protected by wear-resistant linings that can be resurfaced or exchanged, and the spring-loaded roll bearing allows the gap to open automatically when uncrushable material passes through, protecting the machine from damage.

• Low Over-Crushing: Compression crushing between the rolls limits powder generation, preserving the value of coal, coke and other sized products.
• Automatic Overload Protection: Spring-loaded bearings let the movable roll retract when hard foreign objects enter, allowing them to pass and preventing serious damage.
• Wear-Resistant Roll Linings: Interchangeable linings resist abrasion and can be replaced individually, keeping the machine in service far longer than an unprotected roll.
• Adjustable Product Size: The gap between rolls is easily set to control discharge size, so one machine can meet different product specifications without major modification.
• Compact Low-Profile Design: Its low headroom and small footprint suit mobile and underground installations where vertical space is limited.
• Even Wear and Stable Running: Balanced rolls and heavy bearings run smoothly with low vibration, giving consistent performance and a long service life.

This roll crusher is a standard machine in coal preparation plants, coking plants and power stations, and it also serves the salt, fertilizer, ceramic, glass and chemical industries. It is applied to medium and fine crushing of coal, coke, limestone, gypsum, bauxite and other brittle or medium-hard materials where a controlled, low-fines product is required.

Rollers are shipped with protective covers and the bearing housings sealed against moisture. Each unit is supplied with a full set of linings, a spare spring set and a commissioning manual. The crusher is assembled and test-run at the factory. A twelve-month warranty and a responsive spare-part supply cover the drive, rolls and bearings, helping you avoid unplanned downtime.
