Limestone Jaw Rock Crusher with Adjustable Tongs Features Outlet Size 20-50mm

Based on many years' experience and technology development, Dingbo jaw crusher series are of 8 different types, which can meet most of the crushing requirements in primary and secondary crushing. Flexible discharge opening setting of jaw crusher allows perfect match with relative equipments. With larger feed openings and bigger crushing strokes, the Dingbo Primary Jaw Crusher are suitable for crushing big size lumps in large quantity. The stone jaw crushers are especially recommended for primary and concrete recycling, river stones, tough ores, for a very long life. From the welded steel base to the rugged eccentric shaft, the hydraulic Jaw Crusher are built with brute strength with quality bearings.

Characteristics of Jaw Crusher:

1. Optimized crushing cavity greatly improves feeding and crushing efficiency, saving energy by 15% -30%;
2. The larger heavy eccentric shaft, high manganese steel jaw plate and movable jaw assembly brings higher carrying capacity and stability.
3. Adopt the world's advanced manufacturing technology, digital analysis of components operating and precise internal structural greatly extend the lifespan of device.
4. The unique design of centralized lubrication system is more efficient for components lubrication but requires less maintenance.
5. Gasketed discharge adjustment of device permits larger adjustable range, which increases the flexibility of the device to meet the demand of customer in processing.
6. The device is in line with the national environmental standards, low noise with dust removal equipment, which is in full compliance with environmental requirements.

Working Principle:
This jaw crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.
