Brief introduction

Product Introduction:

Jaw crushers serve as the primary crushing equipment for various minerals and rocks. Specifically, they handle a broad range of ores and rocks with a compressive strength of up to 320 MPa, converting them into medium-sized particles in a single operation. In practice, industries often pair jaw crushers with cone crushers, impact crushers, and sand making machines to form complete sand and gravel production lines. Thanks to their versatility, jaw crushers find wide use across multiple sectors, including mining, metallurgy, chemical engineering, building materials, power generation, water conservancy, and transportation.

Working Principle：

Jaw crushers mainly include a frame, an eccentric shaft, a large pulley, a flywheel, side guards, a toggle plate, a toggle plate seat, a gap-adjusting screw, a reset spring, a fixed jaw plate, and a movable jaw plate. Jaw crushers use a curved compression crushing method. During operation, the motor drives the belt and pulley. These then drive the eccentric shaft. The eccentric shaft moves the movable jaw up and down. When the movable jaw rises, the angle between the toggle plate and the movable jaw widens. This pushes the movable jaw plate toward the fixed jaw plate. The material is crushed repeatedly between the two jaw plates. It is pressed, ground, and rolled. When the movable jaw descends, the angle between the toggle plate and the movable jaw narrows. The pull rod and spring act on the movable jaw plate. The movable jaw plate moves away from the fixed jaw plate. The crushed material falls freely. It goes through the outlet at the bottom of the crushing chamber. Gravity causes this fall. The motor rotates continuously. The movable jaw performs periodic crushing and discharging. This enables mass production.

Product selling points：

①Able to withstand strong impacts.

First, split welding cast steel frames feature a simple structure and strong impact resistance.
Additionally, heavy-duty eccentric shafts and bearings ensure the shock resistance of the moving jaw assembly.Furthermore, we install heavy-duty protective plates above the moving jaw to withstand the strong impact of materials.

②High-quality material precision machining.

First, we use high manganese steel for the jaw plates and side guard plates. Next, we make the toggle plates from gray cast iron. Additionally, we craft the eccentric shafts from high-strength forged steel. Moreover, we produce these components through multiple precise machining, heat treatment, and flaw detection inspections—and this production process ensures they have sufficient rigidity and strength.

③Overload protection mechanism.

When the device operates, materials exceeding its crushing capacity may enter the machine. These materials can negatively affect the device’s operation and may even damage it. In such cases, the toggle plate will break on its own to protect the device from damage.

④Easy to operate and maintain.

First, the gasket-type discharge adjustment device and centralized lubrication system help operators operate and maintain the machine easily.Additionally, the jaw plate has a symmetrical structure—this design specifically lets operators reverse it for continued use after wear.This reversal, in turn, extends the jaw plate’s service life and reduces replacement costs.
