AAC Concrete Block Machine Making Machine - JC series Jaw Crusher Machine for underground mine

Jaw crusher AAC Block Plant Machinery

Description:

The JC series jaw crusher machine is a new type of jaw crusher with optimized and developed design on structure, material selection, manufacture process and assembly, which is based on absorbing the international advanced technology and applying our company's decades design concept and technology of jaw crusher. With the feature of smart structure and excellent performance, the machine is suitable for crushing all kinds of hard and abrasive rock and mineral ore. In order to meet the needs of different working conditions from the customers, this machine can apply modular bolt connecting frame without welding.

Features:
STRONG STRUCTURE:
There are two types of frame for JC Jaw Crusher: welded frame and modular bolt connecting frame. Generally we apply the welded frame for the small and medium-sized jaw crusher and the modular bolt connecting frame for the large-sized jaw crusher. The welding method for the welded frame greatly reduces the stress concentration to ensure the equal strength of the frame in different directions. They have the features of impact resistance, even force and low failure rate, etc. The modular bolt connecting frame has the features of fatigue strength and high reliability. The non-welded method for the modular bolt connecting frame is very convenient for transportation and installation, especially suitable for the underground mine, high altitude mine and other places which are narrow or difficult for transportation.

OPTIMAL DESIGN OF CRUSHING CHAMBER:
Applying the V-type symmetrical design of crushing chamber, the actual width of the feeding opening is consistent with its nominal width. Also with the deep crushing chamer, tight nip angle and long stroke, the machine has lower energy consumption and better processing capacity and crushing performance.

SWING JAW ASSEMBLY:
The swing jaw assembly consists of forged eccentric shaft, high-duty rolling bearings and the swing jaw optimized by FEM analysis, which ensure the impact resistance and stability of swing jaw assembly. By using the labyrinth seal and centrailized lubrication system, there ensure no pollution to the bearing grease and convenient lubrication, also ensure long operating time and good stability.

PROTECTOR PLATE OF SWING JAW:
The protector plate installed on the swing jaw reduces the impact force from materials, which effectively protect the swing jaw and bearings inside.

QUICK AND CONVENIENT CSS ADJUSTMENT:
The JC Series Jaw Crusher applies mechanical or hydraulic discharge asjusting device for CSS. Compared with gasket adjustment, its double wedge adjustment is simple, safe and fast. It can also reduce the downtime.

BEARING:
The special bearing design ensures the big loading capacity, long service life and reliable operating.

ROD SPRING OR HYDRAULIC CYLINDER:
Eigher the hydraulic cylinder or rod spring will be used for swing jaw tension device. The rod spring applies advanced friction reducing devices which can make easy and qucik adjustment.

INTEGRAL BEARING HOUSE:
The integral casting bearing structure ensures the perfect match with the main frame, which avoids the unnecessary radial load to the bearings during the fastening process of integral bearing house. This makes bearing running more smoothly.

INTEGRATED MOTOR DESIGN:
The integrated design of the motor base together with the main frame not only saves the installation space of jaw crusher, but also reduce the length of the V-belt. As a result of synchronized motion of the frame, motor base and motor, adjustable motor base realize V-belt tension adjustment, increase the life time of the V-belt.

RUBBER DAMPING DEVICE:
The special rubber damping device effectively absorbs the equipment vibration. Meanwhile it allows crusher vertical and longitudinal displacement, which reduces the impact to the foundation base.
