Design Principles of Laboratory sealed jaw crushers

Laboratory sealed jaw crushers is on medium and fine crushed materials for the purposes of laboratory and production and especially as environmental protection equipment for the coal, electricity, Gold Mining Machine, geology, chemistry, metallurgy -, building materials and other industries. The product is indicated by the only company of the former Ministry of Geology and Mineral Resources, manufactured in accordance with industry standards.

XPC model Sealed Jaw Crusher is a new generation of crushing plants with slightly open dynamic and static jaws, convenient cleaning and without mixing of samples. It is capable of fine and medium refractive a variety of ores and materials having a compressive strength of 24kg/cm2 and down. with large crushing ratio, uniform particle size and setting the output size.

I. Main Design and functional principle

This machine is composed mainly of machine body, movable jaw, eccentric shaft, jaw plate, flywheel, pulley, movable part, motor, hopper and the collecting funnel.

The three angles of motor pulley drive the eccentric shaft through the pulley to get move the movable jaw along the track already adapted to crush as the materials in the crushing chamber.

The machine body is all steel. Fixed jaw plate is mounted on its front wall. Edge plates are provided on the side wall of the frame on the left and right of the crushing chamber, in order to prevent the abrasion of the side wall of the frame, is mounted.

The movable jaw is a form of casting. On the front of active jaw plates are installed. At its peak, the eccentric shaft and bearings hanging over the frame. Your floor is supported on the moving parts and. In rolling contact with the moving parts At the two ends of the eccentric shaft is the flywheel and the pulley is installed at the groove. The machine body is connected to the machine base and the slideway of the motor is fixed onto the machine base with bolts.

The supporting system of moving jaw is equipped with riveting pin connection device. If hard objects that can not be broken (eg pieces of iron) in the materials crushed, ie the crusher is overloaded, the pin will quickly rivering break, play a protective role to preserve other important parts of the crusher from damage.

A grip having a function of angular displacement provided, installed on the left side of the machine. This handle is used to adjust the size of the outlet opening. The distance between the outlet openings can be adjusted by the adjustment of the handle. In addition, when the jaw plate is abraded, the gap between discharge openings can be compensated through the adjustment of the handle.
