China Crushing Vibrating Screen Equipment Description Jaw crusher is mainly used for coarse crushing and medium crushing of various materials with compressive strength not exceeding 320Mpa. It has a large crushing ratio, high output, uniform product size, simple structure, reliable work, easy maintenance, low operating cost, etc. Features. The crusher has been widely used in mining, smelting, building materials, highway, railway, water conservancy and other industries. Advantage 1. Large crushing ratio and uniform product size; 2. Gasket-type discharge opening adjustment device is reliable and convenient, with a large adjustment range, which increases the flexibility of the equipment and can meet the needs of different customers; 3, the lubrication system is safe and reliable, the replacement of parts is convenient, and the maintenance workload is small; 4, simple structure, reliable work, low operating cost; 5. Low noise and less dust. Features 1. Simple structure and stable operation The bearing seat adopts an integral cast steel structure, which reduces the burden of the two-piece bearing chamber on the frame and increases the stability of the whole machine structure. In addition, the heavy-duty eccentric shaft is processed by forging blanks, which makes the jaw crusher more stable. 2. Hydraulic control, easy to clean the cavity Equipped with a hydraulic oil station, the lubrication system of the machine can supply oil to the parts that need to be lubricated, and provide protection for the machine operation. At the same time, if the crusher is stopped under load, the hydraulic cavity cleaning system can clean the crushing cavity, which greatly reduces the downtime. 3. V-shaped structure, tooth-shaped guard plate The design of "V" type crushing cavity and tooth-shaped guard plate is very reasonable, so that the actual feeding size of the equipment is the same as the theoretical feeding size, which can make the crushing area larger, and the material will not be blocked in the crushing cavity. The crushing efficiency becomes stronger and the utilization rate of the jaw plate is increased. 4. Wedge device quick adjustment The use of a wedge discharge opening adjustment system allows the machine to adjust the discharge opening to a predetermined value within a few minutes even when the machine is idling. With the cooperation of the hydraulic system, it can be automated, which is better than the old gasket type discharge opening. Simple and fast adjustment system. Working principle The jaw crusher is driven by a motor to drive the belt and pulley, and the movable jaw is moved up and down through the eccentric shaft. When the movable jaw goes down, the angle between the fixed jaw and the movable jaw becomes smaller, and the material is crushed to achieve the purpose of crushing; when the movable jaw rises. When the angle between the fixed jaw and the movable jaw becomes larger, the movable jaw leaves the fixed jaw under the action of the pull rod and the spring. At this time, the crushed materials are discharged from the lower mouth of the crushing cavity.China Crushing Vibrating Screen Equipment website:http://www.daynn-machinery.com/crushing-vibrating-screen-equipment/
