PLS 850 High-Efficient Vertical Shaft Crusher Machine For Sand Marker

Description

The PLS series vertical shaft impact crusher absorbs years of research and development experience and technical concepts. It adopts a new four-port impeller design structure and a special sealing structure to prevent oil leakage in the bearing cylinder. It has a new type of sand making and crushing equipment with a number of national patent technologies. The characteristics of energy saving, long service life and wide range of applications have helped Dashachang gradually move towards large-scale and centralized production to meet the country's requirements for environmental protection and production capacity.

Features

• Reasonable inner structure makes the material protect itself, which makes the life of the impeller longer. And the cost will be lower.
• There are different speeds (high, medium, low) to choose which can fully show the efficiency of the machine. It has the function of crushing, sand making and shape making.
• Higher accuracy of manufacture makes the anti-unbalanced ability of the impeller better.
• The wear parts are standard modularity. It is convenient for maintenance.

Advantage

• Key components such as impeller, bearing barrel, lower part of the machine body and other new designs: the impeller adopts a four-port design to increase the probability of material throughput and the collision between materials; the bearing barrel adopts a unique exhaust and dust-proof device and sealing structure to prevent dust from entering the lower bearing The cover is leaking oil; the lower part of the body is changed from a "well" structure to a "cross" structure to prevent materials from blocking the discharge channel.
• The standard self-lifting arm is coaxial with the lifting arm to facilitate the maintenance of the impeller and the bearing barrel; the hydraulic jack is used to lift the hopper, which is easy to maintain; the height of the guardrail is reduced to avoid interference when the hopper is unscrewed.
• It adopts thin oil lubrication and is equipped with an air-cooled system. It is controlled by PLC and intelligent instruments, which can realize automatic lubrication control, and the lubrication temperature can be adjusted to provide more ideal working conditions for the bearing.

Working Principle

• Stone Beat Iron: The materials fall vertically and uniformly from the top of the machine, and enter into the revolving impeller at high speed through the feed pipe. Then they are shot out from the discharge outlets of impeller by the action of the high-speed centrifugal force, and at high speed strike and crush with impact plate around the impeller.
• Stone Beat Stone: The materials fall vertically and uniformly from the top of the machine. One part of them enter into the revolving impeller at high speed through the distributor and feed pipe, and are shoot out from the discharge outlet of impeller by the action of the high-speed centrifugal force. Then at high speed they are smashed with another part of the materials that have been distributed around impeller through the distributor. After smashing each other the materials shall form whirlpool and impact many times caused by striking and attrition in the impeller and crushing chamber.
