After twenty years of development, Hong Li has become one of the country's largest mining manufacturing, professional equipment and sand crushing well-known enterprises. The company set up a professional R & D, management, production, sales and service team, to achieve the perfect combination of R & D and production;. After more than twenty years of development, has now become the largest scale, professional production of mine crushing, sand and gravel equipment, one of the well-known enterprises.
Today, Acer Acer machine specializing in the production of broken equipment manufacturers -PEV series jaw crusher, that is, the European version of jaw crusher. The unique V cavity design is widely used in the coarse and broken stone. Breaking strength than 300Mpa of all kinds of ore and gravel, such as metal ore, gravel crushing, construction waste crushing, crushing raw materials such as cement factory. For the highway, railway, bridge, hydropower dam construction, concrete mixing stations and other industries to provide high quality materials.
Working principle of jaw crusher:
Acer PEV series jaw crusher combined with the characteristics of the European version of jaw crusher, the use of mechanical and electrical integration mechanism to effectively reduce power waste, extend the service life of V. The motor belt drives the main belt wheel through the V, the main belt wheel drives the eccentric shaft, the movable jaw according to the trajectory has been set for reciprocating under periodic changes before and after exercise, and the crushing cavity of the material to be broken, the material by gravity from discharged.
So, what are the characteristics of jaw crusher products are mainly reflected in the following areas:
1, modular non welded structure
Improper welding can make the crusher material to change its performance, affecting the overall life of crusher, resulting in unnecessary maintenance, and delay the production. Large and small machine - a new type of jaw crusher before and after the use of separate files with the side plate, the integral bearing seat, pin plug connection, and make the transport of crusher more convenient.
2, integrated motor installation
The factory has installed crusher motor frame, motor frame and Hubei breaking machine is integrated, reduces the Hubei broken machine installation space and V length. Synchronous motor and crusher, increased V belt life.
3, finite element analysis
PEV series jaw crusher adopts the professional mechanical design software to assist the design. From the part modeling to the mechanism analysis, from the dynamic analysis to the finite element analysis, the whole process is controlled effectively.
4, crushing cavity optimization
Optimization of crushing cavity design with a reasonable stroke, which makes PEV series jaw crusher is higher than the yield of traditional crusher. No matter the pebble is broken, the building garbage is broken or all kinds of ore are broken, there is a matching tooth plate.
5, more convenient adjustment
Easy to achieve automation: wedge adjustment. Mechanical adjustment can make the crusher either at work or shutdown can adjust the discharge size and replace the hydraulic adjustment, can make the crusher to achieve automatic control by pressing the button to adjust the preload and the movable jaw.
6, the selection of accessories
PEV series jaw crusher to provide a variety of accessories, including feed hopper, flywheel belt wheel safety cover, automatic lubrication system, hydraulic adjustment system. These parts can greatly improve the efficiency of equipment, reduce production costs.
7, structural optimization
The mechanism analysis is used to optimize the moving jaw stroke, and the stroke is larger than that of the common jaw crusher.
8, production and processing
PEV series jaw crusher parts are made of high quality alloy steel and hot rolled alloy steel plate to ensure the service life and stability.
9, increased bearing
The PEV series jaw crusher adopts 4 bearings of the same size, which is larger than the others with the same specification, and the service life is longer. The maintenance time of the movable jaw assembly is reduced, and the period of bearing replacement is prolonged.
10, discharge port hydraulic adjustment system (optional)
For large jaw crusher can be equipped with hydraulic adjustment system. Through the cooperation of the hydraulic cylinder and the accumulator, the purpose of automatically adjusting the discharge port and pre tightening the movable jaw is achieved. The safe and reliable hydraulic system reduces the preparatory work before starting, improves the work efficiency, and ensures the safe operation of the main engine.
The above data indicate that the crusher production is based on the average density of 1.6t/m3. Feeding and discharging smooth, no blocking phenomenon, the maximum feed size is the feed inlet size x0.8. In addition, the yield is also related to the mud content, water content, bulk density, fragmentation and so on.
At the moment, companies are trying to promote the transformation and upgrading, large and macro in the transformation and upgrading of the road also stepped up the pace. The spirit of "professional, dedicated, expert" concept, constantly upgrade in the product manufacturing process, management level, the perfect realization of the development and production of the combination and from "dahongli manufacturing" to "create dahongli".
