Equipment Introduction
High-efficiency fine crusher (also known as cement clinker fine crusher) is used for fine crushing operations before the mill in the cement production system. It can finely crush the clinker crushed by the grate cooler to reduce grinding power consumption and The purpose of increasing the output of the mill. Most of the domestic cement industry still uses fine jaw crushers to finely crush materials. The crushing and discharging granularity reaches a certain level, resulting in low efficiency of the grinding system and high energy consumption. However, Dingsheng high-efficiency fine crusher can average the materials. The particle size is reduced to 20%, which greatly increases the output of the mill.
This machine adopts the stone-on-stone crushing principle and optimizes the crushing chamber type. In addition to being used for clinker fine crushing operations, it also has the function of fine crushing and sand making, which can be used for crushing compressive strength. Various ore raw materials with a moisture content not exceeding .
Working Principle
After the raw materials are fed into the feed port of the high-efficiency fine crusher through the feeding equipment (such as belt conveyor, plate feeder), they enter the crushing cavity. The materials hit the high-speed rotating machine driven by the belt. The rotor is hit head-on by the hammer, and large pieces of material are immediately crushed. The broken materials fly up to the counterattack plate at high speed for the second collision and crushing. The rebounded materials collide with the subsequent flying materials. The broken materials enter the first cavity after being crushed. The crushing is repeated in the second chamber, and finally it is filtered and crushed by the discharge grate. Materials that meet the requirements are discharged from the grate slits, and the coarser materials return to the first chamber for re-crushing. Since the material layer is densely suspended in the crushing chamber, subsequent materials entering the crusher The material is shot into the dense material layer like a target, and the crushing cavity is like a hail of bullets. The materials collide with each other at high speed to produce efficient cleavage and crushing. The crushed fine particles are violently rubbed to produce a large amount of fine powder, and finally pass the test. The fine powder is discharged through the grate slits.
Performance characteristics
Adopting a three-cavity curved crushing cavity, the material can be hit more times, hard squeezed, friction reduced, and hammer head loss
. The gap between the impact plate and the hammer head can be easily adjusted, which can effectively control the discharging particle size
. It adopts a deflectable structure, which can prevent the hammer head from breaking to a certain extent in case of hard materials
. Hydraulic opening of the cover makes maintenance easier. Convenience
Install an iron discharge door at the outlet of the grate. If iron or hard materials cannot be broken, they can be discharged through the iron discharge door to protect the machine parts from being broken, but it must not replace the iron remover
The gap between the left lining plate and the hammer head is adjustable. When the particle size exceeds the specified value, the left lining plate or the lower impact plate will be pushed inward. The hammer head of the sandwich fine crusher adopts a cemented carbide combined structure and other special wear-resistant material, greatly improving the service life of the hammer head
