Single-stage hammer crusher, high-efficiency hammer crusher, sanding machine, vertical shaft hammer crusher, reversible hammer crusher.
Hammer crusher is divided into: single-stage hammer crusher, high-efficiency hammer crusher, sanding machine, vertical shaft hammer crusher and reversible hammer crusher. A ring crusher that replaces the hammerhead of a hammer crusher with a steel ring is a variant of the hammer crusher. It uses a combination of high-speed impact and low-speed rolling to break up the material, thus obtaining a finer product, mainly used to crush coal for power plants, but also for the crushing of gypsum, salt chemical raw materials and some medium-hard materials.
Hammer crushers are used to break a variety of medium hard and abrasive materials. The compressive strength of the material does not exceed 100 MPa, and the water content is less than 15%. The materials to be crushed are coal, salt, white Asia, gypsum, brick, limestone and the like. It is also used to crush waste of wood, paper and broken asbestos cement with strong fiber structure, elasticity and toughness to recover asbestos fiber and so on.
Due to the different working environment of the hammer crusher, the application of the hammer crusher should pay more attention to some problems. Here are some questions you should pay attention to when testing the rotor and spindle of the hammer crusher:
First, the applied straightening force should not be too strong to prevent the main shaft from cracking at the hidden spot of the crack;
Second, when the amount of bending is large, it should be straightened several times;
Third, the correction value should appropriately exceed the bending value of the shaft to eliminate the effect of the springback deformation of the shaft after removing the straightening force;
Fourth, in the straightening, after adding the straightening force, it should stay for a while, and at the same time, gently tap the shaft surface with a small lead hammer to eliminate the internal stress and prevent deformation after straightening. ;
Fifth, during the straightening process, the bending value of the shaft is continuously measured until it meets the standard. That is, when the axis is Φ200-300, the bending value should not exceed 0.06mm. After straightening the shaft, the bending value should not exceed 0.1-0.15mm.
As the main force-receiving part of the crusher, the main shaft is checked and optimized by the traditional method, and the process is complicated and cumbersome. The technicians provide a reliable basis for redesign and modification through the tracking and service of the various products to the crushed and broken materials. According to the analysis results, the performance is evaluated, and based on this, a reasonable structural size is obtained. After optimization, the spindle quality of the hammer crusher is reduced, and the strength and rigidity are ensured. Http://

AMICI reflection prism called also roof prism or right angle roof prism,which deflects the beam through an angle of 90 degree and inverts the image. For this reason,this prism is perfect for erecting images inverted by the objectives.
We supply many types of high precision optical prisms,such as Wedge Prism,Right Angle Prism,rhombohedral prism,Dove prism,Penta prism,pyramid prism,dispersing prism,Reflection prism etc. Each having a particular geometry to achieve the reflections necessary to perform a specific imaging task.Reflecting prisms may invert,rotate,deviate or displace a beam.dispersing prisms produce spectral separation for spectroscopic applications or for tuning a laser output.Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering.Irregular-shaped or non-standard size prisms may be available by custom order.
