The sand making machine is one of the standing machinery for stone crushing and sand making machine. It provides a large number of high-quality sand for high-standard sand, railway, paving, construction, water conservancy and hydropower projects. The equipment mainly uses the hammer body mounted on the rotor running at high speed to crush the material and accelerate the crushing operation of the material by the mutual friction between the materials. There are two ways to break the sand making machine: “stone hitting stone” and “stone hitting iron”. What difference do they have?
1. Stone-rock–installation of upper and lower striking guards on the wall of the crushing machine of the sand making machine, so that the ore material accelerates when the material is accelerated, and the lining layer formed around the material is impacted, rubbed or material and material It breaks at high speed and does not directly contact the metal of the equipment. This way reduces the wear and tear of the parts and prolongs the service life. “Stone stone” is suitable for medium and hard abrasive materials, such as basalt, and the finished product has good grain size, but the powder content is slightly more, which is more suitable for shaping ore materials.
2, stone hit iron - different from “stone hit stone”, the sand making machine in the crushing chamber wall will be replaced by the lower guard plate into a weekly shield, the ore material is directly impacted on the weekly guard plate when the picking wheel is accelerated and thrown The crusher and the crusher collide with the material in the crushing chamber under continuous impact, and the ore material is broken more fully by impact, friction and grinding, and the finished material has smaller particle size. “Stone iron” is suitable for materials with low abrasiveness below medium hardness, such as limestone, etc., and the crushing efficiency is also high. However, due to the impact crushing, the peripheral guard plate is high in grinding, the cost of the wear parts is relatively high, and the finished product shape is slightly poor, which is more suitable for sand making.
The different differences in the way of crushing are important factors that influence the choice of the user. Different user requirements also affect the choice of the crushing method of the sand making machine. Only the right one is right.
