A talc crushing and grinding system for silicone rubber production

technical field

The invention belongs to the technical field of rubber production, in particular to a talc crushing and grinding system for silicone rubber production.

Background technique

With the rapid development of modern industry, especially the chemical industry, there are many kinds of rubber products, but the production process is basically the same. The production process of products made of general solid rubber (raw rubber) mainly includes: raw material preparation, plasticizing, mixing , molding, vulcanization, rest and inspection. The main materials of rubber products are raw rubber, compounding agents, fiber materials and metal materials. Some materials need to be processed in order to make the raw rubber and compounding ingredients evenly mixed with each other. Block compounding agents such as paraffin wax, stearic acid, rosin, talc, etc. need to be crushed, and talc is used as a filler for rubber.

Talc is formed by long-term physical and chemical changes of other minerals underground. It is a kind of "metamorphic mineral" and is usually metamorphosed from magnesium rocks. For example, dolomite composed of magnesium carbonate, under the action of high-temperature hydrothermal fluid rich in silicon, its main component may gradually become hydrated magnesium silicate, that is, talc. And some rocks containing olivine, enstatite, hornblende and other magnesium-containing silicates will undergo compositional reorganization in a similar process and transform into talc. Talc is generally blocky, leafy, fibrous or radial in shape, white or off-white in color, and can have various colors due to other impurities. Talc has many uses, such as refractory materials, paper making, rubber fillers, pesticide absorbents, leather coatings, cosmetic materials, and engraving materials.

When using talc, it needs to be ground into powder. Talc powder has a wide range of applications. For example, talc powder can be used in rubber to increase the volume of rubber, improve the processability of rubber, play a semi-reinforcing or reinforcing role, and adjust the rubber. hardness. In coatings, talc powder is used as a filler, which can act as a skeleton, reduce manufacturing costs and improve the film hardness of coatings. In plastics, it can increase the volume of plastics, reduce product costs, improve the dimensional stability of plastics, and the hardness and rigidity of plastics. Talc powder can improve the heat resistance of plastics and improve the astigmatism of plastics. In some existing grinding methods, the talc is ground into a gravel-like structure, with uneven particle size and irregular shape, which affects the quality of the final product. There is an urgent need to develop a talc grinding system that meets market demand, has high grinding shape, uniform particle size, high grinding efficiency, and effectively improves the utilization rate of raw materials.

There are also some technical solutions for talc grinding in the prior art. For example, a Chinese patent with application number 201710485539.4 discloses an ore crushing device for smelting, including a bottom plate, a collection frame, a support rod, a crushing frame, and a discharge pipe. , valve, support plate, top plate, first cylinder, crushing plate, rotating device and pushing device, the middle of the top of the bottom plate is symmetrically connected by bolts to install a support pole, and the top of the pole is connected by bolts to install a crushing frame. The lower part of the right side of the crushing frame is connected with a discharge pipe, which communicates with the inside of the crushing frame. The material part is in contact with the crushing frame. The right side of the top of the bottom plate is connected by bolts to install the collection frame. Support plate, the top of the support plate is connected by bolts to install the top plate, the bottom of the top plate is provided with a rotating device, the rotating part of the rotating device is connected with the first cylinder, the first cylinder is vertically arranged, and the telescopic rod of the first cylinder The crushing plate is installed by bolt connection, and the crushing plate is located directly above the crushing frame. This technical solution realizes the grinding of ore, but it needs to be stopped when loading materials, and the material can be loaded only after the cylinder is retracted, which affects the grinding efficiency; the cylinder rod of the cylinder is extended during work, and the poor mechanical properties are not conducive to high-speed grinding; the grinding disc The grinding method is fixed, the grinding is not sufficient, and the grinding efficiency is affected at the same time; it is not convenient for discharging.
