The double-roll crusher is also called the double-roll crusher. The double-roll crusher is a machine that takes materials into the crushing zone and uses the friction force of the roller surface to withstand squeezing or splitting. . It is mainly suitable for medium and fine crushing of brittle lump materials in mining, metallurgy, chemical industry, coal mine and other industries. The discharge particle size is adjustable, and it can crush materials with compressive strength ≤ 250MPa. As long as the iron and impurities are removed, it can be crushed directly. The crushed material has a uniform crushing particle size and a large crushing ratio, which simplifies the beneficiation process and reduces investment and production costs.
The double-roll crusher mainly relies on the squeezing force of the opposite rotation of the grinding rollers to successfully crush the material, and the wedge block set between the two rollers can adjust the particle size of the crushed material, and the operator only needs to adjust the wedge block The upper bolt can be pulled up or down to adjust the discharge particle size, which greatly facilitates the operation steps of on-site personnel and improves the quality of the product. The material to be crushed is fed by the feeder and falls between the two rollers of the pair of rollers, and is crushed by the squeezing force when the rollers rotate in opposite directions. The finished material falls naturally from the gap between the rollers, which is what the customer needs Of sand and gravel. If the stone to be processed is mixed with high hardness or unbreakable materials, the double-roller crusher increases the distance between the two rollers to allow the overly hard or unbreakable materials to fall smoothly and complete the self-protection of the machine from damage.
The performance characteristics of the double roller crusher in use:
1. The double-roll crusher has high production capacity, but the operating cost is low. The high income and low cost of the double-roll crusher means that the double-roll crusher brings high profits, so naturally, The more users are willing to choose to use the double roller crusher.
2. After the double roller crusher fails, it can be quickly repaired and can be used repeatedly. Save time and improve production efficiency.
3. The basic requirements of the roller crusher for the operator are not high, which makes the use of the double roller crusher more convenient. The double-roller crusher is widely recognized by users in terms of appearance, floor space, and good use effect.
The purpose and significance of the double roller crusher
1. Purpose: In metallurgy, mining, chemical, cement and other industrial fields, a large amount of raw materials and recycled waste need to be processed by a double-roller crusher every year. For example, in a concentrator, in order to separate the useful minerals in the ore into monomers, it is necessary to use crushing equipment to crush the raw ore to the particle size required by the grinding process. The raw materials need to be crushed with crusher equipment to achieve the particle size required for the next operation. In sectors such as coking plants, sintering plants, ceramic plants, glass industry, metallurgical industry, etc., crushing equipment must be used to crush the raw materials to the required particle size requirements.
2. Significance: In the chemical industry and electric power sector, after crushing equipment crushes and grinds the raw materials, it increases the surface area of the material and creates favorable conditions for shortening the chemical reaction time of the material. With the rapid development of industry and the rapid reduction of resources, the reuse of waste materials is particularly important in the production of various sectors. These waste materials need to be re-shredded and processed for recycling, thereby protecting the environment.
