Natural mineral fertilizers generally refer to various mineral or rock resources other than traditional N, P, K and other fertilizers that can be directly utilized for agricultural and forestry production without complicated processing. Can granite gravel be used as fertilizer? Of course, we can use it as fertilizer, soil conditioner, fertilizer additive, etc. after simple processing and crushing. It has great potential for development and utilization.

The application of finely ground carbon black are very wide. And it has excellent properties such as small particle size, large specific surface area, large surface energy, strong adsorption capacity, high purity, high stability, reinforcement, thickening and thixotropy. At the same time, it has excellent properties in light absorption, magnetism, thermal resistance, It also shows unique properties in terms of catalysis and melting point, and is widely used in various industries as additives, catalyst carriers, petrochemicals, decolorants, matting agents, rubber reinforcing agents, plastic fillers, ink thickeners, and metal softeners, Polishing agent, insulation filler, advanced daily cosmetic filler and spray material, medicine, environmental protection and other fields.

At present, kaolin has become an indispensable mineral material in the ceramics, papermaking, rubber, refractory and chemical industries. So how should we choose the direction of kaolin deep processing?

Artificial sand production is the most technical and difficult link in the production of sand and gravel aggregates, and it is particularly important for roller compacted concrete. In order to ensure the stone powder content of the finished sand and gravel, it is necessary to process finer sand powder through a sand powder Raymond mill.

The Vertical mill ultrafine aluminum hydroxide process can be divided into two production processes: chemical method and physical method. The chemical method uses sodium aluminate solution as raw material, adds aluminum hydroxide seeds for seed separation treatment, then separates the slurry from liquid to solid, washes the separated solids, and then processes them after drying to obtain the product. The median particle size of the product can reach between 1-2um. The physical method uses aluminum hydroxide coarse powder as raw material and uses grinding equipment for physical crushing or cyclone collection to obtain ultra-fine-grained aluminum hydroxide. The median particle size of the product can reach between 3-5um. Aluminum hydroxide vertical mill is an ideal equipment for producing ultra-fine aluminum hydroxide powder by physical method.
