BB fertilizer is usually called blended fertilizer, which is a kind of compound fertilizer with at least two nutrients of nitrogen, phosphorus and potassium in specified amounts made by dry mixing method. In the process of BB fertilizer production, the mixing process is the key link to determine the product quality and production efficiency. As the leading equipment in the mixing process, the performance of the mixer will directly affect the product quality and production efficiency. This article briefly introduces the 12 tons per hour BB fertilizer mixing equipment.

The compressive strength of different types of desiccated sludge briquette is obviously different with the addition proportion,The product is generally used in mining, sewage sludge, medical sludge treatment.Mainly due to the different composition of sludge itself will also cause the difference in its cohesiveness, generally expressed in water content, inorganic matter and the different unit points contained.

Mixing equipment is widely used in food engineering, chemical engineering, biological engineering and other industries. They have an important impact on the process effect and product quality. Along with the gradually perfect and mature production technology, the technological parameters of mixing equipment, structure and stability, especially in the process operating conditions under the condition of same capacity only different, this kind of device is often just the difference of shape size, volume, power, size, number of assembly structure of the equipment, spare parts and types are basically the same. This provides necessary conditions for the standardization, standardization and modular design of mixing equipment. This paper briefly introduces the development of 3d parametric CAD system for mixing equipment.

Pulp waste liquid is a good binder in the cold consolidation briquette industry, because of its low price, there are industrial cases instead of molasses as binder applications.

1. Molasses standard（Adapted from" QB/T2684-2005) 2. Ingredient list of sugarcane molasses from a sugar factory 3. Knowledge about molasses

Hot Briquetted Iron (HBI) is a premium form of DRI that has been compacted ata temperature greater than 650°C at time of compaction and has a density greater than 5,000 kilograms per cubic metre (5,000 kg/m3).

Through practice, it is found that the finished ore produced by grate rotary kiln process has the characteristics of uniform quality, good metallurgical properties, more fuel available and strong adaptability to raw materials. This paper introduces what equipment should be equipped with the production line equipment.

Mixing of highly viscous fluids is a common unit operation in industry, and many industrial sectors encounter mixing or kneading operations of highly viscous fluids, such as rubber, petroleum, plastics, coatings, inks, and synthetic fibers, cosmetics, pharmaceuticals, food, paper and cement industries.

Manganese powder ore generally refers to fine-grained concentrates obtained by beneficiation, and fine-grained materials containing manganese such as soot and ash obtained from smelting manganese ferroalloys in blast furnaces and electric furnaces. The briquette method is one of the manganese powder ore agglomeration methods.

The Pellet method represents the development direction of fine powdery iron concentrate, bentonite as a dry binder plays a decisive role in the process of caking, therefore, it is of great significance to study the bonding mechanism of bentonite to iron ore pellets.
