Introduction to the principle of sodium alginate crushing unit

Sodium alginate crushing unitUsing liquid nitrogen as a cold source, liquid nitrogen is directly sprayed onto the material through a special process to instantly cool it down and catalyze it before entering the crusher for crushing. The crushing process forms a closed-loop circulation system, and the entire equipment is enclosed in a thermal insulation layer, which fully utilizes energy and saves energy consumption, greatly reducing the cost of use. Due to the fact that liquid nitrogen temperature can reach below zero190The temperature inside the pre cooling chamber and the main unit during crushing can be reduced to below zero through special treatment30-40Long term normal operation ensures temperature stability and reduces unnecessary loss of liquid nitrogen.

This unit has been widely put into use in the industry

Zhongkai brandSodium alginate crusherAdvantages:

1.Due to the fibrous nature of the raw material, in order to prevent bridging after entering the silo, the material is evenly fed into the feeding screw through blade stirring.

2.The material is dynamically pre cooled, and a diffusion type showerhead is used in the spiral conveyor to ensure more thorough cooling of the material and save liquid nitrogen energy consumption. (Conventional freezing uses a two-stage pre cooling system consisting of a pre cooling chamber and a spiral conveyor.).

3.Specially tailored to the special characteristics of materials, the main blade is used to achieve better crushing effect, greatly reducing the electricity cost of the main machine and achieving higher production capacity.

4.The material is catalyzed by a parallel spiral conveyor and enters the main machine. After being crushed by the main machine, the finished product with the desired particle size is transported by a negative pressure induced draft fan into the cyclone separator and then into the material bin. A portion of the exhaust gas is recycled into the main machine as supplementary air flow, while the excess exhaust gas and micro powder enter the dust removal system. The micro powder is filtered and recovered, and the exhaust gas reaches *. The entire unit achieves dust-free production, with a simple structure that reduces equipment energy consumption and facilitates equipment disassembly and cleaning.

Crushing process:

The material is transported into the buffer bin through vacuum conveying (the buffer bin is equipped with an air hammer to prevent the material from bridging and affecting the crushing capacity). The raw material is transported into the crusher through spiral conveying for crushing. During the spiral conveying process, liquid nitrogen is injected simultaneously, and the raw material is uniformly pre cooled into the main machine for crushing through diffusion type spraying. During the crushing process of the host, there is an additional injection of liquid nitrogen to ensure that the host operates for a long time without heating up.

Both the front end and the main unit of the spiral conveyor are equipped with temperature probes, which can adjust the injection amount of liquid nitrogen through temperature display to avoid unnecessary losses.

The host generates a strong air flow through the wind wheel cutter and negative pressure of the induced draft fan to transport the crushed finished raw materials into the cyclone separation. After the material gas separation, it is discharged by the closing fan for packaging. (The silo is equipped with an air hammer to avoid bridging of crushed materials and prevent discharge.) Most of the tail gas vaporized by liquid nitrogen is circulated into the host as supplementary air flow. The excess tail gas carries some micro powder and is separated by the cyclone separation. After the material gas separation, it enters the dust removal and filtration to meet the standard discharge.
