Optimizing the briquette processing technology and reducing environmental pollution Optimizing the briquette processing technology can effectively reduce environmental pollution and achieve the effect of maximizing the utilization of resources. The key to the selection and configuration of briquette equipment is the ratio of the binder, the selection of the briquetting machine, and whether the cooling of the formed product is in place.
1. Selection of binder: Choose a binder with low cost, wide source and good effect. The briquette is a coal product with a certain shape and certain physical and chemical properties. Its formation process is one or several kinds of pulverized coal and a certain proportion of a binder or a sulfur-fixing agent processed under a certain pressure. Soft pitch is generally used as a binder for briquette, but it has the disadvantages of high price and low conversion rate. Therefore, choosing a cheap, wide source, and effective binder to replace soft pitch is a key to the development of coking with briquette.
2. Fully kneading coal and binder It is particularly important to fully knead coal and binder during the pressing process of the briquette machine, and it is also an important link to ensure the effective use of the binder and improve the strength of the briquette. Enterprises should pay great attention.
3. Selection and configuration of briquette equipment: Selecting reliable briquette briquette machines, material conveyors with high working intensity and other equipment can improve production capacity and complete large workloads in a short time. Shorten working hours and bring more profit. Therefore, the selection of the ball press is very important.
4. Cooling of the formed product: Since the forming ball is carried out at 80-100mpa, the binder is evenly distributed on the surface of the coal particles, but it is still in the form of a liquid film, so the strength of the briquette is not large. The use of a mesh conveyor with air ventilation cooling can cool the briquette to improve the strength while conveying the briquette, but the transportation distance should be shortened, the drop between operation and storage should be reduced, and corresponding anti-breakage devices should be adopted. Some also unload the shaped balls to the pulverized coal conveyor belt and run together with the pulverized coal to reduce the impact and improve the overall ball rate.
