The stirring system of VKM-5 double-shaft differential vertical kneader consists of mixing kettle, solid paddle and hollow paddle. The inner wall of the mixing kettle is a hollow thermal insulation layer, which is filled with 30 ℃ constant temperature water provided by the water supply system.

Improvement of Sodium Silicate Binder by Syrup

Improvement of Sodium Silicate Binder by Syrup

In the past, the binder used in chemical hardening method was only sodium silicate, and its strength and surface strength were most suitable when modulus was 2. Even so, the ventilation time is relatively long and the collapse is poor. Therefore, it is necessary to add appropriate additives to improve the performance of sodium silicate. Through experiments on various organic materials, it is found that syrup has the lowest price and can improve the performance of sodium silicate. In addition, starch was also tested.

Under the condition that the proportion of moisture and clay is unchanged and the pile tightness is the same, the wet compressive strength and dry tensile strength will be improved with the increase of pulp waste liquid in the mixture. When the addition amount reaches 6-7%, the wet compressive strength will begin to decrease, but the dry tensile strength will not increase significantly.

It is necessary to ensure that foamed acid (foamed dilute sulfuric acid formed after the liquid formed by mixing concentrated sulfuric acid, water and foaming agent is foamed by compressed air) fully wetts the lint on the surface of cotton seed, The mixing quality of cotton seed and foamed acid is directly related to the consumption of concentrated sulfuric acid, water and foaming agent, and affects the productivity of subsequent drying and defoiling equipment and the amount of residual acid in seeds.

Cold Briquette of Ferro-Contained Waste

Iron and steel industry is an important source of solid waste. If these solid wastes are not utilized, it will not only occupy land, pollute the environment, but also waste limited resources. Steel and rolling system is an important source of solid waste in iron and steel enterprises. Its solid waste has high iron content. However, if it can be utilized, it can not only reduce environmental pressure, but also achieve the purpose of reducing cost and increasing efficiency. Judging from the application situation in the industry, the cold consolidation pellet metallurgy effect of converter dust removal ash is remarkable, which has the advantages of reducing the consumption of lime and other auxiliary materials, melting slag in advance, reducing the consumption of steel materials and the like, and has achieved remarkable results.

Two factors determine the strength of cold briquettes. One is the molding pressure, the material mixed with binder forms briquettes under the action of appropriate pressing force. The second is to let the green ball remove water and carry out carbonation reaction through certain drying and consolidation methods to improve its strength. There are many equipment used for drying, such as drum dryer, shaft furnace, consolidation tank, etc. According to the principles of high efficiency, convenience and economy, the advantages and disadvantages of various drying equipment are compared. We find that it is better to adopt the two-time curing method of grate reinforcement and tank formation.
