  • Top 10 recommendations for increasing ball mill production and reducing consumption
    Top 10 recommendations for increasing ball mill production and reducing consumption

    Ball mills are widely used in industry,  increase the production and reduce the ball mill consumption is great significance for the industries. As a professional manufacturer of ball mills, Through our research and analysis, the following suggestions are made for increasing the ball mill production and reducing the ball mill consumption . 1.Reduce the moisture content of the grinding material When the moisture content of the material is not very large, the following measures can be taken: increase the area of the raw material storage yard (shed) and strengthen the natural drying of the raw materials; the raw materials should be stacked in the stack during the rainy season; the factory that buys raw materials from the outside must be strictly controlled.   The dried and wet materials are mixed into the mill or pre-homogenized. Make the water even and the quality is even. When the material moisture is too large, a rotary dryer can be added. Adding a dryer requires a lot of money, so we need to conduct a detailed feasibility study. 2.Properly reduce the material feed size  The economic balance and capacity balance of the crusher and the grinding system should be considered comprehensively, so it is proposed to appropriately reduce the particle size of the milled material. The average particle size of the milled material is reduced from 20mm to 10mm, then the output of the mill can be increased by 20%. it is also possible to reduce the particle size of the grinding material by adding a first-stage crusher. 3.Choose the right amount of grinding balls and proportion (1) increase the ball load appropriately Increasing the loading or filling rate of the grinding balls within a certain range ,can increase the output of the ball mill and reduce the power consumption .  However, the ball load is not as high as possible, the load is large to a certain extent, and the grinding efficiency is rather reduced. In addition, the quantity of grinding balls in each bin must be distributed and combined with a reasonable proportion,then can  increase the mill output. (2) Suitable grinding balls proportion  Generally, the first compartment can select balls size within 80-110mm. The second compartment select slightly smaller balls than the fist compartment . If the first compartment balls are 60mm, the second compartment can be selected as a 60mm or 50mm balls . 4.Control the appropriate discharge grid width  The width of the discharge grid is not only related to the material passing amount , but it also limits the larger particle size through the material. It is more important to reasonably control the grid width of the first compartment . Because the grid width of the first compartment is controlled, the large granular material can be effectively restricted to enter the second compartment, and the larger material can be clamped in the first compartment . then can improve the ball mill capacity . Generally , the dry proc...

  • Construction Waste Recycling Plant
    Construction Waste Recycling Plant

    Construction and demolition (C&D) materials account for almost 22 percent of the waste stream. Many of these materials can be reused or recycled, thus prolonging our supply of natural resources and potentially saving money in the process. Common Construction and demolition materials include lumber, metals, drywall, masonry (brick, concrete, etc.), carpet, plastic, pipe, paper, cardboard, rocks, dirt, or green waste related to land development. Of these, metals are the most commonly recycled material while lumber makes up the majority of debris that still goes to a landfill. Construction waste recycling is the separation and recycling of recoverable waste materials generated during construction and remodeling. Some materials can be recycled directly into the same product for re-use. Others can be reconstituted into other usable products. Construction Waste Recycling Plant Flow And Description
