The utility model discloses a zinc oxide grinding machine which comprises an outer machine box, an inner barrel body and a discharging barrel, the discharging barrel is installed in the center of the bottom of the outer machine box, a discharging motor is installed at one end of the discharging barrel, and the output end of the discharging motor extends into the discharging barrel and is provided with a spiral stirring paddle. Fine grinding blocks are arranged on the inner wall of the discharging barrel between blades of the spiral stirring paddle; a servo motor is installed on one side of the outer machine box, and the output end of the servo motor extends into the ball milling bin of the outer machine box and is provided with an inner cylinder. Due to the adoption of the design of the double grinding balls, the contact area and the collision frequency of a grinding medium and a zinc oxide material are obviously increased. The protrusions evenly arranged on the outer side of the first grinding ball are matched with the grooves evenly formed in the outer side of the second grinding ball, the interaction between the grinding media is further optimized, the grinding process is more efficient, the zinc oxide can be ground to the finer granularity, and therefore the production capacity is remarkably improved.

This invention provides a slope protection material composed of recycled heavy metal tailings and its preparation method. The material includes: recycled heavy metal tailings treated with a heavy metal chelating agent as a heavy metal ion capture agent, the chelating agent being added at 0.05%–0.2% of the heavy metal tailings weight; recycled heavy metal tailings as aggregate, which is mixed with natural soil to form a base material at a ratio of 1:1.5–2.5; fine aggregate and fine sand, added at 5%–10% of the base material weight; and high-viscosity industrial-grade sodium alginate added as a water-retaining and reinforcing agent, added at 0.5%–2.0% of the base material weight. Additionally, 28% organic matter is added to the base material. The application of this invention effectively solves the problems of ineffective utilization of recycled heavy metal tailings and excessive use of scarce natural soil in existing technologies, and also addresses the issues of weak strength, poor effectiveness in steep slope treatment, and poor stability in existing slope protection materials.

In addition, the falling dust can be conveniently received and stored, which is convenient and efficient and improves work efficiency.

This utility model relates to a rotary kiln lining structure; each ring of the inner lining layer is provided with at least four evenly distributed lifting bricks, the inner surface of which protrudes from the inner surface of the microporous energy-saving inner lining brick. The lifting bricks on each ring of the inner lining layer are positioned one brick in the direction of rotary kiln operation, and form a corrugated spiral protrusion structure for tipping, lifting, and pushing materials. This improves the heat energy conversion rate, thereby improving the quality stability of the rotary kiln, increasing output, saving energy and reducing consumption, and achieving significant environmental protection effects, ultimately achieving the goal of a low-carbon economy.
