The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal.

  • The production of potassium sorbate involves several key steps, which are vital for ensuring high-quality output. Typically, potassium sorbate is synthesized from sorbic acid and potassium hydroxide or potassium carbonate. The process begins with the neutralization of sorbic acid with the appropriate potassium base, resulting in the formation of potassium sorbate. This reaction must be conducted under controlled conditions to ensure the purity and efficacy of the final product.
