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.

Также важно отметить, что обучение и развитие кадров - это основа успешного бизнеса. В Кыргызстане существует нехватка квалифицированных специалистов в области машиностроения и производственных технологий. Компании, которые занимаются производством грязных насосов, должны инвестировать в обучение своих сотрудников, проводить стажировки и курсы повышения квалификации. Это не только повысит навыки работников, но и улучшит конкурентоспособность продукции.

Jaw plates are commonly made from manganese steel, an alloy that boasts high wear resistance and toughness. Manganese steel typically contains between 11% to 14% manganese, which contributes to its unique and advantageous properties. The addition of manganese enhances the alloy's hardenability, allowing it to become exceptionally hard when subjected to heavy impacts. This characteristic makes manganese steel an ideal choice for high-stress applications, such as crushing abrasive materials in mining.

  • A last and even more important, additional advantage of polyamide is the excellent thermal insulation. While aluminium scores much less well than wood and PVC in that area, it performs at least as well in terms of Uf value thanks to the polyamide strips (which insulate 500x better than aluminium).

  • Another option is to attend trade shows or home improvement expos where wrought iron suppliers often showcase their products

  • On the other hand, wrought iron fencing is celebrated for its timeless aesthetic and artisanal qualities. The hand-forged nature of wrought iron permits a wide range of output: everything from simple designs to highly intricate workmanship that can be more detailed than most cast iron. The forging process also imparts wrought iron fences with a higher resistance to impact and bending, making them more durable in certain environments.
