Blind Nuts

ACRO-PERDA has been manufacturing a stud, also known as a blind nut, in wear-resistant material for more than 30 years. The hexagonal nut or blind nut is made of cast iron to which a heat treatment is applied that provides a hardness of +/-63HRC, obtaining a piece with a high resistance to abrasion and wear, ideal for this type of piece, well, it is usually in contact with a multitude of abrasive materials used in the different application sectors such as quarries, cement plants (ball mills), mining machinery, public or agricultural works among a great long etcetera. We can manufacture custom parts, although the metric M8, M10, M12, M14 and M16 with hexagonal heads about 35 or 37mm are the most common in most sectors.
Acro Perda is a company specializing in Blind Nuts.

Wear-Resistant Cap Nut

Blind Nuts Wear Proof.:

Cap nut with a hexagonal head, made of wear-resistant cast materials.

ACRO-PERDA has over 40 years of experience manufacturing wear-resistant cap nuts. Having detected a high consumption of this spare part among our customers with hook cabinet and tunnel-type shot blasting machines, we began to manufacture our cap nut in a wear-resistant, high-strength and abrasion-resistant material.

The cap nut is made of a wear-resistant, cast alloy of iron, chrome (Cr) and nickel (Ni), which after heat treatment reaches a hardness of +/- 63 HRC. This hardness makes it highly resistant to abrasion and wear.

The cap nut is manufactured in the following sizes:

  • M8, M10, M12 with a 35 mm hexagonal head..
  • M14, M16 with a 37 mm hexagonal head.
  • Other sizes can be manufactured on request.
  • The cap nut can become a male nut by screwing on a hanger bolt of the required size.

Applications of the Wear-Resistant Cap Nut:

  • Attaching anti-abrasion rubbers, cabinet wear plates and liners for the inside of cabinet or tunnel shot blasting machines, protecting the screws exposed to the steel shot.
  • Attaching the liners screwed into the inside of cement mills, impact crushers and grinders, and linings for mixers.
  • Attaching and screwing in place impact plates for ball and ball bearing mills.
  • Screwing in place blades and subblades for buckets and mixers.
  • Protecting screws in places that suffer wear due to contact with dust, soil, steel shot and any other type of abrasive material.
  • Screwing in place of linings for mixers, mills and crushers.

Areas of Application:

  • Quarries, cement plants, mines (Ball mills).
  • Construction of conveyors.
  • Machinery for mining and public works.
  • Agricultural machinery.
  • Earth moving equipment.
  • Mechanical manipulation equipment.
  • Conveyor belts.
  • Public works.
  • Hoppers, feeders, silos, belt conveyors.
  • Aggregate plants.
  • Mineral classification.
  • Ferrous and non-ferrous metal foundries.
  • Car industry.
  • Shot blasting and painting.
  • Surface treatment.

One of the most important applications of the wear-resistant cap nut is in the cement plant, mining and quarry sector. The wear-resistant cap nut is used for attaching liners, protecting the screws inside the ball mills.

Ball mills are designed for the fine grinding and re-pulverising of a wide range of materials. Their versatility makes them suitable for mineral processing as well as numerous industrial applications.

They are widely used for processing cement, silicate products, advanced construction materials, refractory materials, chemical fertilisers, ferrous and non-ferrous metals, glass and ceramics, among many other materials.

Ball mills can operate in both wet and dry grinding processes, providing an efficient solution for a broad variety of applications.

Types of ball mills:

  • Dry ball mill.
  • Grate discharge ball mill.
  • Overflow ball mill.
  • Coal mill.
  • Ball bearing mill.
  • Wet ball mill.
