1.Cone Crusher Working Principle And Wear Parts Definition

Cone Crusher Working Principle

Rock is fed into a large opening at the top of the cone crusher where it is squeezed between the mantle and the cone. As the size of the rock decreases, pieces fall into lower levels of the crusher where they continue to be worn and broken down further. Once small enough, the fragments of rock exit through a narrow opening at the base of the machine. Cone crushers manipulate rock between a fixed cone and the movable cone (the central shaft). The width of the exit opening is adjustable through ascending and descending the fixed cone which allows the rock to be crushed to a variety of sizes.

Wear Parts Definition

Mantle: Covers the cone head of the crusher to protect it from wear. It is the inner sacrificial wear liner that sits on the cone head.

Concave: Sits in the upper frame of the crusher to protect it from wear. It is the outer sacrificial wear liner that sits inside the upper frame.

2.Material Selection For Cone Crusher Wear Parts

Different crushed stones or ores need to choose the different materials to suit. There are some materials for cone crusher wear parts:

Mn14Cr2 Steel

Mn14cr2 mantles and concaves are used in crushing soft stone. For example, it has a good life when crushing the easy and non-abrasive blasted rock, non-abrasive gravel, and non-abrasive round rock.

Mn18Cr2 Steel

Mn18Cr2 is the most popular material for casting cone crusher mantles and concaves. This Mn18Cr2 mantles and concaves widely in crushing difficult and non-abrasive blasted rock, medium and non-abrasive,non-abrasive gravel, and non-abrasive round rock.

Mn22Cr2 Steel

Mn22Cr2 mantles and concaves are widely used in crushing hard and abrasive stone.

TIC Inserts Alloy Steel

This material is designed by Qiming Machinery. We use titanium carbide rods to insert the working surface to help customers to get longer life. Compare with normal manganese cone crusher liner, our TIC insert wear parts span life can be 2-3 times. Based on our customer feedback, the more hard material to crush, the long span life.

Manganese Alloy Steel

This material is also designed by Qiming Machinery for our copper mine customers. We use manganese steel as the body material, and add some rare elements to get more wearable parts.

3.Popular Cone Crusher Cavity Types

Crush different materials need different cone crusher cavities. The suitable cavities will help you get more profit and crush more material. Normally, there are six kinds of cone crusher mantles and concaves types:

  • Standard
  • Medium
  • Fine
  • Coarse
  • Extra Coarse
  • Extra Fine

A wide range of liners are available to accommodate coarse and fine feeds, but which you choose depends on several factors. The most important factor in Cone Crusher liner selection is the feed.

Cone Crusher Cavity Types

Cone Crusher Cavity Types

You should have a well-graded feed going into the crushing chamber. A well-graded feed is generally considered as:

  • 90-100% passing the closed-side feed opening. Some people look at 80% of the open side as well and select the smaller of the two.
  • 40-60% passing the midpoint.
  • 0-10% passing the closed-side setting.

You want to match the entire feed gradation, not just the feed size, so that you utilize the entire chamber. It is important to utilize as much of the crushing chamber as possible to get the required reduction and desired throughput.

Plant feed size and the output from your previous crushing stage defines your top feed size, which will give the maximum cavity opening. The cavity opening should not be too big in relation to the top feed size. Cavity openings that are much larger than the feed size leads to poorly utilized reduction and liners.

If the feed size is too small, the majority of the crushing takes place in the lowest portion of the cavity, which means the bottom of the liners will wear away faster than the top of the liners. The production will decrease due to the poor reduction ratio. The power limit of the crusher will be exceeded at a minimal volume level, and you’ll run the risk of improper bearing alignment.

Most of the wear on crusher liners occurs right before the parallel zone (the smallest space between the mantle and the concaves where the final crushing takes place), but this wear will be accentuated if the feed is too small, and you’ll end up with a bowled-out pocket before the parallel zone way too soon.

On the other hand, if the feed size is too coarse, the feed material will keep percolating around the feed opening, causing the top of the liners to wear away faster. Because the feed opening is bridged over, throughput is reduced and production decreases. The output gradation will be coarser, and the product will be slabby, not cubical. The volume limit will be exceeded at minimal power draw.

Understanding your gradation going into the crusher helps you to choose the right liner configuration necessary to achieve your production goals. The right liner selection gives you a better nip and more room to adjust other parameters, such as the closed-side setting.

Flow Chart

Cone Crusher Wear Parts Production Process

Cone crusher wear parts choose sand casting and V-method to cast them. Its flow charts as following steps:

  1. Pattern making.
  2. Pattern painting and flask molding.
  3. Choose the right raw material.
  4. Bottom pour ladle casting.
  5. Cooling, Moulding box open, and sand conditioning.
  6. Cleaning.
  7. Heat treatment.
  8. Polishing, Machining, QA Checking.
  9. Painting and Shipping.

5. How to choose the right cone crusher wear parts manufacturer?

In order to find the right cone crusher wear parts manufacturer, there are some things need notices:

  1. Because of all of the cone crusher wear parts are manufactured by manganese steel or manganese alloy steel, so we need to find some manganese steel foundries;
  2. Check the foundry if have the inquiry parts patterns;
  3. Check which casting method the foundry use;
  4. Check which kind of sand the foundry uses to make sand mold,Olive sand or Resin sand;
  5. Check if the foundry has a casting operation manual and traceability records;
  6. Check if the foundry supplies all quality control reports, which include size report, material report, mechanical behavior report, and dye inspection.
