Trimay wear plate and pipe is designed to combat the rigors of high wear environments and is a viable solution to the problem of wear in many industries. By reducing wear, service life of components is extended reducing downtime allowing the user to concentrate on production rather than maintenance and in the process increasing efficiency. Outlined below are some examples of where they can benefit from changing over to using Trimay wear plate in place of more traditional materials.
Cement Manufacture Overview
Cement and concrete manufacturing involves abrasion of the machinery which is brought about by particles from the raw materials. Therefore, it becomes necessary to have a wear protection plan to increase the service life of the machinery. Cement manufacturers make mixtures that incorporate hard abrasive components. The size of the abrasive particles is an important aspect to be kept in mind while coming up with a wear protection solution.
A properly designed plan can maximise the life of the machinery and minimise the frequency of shut downs. Trimay has come up with wear solutions for each stage in cement manufacture, which will be discussed in the subsequent sections. Trimay overlay wear plates find many applications in protection of chutes, deflectors, screeds, hoppers, buckets, conveyors, fan blades, pipe and transitions.
Wear Solution for Quarry to Rawmill
Trimay has devised a step-by-step abrasion protection plan for manufacture of Ordinary Portland Cement. Here we will discuss the first step - quarry to rawmill. In the preparation of rawmix, rocks are crushed at quarries to sizes of 50 mm from boulders of upto 3 to 4 feet. These rocks are mixed in the rawmill till about 5 to 15% of the particles are less than 90 ìm in size.
Key Wear Areas
Primary and Secondary Crusher
In the preparation of the rawmix, the primary and secondary crushers see the maximum amounts of wear. The primary wear mechanism is impact and sliding. The average size of the abrasive particles varies from 1 m to 150 mm. Trimay recommends the T161i, T171* or T170 overlay wear plates for this type of abrasion. For extending the life of the crusher parts, the company suggests simultaneous installation of T170 at all the primary contact points, T156 for the crusher skirts, and T161i on the walls of the crusher.
Haul Truck Boxes
The haul truck and loading buckets and shovels experience a lesser degree of wear as compared to the crushers. They are primarily damaged by the impact and sliding motion of the abrasive particles. The size of the wear particles varies from 1 m to 75 mm. Trimay recommends the use of the T138 or the T171* overlay wear plates for truck boxes and T156 or T171* for buckets and shovels. This protection plan will make sure that the bucket and haul box last longer. Also, in cases where the equipment is required to serve for a period of 5 to 10 years, Trimay suggests the use of T156 or T138 overlay plates.
The primary operation that goes on in the rawmill is the mixing of the rocks; hence it is subjected to sliding abrasion. The wear particles measure more than 90 µm. For protection of the rawmill, Trimay recommends using T156, T161i or T171* over all the primary contact points and T171* or T157 for other lining parts. Parallel installation of T161i on primary contact points and T171* for walls ensures a longer life of the crusher.
Trimay develops and manufactures the highest quality wear overlays for customers seeking to maximize efficiency by extending the life of equipment, parts and pipelines exposed to severe wear conditions. Trimay achieves its high-quality standard through research and development, partner companies and exclusive suppliers, as well as through in- house experimentation and process optimization.
