Plant maintenance and shutdown planning
The key to successful plant maintenance shutdowns is planning. As the mill reline work is often the critical path task on a shutdown, Pacific Relines develops a detailed plan for each project to maximise the effectiveness of available resources to minimise total project time.
This plan is presented to the principal for examination and comment in the lead-up to the project and a detailed report is presented to the principal upon the completion of each project. Progress outcomes, safety issues and recommendations for future projects are covered in the completion report.
Remote area and rapid mobilisation specialists
Pacific Relines is a remote area mill reline specialist, supplying maintenance and shutdown services to regional mining sites nationally and internationally. Pacific Relines has unrivalled experience and expertise in the logistics of mobilising our specialised reline crews to an operation for scheduled and unscheduled maintenance.
Pacific Relines operates our own company aircraft, providing valuable flexibility and an ability to mobilise direct to site and at short notice if required.
Safe grinding mill reline services
Pacific Relines considers the occupational health and safety of all personnel associated with our operations to be of the utmost importance in the conduct of our business. With our objective of zero harm, we have consistently improved our performance by reducing injuries in the workplace.
To that end, we have a documented safety management system in place that covers the specific requirements of mill maintenance as well as more general areas of plant maintenance. Safety systems are certified to AS / NZS 4801:2001.
Accredited mill reline specialists
Pacific Relines personnel have many years of experience in the delivery of mill relining. We have senior crew members with extensive experience spaning mines, installation, mechanical and civil works for the utilities industry, some of whom have in excess of 15 years’ experience with the company.

Brief Introduction Granite crusher
Granite crusher is widely used in multitudinous departments, such as mining, metallurgical industry, building material, highway, railway, water conservancy industry and chemical industries. It could deal with materials which has a length within 100-500 millimeters. Its maximum compressive strength could reach 350 mpa. And it has many advantages such as bigger crushing ratio, the broken materials could turn into cube particle etc.
Usage and usable range
Granite crusher is widely used in crushing and reshaping of hard materials which coud be applied in mining, sand market, water conservancy and hydropower, highway, railway, chemical industry and building materials industries, such as: basalt, granite, cobble, limestone, concrete, etc.
Granite crusher could deal with materials which length is within 100-500 millimeters. Its maximum compressive strength could reach 350 mpa. And it has many advantages such as bigger crushing ratio, the broken materials could turn into cube particle etc.
Granite Crusher Working principles
Granite crusher is a kind of crushing equipment which could break materials by impact. When the material is going into the function area of plate hammer, the broken materials will be constantly thrown back onto the counterattack device installed above the rotor with the high-speed impact of plate hammer.
Then they will be striked back by scaleboard to the function area of plate hammer and will be striked back again. After that, the materials could be processed again in crushing cavity. The materials will be discharged from the bottom of the machine until the materials are crushed into certain particl size.
Characteristics of function
Granite crusher has a simple structure without key links and a unique counterattack lining board. Hard rock broken function is very efficient and its energy consumption is lower. Its products are in the shape of cube, the size of discharging is adjustable, and has a simplified crushing process which economize the production cost.
Structure characteristics of Granite crusher
1. The machine has a bigger feeding port, higher crushing cavity, and suit with harder materials. The product has better lumpiness and less mountain flour.
2. The clearance between counterattack plate and plate hammer coulf be adjusted conveniently to control the particle size, the particle shape is better;
3. The machine has a compact structure, strong rigidity. The rotor inertia is larger.
4. High chrome plate hammer has a higher impact resistance, abrasion resistance and the force of impact is huge;
5. The machine has no key links which enables its maintenance more conveniently, economical and reliable;
6. The machine has complete crushing function, higher productivity, smaller machine abrasion rate, higher comprehensive benefits.

For economic reasons alone, the growing demand for basic raw materials such as ores, coal, salts and the like calls for extraction methods where an undesirably large percentage of deads is obtained as well. These contaminants require preparation of the extracted crude products, e.g. in preparation for smelting, as a substitute for household coal and power plants or as basic material for processing in various industry sectors.
Coal, for instance, must be graded according to grain sizes and rid from rocks (refuse) in separating plants. Ores must first be finely ground and then graded; salts musts be ground and graded. in some cases screen grading is sufficient for upgrading a given material.
Grading means separating solid matter according to grain size. In screen grading, the material is separated mechanically on screen plates. Extremely fine grains of less than 1 mm are primarily separated by means of air separation. In this process, an air current supersedes, in a way, the screen plates. in hydrograding (sizing in a flow of water) the different grain sizes are separaten in a flow of water.
Both in hydrograding and in air separation, variations in density and grain shape reduce the accuracy of separation. Over the past three decades, there has been enormous technical progress in the separation of materials according to grain size. The sizes of the machines used for grading, classifying and centrifuging were rapidly increased into ranges which were not considered safely feasible before.
Until far into the sixties, the maximum permissible width of these vibrating screens, which dictates their performance, was about 2.50 m. However, economic considerations led to the development of bigger, safer and easier-to-maintain vibrating machines with the objective to process both dry and moist materials, achieving the highest possible specific throughputs and the best possible accuracy of separation. Today, operationally reliable vibrating screens are up to 5.50 m wide and feature an active screen surface of approx. 40 to 45 m2 on a single tier.
The vibrating screens needed for the various grading jobs are among the most severe bearing mountings encountered in the processing technology sector. Due to the permanent alternating stress to which all machine components are exposed, and the dangerousness of their auto vibration, there was only a gradual development toward larger machines.
Rolling bearings in vibrating screens are stressed by high, mostly shock-type, loads. To compound matters, the bearings, while rotating about their own axis, perform a circular, elliptical or linear motion. This results in high radial accelerations which additionally stress the bearing, and especially the cage.
The operating speeds are usually very high so that the bearing temperatures in vibrating screen applications are 20 to 30 K higher than in normal applications.
Moreover, in screening machines, major bearing misalignments and pronounced shaft deflections must almost always be reckoned with.

Working principle of broken glass
Glass crusher machine
Large piece of glass from the machine into the upper part of the vertical high-speed rotation of the impeller at high speed under the effect of centrifugal force, and the other part of the umbrella in the form of materials diverted around the impeller produces high-speed impact and crushing, the material after impact each other, will in between the impeller and the casing to form a vortex several times each material impact, friction and grinding, through discharge from the bottom to form a closed loop several times, controlled by the screening equipment to the required product size.

(1) simple structure and reasonable operating costs low. Stone by stone at the principle of wear.
(2) crushing rate, energy saving.
(3) has the crushing, coarse grinding function.
(4) The moisture content of materials subject to little effect, moisture content of up to 8%.
