The mining industry in Zimbabwe is a significant contributor to the country's economy. The mining industry in Zimbabwe accounts for over 60% of exports in the country. Having a terrain that is quite similar to Australia and Canada, the country is a producer of many minerals and metals. Zimbabwe is particularly known for its resources of platinum group of mineralsas well as nickel, gold, diamonds and others.

Zimbabwes mining industry is focused on a diverse range of small to medium mining operations. The most important minerals produced by Zimbabwe include gold, asbestos, chromite, coal and base metals. The mining industry contributes approximately 8% towards the countrys GDP.

The first step of the mining and mineral processing operations is to remove the mineral value in ore from the host rock or matrix. Minerals may be extracted from the earth using a variety of techniques. Most extraction processes result in the removal of ore and associated rock or matrix in bulkform from the deposit, using blasting and crushing operations to break the ore into pieces of manageable size or to separate the ore minerals from unwanted material.

Mining operation involves many different types of machines. As referred, there are many small and medium mining operations in Zimbabwe; mining technology is still in developing. It requires high technology and quality mining equipment to develop mining industry in Zimbabwe. Crusher machine is one of integral equipment in mining industry. SBM provides high performance and low price crusher for mining industry in Zimbabwe.

Different scale of mining operations has various investment capacities and requires different types of mining machines.In mining operation, crushing is the first the integral operation, the layout of mineral crushing plants is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.

There are many factors to be considered for designing a reasonable crushing plant, such as ore characteristics, mineral deposit location, climatic conditions, expected operational life, safety, environment, and operability and maintainability. There are three main steps in designing a good crushing plant: process design, equipment selection, and layout.

With the development of quarrying and mining industries, various new types of mining equipment are designed for different applications. Nowadays, tracked mobile mineral crushing equipment has been gradually replaced stationary crushing plants.The main benefits of mobile crushing plants is their optimized flexibility, maximized productivity and minimized operating costs,meantime increasing safety and reducing environmental impact.

As ore grades decline at mines worldwide, more ore needs to be processed to obtain the same amount of the valuable contained mineral and to meet production targets. This often results in increased processing costs and can prove problematic for miners. Metso said it is responding to this challenge by developing larger, more energy-efficient equipment for minerals processing. One example of this effort is the MP2500, billed as the worlds largest cone crusher, two of which will be installed at First Quantum Minerals Ltd.s Sentinel copper mine in Zambia. The installation is scheduled to be fully operational in early 2015, under a contract valued at 10 million euros received in 2013.

Metso said the MP2500 was selected for Sentinel because it can process large volumes of rock as a single machine. It saves costs as fewer crushers, related infrastructure and maintenance are needed for achieving the same or increased amount of production. According to the company, the MP2500 crusher has the largest feed opening ever offered in this type of crusher, enabling it to accept bigger chunks of rock than traditional crushers and decreasing energy consumption in the comminution process.

MP2500s are designed for use in secondary and tertiary crushing and, according to the company, can be linked with other Metso products to create a simplified, cost-effective process flow for high-production sites. For example, in order to duplicate the performance of two MP2500s, four of its 1,250-hp MP1250 crushers and associated infrastructure would be necessary. At Sentinel, the new cone crushers will be part of the secondary crushing circuit installed to maintain mill throughput in the face of harder ore being mined in the deeper areas of the pit. According to Metso, depending on the ore characteristics and SAG efficiency, the MP2500s could provide a throughout range of 3,0004,500 metric tons per hour (mt/h).

Development of the MP2500 represents a number of innovations in the area of health and safetysome based on discussions with FQML, according to Metso, perhaps the most significant is there is simply less equipment needed to be installed at the site, resulting in reduced maintenance activity.

Serviceability and ease of maintenance was also a focus during the design. Because of the size of the equipment, Metso had to develop a new method (patent pending) to remove the crushers socket that eliminated heating of the part in a difficult working space. This method also eliminates process variables associated with socket removal and reduces the overall stress on both the socket and main shaft. Metso also refined the existing jackbolt locknut design to reduce the amount of manual work necessary, adding hydraulics to simplify the process.

Metso said it is assisting the mine to guarantee efficient operation of the new crusher by stationing full-time field service engineers on-site for one year after commissioning and by stocking critical spare parts in Metsos distribution center in South Africa as well as on-site.

Eastman is a typical direct selling enterprise with green and standardized production plants. All the delivery of the equipment will be completed within the delivery period signed by the contract to ensure the smooth commissioning of the equipment.

Rock crushers have a wide range of suitable material to choose from, whether its soft or hard, or even very hard, rock crushers can reduce those large rocks into smaller rocks, gravel, or even rock dust.Here are some typical materials that break or compress by industry crushers, such as Granite, quartz stone, river pebble, limestone, calcite, concrete, dolomite, iron ore, silicon ore, basalt and other mines, rocks and slag.

Understanding the stages of crushing process and the types of crushers that best fit each stage can simplifies your equipment selection. Each type of crusher is different and used to achieve a certain end result.

Similarly, a certain output is expected at the end of each crushing stage for the next phase of the process. Aggregate producers who pair the correct crusher to the correct stage will be the most efficient and, in turn, the most profitable.

A jaw crusher is a compression type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The discharge size is controlled by the setting or the space between those two pieces of steel. The tighter the setting, the smaller the output size and the lower the throughput capacity.

As a compression crusher, jaw crushers generally produce the coarsest material because they break the rock by the natural inherent lines of weakness. Jaw crushers are an excellent primary crusher when used to prepare rock for subsequent processing stages.

Although the chamber is round in shape, the moving piece of steel is not meant to rotate. Instead, a wedge is driven around to create compression on one side of the chamber and discharge opening on the opposite side. Cone crushers are used in secondary and tertiary roles as an alternative to impact crushers when shape is an important requirement, but the proportion of fines produced needs to be minimized.

An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher with the rotating blow bars or hammers in the rotor. The secondary breakage occurs as the material is accelerated into the stationary aprons or breaker plates.

Impact crushers tend to be used where shape is a critical requirement and the feed material is not very abrasive. The crushing action of an impact crusher breaks a rock along natural cleavage planes, giving rise to better product quality in terms of shape.

Most aggregate producers are well acquainted with the selection of crushing equipment and know it is possible to select a piece of equipment based solely on spec sheets and gradation calculations. Still, theoretical conclusions must always be weighed against practical experience regarding the material at hand and of the operational, maintenance and economical aspects of different solutions.

The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker could also be the best choice.

The most important characteristics of a primary crusher are the capacity and the ability to accept raw material without blockages. A large primary crusher is more expensive to purchase than a smaller machine. For this reason, investment cost calculations for primary crushers are weighed against the costs of blasting raw material to a smaller size.

A pit-portable primary crusher can be an economically sound solution in cases where the producer is crushing at the quarry face. In modern plants, it is often advantageous to use a moveable primary crusher so it can follow the movement of the face where raw material is extracted.

The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important.

In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing. In most cases, the objective is to obtain the greatest possible reduction at the lowest possible cost.

In most cases, the fine crushing and cubicization functions are combined in a single crushing stage. The selection of a crusher for tertiary crushing calls for both practical experience and theoretical know-how. This is where producers should be sure to call in an experienced applications specialist to make sure a system is properly engineered.
