There are different kinds of aggregate crushers, each used for a specific application. The following table summarizes some of them.
Hammer mill aggregate crusher
A hammer mill aggregate crusher works by impacting the material to break it into aggregate sizes. It consists of a rotating shaft with several hammers attached to it. As the shaft rotates, the hammers hit the material several times to crush it.
Roll Crusher
A roll crusher is a type of aggregate crusher used for producing relatively smaller-sized material. It comprises two parallel rotating rolls positioned horizontally. When uncrushed material is fed between the rolls, they rotate in opposite directions and pull the material into the gap between them. The material gets crushed to smaller sizes between the two rotating rolls.
Gyratory aggregate crushers
A gyratory aggregate crusher is a machine designed to reduce large rocks into smaller gravel, rocks, or stone powder. It works the same way as a cone crusher. The only difference is that a gyratory crusher has a fixed cone and a rotating outer mantle cover. The narrow gap between the cones can be changed to grade the final product size.
Jaw aggregate crushers
A jaw aggregate crusher is a machine used to break down large rocks into smaller pieces. It is used as the primary breaker for hard and tough rocks. The crusher has two vertical plates, one of which is movable. The movable plate exerts pressure on the larger rock pieces to break them into smaller ones.
Impactor aggregate crusher
An impactor aggregate crusher is a machine that uses impact force to break down materials into smaller pieces. It is usually used to process softer stone materials. The crusher has a spinning rotor that throws the material against the surrounding surfaces, which include anvils and scales. The material gets crushed by the high-speed impacts and rebounds of the rotor.
Production capacity
The production capacity is the maximum quantity the crusher can produce each hour. Aggregate crushers with varying production capacities will be available. Smaller crushers may have a production capacity of 20-100 tons per hour, while larger ones can have 1,000 tons per hour or more.
Size range
The sizes of the final aggregate products are indicated by the size range. Aggregate crushers may have different size ranges, producing coarse or fine aggregates. For instance, a crusher may produce aggregate sizes ranging from 0-20 mm, with an additional option for fine aggregates of 0-5 mm.
Types of aggregates
Cement, concrete, natural stones, and plastic aggregates are just a few examples of the diverse types of aggregates that crushers can handle. Depending on the type and model of the aggregate crusher, the types of aggregates that can be processed will vary. For example, some models may crush lighter materials, like bricks or plastics, while others are made for heavy-duty stones or concrete.
Power source
The main power source of a machine indicates whether it is mechanical or hydraulic. Aggregate crushers can be operated manually or via battery.
Regular inspections
Frequent examination of the aggregate crusher is crucial. Components such as the feed system, hopper, and screen should be checked thoroughly. Investigate fasteners to see if they are fully tightened and examine belts and brakes for any wear or tear. This can help spot and address minor issues before they become significant repair requirements.
Lubrication
An aggregate crusher consists of various parts, including bearings, chains, and other moving components that require regular lubrication. Lubricate any parts requiring it as specified in the service manual. Remember to use the proper lubricant for each part to minimize friction and avoid premature component failure and downtime.
Cleanliness
Manufacturers want buyers to maintain their aggregate crushers for longer lifespans and reduce maintenance costs. Keeping the machine clean can also enhance efficiency by ensuring it's free from dirt buildup or debris that may obstruct ventilation or functioning.
There's a wide range of applications for aggregate crushers in different industries. They are primarily used to make building materials in construction projects. However, their use isn't limited to just that. Below is a list of some industries and how they use aggregate crushers:
Construction and Demolition
Aggregate crushers are used to crush concrete, bricks, asphalt, and other construction and demolition materials. The aim is to create recycled aggregates for reuse in construction projects.
Mining
Aggregate crushers break down ore components to extract valuable minerals. The crushed ore is then transported for further processing and refinement to obtain the minerals.
Road Construction
Road builders use aggregate crushers to produce asphalt, base layers, and filter layers for road construction projects. The machines ensure proper compaction and stability of the roads.
Landscaping
Aggregate Crushers are used to produce decorative stones, gravel, and crusher dust for landscaping projects. The materials are used for pathways, driveways, and garden features.
Quarrying
Quarrying machines utilize aggregate crushers to reduce the size of extracted stones and rocks. The crushed materials are then sorted and screened for sale as landscaping stone, construction aggregates, or filler materials.
Recycling Facilities
Aggregate crushers are at recycling facilities to process plastic, glass, metal, and e-waste. The machines reduce the size of the materials and prepare them for separation and recovery of recyclables.
Sand Production
Some aggregate crushers are fitted with sand-producing attachments that allow them to produce sand. The crushers are used to make sand for concrete, mortar, and other applications.
A good starting point when choosing an aggregate crusher for sale is to check the crushing capacity. The crushing capacity gives an excellent indication of how much output consumers will have per unit of time. Many small-scale crushers have a capacity of between 1 to 140 tons per hour. Medium-sized aggregate crushers produce between 500 to 1,000 tons per hour. Large-scale crushers that are used in massive mining sites can have capacities of up to 12,000 tons per hour or more. Keep in mind that a higher capacity typically corresponds to a greater investment, so budget constraints may also come into play during this decision-making process.
Another essential thing to look for when choosing an aggregate crusher is the type of crushing process it uses. A majority of aggregate crushers use impact or cone crushing. Impact crushers work by striking the material being crushed with a high-speed rotor. The material is then further crushed between the blow bars, hammers, and impact walls. This crushing method is used for soft to medium-hard rocks. On the other hand, cone crushers apply a crushing method that is similar to the gyratory crusher. The material being crushed is fed into the top of the cone crusher and is crushed as it moves downwards and narrows. Cone crushers are suitable for hard and abrasive rocks.
When choosing an aggregate crusher for sale, it is essential to check whether the machine has been certified to meet aggregate crusher standards. A crusher that meets industry standards and regulations will have features that enhance the safety of operators and maintenance staff. Such features include lockout/tag-out (LOTO) procedures, which allow employees to isolate the machine during maintenance to prevent accidental start-up. The standards set by the aggregate manufacturing association also ensure that the machine has good air filtration and noise suppression systems that can minimize environmental impact.
Q1: What is the difference between aggregate impact value and aggregate crushing value?
A1: The aggregate impact value gives an idea about the toughness of the aggregate, while the aggregate crushing value determines its strength.
Q2: What is the relationship between the aggregate crusher and the total aggregate crushing value?
A2: The total aggregate crushing value suggests that the sample of the aggregate might be weak. It is determined by dividing the weight of the crushed aggregate by the weight of the uncrushed aggregate.
Q3: Are aggregate crushers market trends?
A3: The demand for the aggregate crusher is expected to increase in the coming years due to the growth of the construction industry worldwide.
Q4: What is the primary purpose of an aggregate crusher?
A4: The main purpose of the aggregate crusher is to crush large rocks into smaller pieces to provide a stable foundation and raw materials for various construction projects.
