At the primary stage, large scalping screens remove fine material before the feed enters the primary crusher, helping to protect the crusher's wear parts from abrasive stone or sand material that has already been sized. Without scalping, the primary crusher's liners wear faster, requiring more frequent changes and maintenance downtime.
Crushing plant layout differs a great deal from site to site. Plants are designed differently due to variation in the type of rock, the use of the products, the size of the quarry, plant history and many other factors. The plant model is formed by connecting the various production unit models to each other.

Discover the best practices for designing a successful stone crusher plant, including factors to consider, equipment selection and configuration, environmental management, and safety and maintenance priorities. Learn how to optimize crushing operations and minimize environmental impact for efficient and effective production.
Many modern impact crusher installations have a variable speed drive arrangement that allows an increase in the rotor speed to compensate for wear on the impact hammers. In many impact crushers, a third curtain or crushing chamber can be added to increase reduction in every pass through the machine.
A daily morning walk-around establishes a good baseline for crusher performance. {{image2-a:c-w:400}} {{image5-a:l-w:100}} 2. THE PEER-IN. Looking into the crushing chamber through the inspection hatches on the feed hopper is a simple way to identify non-crushable items that might have entered the crushing chamber.
This allows quarry operators to meet the demands and expectations of customers and, in turn, provide quality service. Maintenance includes adjustments, cleaning, lubrication and parts replacement. Not only will regular plant inspections and maintenance improve plant performance but it will also help the quarry operator …
Except star, stop and daily maintenance, the equipment doesn't need much labor operation. Combined with electric control system, the whole operation of the equipment is reliable, convenient and energy-saving. Stable performance; Quarry crushing plant has large crushing rate, strong production capacity, easy maintenance, long service life.
Primary impactors should be of a solid rotor-type to reduce maintenance costs. Impactors should have a connected wattage sufficient to ensure 110 per cent utilisation. Crusher applications, speed and setting are the factors affecting this. Impactors should be consistently fed, based on the amperage drawn.
MOBILE CRUSHERS Some operations do not require mobility, since the projected life of the quarry will be decades. In such cases, stationary crushers are put in place, offering a custom-built, heavy-duty design. However, most contractors require highly mobile machines that can be easily dismantled and moved from one site or job to another.
The type of plant selected will generally depend on how long the reserves will last. There are basically three types of plants. Stationary plant: This type of plant is generally associated with quarried materials where the expected life of the quarry is more than 10 years. It should also be noted that large sand-and-gravel plants will fall into ...
