Primary crusher works at the beginning of crushing process. So primary crusher usually has larger opening and can crush larger and softer materials. NFLG designs two kinds of primary crushers : JC series jaw crushing plant and PF series impact crusher . Both of these two primary crushers can crush stones with the compression strength below 320MPa.
JC series jaw crusher is the newest Jaw primary crusher which most widely used in primary crushing. This primary crusher absorbs first-class technology from foreign, and develops the technology in the further. The perfect design concept of JC Jaw Crusher makes this types crusher achieve wonderful combination between cost and crushing efficiency. This jaw primay crusher stands to reason that more and more people like to use it, meanwhile, jaw crusher has become more and more widely application. You should believe that our JC Series Jaw Crusher stays ahead of both at home and abroad.
Primay crushing plant
Crushing plant is the primary product of NFLG and you can also call it crusher, stone crusher or rock crusher . As the professional mining equipment manufacturer, NFLG supply the professional crushing plant and crushing solution. Since the day NFLG was founded, we began to supply crushing plant and kept on developing and improving it. Now, NFLG crushing plant is sold to more than 100 countries and areas in the world and welcomed by our customers. NFLG crushing plants include five kinds: jaw crushing plant, cone crushing plant, impact crushing plant, mobile crushing plant and VSI impact crushing plant. We have 15 series of crushing plants totally. Divided from the working part in the crushing process, NFLG crushing plants are divided into primary crusher, secondary crusher and tertiary crusher.
Crushed stone (aggregates) Primary crushing
Trucks with a capacity of up to 50 tons haul rock from where it is blasted and loaded by hydraulic shovels to the primary crusher. For scale note man in the window of the control room (left).
Rocks up to 5 feet by 4 feet by 4 feet in size enter the primary crusher which reduces the size to 12 inches or smaller. Water is sprayed to reduce dust. Water is conserved and recycled in the mining and washing operations.
The primary crusher in this quarry was initially located on the surface. As the quarry was deepened, the primary crusher was relocated to the bottom of the quarry to minimize noise.
The yellow device (left and below) is used to reduce the size of oversize rock so that it will enter the primary crusher. The yellow devise is also used to open ‘rock jams’ in the bin above the narrow opening to the primary crusher. A detail view of rock entering the primary crusher is shown below.
The primary crusher crushes more than 1.5 million tons of stone per year. This is enough crushed stone to make 60 miles of road or 5,000 homes. The primary crusher and related equipment cost several million dollars.
Primary Jaw Crusher Main Features and Benefits
1. Flexible capacity and high reliability.
2. Simple structure and easy maintenance, jaw crusher mainly consists of two jaws.
3. Over-loading protection, jaw crusher has toggle plate to protect it.
4. Stable performance, low operating cost.
5. High crushing ratio which can reach 4-6, also high resistance to friction, abrasion and compression with longer operating life span.
These can range from increased costs due to secondary drilling, blasting and rehandling of rock fragments too big for the crusher, to over-production of troublesome fines that can degrade plant efficiency.
Our jaw crusher employs two oversized hydraulic cylinders behind a traveling toggle beam to make all closed-side setting adjustments — no shims are needed. The crusher’s design provides hydraulic release for overload protection and eliminates the tension rod and spring. The hydraulic system automatically sets the proper tension between the pitman and toggle beam, securing the toggle in place without excessive wear.
Choose the Suitable Primary Crusher
A jaw crusher is generally used as a primary crusher in a crushing circuit. It has higher output by comparing with other crushers. Product is fed into the top of the jaw crusher by a vibrating grizzly feeder .
The eccentric rotating drive shaft causes the movable jaw to oscillate crushing the aggregate against a fixed jaw. jaw crushers are run on belt drives driven by an electric motor or diesel engine. Jaw crushers are used extensively throughout the aggregate and mineral processing industry.
We offer bare jaw crusher units, modular and portable jaw crusher assemblies and entire crushing plants. Contact us for your Primary jaw crushing needs.
PE jaw crusher is the major crushing equipment used as primary crusher in mining and quarrying industry. Our PE series jaw crusher is an economic and practical crushing equipment machine for our clients. The proven PE series jaw crusher is designed to crush even hardest rocks and recycle materials with high crusher availability, low cost per ton, high reduction ratio etc. PE series jaw crusher will be a major crushing equipment in a long time for its excellent performance in more than 100 countries.
