best selling jaw crusher for stone processing

Jintai crusher plant with world-class manufacturing processes, most high-end production of materials, more advanced dynamic jaw bearing, adjusting shim is more simple, safe and fast, crusher plant with higher bearing capacity, the effective labyrinth seal and the bearing service life is greatly prolonged; at the same time, crusher plant low noise in operation, less dust, for economic development brought great benefits, and successfully promoted the urban low carbon economy high speed development, crusher plant has brought great benefit for customers.

In the production line of sand and stone, crusher plant is the best choice, most of the gravel production enterprises in the middle size of stone crushing will choose crusher plant equipment.

JINTAI crusher plant machine is composed of two jaw plates of the moving jaw and the static jaw plate, which is a crushing machine for simulating the movement of the animals.

crusher plant is widely used in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industries in various ores and large blocks of material crushing. 

JINTAI crusher plant in the mining, building materials, infrastructure and other sectors mainly used for coarse crushing and grinding machine. crusher plant in accordance with the feeding port width size to points for large, medium and small three, feed outlet width of more than 600mm for large crusher plant, feeding port width in 300-600MM for medium-sized crusher plant, feeding port width less than 300mm for small jaw type crusher. crusher plant is simple in structure and easy to operate. The series of product specifications complete, is the first choice of broken equipment.

crusher plant features

1, low noise, less dust.

2, its crushing ratio, uniform product size.

3, crusher plant structure is simple, reliable operation, low operating costs.

4, crusher plant lubrication system is safe and reliable, easy replacement parts, equipment maintenance is simple.

5, crusher plant broken cavity depth, improve the feeding capacity and output.

6, equipment energy saving

7, crusher plant high flexibility : gasket type discharge port adjustment device, reliable and convenient, large adjustment range, increase the flexibility of the equipment; discharge port adjustment range, can meet the requirements of different users

JINTAI crusher plant  has the function of environmental protection, in addition to reducing the environmental pollution caused by the external waste, the crusher plant to the environmental pollution degree to the lowest. Because the crusher plant will produce a lot of dust when it is broken, so the sealing performance of the crusher is higher. We can also seal the internal installation of dust removal equipment at the same time, so that we can basically solve the problem of dust leakage.

crusher plant application range:

crusher plant can crush sand and stone field, mining, coal mining, concrete mixing station, dry powder mortar, power plant desulfurization, quartz sand, etc.
crusher plant application materials: gravel, granite, basalt, iron ore, limestone, quartz rock, diabase, iron mine, gold mine, copper mine and other

Structure of crusher plant
The structure of crusher plant is mainly composed of a machine frame, an eccentric shaft, a big belt wheel, a flywheel, a movable jaw, a side guard plate, an elbow plate, a back seat of the elbow plate, an adjusting screw, a return spring, a fixed jaw plate and a movable jaw plate. The elbow plate also plays the role of insurance; the eccentric shaft through the frame structure; flywheel and eccentric support bearings, often using spherical roller bearings, resulting in eccentric motion. The crusher plant working environment of the bearing is extremely harsh, bearing must be subjected to the huge impact load, abrasive and high temperature wastewater. From here it appears that the bearing of the crusher is very important, in the selection of the crusher must be sure to ensure the quality of the bearing and after-sales service.

Main parts of crusher plant
1 rack

crusher plant frame is the upper opening and the lower opening of the walls of the rigid frame, used as supporting the eccentric shaft and bearing broken materials for the reaction, the request have sufficient strength and rigidity, generally with the integral cast steel casting, small jaw type crusher also available high-quality iron instead of cast steel. Large crusher plant frame to segment cast, and bolt firmly linked into the whole complex casting process.
The frame of the self-made small crusher plant can also be welded by thick steel plate.
2 crusher plant plate and side guard
The fixed jaw and the movable jaw of the crusher plant are composed of the jaw bed and the jaw plate. The jaw plate is the working part and is fixed on the jaw by the bolt and the wedge iron. The jaw of the fixed jaw is the front wall of the machine frame, and the movable jaw is suspended on a week to have sufficient strength and rigidity to withstand the crushing reaction force, which is mostly cast steel or cast iron.
3 transmission parts
The eccentric shaft of the crusher plant is the main shaft of the crusher, which is made of high carbon steel. Eccentric parts to be processed, heat treatment. One end of the eccentric shaft is provided with a belt wheel, and the other end is provided with a flywheel.

Working principle of crusher plant:
The crushing mode of the crusher plant is the curve type. Motor drive belt and belt wheel, then the movable jaw movement down by the eccentric shaft; when the movable jaw rises, the toggle plate and dynamic jaw angle becomes larger, which pushes the movable jaw plate close to the fixed jaw plate, and the material is extruded, rubbing, grinding and other multiple broken; when the movable jaw downward, the toggle plate and movable jaw angle becomes small, jaw plate in under the action of the pull rod, a spring is scheduled to leave the jaw plate, has been broken material from the crushing cavity mouth eduction, along with a broken motor e periodic crushing and discharging to achieve mass production.

Description of the use of crusher plant
(a) preparatory work

1, should carefully check the lubrication of crusher plant bearings, bearing inner elbow plate connection is sufficient to grease.

2, should carefully check the crusher plant all the fasteners are fully tightened.

3, the protective device is good, found unsafe phenomenon, should be immediately eliminated.

4, check the broken cavity of the ore or other debris, if have, immediate elimination.
(b) start

1, after inspection, proof crusher plant and drive part of the normal situation before you can start.

2, crusher plant can only start in the case of no load.

3, after starting, if the crusher plant has not normal circumstances, should immediately stop, to identify the reasons for the exclusion of hidden dangers, can once again start.
(c) maintenance and use

1, after the normal operation of the crusher then feeding.

2, to be broken material should be evenly into the broken cavity, and should avoid the side feeding, to prevent the sudden increase in load or sudden change.

3, under normal circumstances, the crusher plant bearing temperature rise should not exceed 35 degrees, the maximum temperature shall not exceed 70 degrees, or should immediately stop, identify the reasons and elimination.
(d) lubrication

1. Always pay attention to the lubrication of the friction surface of the crusher plant in time, which can guarantee the normal operation of the machine and prolong the service life.

2, the machine uses the grease, should be based on the use of location, temperature and other conditions to decide, generally can be used calcium, sodium or calcium sodium base grease.

3, join the bearing seat of the lubricating grease for the volume of 70% - three, must be replaced every 50 months; for new oil must be cleaned with a clean gasoline or kerosene bearings and bearing seat inside the dirt.

4, before starting, elbow plate and elbow pad contact must join the grease.

The package of crusher plant standard container, spare parts will be packed in wooden cases.
