The Comparasion of Two Kinds of Crushing Process
Stone production lines are divided into two types, gravel production line and sand production line. Of course, if the classification is different, the equipment configuration for production line must be different. The main equipments of gravel production line is crushing devices, but for sand production line it is making sand equipments. According to the hardness of the broken materials, the stone production line can be divided into one-step forming and secondary crushing stone production line. And sand production line is combined by vibrating feeder, jaw crusher, sand making machine, vibrating screen and rubber belt conveyer equipment etc.
Sand and tone production line is named by the output material type,and the finished include stone and manual sand.It is the same to the combination of stone production line and sand production line.In the factory that manufacture material for building roads and buildings,the sand stone production line is needed.This kind production line can meet the requirement of producing stone and sand at the same time.
The main flow chart of the stone production line main includes:hopper-vibrating feeder-impact crusher-vibrating screen-finished product,each equipment is combined by spiral chute and be;t conveyor.
1.the basic flow chart of sand stone production line:
The vibrating feeder feed the stone to the jaw crusher for coarse crushing,then the output material are sent to the impact crusher by belt conveyor for further crushing.After that,the material are sent to the vibrating feeder for screening,the finished product which can meet the size requirement will be sent to the sand washing machine,the material come from the sand washing machine are the final finished product.
2.The performance of sand stone production line
This sand stone production line has high degree of automation,and the operation cost is low,and it is also with features of energy saving,high production,little waste and easy maintance.The sand stone production line is designed according to the use of the finished product. As each equipment combines reasonably,the production line cover small area,and the investment efficiency is high.
Large stone via feed bin evenly is sent into jaw crusher by vibrating feeder for coarse crushing, the broken stone is conveyed by belt conveyor to counterattack crusher for further broken. The fine stone is delivered by belt conveyor into the vibrating screen for screening to several different specifications. The stone that meets the size requirement will be transmitted to the finished stone pile by belt conveyer of finished products. The stone that doesn’t satisfy the granularity request will be reverted to impact crusher by belt conveyor for crushing again. It forms a closed-circuit repeated broken circulation. The granularity of finished product can be combined and classified according to user’s requirements. For the protection of environment, it can be equipped with auxiliary dust removal equipment.

More impact crusher effects product fineness much
Gold mining equipment solution. Mining gold is a complexed progress. In order to get gold, we must crush the gold ore. So we need crushers. Jaw crusher is the most common crusher of gold mining equipments. South Africa is the country that is abound in gold ore.
Safedem conducted several trials to determine the most efficient way of dealing with this concrete monster. First, excavator-mounted hydraulic breakers were tried out, but it quickly became clear that mechanical demolition on its own would not meet the challenge.
The company vertical impact crusher and Steel impact crusher is characterized by great reduction ratio, high reduction efficiency, convenient maintenance, etc. The final product is in the shape of a cube. Safedem then decided to trial explosive blasting followed by mechanical demolition. A number of 30 mm (1.2 in) diameter holes were drilled in a 1 m (3.3 ft) centre grid formation over areas up to 100 m2 (1,076 ft2), drilled to a depth of 2.2 m (7.2 ft) into the top three concrete layers of the roof.
Because of the very heavy reinforcement in the concrete, this proved difficult and expensive due to breakage of drill rods and the high wear factor of drill bits. During trial blasting, seismic monitoring was carried out to determine air over pressure and vibration levels. Various locations across the site were selected for this monitoring and in particular at positions immediately adjacent to the nearby residential homes. From the results, Safedem agreed with the local authority that the maximum weight of charge for each future blast would not exceed 25 kg (55 lb).

Operation and maintenance of the hammer crusher
Hammer crusher is applied to crushing medium hard and weak corrosive materials as jaw crusher. Hammer crusher crushes materials mainly by the shock effect to the materials. The broken materials obtain kinetic energy from the hammer, and then run toward the baffles, sieve article. At the same time, materials impact each other, and been repeatedly broken, some of the materials discharged from the gap of the sieve article, and some bigger materials will be impacted, grinded again by the hammer, and become the products with required granularity.Disadvantages of the hammer crusher: The hammer and the sieve article wear easily, especially crushing hard materials. When crushing sticky materials, the sieve article will be stocked by the materials, and will cause downtime. So the moisture of the material should not exceed 15%.
The hammer crusher is a simple machine to operate. It has a simple ON/OFF operation and reset feature in the event that the latch is opened while running or thermal overloads trip. However, as with all machines there are other things to consider before operating.
The inside of the machine is free of paint in order to prevent ongoing contamination of samples. However, there is a light coating of rust preventative present. Initial samples will wear this coating off and leave a bare metal surface that will not affect your sample.
Refer to you lab policies on the number of discard samples that should be run before using the machine for test readings.
Hammer crusher crushes the materials through the high speed rotating hammer. Then the installment of basic and rotating axial must be horizontal, the length ways error is less than 0.5/1000mm, the axial error is less than 0.1/1000mm;
Hammer crusher crushes the materials through the high speed rotating hammer. Then the installment of basic and rotating axial must be horizontal, the lengthways error is less than 0.5/1000mm, the axial error is less than 0.1/1000mm;
Crushers for fine and medium crushing are designed with reverse operation of the rotor and hammers. The design of the inlet chamber, rotor with staggered hammers and smooth grate surface have a favorable influence on thecrusher capacity. The design of the crusher housing (its tipping part) allows simple and quick access to important parts of the crusher for maintenance.The impact crusher can be rearranged either in a closed path or in an open path. The machine can be supplied with a common base frame for the crusher and drive which shortens the installation time of the crusher. The frame can be supplied with a flexible seating to reduce the dynamic forces on the foundations.
