Small crushers are usually used to crush solid samples in laboratory, but how can we choose suitable ones?
1. Crushers for High humidity solid materials
We have tested and find that hammer crusher can crush materials with moisture content less than 25%, while jaw crusher can crush materials with moisture content less than15%.
hammer crusher is more suitable to crush high humidity solid materials
2. Working Efficiency
We will use a jaw crusher and hammer crusher with the same inlet size to test, the materials we used is around 25mm, we will set the output size as 5mm.
Materials are put in the crushers by a mini belt conveyor, jaw crusher can produce 2 tons per hour while hammer crusher
can produce 500kg. Even the crushing ratio of jaw crusher is about 60%, it is more efficient than hammer crusher.
3. Evenness of final product
Crushing ratio of jaw crusher is 60% while hammer crusher is 100%. Hammer crusher is better to get evenly final product
4. Feeding size
To compare the capacity of hammer crusher and jaw crusher with same inlet size. The biggest materials jaw crusher can crush is 80mm, but hammer crusher can only crush materials smaller than 30mm.
5. Finest output size
Distance between the jaw place can not be smaller than 2mm, or else they are easy to bump each other, what is more, the big materials may block the outlet. The finest size jaw crusher can do is around 4mm.
The output size of hammer crusher is depend on the sieve plate. The finest sieve hole is 1mm. That is to say, final product bigger than 1mm can not get out of the crusher and will be recrushed.
Hammer crusher is better than jaw crusher in fine crushing.

The slag mainly consists of calcium, iron, silicon, magnesium and a small amount of aluminum, manganese, phosphorus and other oxides. In some areas, the slag also contains little titanium and vanadium because of the ore containing those ingredients. Slags are greatly different due to the various components in steel-making furnace, steel furnace steel smelting and each different stage of the smelting process. The application of the crusher has brought new hope to the slag processing.
The approach to dealing with the slag uses the slag and the primary slag as raw materials. The processing technology includes cold abandoned method; hot pour method, splashing cold plate method, water quenching method. Generally, it uses a closed loop production process which is respectively composed by the process of crushing and screening, vacuum ball milling, classification and wind dry magnetic separation to receive four high-quality and high value-added products, which namely means that the steel scrap with a iron content greater than 90 % of high-quality can be used for high-grade iron powder iron that can be used as a cement and concrete admixture of high activity for high-grade steel slag powder and the road surface of asphalt concrete surface layer of steel slag aggregate. After the entire production process completed, it can achieve zero emissions slag with no pollution.
We all know that the highway requires much higher to a variety of raw material. As the most basic raw materials, river gravel with hard, stable nature and excellent grain shape is preferred. River pebbles Symons cone crusher can do further processing to river pebbles, it do not necessarily to destroy the chemical characteristics of river pebble for excellent grain type. Gathered black sand in river pebbles, and the pebbles should account for more than half of the volume. As river pebbles are more common to us and good in appearance, it has become an ideal choice for paving courtyards, roads and construction.
Because stone hardness is demanded much more, the new advanced cone crusher drives crusher industry and leads the bright market prospects.
Building sand and stone is necessary building materials in the construction of roads, railways, docks, airports and nuclear power, etc. And the start of each new project requires several or even dozens of various types of rock mine to match with. It is understood that China plans to build 153 thousand kilometers at length highway, but so far the national highway is 65,000 kilometers, only about 40% of the whole plan. The railway in 2010, China railway investment has been arranged fixed assets for 823.5 billion RMB, of which 700 billion RMB was in capital construction. The two data have growth of 37% and 17% respectively compared with 2009. Railway construction is also in a period of rapid development.
Both processes of crushing and grinding are suitable for the mineral particle size of more than 5cm, which is before ore dressing process flow. And crushing process mainly handles large pieces of ore. Grinding treatment is especially for smaller mineral particles. Because mineral particles in the ball mill was broken at random, the broken probability is very low, studies have shown that the broken probability is less than 10% in the ball mill.
Roads and railways built can’t be separated from the sand and gravel aggregate, the demand for sand and gravel production line has increased. Sand and gravel production line is generally composed by the feeder,and centrally electric control devices. The process is reasonable and gathering feeding, crushing, screening, conveying as a whole. After processed, the finished product quality can be up to GB14685-2001 standard, which is qualified for the express way, rail, water, concrete mixing plant industries aggregate.
