Description
Technical field
The invention belongs to RDF preparation technologies field, and in particular to a kind of RDF stagewises crush and formation system.
Background technology
With the fast development of Chinese society's economy, domestic waste yield increasingly increases, the recycling treatment of rubbish
Having turned into must solve the problems, such as in many countries and Development of large city.The domestic waste in China is still with about 9% speed at present
Rate is incremented by, and the accumulations of a large amount of rubbish causes particularly important to garbage disposal.
We are handled rubbish using a kind of recycling, recovery energy mode, and domestic waste is prepared into
RDF.Due to the domestic waste complicated component in China, the mechanical sorting of rubbish is difficult to reach ideal effect again, so as to RDF
Follow-up preparation propose higher requirement.And disintegrating machine and forming machine are combined into a system, it can prepare preferably
RDF products, and improve production efficiency.Currently almost there is preferable effect without a kind of preparation follow-up to its of system.
The broken of rubbish is to prepare link mostly important in RDF, to the broken effect of rubbish in existing refuse grinder
Fruit is not ideal enough.Not ideal enough due to separating effect, during refuse breaking, different materials has different characteristics,
In actual implementation process, be not added with distinguishing arrives the coarse crushing of rubbish and the unification of fine shattering process together, for rigid material
With soft material it is broken not enough completely, not only treatment effect is very poor, and the loss for equipment is very big, such as the mill of cutter
Damage, work period are reduced, and increase production cost.
Current forming machine problems faced is exactly that the viscoplasticity of rubbish material causes forming machine to feed and be advanced in material
Blockage problem in journey, not only produces infringement to motor, and shaping efficiency on forming machine and Forming Quality influence it is very big.
