It was on March 31.I received an inquiry for Crusher from Mr. Valery Borisov ,the boss of a Russia transportation company.He needs SWP 630 crusher.The raw material are PVC window sill and PVC frame and the capacity is about 650kg/h.He is also interested in SJZ65/132 and SJZ80/156 conical twin screw extruder.I send our quotation for SWP 630 Crusher and extruders to him soon.He is satisfied with our offer,and prepared contract on May 24.
On May 26,He sent me a picture.I found it is PC series Crusher.I asked some information about raw material and capacity
1. Raw material:PVC window sill and PVC frame
2. Max.Size of raw material:650mm(width)*4mm(thickness)
I prepared details of PC800 crusher,which is suitable of his request.As PC Crusher has big inlet,such design is good for big size material.As well as the blades,they are different from SWP crusher.The blades of PC crusher are the type of pieces.The conacting part with material is much larger than SWP crusher.so thery are more durable.Gernerally,the blades of PC crusher can be used about 1-2 years,and SWP crusher is usually 3-6months.We also equipped with fan and silo to make our customer more convenient to collect finished PVC flakes.And he also changed SJZ65 and 80 conical twin screw extruder to SJZ55 conical twin screw extruder,as he wanted to produce small PVC profiles.
He has visited another factory which brought our machines and worked well in Russia.so he sent me contract several days later after I quoted.
By some modification about contract,we finally finished it on June 15 and paid deposit on June 18.
On July 15,the PC800 crusher and SJZ55/110 conical twin screw extruder has been tested in our factory and sent pictures&video to him.He is satified with them.Now I am preparing delivery.
