The crushing process creates a minimum of fines in the product and can also handle sticky and/or wet material without clogging of the rolls. The machines can be employed for medium hard material types up to 200 MPa compressive strength; for example: coal, ore, line, overburden and oil sands. TAKRAF has.
Gundlach's roll crushers deliver higher quality cubical product, minimal fines and consistently repeatable performance for sizing coal, coke, glass, fertilizer, potash, salts, lime, line, soft ores, friable materials and industrial minerals. Advantages & Benefits: The only crusher able to produce cubical product with uniform.
Single Roll Crushers are primary crushers that provide a crushing ratio of up to 6:1. They reduce materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., from large size particles to a medium size, while producing minimal fines. Designed with an interrupted opening between the roll teeth.
McLanahan Double Roll Crushers provide a 4:1 reduction ratio and are typically used as secondary or tertiary crushers for materials such as ROM coal, line, gypsum, trona, shale, bauxite, oil shale, clean coal, coke, salt, lime, glass, kaolin, brick, shale, and wet, sticky feeds. They can also be used following other.

size acceptable to the customer, and a minimum yield of the less valuable fines. Coke fines can be kept at a minimum by choosing the proper coal, or coal blend, and by using a coke crusher designed to produce a minimum of screenings. A combination of the proper coal and a well designed crusher can increase the yield.
The American Pulverizer Double Roll Crusher is ideal for primary and secondary reduction of ROM coal, washed coal, middlings, screenings, slag, moist clay, line, cement, potash, rock, sulfur, lignite, pyrite, and other materials where minimum fines are required. American Pulverizer brings over a century of experience.
Our company then only manufactured Double Roll Crushers as we have found that this type of crusher gives the best results for correct sizing while having the lowest power consumption and fines generation. While specializing in coal crushing, we are able to design and manufacture crushers to crush other brittle materials.
At this moisture level the greatest compression strength gains were observed, and low amounts of fines produced in impact and abrasion tests. The minimum amount of binder added while still obtaining a strong briquette was 0.5% binder A. For binder B the optimum moisture level was also 12% and the minimum amount of.
Designed Use Roll crushers handle very abrasive material with minimal wear, and can crush at ratios up to 8 to 1, depending on product characteristics, roll speed, differential speed if any, and roll gap. The roll gap is adjustable from 1 mm (very low throughput and maximum fines) to 30 mm gap for very high throughput with.
Aug 23, 2016 . The oversize particles are crushed and screened separately or the crushed coal is recycled again to the same pneumatic classifier. This scheme avoids overcrushing of the fine-coal fraction and also gives opportunity to crush hard coal particles to a finer size. A less effective process as compared to.
