1. Sizers Crusher before 1990
Before the 1990s, the technology of sizers device has defects admire being not dominant the particle size of crushed product, crushed product over crushing amount, the large impact load of the body , easy harm to the broken teeth, large noise ,large maintenance procedure and different shortcomings. thus on forestall the material from the miscellaneous wood, iron, waste rock, rock arduous materials to interrupt the broken teeth, in single toothed roll crusher crushing plate bottom is equipped tension spring, a double toothed roll crusher broken with compression spring on every ends of the roller. the aim is to extend the force of the crushing plate or the roller once the crushing cavity of the bulk material or the arduous material can't be broken. thus the compression spring can increase the discharge gap of the crushing chamber thus on discharge laborious objects. Then the restoring force of the spring makes the movable crushing plate or tooth roller return to the initial position. so it cannot strictly management the particle size of the broken products. 2. Sizers Crusher after 1990
During the 1990s, with China's reform and beginning up, the coal income marketplace has moreover passed through satisfactory changes. oldsters trace at better wishes for coal education generation and equipment. It consists of the discount of high-quality particle content, the uniformity of product particle size, the discount of over-restrict particle size, and consequently the boom of manner capacity, which promotes the occasion and development of tool generation. Firstly, 2PL collection strong crusher is developed. The technical development of the crusher is mainly the cancellation of the primary double roll crusher yield spring protection tool, the double crushing curler fixed, crushing enamel exploitation new generation and substances to prevent the damage of laborious crushing enamel, consequently on strict control the massive debris in the damaged products.
